PHP Curl - 返回的html都乱了 [英] PHP Curl - returned html all messed up

问题描述

我试图通过Curl获取一些关于网站文章的内容，我正在做如下操作：

I'm trying to fetch some contents about articles in a website via Curl, which I'm doing as follows :

    $url = 'http://lisboacity.olx.pt/oportunidade-pastor-alemao-7-meses-com-lop-iid-432402267';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322');
    curl_setopt($ch, CURLOPT_FAILONERROR, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_AUTOREFERER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    $data = curl_exec($ch);
    curl_close($ch);
    echo $data;

但是，正如你所看到的，结果类似于：

However, as you can see, the result is similar to this :

我也尝试用PHP的 DomDocument 类加载url内容，结果相同。

I've also tried to load the url contents with PHP's DomDocument class with the same result.

可能是什么原因？提前感谢！

What could be causing this? Thanks in advance!

推荐答案

输出是gzip编码的。尝试此选项以解压缩内容：

The output is gzip encoded. Try this option to decompress the content:

curl_setopt（$ ch，CURLOPT_ENCODING，''）;

curl_setopt($ch, CURLOPT_ENCODING, '');

CURLOPT_ENCODING：Accept-Encoding：头的内容。这使得能够解码响应。支持的编码为identity，deflate和gzip。如果设置了空字符串，则会发送包含所有支持的编码类型的标题。

CURLOPT_ENCODING: The contents of the "Accept-Encoding: " header. This enables decoding of the response. Supported encodings are "identity", "deflate", and "gzip". If an empty string, "", is set, a header containing all supported encoding types is sent.
