Constants ¶
const ( JwtTokenCheck = "JwtToken" RoleCheck = "AuthCheckRole" PermissionCheck = "PermissionAction" )
Well-known keys the host registers under with SetMiddleware. An application that wants to reuse the host's own authentication and authorization chain - rather than build its own - looks these up through GetHandlerFunc instead of importing the host package that built them.
All three keys are expected to store a gin.HandlerFunc. That is a change from an earlier host convention where the JWT key stored an unbound method expression: a value with no receiver bound to it, which a caller cannot turn into a working gin.HandlerFunc no matter how it type-asserts. Hosts must register a bound closure (for example authMiddleware.MiddlewareFunc(), not (*jwt.GinJWTMiddleware).MiddlewareFunc) so all three keys have the same shape and GetHandlerFunc works uniformly across them.
const DefaultTenant = "default"
DefaultTenant 默认租户标识符

Functions ¶
func NewCache ¶
func NewCache(prefix string, store storage.AdapterCache, wxTokenStoreKey string) storage.AdapterCache
NewCache 创建对应上下文缓存
func NewQueue ¶
func NewQueue(prefix string, q storage.AdapterQueue) storage.AdapterQueue
NewQueue 创建对应上下文队列
A nil q yields a fresh in-process queue, which is almost never what a caller wants: it works, but it is private to the returned handle, so a consumer registered through one call never sees what another publishes. Application.GetQueuePrefix passes a shared queue for exactly this reason.
Types ¶
type Application ¶
type Application struct {
// contains filtered or unexported fields
}
func (*Application) AppRoutersSealed ¶ added in v2.4.0
func (e *Application) AppRoutersSealed() bool
AppRoutersSealed reports whether RunAppRouters has run. A registration made after that point is dropped, so an installer can ask rather than find out from a log line.
func (*Application) BeforeSealed ¶ added in v2.4.0
func (e *Application) BeforeSealed() bool
BeforeSealed reports whether RunBefore has run. A registration made after that point is dropped, so an installer can ask rather than find out from a log line.
func (*Application) BeginShutdown ¶ added in v2.6.0
func (e *Application) BeginShutdown()
BeginShutdown says that the application is on its way out, and closes the phases that only make sense on the way in.
It exists because the last configuration reload can outlive the decision to stop. Closing the config watcher does not wait for a reload already in flight, and that reload finishes by rebuilding the database, the cache and the queue and announcing them - which, in the middle of a shutdown, undoes the cleanup that has just run and starts consumers on a process that is being taken apart. AfterResource is also the one phase that never closes, so without this there is nothing to stop code registering into it while the process is going down.
After this call SetPhase and RunPhase do nothing for every phase but BeforeExit, and say so. BeforeExit keeps working: it is the phase this call is on the way to. There is no way back - a process does not un-shut-down - and calling it twice is harmless.
It does not interrupt a phase already running. It closes the door; it does not reach into the room.
RunShutdown calls it, so a host that only calls RunShutdown is covered from that moment on. Calling it as the first step of the shutdown path is what covers the window before then, which is the wider one: it spans the whole of the HTTP server's own graceful shutdown.
func (*Application) GetAllCasbin ¶
func (e *Application) GetAllCasbin() map[string]*casbin.SyncedEnforcer
GetAllCasbin 获取所有租户的casbin (原GetCasbin改名)
func (*Application) GetAllCrontab ¶
func (e *Application) GetAllCrontab() map[string]*cron.Cron
GetAllCrontab 获取所有租户的定时任务 (原GetCrontab改名)
func (*Application) GetAllDb ¶
func (e *Application) GetAllDb() map[string]*gorm.DB
GetAllDb 获取所有租户的数据库 (原GetDb改名) GetAllDb returns a snapshot. Handing back the map itself was a race the lock could not fix: it was held across the return and released before the caller read anything.
func (*Application) GetAllHandler ¶
func (e *Application) GetAllHandler() map[string][]func(r *gin.RouterGroup, hand ...*gin.HandlerFunc)
func (*Application) GetAllMiddleware ¶
func (e *Application) GetAllMiddleware() map[string]interface{}

GetApp 获取所有map里的app数据
func (*Application) GetAppByTenant ¶
func (e *Application) GetAppByTenant(tenant string) interface{}
GetAppByTenant 根据key获取app
func (*Application) GetAppRouters
deprecated
func (e *Application) GetAppRouters() []func()
GetAppRouters returns the registered router initialisers, in registration order.
