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)
