Android Http响应不工作

我有一个注册部分，其中用户名和密码被发送到使用rest服务进行解析。这很好。在登录部分，我想检查用户名和密码是否在解析中注册，因此我接受http响应，但代码中有一些错误。由于某种原因，反应不会回来

我的登录成功完整方法如下：

private boolean loginSuccesfull() throws ClientProtocolException, IOException {
        // TODO Auto-generated method stub
        InputStream result = null;
        HttpClient httpClient = new DefaultHttpClient();
        HttpGet get = new HttpGet("https://api.parse.com/1/classes/Login?where={"+"\"UserName\""+":"+"\"abc\""+"}"); 
        HttpResponse response = httpClient.execute(get);
        if (response != null && response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            BufferedHttpEntity bufferedHttpEntity = new BufferedHttpEntity(response.getEntity());
            result = bufferedHttpEntity.getContent();
            return true;
        }else {
            // insert error handling
            return false;
        }       
    }

解析服务器有一个内置的登录表，我们可以通过在该表中添加用户名和密码来使用该表，并按照该表检查登录是否成功

ParseUser parseUser = new ParseUser();
                parseUser.logInInBackground( mEtUserName.getText().toString()
                        .trim()
                        ,mEtPswd.getText().toString(),new LogInCallback() {
                    @Override
                    public void done(ParseUser arg0, com.parse.ParseException arg1) {
                        if(arg1==null ){
                            startActivity(new Intent(LoginActivity.this,CaptureActivity.class));
                        } 
                        else{
                            arg1.printStackTrace();
                            Toast.makeText(LoginActivity.this,"UserName or Password is Incorrect", 0).show();
                        }
                    }
                });

为此，我们必须首先使用以下代码在解析中注册用户名和密码

HttpPost request = new HttpPost(SERVICE_URI);
            request.addHeader("X-Parse-Application-Id",
                    "e7ynC0ZB1ts5EQVpghywywoUUCNafT4XZnoJO3j5");
            request.addHeader("X-Parse-REST-API-Key",
                    "w9iInpo0kPmzibzjyCkhyjO199tc5V0vqtafL2yW");
            request.addHeader("Content-Type", "application/json");
            // Build JSON string
            JSONStringer TestApp = null;

            try {
                TestApp = new JSONStringer().object().key("username")
                        .value(mStrUname).key("password").value(mStrPswd).key("FullName").value(mStrFullName)
                        .endObject();
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();                   
            }

            StringEntity entity = null;

            try {
                entity = new StringEntity(TestApp.toString());
            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            Log.d("****Parameter Input****", "Testing:" + TestApp);
            request.setEntity(entity);
            // Send request to WCF service
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpResponse response = null;

            try {
                response = httpClient.execute(request);
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            Log.d("WebInvoke", "Saving: " + response.getStatusLine().toString());
            // Get the status of web service
            BufferedReader rd = null;
            try {
                rd = new BufferedReader(new InputStreamReader(
                        response.getEntity().getContent()));
            } catch (IllegalStateException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            // print status in log
            String line = "";
            try {
                while ((line = rd.readLine()) != null) {
                    Log.d("****Status Line***", "Webservice: " + line);

                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

            return null;
        }

logcat中是否有错误？url中是否有任何内容需要使用UrlEncode（）？是否使用解析库？如果不是，我建议你那样做。与手动发出http请求相比，他们的jar文件为您提供了一个更好的接口来与他们的API交互。@SiddharthVyas-ya我在我的query中遇到了非法参数异常错误，但query正在parse@jyomin所有这些都包含在解析文档中。另外，请查看快速入门指南。感谢各位的回答，我用上面的方法完成了。
