var ( ErrInternalServerError = &ErrCode{Err: 50010000, Msg: "服务器内部错误"} ErrInvalidParam = &ErrCode{Err: 40010001, Msg: "请求参数不正确"} ErrNotFound = &ErrCode{Err: 40410002, Msg: "资源不存在"} ErrMethodNotAllow = &ErrCode{Err: 40510003, Msg: "方法不允许"} )
Functions ¶
func Errorf ¶
Errorf formats according to a format specifier and returns the string as a value that satisfies error. Errorf also records the stack trace at the point it was called.
func New ¶
New returns an error with the supplied message. New also records the stack trace at the point it was called.
func WithStack ¶
WithStack annotates err with a stack trace at the point WithStack was called. If err is nil, WithStack returns nil.
Types ¶
type ErrCode ¶
ErrCode 规定组成部分为http状态码+5位错误码
func (*ErrCode) StatusCode ¶
func (*ErrCode) WithMessage ¶
type Frame ¶
type Frame uintptr
Frame represents a program counter inside a stack frame. For historical reasons if Frame is interpreted as an uintptr its value represents the program counter + 1.
func (Frame) Format ¶
Format formats the frame according to the fmt.Formatter interface.
%s source file %d source line %n function name %v equivalent to %s:%d
Format accepts flags that alter the printing of some verbs, as follows:
%+s function name and path of source file relative to the compile time
GOPATH separated by \n\t (<funcName>\n\t<path>)
%+v equivalent to %+s:%d
func (Frame) MarshalText ¶
MarshalText formats a stacktrace Frame as a text string. The output is the same as that of fmt.Sprintf("%+v", f), but without newlines or tabs.
type StackTrace ¶
type StackTrace []Frame
StackTrace is stack of Frames from innermost (newest) to outermost (oldest).
func (StackTrace) Format ¶
func (st StackTrace) Format(s fmt.State, verb rune)
Format formats the stack of Frames according to the fmt.Formatter interface.
%s lists source files for each Frame in the stack %v lists the source file and line number for each Frame in the stack
Format accepts flags that alter the printing of some verbs, as follows:
%+v Prints filename, function, and line number for each Frame in the stack.
type UnwrapHandle ¶
type UnwrapHandle interface {
Unwrap() error
}
