Recover
Recover 中间件会从链中任意位置的 panic 中恢复,打印堆栈跟踪,并把控制权传给集中式 HTTPErrorHandler。
e.Use(middleware.Recover())e := echo.New()e.Use(middleware.RecoverWithConfig(middleware.RecoverConfig{ StackSize: 1 << 10, // 1 KB}))上面的示例使用 StackSize 为 1 KB,并对 DisableStackAll 和 DisablePrintStack 使用默认值。
type RecoverConfig struct { // Skipper defines a function to skip middleware. Skipper Skipper
// Size of the stack to be printed. // Optional. Default value 4KB. StackSize int
// DisableStackAll disables formatting stack traces of all other goroutines // into the buffer after the trace for the current goroutine. // Optional. Default value false. DisableStackAll bool
// DisablePrintStack disables printing the stack trace. // Optional. Default value false. DisablePrintStack bool}var DefaultRecoverConfig = RecoverConfig{ Skipper: DefaultSkipper, StackSize: 4 << 10, // 4 KB DisableStackAll: false, DisablePrintStack: false,}
