http连接超时问题 [英] http connection timeout issues

问题描述

当我尝试使用 HttpClient 连接时遇到问题到一个网址.即使在我设置之后，http 连接也需要更长的时间才能超时连接超时.

I'm running into an issue when i try to use the HttpClient connecting to a url. The http connection is taking a longer time to timeout, even after i set a connection timeoout.

int timeoutConnection = 5000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);

int timeoutSocket = 5000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

它在大多数情况下都能完美运行.但是，每隔一段时间，http 连接就会永远运行并忽略 setconnectiontimeout，尤其是当手机连接到 wifi 并且手机空闲时.

It works perfect most of the time. However, every once in while, the http connection runs for ever and ignore the setconnectiontimeout, especailly when the phone is connected to wifi, and the phone was idling.

所以在手机空闲后，我第一次尝试连接时，http 连接会忽略 setconnectiontimeout 并永远运行，在我取消它并重试后，它每次都像魅力一样.但是有一次它不起作用它会创建一个 threadtimeout 错误，我尝试使用不同的线程，它可以工作，但我知道该线程运行了很长时间.

So after the phone is idling, the first time i try to connect, the http connection ignores the setconnectiontimeout and runs forever, after i cancel it and try again, it works like charm everytime. But that one time that doesn't work it creates a threadtimeout error, i tried using a different thread, it works, but i know that the thread is running for long time.

我知道 wifi 在空闲时进入睡眠状态，但我不明白为什么它会忽略 setconnectiontimeout.

I understand that the wifi goes to sleep on idle, but i dont understand why its ignoring the setconnectiontimeout.

任何人都可以提供帮助，非常感谢.

Anyone can help, id really appreciated.

推荐答案

不确定这是否对您有帮助，但我认为值得在这里分享.在使用超时内容时，我发现您可以分配第三种超时类型:

Not sure if this helps you, however I think it's worth sharing here. While playing with the timeout stuff I found there is a third timeout type you can assign:

// the timeout until a connection is established
private static final int CONNECTION_TIMEOUT = 5000; /* 5 seconds */

// the timeout for waiting for data
private static final int SOCKET_TIMEOUT = 5000; /* 5 seconds */

// ----------- this is the one I am talking about:
// the timeout until a ManagedClientConnection is got 
// from ClientConnectionRequest
private static final long MCC_TIMEOUT = 5000; /* 5 seconds */

...

HttpGet httpGet = new HttpGet(url);
setTimeouts(httpGet.getParams());

...

private static void setTimeouts(HttpParams params) {
    params.setIntParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 
        CONNECTION_TIMEOUT);
    params.setIntParameter(CoreConnectionPNames.SO_TIMEOUT, SOCKET_TIMEOUT);
    params.setLongParameter(ConnManagerPNames.TIMEOUT, MCC_TIMEOUT);
}
