Functions

func ApiError

func ApiError(w http.ResponseWriter, code int, message string)

ApiError 错误处理code,message

func ApiSuccess

func ApiSuccess(w http.ResponseWriter, message string, data interface{})

ApiSuccess 请求成功返回结果 data,message

func ContextGet

func ContextGet(r *http.Request, key interface{}) interface{}

ContextGet 从请求上下文获取指定的key值

func ContextSet
