配置信息

const (

非加密代码示例

    postdata := make(map[string]string)
    postdata["appid"] = APPID
    postdata["signature"] = APPKEY
    body := &bytes.Buffer{}
    writer := multipart.NewWriter(body)
    for key, val := range postdata {
        _ = writer.WriteField(key, val)
    }
    contentType := writer.FormDataContentType()
    writer.Close()
    resp, _ := http.Post(API, contentType, body)
    result, _ := ioutil.ReadAll(resp.Body)
    fmt.Println(string(result))

加密代码示例

    postdata := make(map[string]string)
    postdata["appid"] = APPID
    postdata["signature"] = ""

    postdata["sign_type"] = "md5"

    m := make(map[string]float64)
    json.Unmarshal(r, &m)
    postdata["timestamp"] = strconv.FormatFloat(m["timestamp"], 'f', -1, 64)
    //签名加密
    sign := make(map[string]string)

    sign_str := APPID + APPKEY + strings.Join(sign_list, "&") + APPID + APPKEY
    mymd5 := md5.New()
    io.WriteString(mymd5, sign_str)
