java – 随时从另一个线程取消文件下载

我正在使用HttpURLConnection下载文件.我可以从另一个线程取消下载吗？如果没有,应该使用什么文件下载方法？

我的建议是使用 HttpClient

而不是HttpUrlConnection.这是一个更好的图书馆在许多方面.

然后,您可以使用：

final SimpleHttpConnectionManager connectionManager = 
            new SimpleHttpConnectionManager();
final HttpClient client = new HttpClient(connectionManager);

// ... and when it's time to close the connection from another thread
connectionManager.shutdown();

如果您需要跨多个线程关闭多个连接,则可以重复使用一个HttpClient实例,并以类似的方式将它们全部关闭：

static MultiThreadedHttpConnectionManager connectionManager = 
            new MultiThreadedHttpConnectionManager();
// HttpClient instance that can be shared across threads and create multiple connections
static HttpClient client = new HttpClient(connectionManager);

// ... and when it's time to close connections
connectionManager.shutdown();
