我在寻找关于如何使用Android调用标准SOAP/WSDL web服务的好信息时遇到了很多麻烦。我所能找到的只是一些非常复杂的文档和对“kSoap2”的引用,以及一些关于用SAX手动解析它的内容。好吧,这很好,但现在是2008年,所以我认为应该有一些调用标准web服务的好库。

web服务基本上就是在NetBeans中创建的。我希望有IDE支持来生成管道类。我只是需要最简单/最优雅的方法来从基于android的电话联系基于WSDL的web服务。

的确,由于开销过大,SOAP并不是与移动设备进行数据交换的最佳选择。但是,您可能会发现自己处于无法控制服务器输出格式的情况。

所以,如果你必须坚持使用SOAP,这里有一个为Android打补丁的kSOAP2库: http://code.google.com/p/ksoap2-android/

Few months ago I was working with jax-ws web service in j2ee application, There we were using CXF wsdl2java to generate WS client stub from the WSDL file and with those client stubs we consumed the web services. Few weeks ago, when I was trying to consume the web service in the same way in android platform I couldn't, because the android jar has not all the "jax-ws" supporting classes in it. That time I didn't find any such tool ( if I wasn't failed to google efficiently) to meet my requirement --

从WSDL获取客户端存根。 并使用一些参数调用服务(java业务请求 对象)。 获取响应业务对象。

因此,我开发了自己的Android SOAP客户端生成工具。你需要遵循以下步骤:

从WSDL获取WS客户端存根,将其放入您的项目中。 例如,对于某些服务“ComplexOperationService”,实例化 Service,获取端点端口并调用服务方法,并从Web服务获取响应:

eg:

ComplexOperationService service = new ComplexOperationService( );
ComplexOperation port= service.getComplexOperationPort();    
SomeComplexRequest request = --Get some complex request----;    
SomeComplexResp resp = port.operate( request  );

您不需要关心服务类/请求/响应类或任何其他类以及方法,因为您知道它们都是从WSDL生成的。 当然,您不需要知道soap动作/信封/名称空间等等。就像我们开发人员一直做的那样调用这个方法。

默认情况下,Android SDK中包含defaulthttpclient。这将使您连接到WSDL。

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://www.example.com/" + URL);
HttpResponse response = httpClient.execute(httpGet, localContext);

如果你有关于在android中调用Web服务的问题 您可以使用下面的代码来调用web服务并获得响应。确保您的web服务以数据表格式返回响应..如果您使用SQL Server数据库中的数据,此代码将帮助您。如果你使用MYSQL,你需要改变一件事,只需替换单词NewDataSet从句子obj2=(SoapObject) obj1.getProperty("NewDataSet");由DocumentElement

void callWebService(){ 

private static final String NAMESPACE = "http://tempuri.org/"; // for wsdl it may be package name i.e http://package_name
private static final String URL = "http://localhost/sample/services/MyService?wsdl";
// you can use IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = "urn:" + METHOD_NAME;

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    request.addProperty("parm_name", prm_value);// Parameter for Method
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;// **If your Webservice in .net otherwise remove it**
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);// call the eb service
                                                                                                         // Method
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Next task is to get Response and format that response
    SoapObject obj, obj1, obj2, obj3;
    obj = (SoapObject) envelope.getResponse();
    obj1 = (SoapObject) obj.getProperty("diffgram");
    obj2 = (SoapObject) obj1.getProperty("NewDataSet");

    for (int i = 0; i < obj2.getPropertyCount(); i++) { 
// the method getPropertyCount() and  return the number of rows
            obj3 = (SoapObject) obj2.getProperty(i);
            obj3.getProperty(0).toString();// value of column 1
            obj3.getProperty(1).toString();// value of column 2
            // like that you will get value from each column
        }
    }

如果你有任何问题,你可以写信给我。

我相信您可以用Axis创建一个小型SOAP客户机。轴安装说明。

我已经为Android平台创建了一个新的SOAP客户机。它使用一个JAX-WS生成的接口,但到目前为止它只是一个概念验证。

如果你感兴趣,请尝试这个例子和/或在AndroidSOAP上观看源代码。
