任何人都可以告訴我如何通過給頭參數使用HttpHandler方法從API獲取響應?這是我的HttpHandler的java code`Android API集成
package com.example.addvehicle;
import android.util.Log;
import android.widget.ListView;
import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.ProtocolException;
import java.net.URL;
public class HttpHandler {
private static final String TAG = HttpHandler.class.getSimpleName();
public HttpHandler() {
}
public String makeServiceCall(String reqUrl) {
String response = null;
try{
URL url = new URL("http://garage.kaptastech.mobi/api/5k/users/vehicle");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
InputStream in = new BufferedInputStream(conn.getInputStream());
response = convertStreamToString(in);
}
catch (MalformedURLException e) {
Log.e(TAG, "MalformedURLException: " + e.getMessage());
}catch (ProtocolException e) {
Log.e(TAG, "ProtocolException: " + e.getMessage());
} catch (IOException e) {
Log.e(TAG, "IOException: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "Exception: " + e.getMessage());
}
return response;
}
private String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line;
try {
while ((line = reader.readLine()) != null) {
sb.append(line).append('\n');
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();``
}
}`
我需要添加兩個頭參數 1 - > ID 2 - > IMEI 如何添加,在我上面的HttpHandler的Java文件?請人幫助me.Many在此先感謝
msdev,我試過了。但仍然沒有得到任何迴應 – Arun
您使用http url連接導致異常:android.os.NetworkOnMainThreadException,這就是爲什麼你需要使用異步任務 – msdev16
