Gin框架-自定义路由日志的格式

默认的路由日志是这样的:

[GIN-debug] POST   /foo                      --> main.main.func1 (3 handlers)
[GIN-debug] GET    /bar                      --> main.main.func2 (3 handlers)
[GIN-debug] GET    /status                   --> main.main.func3 (3 handlers)

如果你想以给定的格式记录这些信息(例如 JSON,键值对或其他格式),你可以使用gin.DebugPrintRouteFunc来定义格式,在下面的示例中,我们使用标准日志包记录路由日志,你可以使用其他适合你需求的日志工具

import (
    "log"
    "net/http"

    "github.com/gin-gonic/gin"
)

func main() {
    r := gin.Default()
    gin.DebugPrintRouteFunc = func(httpMethod, absolutePath, handlerName string, nuHandlers int) {
        log.Printf("endpoint %v %v %v %v\n", httpMethod, absolutePath, handlerName, nuHandlers)
    }

    r.POST("/foo", func(c *gin.Context) {
        c.JSON(http.StatusOK, "foo")
    })

    r.GET("/bar", func(c *gin.Context) {
        c.JSON(http.StatusOK, "bar")
    })

    r.GET("/status", func(c *gin.Context) {
        c.JSON(http.StatusOK, "ok")
    })

    // Listen and Server in http://0.0.0.0:8080
    r.Run()
}
