示例代碼

依賴

import (
    "bytes"
    "crypto/md5"
    "encoding/hex"
    "encoding/json"
    "fmt"
    "io"
    "io/ioutil"
    "net/http"
    "sort"
    "strconv"
    "strings"

    "mime/multipart"
)

配置信息

const (
    API    = "https://api-v4.mysubmail.com/balance/voice"
    APPID  = "10***"
    APPKEY = "f8a5**********************778df"
)

非加密代碼示例

    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))

加密代碼示例

    //所需參數(shù)
    postdata := make(map[string]string)
    postdata["appid"] = APPID
    postdata["signature"] = ""
    postdata["timestamp"] = ""
    postdata["sign_type"] = "md5"
    //獲取服務(wù)器時(shí)間戳，該時(shí)間戳為 UNIX 時(shí)間戳，也可以自己生成
    q, _ := http.Get("https://api-v4.mysubmail.com/service/timestamp")
    r, _ := ioutil.ReadAll(q.Body)
    m := make(map[string]float64)
    json.Unmarshal(r, &m)
    postdata["timestamp"] = strconv.FormatFloat(m["timestamp"], 'f', -1, 64)
    //簽名加密
    sign := make(map[string]string)
    sign["appid"] = postdata["appid"]
    sign["timestamp"] = postdata["timestamp"]
    sign["sign_type"] = postdata["sign_type"]
    keys := make([]string, 0, 32)
    for key, _ := range sign {
        keys = append(keys, key)
    }
    sort.Strings(keys)
    sign_list := make([]string, 0, 32)
    for _, key := range keys {
        sign_list = append(sign_list, key+"="+sign[key])
    }
    sign_str := APPID + APPKEY + strings.Join(sign_list, "&") + APPID + APPKEY
    mymd5 := md5.New()
    io.WriteString(mymd5, sign_str)
    postdata["signature"] = hex.EncodeToString(mymd5.Sum(nil))

    body := &bytes.Buffer{}
