功能实现

融合云通信服务平台,为企业提供全方位通信服务,发送手机短信是其一项核心功能,本文将讲述如何使用融合云服务API为终端手机用户发送短信信息,并使用 C# 进行实现。

范例运行环境

操作系统: Windows Server 2019 DataCenter

.net版本: .netFramework4.7.2 或以上

开发工具:VS2019  C#

实现范例

类设计

设计UTC(融合通信)类,子类SMS类实现发送短信功能,SMS类设计见下表:

序号成员类型名称类型说明
1属性ErrorMessagestring此值代表调用API时发生的任何错误信息
2属性ResultJsonstring返回调用API成功后返回的结果(并不代表一定发送成功)
3属性errcodestring成功调用API后返回的错误码:0代表发送成功,其它值请参照 errmsg 值提示
4属性errmsgstring请参照 errcode属性的解释
5属性cTypestring默认值为xml(小写值),还可选择 json(小写值),这是云平台提供的两种 POST 消息体的类型
6属性signstring申请云API开发者,被授权提供的签名,如【XX公司】
7属性uidstring申请云API开发者,被授权提供的用户名
8属性pwdstring申请云API开发者,被授权提供的密码
9属性desttypestring目标手机用户运营商类型:1 移动,2 联通,3电信 ,默认为 0 (通用)
10属性sendUrlstring申请云API开发者,被授权提供的可调用API地址,一般会有两个地址:
POST XML 消息体的请调用例如:
http://api.uctyun.cn:0000/adc_posthandler_new
POST JSON 消息体的请调用例如:
http://api.uctyun.cn:0000/adc_posthandler_json
11属性postInfostring这是一个调试信息,返回生成的 POST 消息体信息
12方法sendvoidsend方法有两个参数:
1:string phoneNumber (手机号)
2:string msgContent (要发送的消息)
本方法无返回类型,返回值均返写到 ErrorMessage / ResultJson / errcode / errmsg / postInfo 属性值上

类代码实现

实现代码如下:

public class UTC
{
            public class SMS
            {
                public string ErrorMessage = "";
                public string ResultJson = "";
                public string errcode = "";
                public string errmsg = "";
                public string cType = "xml";
                public string sign { get; set; }
                public string uid { get; set; }
                public string pwd { get; set; }
                public string desttype { get; set; }
                public string sendUrl { get; set; }
                public string postInfo = "";
                public SMS() {
                    desttype = "0";
 
                }
                public void send(string phoneNumber, string msgContent) {
                    byte[] bytes = System.Text.Encoding.UTF8.GetBytes(msgContent + sign);

                    headers[2] = "Action:\"submitreq\"";

                                    "\"desttype\":\"" + desttype + "\"}]}";
                    if (cType == "xml")

                        string xmlData = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Body>" +
                        "<user>" + uid + "</user><password>" + pwd + "</password>" +

                    errmsg = "";
                    string rs=GetResponseResult(sendUrl, Encoding.UTF8, "POST", postData, headers);
                    ErrorMessage = ws.ErrorMessage;
                    ResultJson = rs;
                    if (ErrorMessage == "" && ResultJson != "")

                            if (rv_xml.Length>1)
                            {
                                errmsg = rv_xml[1];
                            }
                        }

                                Newtonsoft.Json.Linq.JObject jsonObj = Newtonsoft.Json.Linq.JObject.Parse(rs);
                                string[] rv = jsonObj["result"].ToString().Split(':');
                                errcode = rv[0];

                            catch (Exception e)
                            {
                                ErrorMessage += "\r\n" + e.Message;
                                ResultJson = rs;
                            }
                        }
                    }
 
                }
        public string GetBetweenStr(string wholestr,string beginstr,string endstr)

                }
            }

		    }
 
       }
}

调用范例

示例代码如下:

UTC.SMS utcsms = new UTC.SMS();
utcsms.cType = "xml";   //设置为 POST XML 消息体类型
utcsms.uid = "888888";              
utcsms.pwd = "TJ999999";
utcsms.sign = "【XX公司】";
utcsms.sendUrl = "http://api.uctyun.cn:0000/adc_posthandler_new";
//utcsms.sendUrl = "http://api.uctyun.cn:0000/adc_posthandler_json";  //如果是JSON请访问这个类型的API 地址
 
//发送短信,提供手机号和短信息内容
utcsms.send("13899999999", "融合通信提醒您,您正在执行登录操作,验证码:12345678");
 
string debug = string.Format("API:errcode:{4}\r\nerrmsg:{5}\r\n{3}\r\nErrMessage:{0}\r\nResultJson:{1}\r\nPostInfo:{2}", utcsms.ErrorMessage, utcsms.ResultJson, utcsms.postInfo, utcsms.sendUrl,utcsms.errcode,utcsms.errmsg);

总结

GetResponseResult 方法本次得到了更新,主要包括消息头的 Connection 名称,在 C#中使用 request.KeepAlive= Value == "close"?false : true; 的写法来实现。更新后的代码如下:

        public string GetResponseResult(string url, System.Text.Encoding encoding, string method, string postData,string[] headers,string ContentType= "application/x-www-form-urlencoded",bool secValid=true)
        {
            method = method.ToUpper();
            if (secValid == false)
            {
                ServicePointManager.ServerCertificateValidationCallback = validSecurity;
            }
            System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls | System.Net.SecurityProtocolType.Tls11 | System.Net.SecurityProtocolType.Tls12;
            
            if (method == "GET")
            {
                try
                {
                    WebRequest request2 = WebRequest.Create(@url);
                    request2.Method = method;
                    WebResponse response2 = request2.GetResponse();
                    Stream stream = response2.GetResponseStream();
                    StreamReader reader = new StreamReader(stream, encoding);
                    string content = reader.ReadToEnd();
                    return content;
                }
                catch (Exception ex)
                {
                    ErrorMessage = ex.Message;
                    return "";
                }
 
            }
            Stream outstream = null;
            Stream instream = null;
            StreamReader sr = null;
            HttpWebResponse response = null;
            HttpWebRequest request = null;
            byte[] data = encoding.GetBytes(postData);
            // 准备请求...
            try
            {
                // 设置参数
                request = WebRequest.Create(url) as HttpWebRequest;
                CookieContainer cookieContainer = new CookieContainer();
                request.CookieContainer = cookieContainer;
                request.AllowAutoRedirect = true;
                request.Method = method;
                request.Timeout = 1000000;
                if (headers != null)
                {
                    for(int i = 0; i < headers.GetLength(0); i++)
                    {
                        if (headers[i].Split(':').Length <2)
                        {

                            if (headers[i].Split(':')[0] == "Host") {
                                request.Host = headers[i].Split(':')[1];
                                continue;

                                continue;
                            }
 
                        }
                        request.Headers.Add(headers[i]);
                    }

                outstream = request.GetRequestStream();
                outstream.Write(data, 0, data.Length);
                outstream.Close();
                //发送请求并获取相应回应数据
                response = request.GetResponse() as HttpWebResponse;

                //返回结果网页(html)代码
                string content = sr.ReadToEnd();
                sr.Close();
                sr.Dispose();
                
                return content;
            }

            }
        }//get response result
