示例代码

依赖

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/sms/send"
	APPID  = "10***"
	APPKEY = "f8a5**********************778df"
)

非加密代码示例

    postdata := make(map[string]string)
	postdata["appid"] = APPID
	postdata["signature"] = APPKEY
	postdata["content"] = "【SUBMAIl】这是一条 demo 短信，感谢您使用 SUBMAIL 短信服务"
	postdata["to"] = "152********"

	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

    //所需参数

	postdata["content"] = "【SUBMAIl】这是一条 demo 短信，感谢您使用 SUBMAIL 短信服务"
	postdata["to"] = "152********"
	postdata["timestamp"] = ""
	postdata["sign_type"] = "md5"
	postdata["sign_version"] = "2"
	//获取服务器时间戳，该时间戳为 UNIX 时间戳，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)
	//签名加密
	sign := make(map[string]string)
	sign["appid"] = postdata["appid"]

	sign_list := make([]string, 0, 32)
	for _, key := range keys {
