file_get_contents 不适用于某些 url [英] file_get_contents is not working for some url

问题描述

我在 PHP 中使用 file_get_contents.在下面的第一个 URL 代码中工作正常，但第二个不起作用.

I use file_get_contents in PHP. In the below code in first URL works fine but the second one isn't working.

$URL = "http://test6473.blogspot.com";
$domain = file_get_contents($URL);
print_r($domain);


$add_url= "http://adfoc.us/1575051";
$add_domain = file_get_contents($add_url);
echo $add_domain;

关于为什么第二个不起作用的任何建议?

Any suggestions on why the second one doesn't work?

推荐答案

file_get_contents 未检索到的 URL，因为他们的服务器会检查请求是来自浏览器还是来自任何脚本.如果他们发现来自脚本的请求，他们只需禁用页面内容.

URL which is not retrieved by file_get_contents, because their server checks whether the request come from browser or any script. If they found request from script they simply disable page contents.

所以我必须发出类似于浏览器请求的请求.所以我使用以下代码来获取第二个 url 内容.对于不同的 Web 服务器，它可能会有所不同.因为他们可能会保留不同的支票.

So that I have to make a request similar as browser request. So I have used following code to get 2nd url contents. It might be different for different web server. Because they might keep different checks.

尽管您为什么不尝试使用以下代码！如果你幸运的话，这可能对你有用！！

Even though why dont you try to use following code! If you are lucky this might work for you!!

function getUrlContent($url) {
    fopen("cookies.txt", "w");
    $parts = parse_url($url);
    $host = $parts['host'];
    $ch = curl_init();
    $header = array('GET /1575051 HTTP/1.1',
        "Host: {$host}",
        'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'Accept-Language:en-US,en;q=0.8',
        'Cache-Control:max-age=0',
        'Connection:keep-alive',
        'Host:adfoc.us',
        'User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.116 Safari/537.36',
    );

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
    curl_setopt($ch, CURLOPT_COOKIESESSION, true);

    curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
    curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

$url = "http://adfoc.us/1575051";
$html = getUrlContent($url);
