Android 简便的异步Http连接框架

【Android + Java】简便的异步Http连接框架 

源代码地址：https://github.com/chenyoca/async-http-connection-core 

 * a multithread async http connection framework. it can be use on android project or common java project.

•   **简单** Async Http Connection为简单的Http连接请求而设计，提供POST和GET两个接口。通过参数和回调接口完成整个Http连接的交互。
•  **轻量** 纯JDK实现，不依赖第三方Jar包。
•  **快速** 采用Executor多线程并发框架，秉承它的并发处理优势。
•  **可扩展** 框架提供Invoker扩展，通过实现RequestInvoker可方便的把HttpClient等优秀框架整合到项目中。

//使用Get方法，取得服务端响应流：  AsyncHttpConnection http = AsyncHttpConnection.getInstance();  ParamsWrapper params = ...;  String url = ...  int requestId = http.get(url, null, new ResponseCallback() {      @Override   public void onResponse(InputStream response,URL url) {    System.out.println("[test GET] --> response back, url = "+url);    Assert.assertNotNull(response);    requestBack();   }      @Override   public void onError(Throwable exp) {    System.err.println("[test GET] --> response error, url = "+url);    requestBack();   }     @Override   public void onSubmit(URL url) {   }  });

//使用POST方法，取得服务端响应流：  AsyncHttpConnection http = AsyncHttpConnection.getInstance();  ParamsWrapper params = ...;  String url = ...  int requestId = http.post(url, null, new ResponseCallback() {      @Override   public void onResponse(InputStream response,URL url) {    System.out.println("[test POST] --> response back, url = "+url);    Assert.assertNotNull(response);    requestBack();   }      @Override   public void onError(Throwable exp) {    System.err.println("[test POST] --> response error, url = "+url);    requestBack();   }     @Override   public void onSubmit(URL url) {   }  });

### 更详细的例子 

//使用POST方法，取得服务端响应流：  AsyncHttpConnection http = AsyncHttpConnection.getInstance();  final int KEY_VAL = 24;  ParamsWrapper params = new ParamsWrapper();  params.put("firstname", "chen");  params.put("lastname", "yoca");  params.put("foo", KEY_VAL);  params.put("cookiename", KEY_VAL);  params.put("cookievalue", KEY_VAL);  int requestId = http.post(url, params, new StringResponseHandler() {     @Override   public void onSubmit(URL url) {     System.out.println(">> target: "+url.getHost()+" --> "+url.getPath());   }     @Override   public void onError(Throwable exp) {    requestBack();    exp.printStackTrace();   }     @Override   public void onResponse(String content, URL url) {    Assert.assertNotNull(content);    boolean containsKey = content.contains(String.valueOf(KEY_VAL));    Assert.assertEquals(true, containsKey);    requestBack();   }  });      //在大量并发的异步请求情况下，每个请求的回调可能需要一个标识码来标记这个回调结果。  //有两种方式来解决这个问题：  // 1、使用get和post返回的RequestID来标识，但这需要对RequestID进行管理  // 2、使用get和post的token参数    AsyncHttpConnection http = AsyncHttpConnection.getInstance();  final int KEY_VAL = 24;  ParamsWrapper params = new ParamsWrapper();  params.put("firstname", "chen");  params.put("lastname", "yoca");  params.put("foo", KEY_VAL);  params.put("cookiename", KEY_VAL);  params.put("cookievalue", KEY_VAL);    //  ******** 利用token 接口 ************  Object token = "1234566";    // 如果调用了带token的方法，回调的方法将是onResponse(String content, URL url, Object token)  int requestId = http.post(url, params, token, new StringResponseHandler() {     @Override   public void onSubmit(URL url) {     System.out.println(">> target: "+url.getHost()+" --> "+url.getPath());   }     @Override   public void onError(Throwable exp) {    requestBack();    exp.printStackTrace();   }     @Override   public void onResponse(String content, URL url, Object token) {    // token == "1234566" Token被传到这里作为标识    Assert.assertNotNull(content);    boolean containsKey = content.contains(String.valueOf(KEY_VAL));    Assert.assertEquals(true, containsKey);    requestBack();   }  });
