cUrl-获取html响应正文 [英] cUrl - getting the html response body

问题描述

我敢肯定这很简单。我正在使用下面的函数来检索网站原始html
进行解析。在测试过程中，我决定在stackoverflow.com上运行代码。

I'm sure this is fairly simple. I'm using the function below to retrieve sites raw html in order to parse it. during my testing, I decided to run my code on stackoverflow.com

Chrome并没有得到html响应，而是打印出了实际的网站，而是将html分配给了它的实际位置。名副其实的。我缺少什么？

Instead of getting the html response the Chrome is printing out the actual site rather then assigning the html to its veritable. What am I missing?

function get_site_html($site_url) 
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_COOKIESESSION, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_MAXREDIRS, 4);
    curl_setopt($ch, CURLOPT_FORBID_REUSE, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt($ch, CURLOPT_URL, $site_url);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $response = curl_exec($ch);

    global $base_url; 
    $base_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
    $http_response_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    curl_close ($ch);
    return $response;
}

网站原始html应该分配给$响应，然后将其返回。

The site raw html should be assigned to $response, and then return it.

推荐答案

您的代码有效。尝试 echo htmlentities（$ response）; 您将获得要卷曲的网站的原始html。

Your code works. Try echo htmlentities($response); You'll get the raw html for the site you're curling.