Deprecated: use RunAppRouters. Running the returned callbacks yourself gets no panic guard and no failure levels, and core cannot see your loop: calling RunAppRouters afterwards runs everything a second time.
func (*Application) GetBefore
deprecated
func (e *Application) GetBefore() []func()
GetBefore returns the registered before callbacks, in registration order.
Deprecated: use RunBefore. Running the returned callbacks yourself gets no panic guard and no failure levels, and core cannot see your loop: calling RunBefore afterwards runs everything a second time.
func (*Application) GetCacheAdapter ¶
func (e *Application) GetCacheAdapter() storage.AdapterCache
GetCacheAdapter 获取缓存
func (*Application) GetCacheAdapterPrefix ¶
func (e *Application) GetCacheAdapterPrefix(prefix string) storage.AdapterCache

GetCasbinByTenant 根据租户获取casbin
func (*Application) GetCasbinExclude ¶
func (e *Application) GetCasbinExclude() map[string]interface{}
GetCasbinExclude 获取所有map里的Exclude数据
func (*Application) GetCasbinExcludeByTenant ¶
func (e *Application) GetCasbinExcludeByTenant(tenant string) interface{}

GetConfigValueByTenant 获取对应租户的config
func (*Application) GetCrontab ¶
func (e *Application) GetCrontab() *cron.Cron
GetCrontab 获取默认租户的定时任务 (新增单租户快捷方法)
func (*Application) GetCrontabByTenant ¶
func (e *Application) GetCrontabByTenant(tenant string) *cron.Cron
GetCrontabByTenant 根据租户获取crontab
func (*Application) GetDbByTenant ¶
func (e *Application) GetDbByTenant(tenant string) *gorm.DB
GetDbByTenant 根据租户获取db
func (*Application) GetDefaultTenant ¶
func (e *Application) GetDefaultTenant() string
GetDefaultTenant 获取默认租户
func (*Application) GetHandler ¶
func (e *Application) GetHandler() []func(r *gin.RouterGroup, hand ...*gin.HandlerFunc)
func (*Application) GetHandlerByTenant ¶
func (e *Application) GetHandlerByTenant(tenant string) []func(r *gin.RouterGroup, hand ...*gin.HandlerFunc)
func (*Application) GetHandlerFunc ¶ added in v2.5.0
func (e *Application) GetHandlerFunc(key string) (gin.HandlerFunc, bool)
GetHandlerFunc is GetMiddleware plus the type assertion every caller of it otherwise has to repeat, and a reported failure instead of a panic when the key was never registered or was registered with something other than a gin.HandlerFunc.
The bool result exists because a bare type assertion turns two different, unrelated problems - "not registered yet" and "registered with the wrong shape" - into a panic at the call site, typically inside a router initialiser that runs behind this framework's panic guard (see docs/contract.md section 4), which then reports the module as having failed to register any routes at all rather than naming the real cause. Callers that need JWT enforcement to be non-optional should still check ok explicitly and fail loudly, since a missing middleware is not a state a router should silently continue past.
func (*Application) GetMemoryQueue
deprecated
func (e *Application) GetMemoryQueue(prefix string) storage.AdapterQueue
GetMemoryQueue returns the in-process queue.
