全局gin对象如何在子模块中修改Logger
gin是通过中间件写日志, 日志对象是中间件的闭包变量。在use加载中间件完成之后，无法修改日志对象。 该如何办呢？
一般设置方法
以下是设置gin日志的方法
#方法一gin.DefaultWriter = xxxgin.DefaultErrorWriter = xxx app := gin.Default()app.Use(xxx)#方法二app := gin.Default()app.Use(gin.LoggerWithWriter(xxx)) |
当情况发生变化
1. app := gin.Default()被放在了顶层模块，并且加载了默认中间件
2. 程序真正的log在子模块中初始化
3. 在子模块中如何修改gin的日志？
借助zapio.Writer对象，通过修改它的Log属性实现
# 顶层模块gin.gogin.DefaultWriter =&zapio.Writer{Log:zap.L()}gin.DefaultErrorWriter = gin.DefaultWriterapp := gin.Default()app.use(xxx)#子模块xxx/sim/http.goif gl, ok := gin.DefaultWriter.(*zapio.Writer);ok{gl.Log = gs.log.Desugar() #修改Log属性} |
