golang 阿里云发送短信接口

1.阿里云发短信

//SendMsg 发送短信
func SendMsg(phone, msgJSON string) bool {
    body := "send msg"
    content := url.QueryEscape(msgJSON)
    signString := setQueryStr(phone, content, "13223334554545")
    singstr := signLinaJie + url.QueryEscape(signString)
    sign := hmac4Go(singstr, sk+lianJIe)
    client := &http.Client{}
    var req *http.Request
    req, err = http.NewRequest("GET", requestURL+url.QueryEscape(sign)+lianJIe+signString, strings.NewReader(body))
    var resp *http.Response
    resp, err = client.Do(req)
    if err != nil {
        fmt.Println("http get error.", err)
        return false
    }
    fmt.Println(resp.Body)
    defer resp.Body.Close()
    var bodys []byte
    bodys, err = ioutil.ReadAll(resp.Body)
    if err != nil {
        fmt.Println("http  readAll body error ", err)
        return false
    }
    fmt.Println(string(bodys))
    var msg SimpleMessage
    if len(bodys) > 0 {
        err = json.Unmarshal(bodys, &msg)
        if err != nil {
            fmt.Println("http  json body error ", err)
            return false
        }
        fmt.Println(msg)
    }
    if msg.Code == "OK" {
        return true
    }
    return false
}

//setQueryStr 设置查询请求
func setQueryStr(phone, content string, id int64) string {
    var cstZone = time.FixedZone("GMT", 0)
    keyTime := time.Now().In(cstZone).Format("2006-01-02T15:04:05Z")
    singNameS := url.QueryEscape("name")
    buf := bytes.Buffer{}
    buf.WriteString("AccessKeyId=")
    buf.WriteString(ak)
    buf.WriteString(actionStr)
    buf.WriteString("&PhoneNumbers=")
    buf.WriteString(phone + singName + singNameS + singStr)
    buf.WriteString(strconv.FormatInt(id, 10) + msgTemplete + content)
    buf.WriteString("&Timestamp=" + url.QueryEscape(keyTime) + dateStr)
    signString := buf.String()
    return signString
}

2.阿里云消息接口加密sha1mac

//hmac4Go 加密
func hmac4Go(name, sk string) string {
    mac := hmac.New(sha1.New, []byte(sk))
    mac.Write([]byte(name))
    encodeString := base64.StdEncoding.EncodeToString(mac.Sum(nil))
    return encodeString
}
