Go语言实现钉钉发送通知

具体代码如下所示：

package mainimport (  "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 2.7import timeimport hmacimport hashlibimport base64import urllibtimestamp = 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)
