android/java在项目中组织http web服务调用的结构/模式是什么？

Question

现在,只要我的项目在后端有一个Web服务.我习惯用这种结构/模式创建我的项目.

项目

• HttpMethods包
  • HttpGetThread
    
  • HttpPostThread
    
  • HttpMultipartPostThread
• 接口包
  • IPostResponse

我在这些JAVA文件中编写的代码是,

IPostResponse.java

public interface IPostResponse {
    public void getResponse(String response);
}

HttpGetThread.java

public class HttpGetThread extends Thread {

    private String url;
    private final int HTTP_OK = 200;
    private IPostResponse ipostObj;

    public HttpGetThread(String url, IPostResponse ipostObj) {
        this.url = url;
        this.ipostObj = ipostObj;
    }

    public void run() {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet(url);
            HttpResponse httpResponse = httpClient.execute(httpGet);
            int responseCode = httpResponse.getStatusLine().getStatusCode();
            if (responseCode == HTTP_OK) {
                InputStream inputStream = httpResponse.getEntity().getContent();
                int bufferCount = 0;
                StringBuffer buffer = new StringBuffer();
                while ((bufferCount = inputStream.read()) != -1) {
                    buffer.append((char) bufferCount);
                }
                ipostObj.getResponse(buffer.toString());
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

通过扩展和拥有一个构造函数和一个run方法,在类HttpPost和HttpMultipartPost类中的方式相同Thread.

然后,

我实现了一个活动的接口,并将该主活动扩展到所有其他活动,并通过使用参数和调用创建Http类的对象来获取响应和调用 obj.start();

---

我仍然相信:我缺少很多东西,或者这种结构很差.

我需要知道,对于Android应用程序来说,在大多数活动中实现Web服务调用,并且具有代码可重用性,我应该遵循哪种模式/结构？

我刚刚看到Facebook如何进行Web服务调用,例如登录/注销它有登录和注销侦听器.

是否有任何博客/文章/答案都有相同的文件记录？请问,任何用户都能分享他/她的优秀经验和解决方案吗？

我更感兴趣的是" 我的类和界面应该怎样,它应该采用哪种方法？ "

Answer 1

第一个也是大多数建议是为什么你不使用无痛线程，即AsyncTask

现在第二件事创建一个可重用的代码，如下所示，您可以创建尽可能多的带有请求参数的方法。

public class JSONUtil {

    private static JSONUtil inst;

    private JSONUtil() {

    }

    public static JSONUtil getInstance() {
        if (inst == null)
            inst = new JSONUtil();
        return inst;
    }

    /**
     * Request JSON based web service to get response
     * 
     * @param url
     *            - base URL
     * @param request
     *            - JSON request
     * @return response
     * @throws ClientProtocolException
     * @throws IOException
     * @throws IllegalStateException
     * @throws JSONException
     */
    public HttpResponse request(String url, JSONObject request)
            throws ClientProtocolException, IOException, IllegalStateException,
            JSONException {

        synchronized (inst) {

            DefaultHttpClient client = new DefaultHttpClient();
            HttpPost post = new HttpPost(url);
            post.setEntity(new StringEntity(request.toString(), "utf-8"));
            HttpResponse response = client.execute(post);
            return response;
        }
    }

    public HttpResponse request(String url)
            throws ClientProtocolException, IOException, IllegalStateException,
            JSONException {

        synchronized (inst) {

            DefaultHttpClient client = new DefaultHttpClient();             
            HttpPost post = new HttpPost(url);
            post.addHeader("Cache-Control", "no-cache");
            HttpResponse response = client.execute(post);
            return response;
        }
    }
}
