具体代码如下所示：

package main

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)
}

}
func senddingmsg(msg string) {

}
timestamp = strings.trimright(timestamp, "\n")

//timestamp := time.now().unixnano() / 1e6

//创建一个请求

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)
