tracker

用于在客户提交类的请求添加跟踪日志，可输出query、body以及params等信息，并可设置正则匹配将关键数据加*处理。

Example

package main
import (
    "bytes"
    "encoding/json"
    "fmt"
    "github.com/vicanso/elton"
    "github.com/vicanso/elton/middleware"
)
func main() {
    e := elton.New()
    loginTracker := middleware.NewTracker(middleware.TrackerConfig{
        OnTrack: func(info *middleware.TrackerInfo, _ *elton.Context) {
            buf, _ := json.Marshal(info)
            fmt.Println(string(buf))
        },
    })
    e.Use(func(c *elton.Context) error {
        c.RequestBody = []byte(`{
            "account": "tree.xie",
            "password": "123456"
        }`)
        return c.Next()
    })
    e.POST("/user/login", loginTracker, func(c *elton.Context) (err error) {
        c.SetHeader(elton.HeaderContentType, elton.MIMEApplicationJSON)
        c.BodyBuffer = bytes.NewBuffer(c.RequestBody)
        return
    })
    err := e.ListenAndServe(":3000")
    if err != nil {
        panic(err)
    }
}
