有哪些优点和缺点背后重用 DefaultHTTPClient 从Android应用程序发送HTTP请求时到外部服务器？我试图用重复使用 DefaultHTTPClient 制作时，周期性 HTTPGET 的要求，但我得到随机插座超时（特别是使用3G的时候）

What are the pros and cons behind reusing DefaultHTTPClient when sending HTTP requests from an Android app to an external server? I tried using reusing a DefaultHTTPClient when making periodic HTTPGet requests, but I get random socket timeouts (specially when using 3G).

我的code看起来如下：

My code looks like follows:

public class MyHTTPSender { private DefaultHTTPClient mClient; public MyHTTPSender() { mClient = new DefaultHTTPClient(); } public void send(String httpAddress) { HttpGet get = new HttpGet(this.surrogateURL); HttpResponse response = null; try { response = httpClient.execute(get); // ... consume entity if OK } catch (Exception e) { } finally { if (response != null) { // do some sanity checks to ensure Entity is there! response.getEntity().consumeContent(); } } } }

我看不出什么问题，我在做什么。我有一个单独的处理程序，使HTTPPost请求，并且工作得很好（使用不同的DefaultHTTPClient对象）。

I can't see anything wrong with what I am doing. I have a separate handler that make HTTPPost requests, and that works perfectly well (uses a different DefaultHTTPClient object).

有什么建议？

推荐答案

什么API级别是你吗？

What API level are you on?

如果你是在8级以上，你可能会考虑尝试 AndroidHttpClient ，它可以指定一个较好的插座超时。

If you're on 8 or above you might consider trying AndroidHttpClient, which may have a better socket timeouts specified.

否则，你可能会检查你如何创建 DefaultHttpClient 并尝试指定更长的超时。

Otherwise, you might examine how you're creating the DefaultHttpClient and try specifying longer timeouts.
