4、  注意事项

1）、查看WSDL内容，分析出WS的服务名（函数名）、参数列表。

2）、出现“webservice 服务器未能识别 HTTP 头 SOAPAction 的值…”问题，一般是由于命名空间不对，默认的命名空间是“http://tempuri.org/”。

3）、如果想分析详细的错误信息，可以查看          ISoapReaderPtr Reader; (const char*)Reader->Body->xml的内容，得到详细的信息，具体操作请参考上面的代码。

4）、(const char*)Reader->RpcResult->text 表示接受返回信息；(const char*)Reader->RpcResult->xml，表示接受得到信息，以XML格式存储。可以通过CMarkup类得到每个项的内容，可以映射到一个对应的结构体，从而得到所有返回的信息。
