log包写文件的时候有没有必要开启协程去处理？

改协程比较好

package dogger

import (
    "log"
    "net/http"
    "bytes"
)

type Ding struct {
    WebHookUrl string
}

func (d *Ding) Write(p []byte) (n int, err error) {
    //remove last \n byte
    p = p[:len(p)-2]
    buf := bytes.NewBufferString(`{"msgtype":"text","text":{"content":"`)
    buf.Write(p)
    buf.WriteString(`"}}`)
    //发功日志到钉钉群机器人
    go http.Post(d.WebHookUrl, "application/json", buf)
    return 0, err
}

var logger *log.Logger

func NewLogger(hookUrl string) *log.Logger {
    dingDingTalker := Ding{hookUrl}
    logger = log.New(&dingDingTalker, "eric:", log.Lshortfile | log.LstdFlags)
    return logger
}

func Println(v ...interface{}) {
    if logger == nil {
        log.Fatal("请设置钉钉bot Web Hook Url")
    }
    logger.Println(v)
}
