开源项目之Android async-http(异步 HTTP 客户端开发包)

AsyncHttpClient 这个类库可以在Java应用程序中执行HTTP 请求并异步处理HTTP响应。用法非常简单。

项目如图：

源码分析：

public class AsyncHttpResponseHandler { //请求返回处理成功失败开始完成等自定义的消息

public class BinaryHttpResponseHandler extends AsyncHttpResponseHandler { //字节流返回处理该库用于处理图片等

public class JsonHttpResponseHandler extends AsyncHttpResponseHandler { //json请求返回处理服务器与客户端用json交流时使用

class AsyncHttpRequest implements Runnable { //基于线程异步请求通过AsyncHttpResponseHandler回调

public class PersistentCookieStore implements CookieStore { //HttpClient处理数据使用cookie持久性存储接口

public class RequestParams { //封装了参数处理例如：

 * RequestParams params = new RequestParams(); * params.put("username", "james"); * params.put("password", "123456"); * params.put("email", "my@email.com"); * params.put("profile_picture", new File("pic.jpg")); // Upload a File * params.put("profile_picture2", someInputStream); // Upload an InputStream * params.put("profile_picture3", new ByteArrayInputStream(someBytes)); // Upload some bytes * * AsyncHttpClient client = new AsyncHttpClient(); * client.post("http://myendpoint.com", params, responseHandler);

class RetryHandler implements HttpRequestRetryHandler {//多个线程同步处理

public class SerializableCookie implements Serializable { //操作cookie 放入/取出数据

class SimpleMultipartEntity implements HttpEntity { //处理多个请求实体封装

public abstract class SyncHttpClient extends AsyncHttpClient { //同步客户端请求

public class AsyncHttpClient { //异步客户端请求如：

 * AsyncHttpClient client = new AsyncHttpClient(); * client.get("http://www.google.com", new AsyncHttpResponseHandler() { * @Override * public void onSuccess(String response) { * System.out.println(response); * } * });

操作实例如：

    private static AsyncHttpClient client = new AsyncHttpClient();    public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {        client.get(getAbsoluteUrl(url), params, responseHandler);    }    public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {        client.post(getAbsoluteUrl(url), params, responseHandler);    }    private static String getAbsoluteUrl(String relativeUrl) {        return BASE_URL + relativeUrl;    }
