Android SOAP wsdl

Question

我正在尝试从SOAP连接到Web服务。 我用PHP开发了SOAP Web服务，并且运行良好（在Visual Studio中尝试过）。

首先，这是错误：

您可以在这里查看完整的错误： http : //pastebin.com/cRQ66vrj

这是我的Java代码：

private final String NAMESPACE = "http://10.0.0.20/soap/test_wsdl";
private final String URL = "http://10.0.0.20/info_send/encode.php?wsdl";
private final String SOAP_ACTION = "http://10.0.0.20/info_send/encode.php/select_data";
private final String METHOD_NAME = "select_data";
private String Webresponse = "";

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response;
            response = (SoapPrimitive)envelope.getResponse();
            Webresponse = response.toString();
        } catch (SoapFault e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        }

        Log.e("VALUE: ", Webresponse);

我一直在关注几个教程，但是没有一个适合我的需求。 因此，我正在尝试创建一种满足我需要的方法。 另外，我还添加了清单：

<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET"/>

我究竟做错了什么？ 另外，如果您能为我指明方向，以便我可以逐项获取上面代码中检索到的值，我将非常感谢。 就像是：

for(int i = 0; i <= variable.size; i++){
   Log.e("Value: ", variable[i].ToString())
}

谢谢。

Answer 1

从您的日志中

at android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1133)

确保您的SOAP请求在AsyncTask （或Service）中运行。

如果在主线程中运行它（也称为活动），则可能导致上述错误。

您可以在这里找到有关AsyncTask的信息

这里有一些例子

Answer 2

首先，异常清楚地告诉您代码有什么问题

Caused by: android.os.NetworkOnMainThreadException

您不能在主线程上执行长时间运行的网络操作。 至少将最后一个方法调用移至异步方法，您可以这样操作，

ExecutorService mExec = Executors.newSingleThreadExecutor();

    mExec.execute(new Runnable() {          
                @Override
                public void run() {             
                    try{
        androidHttpTransport.call(SOAP_ACTION, envelope);
                    }catch(Exception exc){
                        exc.printStackTrace();
                    }
                }
            });

我必须添加此行以使ksoap2可以与我的网络服务一起使用androidHttpTransport.setXmlVersionTag（K.STR_XML_VERSION）;

我还设置了以下SOAP信封属性

        envelope.encodingStyle = SoapEnvelope.ENV;
        envelope.setAddAdornments(false);
        envelope.implicitTypes = false;

Answer 3

使用AsyncTask进行与网络相关的操作...

下面是另一种解决方案：只需在代码中添加以下行即可。

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