Deprecated: use GetQueuePrefix. This always returns the in-process queue, whatever the configuration selected, so messages published through it are invisible to every other instance.
func (*Application) GetMiddleware ¶
func (e *Application) GetMiddleware(key string) interface{}
GetMiddleware 获取对应的中间件
func (*Application) GetQueue ¶
func (e *Application) GetQueue() storage.AdapterQueue
GetQueue 获取默认租户的队列
func (*Application) GetQueueAdapter ¶
func (e *Application) GetQueueAdapter() storage.AdapterQueue
GetQueueAdapter 获取队列适配器
func (*Application) GetQueuePrefix ¶
func (e *Application) GetQueuePrefix(key string) storage.AdapterQueue
GetQueuePrefix 获取标记的queue
This is the queue the configuration selected. Prefer it over GetMemoryQueue, which ignores configuration and never leaves the process.
func (*Application) GetStreamMessage ¶
func (e *Application) GetStreamMessage(id, stream string, value map[string]interface{}) (storage.Messager, error)
GetStreamMessage 获取队列需要用的message
func (*Application) PhaseSealed ¶ added in v2.6.0
func (e *Application) PhaseSealed(p Phase) bool
PhaseSealed reports whether p has already run, i.e. whether a further SetPhase for it would be dropped.
AfterResource always reports false: it is re-entrant, so registering into it is never too late - though a callback that arrives after the last reload of the process will not run until the next one.
A phase that is not one of the four constants reports true: "your callback will not run in that phase" is the answer that keeps a caller from registering into a hole, and it is also reported, because asking about a phase that does not exist is a mistake in the caller either way.
func (*Application) RunAppRouters ¶ added in v2.4.0
func (e *Application) RunAppRouters()
RunAppRouters executes every router initialiser that has not run yet, in registration order, and closes the registry to further registration.
Calling it again is a no-op: the initialisers that already ran do not run twice.
func (*Application) RunBefore ¶ added in v2.4.0
func (e *Application) RunBefore()
RunBefore executes every before callback that has not run yet, in registration order, and closes the registry to further registration.
Calling it again is a no-op: the callbacks that already ran do not run twice.
func (*Application) RunPhase ¶ added in v2.6.0
func (e *Application) RunPhase(p Phase)
RunPhase executes the callbacks registered for p, in registration order.
The callbacks run with no lock held, because they routinely call back into Application and sync.RWMutex is not reentrant. A p that is not one of the four constants is reported and does nothing.
For every phase but AfterResource this happens once: the phase is closed to further registration afterwards, and calling RunPhase again is a no-op, so cleanup registered in BeforeExit cannot run twice.
BeforeExit is the other exception, in the other direction: it runs in reverse registration order, because it is the phase that unwinds. See SetShutdown, which registers into the same phase and is how a callback that wants the remaining budget asks for it.
AfterResource is the exception, because the resources it announces are rebuilt on every configuration reload. It never closes, every registered callback runs again on every round, and a callback that arrives while a round is running is picked up by the next one. Two rounds never overlap: a trigger that arrives during a round records that another round is owed and returns without waiting for it, which makes RunPhase(AfterResource) the one case that can return before the work is done. See runReentrant.
func (*Application) RunShutdown ¶ added in v2.6.0
func (e *Application) RunShutdown(ctx context.Context) error
RunShutdown runs the BeforeExit callbacks, in reverse registration order, within the caller's context, and closes the phase.
It returns ctx.Err() if the context ends first, and nil otherwise. Calling it again runs nothing: cleanup that already ran does not run twice, because closing a connection pool twice is worse than not closing it.
What the context bounds is the wait, not the work. The callbacks run on their own goroutine; when the budget is gone this method stops waiting and returns, and the callback that is running carries on until the process exits - possibly leaving whatever it was writing half-written. There is no way to do better: Go cannot cancel a function that does not check for it, which is why the callbacks are handed a context in the first place. The callback holding things up is named in the log.
With nothing registered it returns nil immediately, without a goroutine and without consulting the context: nothing to run is not a timeout.
func (*Application) SetAppByTenant ¶
func (e *Application) SetAppByTenant(key string, app interface{})
SetAppByTenant 设置对应租户的app
func (*Application) SetAppRouters ¶
func (e *Application) SetAppRouters(appRouters func())
SetAppRouters registers a router initialiser for an application module.
