With Apache HttpClient, why isn't my connection timeout working?
提问by
My implementation of httpclient occasionally throws an exception when calling doGetConnection(). However, I have the following timeout set
我的 httpclient 实现在调用 doGetConnection() 时偶尔会抛出异常。但是，我设置了以下超时
_moHttpClient.setHttpConnectionFactoryTimeout(30000);
it looks almost like my timeout is not being picked up. Is there anywhere else I need to set a timeout to ensure this behaviour does not re-occur
看起来我的超时几乎没有被接受。是否还有其他地方需要设置超时以确保不会再次发生此行为

HttpConnectionManagerParams cmparams = new HttpConnectionManagerParams();
cmparams.setSoTimeout(10000);
cmparams.setTcpNoDelay(true);
HttpConnectionManager manager = new SimpleHttpConnectionManager();
manager.setParams(cmparams);
params = new HttpClientParams();
params.setSoTimeout(5000);
client = new HttpClient(params, manager);
I wonder why I have two different SoTimeouts set. Maybe I was trying to find out which one was actually active, as I had the same problems as you when I used it.
我想知道为什么我设置了两个不同的 SoTimeouts。也许我想找出哪个是真正活跃的，因为我在使用它时遇到了与您相同的问题。
The above is in live code at our place right now, but I cannot say whether it works because it's correct, or because providence is smiling down on me (and the other end is usually always available).
以上是我们现在的实时代码，但我不能说它是否有效，因为它是正确的，或者因为天意对我微笑（而另一端通常总是可用的）。

cmparams.setSoTimeout(10000);
cmparams.setSoTimeout(10000);
This one is for all HttpClient by default.
默认情况下，这是针对所有 HttpClient 的。
params.setSoTimeout(5000);
params.setSoTimeout(5000);
And this one is for a particular httpclient.
这是针对特定的 httpclient。

What exception are you getting thrown ?
你会抛出什么异常？
Don't forget you have twotimeouts to change/check. From HttpConnectionParams
不要忘记您有两个超时要更改/检查。从HttpConnectionParams
setConnectionTimeout()
setSoTimeout()
so you can control how long you wait for a connection to the server, and how long operations on the socket can take before timing out.
因此您可以控制等待连接到服务器的时间，以及在超时之前对套接字的操作需要多长时间。
