12.3. 请求上下文日志

package main

/*
Context接口中日志相关方法。
type Context interface {
    ...
    Debug(...interface{})
    Info(...interface{})
    Warning(...interface{})
    Error(...interface{})
    Fatal(...interface{})
    Debugf(string, ...interface{})
    Infof(string, ...interface{})
    Warningf(string, ...interface{})
    Errorf(string, ...interface{})
    Fatalf(string, ...interface{})
    WithField(key string, value interface{}) Logout
    WithFields(fields Fields) Logout
    Logger() Logout
}

ctx.Fatal会返回状态码500和err的内容。
例如： {"error":"fatal logger method: GET path: /err","status":"500","x-request-id":""}