The callback runs when RunAppRouters is called, in registration order, behind a panic guard. Registering after RunAppRouters has run is refused and reported.
func (*Application) SetAppRoutersWith ¶ added in v2.4.0
func (e *Application) SetAppRoutersWith(appRouters func(), opts ...CallbackOption)
SetAppRoutersWith registers a router initialiser and configures how a panic in it is treated. With no options it is identical to SetAppRouters.
func (*Application) SetBefore ¶
func (e *Application) SetBefore(f func())
SetBefore registers a callback to run before the server starts.
The callback runs when RunBefore is called, in registration order, behind a panic guard. Registering after RunBefore has run is refused and reported.
func (*Application) SetBeforeWith ¶ added in v2.4.0
func (e *Application) SetBeforeWith(f func(), opts ...CallbackOption)
SetBeforeWith registers a before callback and configures how a panic in it is treated. With no options it is identical to SetBefore.
func (*Application) SetCacheAdapter ¶
func (e *Application) SetCacheAdapter(c storage.AdapterCache)
SetCacheAdapter 设置缓存
func (*Application) SetCasbin ¶
func (e *Application) SetCasbin(enforcer *casbin.SyncedEnforcer)
SetCasbin 设置默认租户的casbin
func (*Application) SetCasbinByTenant ¶
func (e *Application) SetCasbinByTenant(tenant string, enforcer *casbin.SyncedEnforcer)
func (*Application) SetCasbinExclude ¶
func (e *Application) SetCasbinExclude(list interface{})
SetCasbinExclude 设置默认租户的Exclude
func (*Application) SetCasbinExcludeByTenant ¶
func (e *Application) SetCasbinExcludeByTenant(tenant string, list interface{})
SetCasbinExcludeByTenant 设置对应租户的Exclude
func (*Application) SetConfigByTenant ¶
func (e *Application) SetConfigByTenant(tenant string, value map[string]interface{})
SetConfigByTenant 设置对应租户的config
func (*Application) SetConfigValue ¶
func (e *Application) SetConfigValue(key string, value interface{})
SetConfigValue 设置默认租户的配置值
func (*Application) SetConfigValueByTenant ¶
func (e *Application) SetConfigValueByTenant(tenant, key string, value interface{})
SetConfigValueByTenant 设置对应租户的key的config
func (*Application) SetCrontab ¶
func (e *Application) SetCrontab(crontab *cron.Cron)
SetCrontab 设置默认租户的crontab
func (*Application) SetCrontabByTenant ¶
func (e *Application) SetCrontabByTenant(key string, crontab *cron.Cron)
SetCrontabByTenant 设置对应租户的crontab
func (*Application) SetDbByTenant ¶
func (e *Application) SetDbByTenant(tenant string, db *gorm.DB)
SetDbByTenant 设置对应租户的db
func (*Application) SetDefaultTenant ¶
func (e *Application) SetDefaultTenant(tenant string)
SetDefaultTenant 设置默认租户
func (*Application) SetEngine ¶
func (e *Application) SetEngine(engine http.Handler)
SetEngine 设置路由引擎
An app router callback is allowed to call this - the demo module does, on the path where no engine has been set yet - so the field is written after the server has started reading it elsewhere, and needs the lock.
func (*Application) SetHandler ¶
func (e *Application) SetHandler(routerGroup func(r *gin.RouterGroup, hand ...*gin.HandlerFunc))
func (*Application) SetHandlerByTenant ¶
func (e *Application) SetHandlerByTenant(tenant string, routerGroup func(r *gin.RouterGroup, hand ...*gin.HandlerFunc))
func (*Application) SetMiddleware ¶
func (e *Application) SetMiddleware(key string, middleware interface{})
SetMiddleware 设置租户中间件
func (*Application) SetPhase ¶ added in v2.6.0
func (e *Application) SetPhase(p Phase, f func(), opts ...CallbackOption)
SetPhase registers a callback to run when the application reaches p.
The callback runs when RunPhase(p) is called, in registration order, behind the same panic guard as SetBefore: a panic is logged with the registration site and the remaining callbacks still run, unless WithFatal says otherwise.
