[C#/Java] C#中调用Servlet示例

需求

通用消息接口使用servlet作为服务器端服务接口，第三方应用程序通过http post的方式调用servlet，实现与通用消息接口的调用连接。
参数说明如下：
msgTitle:消息标题，描述发送消息的标题
serviceId:服务编号，消息的服务编号
msgDesp:消息描述，消息的详细内容
msgURL:URL地址，消息中包含的 URL
上述4个参数的参数值可以为空，但参数必须提供。

调用示例

下面一段简单的html代码，描述了如何通过网页进行调用通用消息接口的模式，供参考。

<html><head><title>Sametime通用消息服务</title>

</head><body>

<formaction="http://stproxy.test.foton.com:9080/

fotonstbot/ServiceServlet" method="post">name="msgTitle" /><br />

服务编号: <input type="text" id="serviceId" name="serviceId" /><br />

消息描述:  <input type="text" id="msgDesp" name="msgDesp" /><br />

URL:   <input type="text" id="msgUrl" name="msgUrl" /><br />

系统类型:   <input type="text" id="sysType" name="sysType" /><br />

目标用户:  <input type="text" id="targetuser" name="targetuser" style="width:500px;" /><br />

<input type="submit" value="Submit" />

</form>

</body></html>

C#调用示例

/// <summary>

/// sametime

/// </summary>

/// <param name="bstrReceiver">sametime用户</param>

/// <param name="bstrTitle">标题</param>

/// <param name="lDelayTime">响应时间</param>

/// <param name="bstrMsg">内容</param>

public static void SendNotify(string bstrReceiver, string bstrTitle, int lDelayTime, string bstrMsg)

    string user="";

    try {

        String url = "http://stproxy.foton.com.cn:9081/fotonstbot/ServiceServlet";//html调用的地址

        HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url);

        if(webrequest==null)

        {

            RecorderErrorRtx(bstrReceiver,bstrTitle,bstrMsg,"服务端异常",);

            return;

        }

        webrequest.Method = "POST";

        webrequest.Timeout = lDelayTime;

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

        byte[] bufferTitile = Encoding.GetEncoding("utf-8").GetBytes(bstrTitle);

        string sbTitle = "";

        pars.Add("msgTitle", sbTitle);

        pars.Add("serviceId", "");

        pars.Add("msgDesp",  sbContent);

        pars.Add("msgUrl", "");

        pars.Add("sysType", "QCTS");

        user="uid="+bstrReceiver+",cn=users,DC=FOTON;";

        pars.Add("targetuser", user);

        string buffer="";

        //发送POST数据

        if (!(pars == null || pars.Count == ))

        {

            foreach (string key in pars.Keys)

            {

                buffer=buffer+"&"+key+"="+pars[key].ToString();

            }

            byte[] data = Encoding.UTF8.GetBytes(buffer);

            using (Stream stream = webrequest.GetRequestStream())

            {

                stream.Write(data, , data.Length);

            }

        }

        string[] values = webrequest.Headers.GetValues("Content-Type");

        WebResponse myResponse= webrequest.GetResponse();

        using(Stream resStream = myResponse.GetResponseStream())//得到回写的流

        {

            StreamReader newReader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);

            string Content = newReader.ReadToEnd();

            newReader.Close();

        }

        RecorderRtx(user,bstrTitle,bstrMsg,);

    }

    catch(Exception ex)

    {

        RecorderErrorRtx(user,bstrTitle,bstrMsg,ex.Message,);

    }

}
