融云发送手机短信验证短信（.net版本）

　　首先本次需求是在MVC5中进行的，通过收费的融云服务来验证手机号码，而且本次的项目也是前后台分离，所以添加了WEBAPI2，那么先添加WEBAPI的接口

using System;

using System.Web.Http;

using System.Net.Http;

using System.Web.Script.Serialization;

using System.Text;

using System.Web;

namespace BlackNails.Controllers

{

    public abstract class WebAPI2BaseController : ApiController

    {

        public HttpContext context = HttpContext.Current;

        public static HttpResponseMessage toJson(Object obj)

        {

            String str;

            if (obj is String || obj is Char)

            {

                str = obj.ToString();

            }

            else

            {

                JavaScriptSerializer serializer = new JavaScriptSerializer();

                str = serializer.Serialize(obj);

            }

            HttpResponseMessage result = new HttpResponseMessage { Content = new StringContent(str, Encoding.GetEncoding("UTF-8"), "application/json") };

            return result;

        }

        public string Options()

        {

            return null; // HTTP 200 response with empty body

        }

    }

}

然后添加一个UserController接口文档

using BlackNails.CommonClass;

using BlackNails.Controllers;

using BlackNails.DAL;

using System;

using System.IO;

using System.Net;

using System.Net.Http;

using System.Text;

using System.Web.Http;

using System.Web.Script.Serialization;

namespace BlackNails.WebAPI

{

    public class UserController : WebAPI2BaseController

    {

        [HttpGet]

        public HttpResponseMessage sendCode(string mobile)

        {

            var response = new Response();

            Random r = new Random();

            int i = r.Next(, );

            string Random = i.ToString();

            TimeSpan ts = DateTime.Now - DateTime.Parse("1970-1-1");

            string Timestamp = Convert.ToInt32(ts.TotalSeconds).ToString();

            //以字节方式存储

            byte[] data = Encoding.Default.GetBytes(Constant.APP_SECRET + Random + Timestamp);

            System.Security.Cryptography.SHA1 sha1 = new System.Security.Cryptography.SHA1CryptoServiceProvider();

            //得到哈希值

            byte[] result = sha1.ComputeHash(data);

            //转换成为字符串的显示

            string Signature = BitConverter.ToString(result).Replace("-", "");

            WebRequest request = WebRequest.Create("http://api.sms.ronghub.com/sendCode.json");

            request.Method = "POST";

            string postData = "mobile=" + mobile + "&templateId=" + Constant.TEMPLATE_REGISTER + "&region=86";

            byte[] byteArray = Encoding.UTF8.GetBytes(postData);

            request.ContentType = "application/x-www-form-urlencoded";

            request.ContentLength = byteArray.Length;

            request.Headers.Add("App-Key", Constant.APP_KEY);

            request.Headers.Add("Nonce", Random);

            request.Headers.Add("Timestamp", Timestamp);

            request.Headers.Add("Signature", Signature);

            Stream dataStream = request.GetRequestStream();

            dataStream.Write(byteArray, , byteArray.Length);

            dataStream.Close();

            WebResponse resp = request.GetResponse();

            dataStream = resp.GetResponseStream();

            StreamReader reader = new StreamReader(dataStream);

            string responseFromServer = reader.ReadToEnd();

            JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();

            ReturnJson _ReturnJson = jsonSerializer.Deserialize<ReturnJson>(responseFromServer);

            var code = _ReturnJson.code;

            var sessionId = _ReturnJson.sessionId;

            if(code == )

            {

                response.Code = ;

                response.Message = "发送验证码成功！";

                context.Cache.Insert(mobile, sessionId);

            } else

            {

                response.Code = ;

                response.Message = "发送验证码失败！";

                context.Cache.Insert(mobile, "");

            }

            reader.Close();

            dataStream.Close();

            resp.Close();

            response.Data = null;

            return toJson(response);

        }

        [HttpGet]

        public HttpResponseMessage verifyCode(string mobile, string code)

        {

            var response = new Response();

            Random r = new Random();

            int i = r.Next(, );

            string Random = i.ToString();

            TimeSpan ts = DateTime.Now - DateTime.Parse("1970-1-1");

            string Timestamp = Convert.ToInt32(ts.TotalSeconds).ToString();

            //以字节方式存储

            byte[] data = Encoding.Default.GetBytes(Constant.APP_SECRET + Random + Timestamp);

            System.Security.Cryptography.SHA1 sha1 = new System.Security.Cryptography.SHA1CryptoServiceProvider();

            //得到哈希值

            byte[] result = sha1.ComputeHash(data);

            //转换成为字符串的显示

            string Signature = BitConverter.ToString(result).Replace("-", "");

            WebRequest request = WebRequest.Create("http://api.sms.ronghub.com/verifyCode.json");

            request.Method = "POST";

            string postData = "sessionId="+ context.Cache[mobile] +"&code=" + code;
