Constants ¶
const AppleAppSiteAssociationPath = "/.well-known/apple-app-site-association"
AppleAppSiteAssociationPath is the well-known path iOS fetches to discover a domain's Universal Link configuration. Apple requires it be served over HTTPS with no redirects and a JSON content type.
See https://developer.apple.com/documentation/xcode/supporting-associated-domains.

Functions ¶
func AppleAppSiteAssociationHandler ¶ added in v7.1.0
func AppleAppSiteAssociationHandler( cfg *AppleAppSiteAssociationConfig, logger logging.Logger, tracerProvider tracing.TracerProvider, ) http.HandlerFunc
AppleAppSiteAssociationHandler returns an http.HandlerFunc that serves the apple-app-site-association document described by cfg. Register it at AppleAppSiteAssociationPath; NewHTTPServer does so automatically when Config.AppleAppSiteAssociation is enabled, so this is only needed to serve the document from somewhere else (a different mux, a CDN origin, etc).
A config that is empty or malformed yields a handler that responds 404, so callers never have to branch on whether the feature is configured.
func RegisterHTTPServer ¶
RegisterHTTPServer registers a Server with the injector. The serviceName parameter is passed directly rather than injected, since string is too generic a type to resolve unambiguously from the injector.
func RootLevelAssetsHandler ¶
func RootLevelAssetsHandler(assetsDir string) http.HandlerFunc
RootLevelAssetsHandler returns an http.HandlerFunc that serves static files from assetsDir. It only serves root-level files (no subdirectories) and guards against path traversal. Register with router.Get("/*", RootLevelAssetsHandler(assetsDir)) as the last route.
Types ¶
type AppleAppSiteAssociationConfig ¶ added in v7.1.0
type AppleAppSiteAssociationConfig struct {
// TeamID is the Apple Developer Team ID (e.g. "ABCD1234XY").
TeamID string `env:"TEAM_ID" json:"teamID,omitempty" yaml:"teamID,omitempty"`
// BundleID is the iOS app bundle identifier (e.g. "com.example.ios").
BundleID string `env:"BUNDLE_ID" json:"bundleID,omitempty" yaml:"bundleID,omitempty"`
// Paths restricts which URL paths open the app, as Apple component patterns
// (e.g. "/invitations/*"). Empty grants every path on the domain, which is what a
// service with no opinion wants; set it when only part of the site should deep-link
// into the app.
Paths []string `env:"PATHS" json:"paths,omitempty" yaml:"paths,omitempty"`
// WebCredentials adds the webcredentials service to the document, which is what
// lets iOS offer Password AutoFill and shared credentials for this domain. It is
// off by default: a domain claims it only when the app's entitlements list a
// matching "webcredentials:" associated domain.
WebCredentials bool `env:"WEB_CREDENTIALS" json:"webCredentials,omitempty" yaml:"webCredentials,omitempty"`
// contains filtered or unexported fields
}
AppleAppSiteAssociationConfig holds the configuration for the apple-app-site-association file iOS uses for Universal Links. It is optional: when TeamID and BundleID are both empty the file is not served at all, so services without an iOS app are unaffected. When either is set, both are required.
func (*AppleAppSiteAssociationConfig) Enabled ¶ added in v7.1.0
func (cfg *AppleAppSiteAssociationConfig) Enabled() bool
Enabled indicates whether the apple-app-site-association file should be served, which requires both identifiers to be present and well-formed. A malformed config reports disabled here and an error from ValidateWithContext, so a service that skips validation serves nothing rather than a document iOS would reject.
func (*AppleAppSiteAssociationConfig) ValidateWithContext ¶ added in v7.1.0
func (cfg *AppleAppSiteAssociationConfig) ValidateWithContext(ctx context.Context) error
ValidateWithContext validates an AppleAppSiteAssociationConfig struct. An entirely empty config is valid (the feature is simply off); a partially filled one is not.
Setting any field counts as intent to serve the document, including Paths or WebCredentials alone. That matters because those two are inert without the identifiers: a config that scopes paths but whose TeamID never made it out of the environment would otherwise validate clean and then quietly serve nothing.
type Config ¶
type Config struct {
// AppleAppSiteAssociation, when populated, causes the server to serve the
// apple-app-site-association file at AppleAppSiteAssociationPath.
AppleAppSiteAssociation *AppleAppSiteAssociationConfig `` /* 133-byte string literal not displayed */
SSLCertificateFile string `env:"SSL_CERTIFICATE_FILEPATH" json:"sslCertificate,omitempty" yaml:"sslCertificate,omitempty"`
SSLCertificateKeyFile string `env:"SSL_CERTIFICATE_KEY_FILEPATH" json:"sslCertificateKey,omitempty" yaml:"sslCertificateKey,omitempty"`
StartupDeadline time.Duration `env:"STARTUP_DEADLINE" json:"startupDeadline,omitempty" yaml:"startupDeadline,omitempty"`
ReadTimeout time.Duration `env:"READ_TIMEOUT" json:"readTimeout,omitempty" yaml:"readTimeout,omitempty"`
WriteTimeout time.Duration `env:"WRITE_TIMEOUT" json:"writeTimeout,omitempty" yaml:"writeTimeout,omitempty"`
IdleTimeout time.Duration `env:"IDLE_TIMEOUT" json:"idleTimeout,omitempty" yaml:"idleTimeout,omitempty"`
Port uint16 `env:"PORT" json:"port" yaml:"port"`
Debug bool `env:"DEBUG" json:"debug" yaml:"debug"`
// contains filtered or unexported fields
}
Config describes the settings pertinent to the HTTP serving portion of the service.
type Server ¶
func NewHTTPServer ¶
func NewHTTPServer( serverSettings *Config, logger logging.Logger, router *routing.Router, tracerProvider tracing.TracerProvider, serviceName string, ) (Server, error)
NewHTTPServer builds a new server instance. serverSettings may be nil, which is treated as a zero-valued Config. serviceName, when non-empty, is used for the server's logger; otherwise "api_server" is used.
