java - 如何使用 android-ksoap2 构建正确的 XML 请求？

Question

我尝试从 Android 项目调用 Web 服务，但无法传递任何参数。

我需要构建这样的请求:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="www.mywebservice.com">
  <SOAP-ENV:Body>
    <ns1:MyMethodName>
      <ns1:appUser>0</ns1:appUser>
    </ns1:MyMethodName>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

但是使用 ksoap2，我得到这样的结果:

<v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
  <v:Header />
  <v:Body>
    <MyMethodName xmlns="www.mywebservice.com">
      <appUser>0</appUser>
    </MyMethodName>
  </v:Body>
</v:Envelope>

我的代码是:

SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);
request.addProperty("appUser",0);

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setAddAdornments(false);
envelope.implicitTypes = true;

envelope.setOutputSoapObject(request);

HttpTransportSE httpTransport = new HttpTransportSE(URL);
httpTransport.debug = true;

httpTransport.call(SOAP_ACTION, envelope);

尝试了很多示例，但似乎没有任何效果 - 我无法构建正确的 XML 请求。

我解决了这个问题:

1. 创建了一个新类，它扩展了 SoapSerializationEnvelope 并重写了其方法 write - 我已对其进行了修改以满足我的需要:

   public class MyNewClass extends SoapSerializationEnvelope {
   
           public MyNewClass (int version) {
               super(version);
           }
   
           @Override
           public void write(XmlSerializer writer) throws IOException {
               env = "http://schemas.xmlsoap.org/soap/envelope/";
               String tem = "www.mywebservice.com";
               writer.startDocument("UTF-8", true);
               writer.setPrefix("SOAP-ENV", env);
               writer.setPrefix("ns1", tem);
               writer.startTag(env, "Envelope");
               writer.startTag(env, "Body");
               writer.startTag(tem, "MyMethodName");
               writeBody(writer);
               writer.endTag(tem, "MyMethodName");
               writer.endTag(env, "Body");
               writer.endTag(env, "Envelope");
               writer.endDocument();
           }
       }
   

2. 不要使用SoapSerializationEnvelope:

   SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
   

我使用我新创建的类:

MyNewClass envelope = new MyNewClass (SoapEnvelope.VER11);
