php - 加载大页面后的卷曲警报

Question

我正在使用以下命令来获取 URL 的内容。

$result = curl_exec($ch);

我想解析结果文本。现在我正在做的是$result在等待固定延迟后解析 的内容，以确保加载整个页面并且页面的全部内容可通过变量$result.

有没有其他方法可以识别整个页面是否已加载？

Answer 1

Unless you're using curl_multi_exec, curl_exec will not return anything until the entire page is loaded, so there is no need to do what you are trying to do. From the manual page:

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

It won't return anything and your script won't continue until the transfer has finished.

Edit::

It is a bit confusing what is actually happening, but it looks like you are displaying the HTML contents of a page to the browser and that page is redirecting the user to a new page. I'm guessing that this is either a javascript or meta refresh. The only way to prevent this from happening is by parsing through the HTML and removing those elements.

Try adding header('Content-type: text/plain'); to the top of your script and you will see what is actually returned by curl.

Answer 2

你不需要延迟或其他东西。

当您从 curl 返回结果时，它包含整个页面。
