任何人都可以告诉我哪里出错了/而是提供一个有效的例子......？
答案 0 :(得分：0)
很高兴你问这个问题，当我开始使用soap webservice时，我遇到了同样的问题。这里的关键是避免使用soap库，并使用java提供的类来发出请求并解析它，即http，DOM解析器或SAX解析器。这是您在不使用ksoap或任何其他库的情况下提出请求的方式。
现在开始使用androiod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.
String body = "<soapenv:Envelope xmlns:soapenv=\"http://someurl\" "+
"xmlns:soap=\"someurl\" "+
"xmlns:gen=\"http://someurl\"> "+
"<soapenv:Header> "+
"<auth:EventID xmlns:auth='http://someurl'>3000</auth:EventID> "+
"</soapenv:Header> "+
"<soapenv:Body> "+
"<gen:getGenericResult> "+
"<Request> "+
"<dataItem> "+
"<name>Username</name> "+
"<type>String</type> "+
"<value>usernamehere</value> "+
"</dataItem> "+
"<dataItem> "+
"<name>Password</name> "+
"<type>String</type> "+
"<value>passwordhere</value> "+
"</dataItem> "+
"</Request> "+
"</gen:getGenericResult> "+
"</soapenv:Body> "+
"</soapenv: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);
//you can pass all your request parameters here usong .setRequestProperty() method
//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();
//Go ahead and parse the response now
} catch (Exception e) {
e.printStackTrace();
}
}
现在在onCreate中，继续使用以下代码执行此类
runTask task = new runTask();
task.execute();
如果网址和请求正文被正确输入，您将在onPostExecute中获得响应，格式化并从此处解析。 使用这种无库文件方式的主要优点是它非常灵活，与只使用提供的请求格式的库相比，您可以以Web服务所需的任何方式格式化请求。该解决方案可以在我的代码中无缝运行，随时可以要求进一步澄清。
