Go语言实现钉钉发送通知

具体代码如下所示：

package main
import (
 "bufio"
 "io"
 "fmt"
 "io/ioutil"
 "os/exec"
 "net/http"
 "os"
 "strings"
)
func GetKey() (timestamp string ,sign string, err error){
 cmd := exec.Command("/bin/python", "/application/scripts/hezhong_host_status/aaa.py")
 stdout , err := cmd.StdoutPipe()
 if err != nil {
  fmt.Println("Error:can not obtain stdout pipe for command:％s \n", err)
  return timestamp , sign, err
 }
 if err := cmd.Start() ; err != nil {
  fmt.Println("Error:The command is err ",err)
  return timestamp, sign,err
 }
 var Key []string
 //读取所有输出
 bytes := bufio.NewReader(stdout)
 for {
  line ,err:= bytes.ReadString('\n')
  if err == io.EOF{
    break
  }
  if err != nil {
    fmt.Println("Read Err:",err)
  }
  Key = append(Key,line)
 }
 if err := cmd.Wait();err!= nil{
  fmt.Println("Wait",err.Error())
  return timestamp, sign ,err
 }
 timestamp = Key[0]
 sign = Key[1]
 return timestamp ,sign ,nil
}
func SendDingMsg(msg string) {
 //请求地址模板
 timestamp , sign , err := GetKey()
 if err != nil {
  fmt.Println("Get Key Err:",err)
 }
 timestamp = strings.TrimRight(timestamp, "\n")
 sign = strings.TrimRight(sign, "\n")
 //timestamp := time.Now().UnixNano() / 1e6
 //timestamp := int64(1572870805748)
 //sign := "oJ5SHD3IwCWVIcL78k3pgX0tfQnjDfcDZMPXAI％2BvrFE％3D"
 webHook := "https://oapi.dingtalk.com/robot/send?access_token=628d11124aef5f9efe2a8c8a6b5afa2b67ab01dxxxxxxxxxxxxxxxxxxxxx&"+ "timestamp=" + timestamp + "&sign=" + sign
 content := `{"msgtype": "text",
  "text": {"content": "`+ msg + `"},
       "at": {
          "atMobiles": [
            "18301371817"
          ],
          "isAtAll": true
       }
 }`
 //创建一个请求
 req, err := http.NewRequest("POST", webHook, strings.NewReader(content))
 if err != nil {
  fmt.Println(err)
 }
 client := &http.Client{}
 //设置请求头
 req.Header.Set("Content-Type", "application/json")
 req.Header.Set("User-agent","firefox")
 //发送请求
 resp, err := client.Do(req)
 //关闭请求
 defer resp.Body.Close()
 fmt.Println(resp.StatusCode)
 body,_ := ioutil.ReadAll(resp.Body)
 fmt.Println(string(body))
 if err != nil {
  fmt.Println("handle error")
 }
}
func main(){
 SendDingMsg(os.Args[1])
}

辅助Python脚本：

#!python 2.7
import time
import hmac
import hashlib
import base64
import urllib
timestamp = long(round(time.time() * 1000))
secret = 'this is secret'
secret_enc = bytes(secret).encode('utf-8')
string_to_sign = '{}\n{}'.format(timestamp, secret)
string_to_sign_enc = bytes(string_to_sign).encode('utf-8')
hmac_code = hmac.new(secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()
sign = urllib.quote_plus(base64.b64encode(hmac_code))
print(timestamp)
print(sign)
