网页发送请求到服务器,通过使用JSON发送HTTP请求到PHP网页服务器，在机器人(sending HTTP reques...

我希望所有人都做得很好。 我想添加Web服务是Android应用程序，为了这个，我已经创建了PHP服务器。 请求和响应是在JSON甲酸盐。 和请求类型是“后”这是我的要求甲：

{"method_name":"checkLogin","body": {"username":"someone@some.com","password":"password","device_type":"android","lat":"","long":""}}

预期的响应：

[{"status":"1","message":"Login successfully","data":{"id":"xx","username":"someone@some.com","first_name":"xxx","last_name":"yyy","gender":"xxx","relationship":"xxxx","birthdate":"xxxx","hometown":"","major":null,"class":null,"house":null,"device_type":"iphone","current_location_lat":"0.0","current_location_lon":"0.0","profile_image":"no_male_user.png","is_login":"1","created":"2012","status":"1","tag":[{"id":"x","tag_name":"xxxx"},{"id":"x","tag_name":"xxx xxx"}]}}]

我的Android代码：

userName = userNameField.getText().toString();

passWord = passWordField.getText().toString();

try {

JSONObject json = new JSONObject();

json.put("username", userName);

json.put("password", passWord);

json.put("device_type", "Android");

json.put("lat", "0.0");

json.put("long", "0.0");

JSONObject json1 = new JSONObject();

json1.put("method_name", "checkLogin");

json1.putOpt("body", json);

HttpParams httpParams = new BasicHttpParams();

HttpConnectionParams.setConnectionTimeout(httpParams,

TIMEOUT_MILLISEC);

HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);

HttpClient client = new DefaultHttpClient(httpParams);

HttpPost request = new HttpPost(URL);

request.setEntity(new StringEntity(json1.toString()));

ResponseHandler responseHandler = new BasicResponseHandler();

String response = client.execute(request, responseHandler);

Toast.makeText(this, response, Toast.LENGTH_LONG).show();

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} catch (Throwable t) {

Toast.makeText(this, "Request failed: " + t.toString(),

Toast.LENGTH_LONG).show();

}

}

{

$tagListArray['tag'][]= array("id"=> $rows['id'],"tag_name"=> $rows['tag_name']);

}

}

$finalArray = array_merge($arr_resp,$tagListArray);

$retArray[] = array("status" => "1","message" => "Login successfully","data" => $finalArray);

}

else

{

$retArray[] = array("status" => "0","message" => "The username or password you entered is incorrect");

}

return json_encode($retArray);

}

// End Login

}

?>

但是我得到空响应，而预期的响应，你可以帮我如何做到这一点的，谢谢你的帮助
