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>
