8年前
Recover是一个HTTP中间件，能够捕捉任何panics并提供一个适当的错误响应。
适用于所有框架，支持原生http handler (eg. Echo, Goji).
安装
$ go get github.com/dre1080/recover
用法
package main import ( "log" "net/http" "github.com/dre1080/recover" ) var myPanicHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { panic("you should not have a handler that just panics ;)") }) func main() { recovery := recover.New(&recover.Options{ Log: log.Print, }) // recoveryWithDefaults := recovery.New(nil) app := recovery(myPanicHandler) http.ListenAndServe("0.0.0.0:3000", app) }Terminal
