Using proxy with file_get_contents
提问by Jinu Joseph Daniel
I am getting data for my application from a website, say x.com. I use the php function file_get_contents() to fetch the data. It is sure that , my server's ip address will be shown in x.com 's logs. Is there any way to hide my server's ip without using proxy?
我正在从一个网站获取我的应用程序的数据，比如 x.com。我使用 php 函数 file_get_contents() 来获取数据。可以肯定的是，我的服务器的 IP 地址将显示在 x.com 的日志中。有没有办法在不使用代理的情况下隐藏我的服务器的 ip？
If I have a proxy ,how to use it with file_get_contents()?
如果我有代理，如何将它与 file_get_contents() 一起使用？

$context = stream_context_create($opts);
// Open the file using the HTTP headers set above
$file = file_get_contents('http://ifconfig.me/ip', false, $context);
var_dump($file);

Definitely agree with farmer1992.
绝对同意farmer1992。
For anyone having issues with file_get_contentsover SSL + proxy, there is a known bug with PHP's stream_context_create:
对于file_get_contents通过 SSL + 代理遇到问题的任何人，PHP 的 stream_context_create 存在一个已知错误：
https://bugs.php.net/bug.php?id=63519
https://bugs.php.net/bug.php?id=63519
Fortunately, the workaround is simple. Basically, the context creator gets confused when parsing an "https" target URL to both the proxy and SSL configs. You just have to set the SNI_server_namein the SSL config:
幸运的是，解决方法很简单。基本上，上下文创建者在将“https”目标 URL 解析为代理和 SSL 配置时会感到困惑。您只需要在 SSL 配置中设置SNI_server_name：
$targetUrl = "https://something.com";
$sniServer = parse_url($targetUrl, PHP_URL_HOST);
$params = array('your'=>'post','params'=>'here');
$ctxConfig = array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded'."\r\n",
'content' => http_build_query($params),
'proxy' => 'tcp://12.34.56.78:3128',
'request_fulluri' => true
),
'ssl' => array(
'SNI_enabled' => true,
'SNI_server_name' => $sniServer
)
);
$context = stream_context_create($ctxConfig);
file_get_contents($targetUrl,false,$context)
Hopefully that saves someone some time!
希望这可以节省一些时间！
