我需要在Android设备中调用soap webservice。我一直在阅读stackoverflow和其他页面上的很多文章，观看视频......但是我已经尝试了所有的东西而且我无法在我的Android设备中使它工作，我无法做到在模拟器上测试，因为我的计算机无法处理它们中的任何一个，因此我不知道错误是否在代码上或者是否是我的Android设备的问题。
布局xml只是EditText，Button和TextView。
在此链接中，您可以看到我需要发送到Web服务的请求xml（我应该使用SOAP 1.1还是SOAP 1.2？） http://www.webservicex.net/globalweather.asmx?op=GetCitiesByCountry
这是我的实际代码，我尝试了许多其他方法，但没有一个方法适合我。有帮助吗？ （url，namespace，soap_action和method_name值是okey，不是吗？）
package com.example.doazdoas.webservice_prueba;

您可以在doInBackGround中执行任何与UI相关的操作，因此请将其移至onPostExecute methnod。
因为doInBackGround不是UI线程。请仔细阅读AsyncTask文档。无论您从doInBackGround返回的数据是什么，它都会被视为onPostExecute的输入。
所以改变你的代码如下，
private class AsyncCallWS extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
Log.i(TAG, "onPreExecute");
}
@Override
protected String[] doInBackground(Void... params) {
Log.i(TAG, "doInBackground");
String[] data = sendRequest();
return data;
}
@Override
protected void onPostExecute(String[] result) {
Log.i(TAG, "onPostExecute");
if(result != null && result.length > 0){
textResult.setText( results[0]);
}
}
}
private String[] sendRequest(){
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//SoapObject
request.addProperty("@CountryName", "SPAIN");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
androidHttpTransport = new HttpTransportSE(URL);
try
{
androidHttpTransport.call(SOAP_ACTION, envelope);
resultsRequestSOAP = envelope.getResponse();
String[] results = (String[]) resultsRequestSOAP;
}
catch (Exception aE)
{
aE.printStackTrace ();
}
}

您是否考虑过不使用图书馆来提出肥皂请求？我之前遇到了同样的问题，这让我发现库会让你的工作更难，特别是在改变请求的结构时。这是您在不使用库的情况下发出soap请求的方法： 首先，您需要知道如何使用SOAP Ui这是一个Windows应用程序。您可以在此处导入您的wsdl文件，如果它的语法正确，那么您将看到一个显示Web服务请求正文的屏幕。您可以输入测试值，您将获得响应结构。此链接将指导您如何使用soap ui https://www.soapui.org/soap-and-wsdl/working-with-wsdls.html
现在开始使用android代码：
我们将创建一个名为runTask的类，它扩展异步任务并使用http发送请求主体并获取请求响应：
private class runTask extends AsyncTask<String, String, String> {
private String response;
String string = "your string parameter"
String SOAP_ACTION = "your soap action here";
String stringUrl = "http://your_url_here";
//if you experience a problem with url remove the '?wsdl' ending
@Override
protected String doInBackground(String... params) {
try {
//paste your request structure here as the String body(copy it exactly as it is in soap ui)
//assuming that this is your request body
String body = "<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>"+
"<GetCitiesByCountryResponse xmlns="http://www.webserviceX.NET">"+
"<GetCitiesByCountryResult>"+string+"</GetCitiesByCountryResult>"+
"</GetCitiesByCountryResponse>"+
"</soap:Body>"+
"</soap:Envelope>";
try {
URL url = new URL(stringUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setDefaultUseCaches(false);
conn.setRequestProperty("Accept", "text/xml");
conn.setRequestProperty("SOAPAction", SOAP_ACTION);
//push the request to the server address
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(body);
wr.flush();
//get the server response
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder builder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
builder.append(line);
response = builder.toString();//this is the response, parse it in onPostExecute
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
reader.close();
} catch (Exception e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
return response;
}
/**
* @see AsyncTask#onPostExecute(Object)
*/
@Override
protected void onPostExecute(String result) {
try {
Toast.makeText(this,"Response "+ result,Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}
现在只需执行课程并观察神奇的事情：
runTask runner = new runTask();
runner.execute();
您可以使用DOM或SAX解析器解析响应以获取所需的值。 请随时要求进一步澄清。
