android - 在 Android 中调用 .NET Web 服务

Question

我的 .NET Web 服务返回一个 XML。当我在 Android 中使用 ksoap2 调用 Web 服务时，我遇到了这个问题。请帮忙。

        getMenuInflater().inflate(R.menu.activity_main, menu);

}

这是示例响应 xml：

<?xml version="1.0" encoding="utf-8"?>

我解决它。我添加了这段代码。它正在工作。

我的代码

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    init();
}
private void init()
{
    //your webservice envelope
    String envelope="<?xml version=\"1.0\" encoding=\"utf-8\"?><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/\"><soap:Body><GetContentTreeBySections xmlns=\"http://tempuri.org/\"><SectionsInclude>%s</SectionsInclude><DocumentCount>%s</DocumentCount><SortBy>%s</SortBy><SortOrder>%s</SortOrder><UserName>%s</UserName><Pass>%s</Pass></GetContentTreeBySections></soap:Body></soap:Envelope>";

    String myEnvelope = String.format(envelope, "myParam1 value", "myParam2 value","myParam3 value","myParam4 value");
    String url = "http://www.mywebserice.com/XMLGenerator/GenerateXML.asmx";
    String soapAction = "http://tempuri.org/GetContentTreeBySections"; 
    String response = CallWebService(url, soapAction, myEnvelope);
    //Log.v("response", response);
    Toast.makeText(getApplicationContext(), "this"+response,Toast.LENGTH_LONG).show();
    String xml=response;    
}

@Override
public boolean onCreateOptionsMenu(Menu menu) 
{
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
String CallWebService(String url,String soapAction,String envelope) 
{

      final DefaultHttpClient httpClient=new DefaultHttpClient();
      // request parameters
      HttpParams params = httpClient.getParams();
         HttpConnectionParams.setConnectionTimeout(params, 10000);
         HttpConnectionParams.setSoTimeout(params, 15000);
         // set parameter
      HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);

      // POST the envelope
      HttpPost httppost = new HttpPost(url);
      // add headers
         httppost.setHeader("soapaction", soapAction);
         httppost.setHeader("Content-Type", "text/xml; charset=utf-8");
         String responseString="";

         try 
         {
                // the entity holds the request
                HttpEntity entity = new StringEntity(envelope);
                httppost.setEntity(entity);

                // Response handler
                ResponseHandler<String> rh=new ResponseHandler<String>() {
        // invoked when client receives response
        public String handleResponse(HttpResponse response)
          throws ClientProtocolException, IOException {

         // get response entity
         HttpEntity entity = response.getEntity();

         // read the response as byte array
               StringBuffer out = new StringBuffer();
               byte[] b = EntityUtils.toByteArray(entity);

               // write the response byte array to a string buffer
               out.append(new String(b, 0, b.length));
               return out.toString();
        }
       };

       responseString=httpClient.execute(httppost, rh); 

      }
         catch (Exception e) {
          Log.v("exception", e.toString());
      }

         // close the connection
      httpClient.getConnectionManager().shutdown();
      return responseString;
}

与其使用 ksoap，不如尝试使用开源的 ice-soap 库。它比 ksoap 好得多，并提供了高效的库来使用注释发送请求和解析响应....

首先，永远不要在主线程中使用网络操作尝试始终在非主线程中插入网络操作，如 AsyncTask 或任何其他工作线程。其次使用以下代码获取结果：

 String message="";
    SoapObject result = (SoapObject)envelope.bodyIn;
    if(result != null)
       {
          message=result.getProperty(0).toString();
       }

并更改以下代码

Request.addProperty("DocumentCount",10);

成为

Request.addProperty("DocumentCount","10");
