原作者: [db:作者] 来自: [db:来源] 收藏 邀请

阿里大鱼还未提供 .net core 版SDK,但提供了相关API,下面是.net core版实现,只是简单发送短信功能:

        req.Method = "POST";
        req.Accept = "text/xml,text/javascript";
        req.ContinueTimeout = 60000;

        byte[] postData = encoding.GetBytes(data);
        Stream reqStream = req.GetRequestStreamAsync().Result;
        reqStream.Write(postData, 0, postData.Length);
        reqStream.Dispose();

        var rsp = (HttpWebResponse)req.GetResponseAsync().Result;
        var result = GetResponseAsString(rsp, encoding);
        return result;
      }
      catch (Exception ex)
      {
        throw;
      }
    }

    public static T Post<T>(string url, string data, Encoding encoding)
    {
      try

      }
      catch (Exception ex)
      {

      }
    }

    public static string BuildQuery(IDictionary<string, string> parameters)

      {
        string name = kv.Key;
        string value = kv.Value;
        // 忽略参数名或参数值为空的参数
        if (!string.IsNullOrEmpty(name) && !string.IsNullOrEmpty(value))
        {
          if (hasParam)
          {
            query.Append("&");
          }

          query.Append(name);
          query.Append("=");
          query.Append(WebUtility.UrlEncode(value));
          hasParam = true;
        }
      }

      return query.ToString();
    }

    public static string GetResponseAsString(HttpWebResponse rsp, Encoding encoding)
    {

        reader = new StreamReader(stream, encoding);
        return reader.ReadToEnd();
      }
      finally

        if (reader != null) reader.Dispose();
        if (stream != null) stream.Dispose();
        if (rsp != null) rsp.Dispose();
      }
    }

    public static string GetAlidayuSign(IDictionary<string, string> parameters, string secret, string signMethod)

      //把所有参数名和参数值串在一起
      StringBuilder query = new StringBuilder();
      if (Constants.SIGN_METHOD_MD5.Equals(signMethod))
      {
        query.Append(secret);
      }
      foreach (KeyValuePair<string, string> kv in sortedParams)

        }
      }

      //使用MD5/HMAC加密
      if (Constants.SIGN_METHOD_HMAC.Equals(signMethod))
      {
        return Hmac(query.ToString(), secret);
      }
      else
      {
        query.Append(secret);
        return Md5(query.ToString());
      }
    }

    public static string Hmac(string value, string key)
    {
      byte[] bytes;
      using (var hmac = new HMACMD5(Encoding.UTF8.GetBytes(key)))
      {
        bytes = hmac.ComputeHash(Encoding.UTF8.GetBytes(value));
      }
      StringBuilder result = new StringBuilder();
      foreach (byte t in bytes)
      {
        result.Append(t.ToString("X2"));

      }
      return result.ToString();
    }

    public static string Md5(string value)
    {
      byte[] bytes;
      using (var md5 = MD5.Create())
      {
        bytes = md5.ComputeHash(Encoding.UTF8.GetBytes(value));
      }
      var result = new StringBuilder();
      foreach (byte t in bytes)
      {
        result.Append(t.ToString("X2"));
      }
      return result.ToString();
    }

    public static SmsResultAli SendSms(string url, string appKey, string appSecret, DateTime timestamp, Dictionary<string, string> parsms)
    {
      var txtParams = new SortedDictionary<string, string>();
      txtParams.Add(Constants.METHOD, "alibaba.aliqin.fc.sms.num.send");
      txtParams.Add(Constants.VERSION, "2.0");
      txtParams.Add(Constants.SIGN_METHOD, Constants.SIGN_METHOD_HMAC);
      txtParams.Add(Constants.APP_KEY, appKey);
      txtParams.Add(Constants.FORMAT, "json");

      txtParams.Add(Constants.SMS_TYPE, "normal");
      foreach (var item in parsms)
      {
        txtParams.Add(item.Key,item.Value);
      }

      txtParams.Add(Constants.SIGN, GetAlidayuSign(txtParams, appSecret, Constants.SIGN_METHOD_HMAC));
      var result = Post<SmsResultAli>(url, BuildQuery(txtParams), Encoding.UTF8);

      return result;
    }

  }

  public class SmsResultAli
  {
    public SmsResponseALi Alibaba_Aliqin_Fc_Sms_Num_Send_Response { get; set; }
  }

  public class SmsResponseALi
  {
    public string Request_Id { get; set; }
    public SmsResponseResultAli Result { get; set; }
  }

  public class SmsResponseResultAli
  {
    public string Err_Code { get; set; }

    public string Model { get; set; }

    public bool Success { get; set; }
  }
}

发送短信时:          

var parms = new Dictionary<string, string>();
  parms.Add(Constants.EXTEND, "123456");
  parms.Add(Constants.REC_NUM, "138********");
  parms.Add(Constants.SMS_FREE_SIGN_NAME, "阿里大鱼");
  parms.Add(Constants.SMS_PARAM, "{\"code\":\"1234\",\"product\":\"阿里大鱼\"}");
  parms.Add(Constants.SMS_TEMPLATE_CODE, "SMS_10000000");

var req = SmsHelper.SendSms("http://gw.api.taobao.com/router/rest", "appKey", "appSecret", DateTime.Now, parms);

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持极客世界。
