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.
