其实这个也不是很难，掉官方的sdk即可实现，但是苦逼的是我的项目是.net core ,官方的sdk有好多地方不支持，所以值得重写sdk
先把自己走过的坑补充一下：
出现的问题1：
l You must add a reference to assembly “mscorlib,Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089”
解决办法：使用NuGet包管理安装：
Install-Package Microsoft.NETCore.Portable.Compatibility -Version 1.0.1
出现的问题2
l 对象引用对于非静态的字段，方法或属性
解决办法：
把出现问题的方法改成static即可
出现的问题3：
l 命名空间System.Net中不存在类型或者命名空间ServicePointManager
自己创建一个ServicePointManager，不要质疑，真的是照着原来的sdk创建了一个一模一样的方法就可以用了
出现的问题4：
WebHeaderCollection中的Headers未包含Add方法
这个其实是因为后来的WebHeaderCollection中的header可以这样添加：
类似的问题还有：
进行请求：
// 开始请求 using (Stream postStream = request.GetRequestStream()) { postStream.Write(byteData, 0, byteData.Length); }在这里要换成：
var reqStreamAsync = request.GetRequestStreamAsync(); using(Stream reqStream = reqStreamAsync.Result) { reqStream.Write(byteData, 0, byteData.Length); reqStream.Dispose(); }获取请求
// 获取请求 using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) {换成：
var reqAsync = request.GetResponseAsync(); using (HttpWebResponse response = reqAsync.Result as HttpWebResponse) {下面的还有这种情况就不一一列举了，直接上sdk代码，需要的时候可以拿出来看看。

public static void SendSmSAsync() { string ret = null; CCPRestSDK.CCPRestSDK api = new CCPRestSDK.CCPRestSDK(); bool isInit = api.init("app.cloopen.com", "8883"); api.setAccount("8aaf07085e2d97fd015e454b503c07ab", "f7fac0ec2ae7468b8770a6e7d1db63b8"); api.setAppId("8aaf07085e2d97fd015e454b51c507b1"); try { if (isInit) { string[] data = { "7654", "10" };//验证码，时间 Dictionary<string, object> retData = api.SendTemplateSMS("13821875330", "1", data); ret = getDictionaryData(retData); string statusCode = retData["statusCode"].ToString(); string statusMsg = retData["statusMsg"].ToString(); Console.WriteLine(statusCode + "==" + statusMsg + "<br><br><br><br>"); } else { ret = "初始化失败"; } } catch (Exception exc) { ret = exc.Message; } finally { Console.Write(ret); } } public static string getDictionaryData(Dictionary<string, object> data) { string ret = null; foreach (KeyValuePair<string, object> item in data) { if (item.Value != null && item.Value.GetType() == typeof(Dictionary<string, object>)) { ret += item.Key.ToString() + "={"; ret += getDictionaryData((Dictionary<string, object>)item.Value); ret += "};"; } else { ret += item.Key.ToString() + "=" + (item.Value == null ? "null" : item.Value.ToString()) + ";"; } } return ret; }最后在主函数中直接调用sendSms即可
