RPC C++调用

Question

我还没有看到通过输入某些字符串来调用XML-RPC，并通过连接到XML在c++中获得某些字符串响应的文档。这是服务器提供的文档。我想不出该怎么做

    A client can interact with a Pandorabot by POST'ing to:

    http://www.pandorabots.com/pandora/talk-xml
    The form variables the client needs to POST are:

    botid - see H.1 above.
    input - what you want said to the bot.
    custid - an ID to track the conversation with a particular customer. This variable is optional. If you don't send a value Pandorabots will return a custid attribute value in the <result> element of the returned XML. Use this in subsequent POST's to continue a conversation.
    This will give a text/xml response. For example:

    <result status="0" botid="c49b63239e34d1d5" custid="d2228e2eee12d255">
      <input>hello</input>
      <that>Hi there!</that>
    </result>

    The <input> and <that> elements are named after the corresponding AIML elements for bot 
input and last response.
 If there is an error, status will be non-zero and there will be a human readable <message> element included describing the error. 

For example:
    <result status="1" custid="d2228e2eee12d255">
      <input>hello</input>
      <message>Missing botid</message>
    </result>

在C++中通过超文本传输协议进行通信的最简单方法是使用专门为此目的而设计的库。例如，libcurl提供了发送和接收问题中显示的那种请求和响应所需的所有工具。
