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)