Registering after that phase has already run is refused and reported, and so is a p that is not one of the four constants - neither panics, because an installer registering a hook is usually running inside an init() where a panic takes the whole program down and names this file rather than the caller. Ask PhaseSealed if you need to know rather than read it in a log.
func (*Application) SetQueueAdapter ¶
func (e *Application) SetQueueAdapter(c storage.AdapterQueue)
SetQueueAdapter 设置队列适配器
Reloading the configuration calls this again while requests are in flight, so the field is guarded.
func (*Application) SetShutdown ¶ added in v2.6.0
func (e *Application) SetShutdown(f func(context.Context), opts ...CallbackOption)
SetShutdown registers a callback to run on the way out, once the server has stopped serving.
It is the context-taking half of SetPhase(BeforeExit, ...): both register into the same phase, and one pass runs both. The context carries whatever budget the host allowed for shutdown, so a callback that can cut its work short - drain for what is left rather than for a fixed time - has something to look at. One that cannot is free to ignore it.
The callbacks run in reverse registration order, which is the right default for a chain of hooks that built on each other: the last one registered is the one most likely to depend on the others. It says nothing about resources the host created for itself, which were not built by this chain and are not unwound by it.
WithFatal is not honoured here, and saying so is the point: exiting from inside cleanup skips every callback after it, which is the opposite of what the option is for. The callback is kept and the option is reported, because refusing the registration would mean one mistyped option costs you the cleanup entirely - silently.
type Cache ¶
type Cache struct {
// contains filtered or unexported fields
}
type CallbackOption ¶ added in v2.4.0
type CallbackOption func(*callbackConfig)
CallbackOption configures a callback registered through SetBeforeWith or SetAppRoutersWith.
Passing no options is the historical behaviour: a panic is logged and the remaining callbacks still run. Nothing a caller does not ask for changes.
func WithFatal ¶ added in v2.4.0
func WithFatal() CallbackOption
WithFatal marks a callback the process must not start without: a panic in it is logged and then the process exits with status 1.
This is the exception, not the default. An application that marks itself fatal makes the whole host program as fragile as itself, and the exit skips every deferred cleanup - so it only belongs on work that happens before the server starts listening.
func WithName ¶ added in v2.4.0
func WithName(name string) CallbackOption
WithName labels the callback in guard logs. Without it the log carries the registration site only, which is enough to find the code but not enough to know what it was for.
type Phase ¶ added in v2.6.0
type Phase int
Phase names a point in the life of the application that a module can attach work to.
The values are assigned explicitly rather than with iota, and with gaps: a phase inserted later takes a number in a gap instead of moving the numbers already compiled into somebody else's binary, so p1 < p2 keeps meaning "p1 is reached first".
That orders the first pass and nothing else. AfterResource runs again on every configuration reload, so for the rest of the process's life it happens after AfterListen while still holding the smaller number: < cannot answer "has that phase already run". PhaseSealed can.
The numbers themselves are an implementation detail. They are not part of the contract, and must not be persisted, sent over the wire, or written into configuration - name the constant instead.
const ( // AfterResource is reached once the database, cache, queue and casbin // enforcer have been built from the configuration that is current at that // moment. // // It is the one phase that runs more than once: a configuration reload // rebuilds those resources, and the point of the phase is to give the // code that depends on them a chance to attach itself to the new ones. A // hook registered here must therefore be written to run repeatedly - see // RunPhase for what "repeatedly" is allowed to mean. AfterResource Phase = 10 // BeforeRouter is reached before the router is initialised, which is the // last point at which a module can still affect how routes are built. // // It is not the same point as the SetBefore registry: those callbacks run // after the router has been initialised, not before it. BeforeRouter Phase = 20 // AfterListen is reached once the listening socket is accepting // connections - not merely once the goroutine that serves it was started. // A hook here can rely on the port being bound, because a failure to bind // has already been reported by then. AfterListen Phase = 30 // BeforeExit is reached after the HTTP server has been shut down and // before the process returns, for work that must happen on the way out // but does not need the server. // // It is not a place to drain a load balancer: by the time it runs the // listener is already closed, so anything that depends on still being // reachable belongs somewhere this package does not currently offer. BeforeExit Phase = 40 )
