我遇到了使用Android RESTful使用者從Web服務獲取簡單輸出的問題。以下是我的代碼和我的輸出。但是,我似乎無法獲得從此Web服務返回的值。 http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheitAndroid Web服務使用Rest - SOAP消息中的錯誤
我會非常感激,如果有人能幫助我弄清楚爲什麼它在SOAP消息
"Server was unable to process request. ---> Data at the root level is
invalid"
我的代碼編譯說,而且運行良好
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();
}
}
}
}
}
我的輸出
