How to make the HTTP connection timeout/disconnected after a time interval?
提问by mebada
I am new in Apache HttpClient, I used the following code to get the HTTP connection timeout (disconnected) after certain time interval:
我是 Apache 新手HttpClient，我使用以下代码在一定时间间隔后获取 HTTP 连接超时（断开连接）：
PostMethod method = new PostMethod(authURL);
HttpClient client = new HttpClient();
HttpClientParams params= new HttpClientParams();
params.setParameter(params.CONNECTION_MANAGER_TIMEOUT, 10); //10 Nano second
client.executeMethod(method);
but it wait for more than one minute without any hope to timeout/disconnect? Where can the problem be?
但它等待超过一分钟没有任何希望超时/断开连接？问题出在哪里？

There are 2 timeouts involved in HTTPClient, try to set both,
HTTPClient 中涉及 2 个超时，请尝试同时设置，
client.getHttpConnectionManager().
getParams().setConnectionTimeout(5000);
client.getHttpConnectionManager().
getParams().setSoTimeout(5000);
However, the values will be ignored if the connection is stuck in a native socket call. So you might have to run the request in a different thread so you can time it out. See my answer to this question on how to do that,
但是，如果连接卡在本机套接字调用中，这些值将被忽略。因此，您可能必须在不同的线程中运行请求，以便超时。请参阅我对这个问题的回答，了解如何做到这一点，

The connection manager timeout triggers when the act of trying to get a connection from your connection manager takes too long. This is not the same as the timeout for the http connection itself. Use HttpClientParams.setSoTimeout() instead.
当尝试从连接管理器获取连接的操作时间过长时，会触发连接管理器超时。这与 http 连接本身的超时时间不同。改用 HttpClientParams.setSoTimeout()。

Have you looked at setting SO_TIMEOUT?
你看过设置SO_TIMEOUT吗？
Sets the socket timeout (SO_TIMEOUT) in milliseconds to be used when executing the method. A timeout value of zero is interpreted as an infinite timeout.
设置执行方法时要使用的套接字超时 (SO_TIMEOUT) 以毫秒为单位。超时值为零被解释为无限超时。
