=====================
- a multithread callback-based async http connection library. it can be use on android project or general java project.
- 一个基于回调机制的多线程异步Http连接库。它可用于Android项目或者一般Java项目。
Async HTTP Connection为简单的Http连接请求而设计。适用于API SDK等小数据传输项目,设计目标为Android项目。
当前项目属性为Java项目,并使用JUnit4作为测试环境,主要是Android项目调试不方便。
如果需要完善的功能,推荐一位国外大神的项目:[android-async-http](https://github.com/loopj/android-async-http)
- 简单 提供POST和GET两个接口,通过扩展接口可设置PUT、DELETE方法。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。
在多线程测试中,如果并发多条线程,则测试主线程需要等待所在测试子线程全部返回后才结束。一般采用两种方式:1、Thread.sleep()方式。2、CountDown计数方式。
所有问题的的解决方式都不只有一种,看谁的方式更好更——优雅而已。
比如:本框架内置多线程测试辅助工具组合 ResponseCallbackTrace + ThreadWaiter。可以利用简单的几个方法,就解决并发线程等待的问题。
使用方法很简单
- 创建回调接口动态代理
protected final ResponseCallbackTrace callbackTrace = new ResponseCallbackTrace();
ResponseCallbackTrace 是一个动态代理实现类,它可以监听 ResponseCallback 的调用。并将线程执行情况记录在ThreadWaiter中。
- 对回调接口添加代理
for(String url : urls){
http.get(url, null,
// 使用回调动态代理,可以自动处理等待其它线程返回的问题
callbackTrace.trace(callback));
}
- 等待所有线程返回
//等待所有线程返回
ThreadWaiter.waitingThreads();
public class UrlsTestCase{
final static String[] AvailableUrls = {

默认使用SimpleHttpInvoker类执行Http连接,基于HttpUrlConnection实现。 提供两个接口实现类:BinaryResponseHandler、StringResponseHandler。分别处理二进制数据和字符数据。

//使用Get方法,取得服务端响应流:

// callback with Stream
int requestId = http.post(url, params, new ResponseCallback() {
@Override

// 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();
}
});
需要使用其它Http Mehtod,可以通过
* sendRequest(String url,ParamsWrapper params,HttpMethod method,Object token,ResponseCallback callback)
* sendRequest(String url,ParamsWrapper params,HttpMethod method, ResponseCallback callback)
接口调用。
