我在使用 Android RESTful 消费者从 Web 服务获取简单输出时遇到问题。下面是我的代码和我的输出。但是,我似乎无法获得从此 Web 服务返回的值。http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit
如果有人能帮助我弄清楚为什么它在 SOAP 消息中显示,我将不胜感激
"Server was unable to process request. ---> Data at the root level is
invalid"
我的代码编译并运行良好
public class MainActivity extends Activity {
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
BufferedReader in = null;
try {
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost(
"http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit");
List<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("param1", "77"));
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters);
request.setEntity(formEntity);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
in.close();
String page = sb.toString();
// Log.i(tag, page);
System.out.println(page);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
我的输出
