问题描述
有些操作需要太多的时间,这导致Ajax请求超时。
Some operations take too much time, which lead the ajax request to time out.
我如何完成响应请求,再继续这样的操作?
How do I finish responding to the request first, then continue that operation?
推荐答案
在 ignore_user_abort
指令,并 ignore_user_abort
功能可能是你正在寻找的东西:它应该让你发送响应到浏览器,并在这之后,还是你的服务器上运行一些计算
The ignore_user_abort
directive, and ignore_user_abort
function are probably what you are looking for : it should allow you to send the response to the browser, and, after that, still run some calculations on your server.

基本上,当您使用 ignore_user_abort(真实)
在你的PHP 脚本,该脚本将继续 运行即使用户pressed的 ESC或停止对他的浏览器。你怎么 用这个?
一个用途是 返回内容给用户,并允许 连接被关闭时 处理的事情,不需要 用户交互。
下面的例子发出 $回应
用户,在关闭 连接(使浏览器的 微调/加载条停止),然后 执行时 do_function_that_takes_five_mins();
The following example sends out $response
to the user, closing the connection (making the browser’s spinner/loading bar stop), and then executes do_function_that_takes_five_mins();
和给定的例子:
ignore_user_abort(true);
header("Connection: close");
header("Content-Length: " . mb_strlen($response));
echo $response;
flush();
do_function_that_takes_five_mins();
(还有更多我没有复制粘贴)的
请注意,你的PHP脚本仍然以适应的max_execution_time
和 memory_limit的
的限制 - 这意味着你不应该使用这对于需要太时的操作。
Note that your PHP script still has to fit in the max_execution_time
and memory_limit
constraints -- which means you shouldn't use this for manipulations that take too much time.
这也将使用一个Apache进程 - 这意味着你不应该有几十页的做到这一点的同时
This will also use one Apache process -- which means you should not have dozens of pages that do that at the same time.
不过,漂亮的把戏,提升使用体验,我想, - )
Still, nice trick to enhance use experience, I suppose ;-)
