contextLogger.go

package main

/*
Context接口中日志相关方法，与Logger接口方法几乎完全一致。
type Context interface {
	...
	Debug(...any)
	Info(...any)
	Warning(...any)
	Error(...any)
	Fatal(...any)
	Debugf(string, ...any)
	Infof(string, ...any)
	Warningf(string, ...any)
	Errorf(string, ...any)
	Fatalf(string, ...any)
	WithField(string, any) Logger
	WithFields([]string, []any) Logger
}

middleware.NewRequestIDFunc(nil) 会自动将X-Request-Id写入日志Field。
行为区别在于ctx.Fatal()方法会调用ctx.End()方法结束处理和返回错误内容数据。
例如：
{
	"time": "2024-06-03 10:12:51.245",
	"host": "",
	"method": "GET",
	"path": "/err",
	"route": "/err",
	"status": 500,
	"x-request-id": "1717380771245684456-05c419",
	"error": "fatal logger method: GET path: /err"
}
