带有附加 XML 标记的 SOAP 消息错误

Question

NSString *urlString = @"http://172.29.165.219:8090/abc/services/Abc";
NSString *soapMessage = [NSString stringWithFormat:
                         @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                         "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                         "<soap:Body>\n"
                         "<getUserInfo>\n"
                         "<email>%@</email>\n"
                         "<pwd>%@</pwd>\n"
                         "</getUserInfo>\n"
                         "</soap:Body>\n"
                         "</soap:Envelope>\n", @"[email protected]",@"UGFzc0AxMjM="//,@"50006F0063006B0065007400500043000000-444556494345454D00",@"PocketPC"
                         ];
NSMutableURLRequest *loginRequest = [RequestGenerator -generateSOAPRequestWithURLString:urlString soapMessage:soapMessage contentType:@"text/xml; charset=utf-8" action:@"getUserInfo"];
WebServiceHandler *connection = [[WebServiceHandler alloc]init];

对于上面的代码，它工作正常，但是当我将附加标签作为父标签添加到 id 和密码时，

NSString *urlString = @"http://172.29.165.219:8090/abc/services/Abc";
NSString *soapMessage = [NSString stringWithFormat:
                         @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                         "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
                         "<soap:Body>\n"
                         "<getUserInfo>\n"
                         **"<ABC>\n"**
                                                     "<email>%@</email>\n"
                         "<pwd>%@</pwd>\n"
                                                     **"</ABC>\n"**
                         "</getUserInfo>\n"
                         "</soap:Body>\n"
                         "</soap:Envelope>\n", @"[email protected]",@"UGFzc0AxMjM="//,@"50006F0063006B0065007400500043000000-444556494345454D00",@"PocketPC"
                         ];
NSMutableURLRequest *loginRequest = [RequestGenerator generateSOAPRequestWithURLString:urlString soapMessage:soapMessage contentType:@"text/xml; charset=utf-8" action:@"getUserInfo"];
WebServiceHandler *connection = [[WebServiceHandler alloc]init];

它显示异常并收到此错误：

org.xml.sax.SAXException：SimpleDeserializer 在尝试反序列化的过程中遇到了意外的子元素。

它甚至不允许我访问服务器。

在第二个肥皂消息中，您正在为您的信息发送一个额外的父标签，您的服务器可能无法识别该父标签。如果这个标签是可选的，那么应该没有问题，但如果它是不需要的，那么你不应该使用它。以下是 W3.org 的摘录（http://www.w3.org/TR/2000/NOTE-SOAP-20000508/）.... 讲述了肥皂请求的接收和处理。

A SOAP application receiving a SOAP message MUST process that message by performing 
    the following actions in the order listed below:

         1. Identify all parts of the SOAP message intended for that application 
         2. Verify that all mandatory parts identified in step 1 are supported by
 the  application for this message (see section 4.2.3) and process them accordingly.
 If this is   not the case then discard the message .
 The processor MAY ignore optional parts identified in step 1 without affecting the outcome of the processing.
        3. If the SOAP application is not the ultimate destination of the message then
     remove all parts identified in step 1 before forwarding the message.


  Processing a message or a part of a message requires that the SOAP processor 
  understands, among other things, the exchange pattern being used (one way, 
  request/response, multicast, etc.), the role of the recipient in that pattern, the 
  employment (if any) of RPC mechanisms such as the one documented in section 7, the 
  representation or encoding of data, as well as other semantics necessary for correct 
  processing
