file_get_contents 通过代理发送 https 请求

Question

如何通过代理服务器进行 HTTPS 请求

Debian

上的代理服务器是 tinyproxy

代码

$context = stream_context_create([
    'http' => [
        'proxy' => 'tcp://xx.xx.xx.xx:8888',
        'request_fulluri' => true
    ]
]);

echo file_get_contents('https://www.google.com', false, $context);

错误

Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol in C:\wamp\www\google\test.php on line 10

Warning: file_get_contents(https://www.google.com): failed to open stream: Cannot connect to HTTPS server through proxy in C:\wamp\www\google\test.php on line 10

Answer 1

我建议使用 cURL 来执行此操作。在 Whosebug 的某个地方，一位用户这样说，我完全同意。

file_get_contents() is a simple screwdriver. Great for simple GET requests where the header, HTTP request method, timeout, cookiejar, redirects, and other important things do not matter. cURL with setopt is a powerdrills with almost every option you can think of.

<?php

$url = 'https://www.google.com';
// to check your proxy
// $url = 'http://whatismyipaddress.com/';
$proxy = '50.115.194.97:8080';

// create curl resource
$ch = curl_init();

// set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // read more about HTTPS 
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

// $output contains the output string
$output = curl_exec($ch);

// close curl resource to free up system resources
curl_close($ch); 

echo $output;

?>

Answer 2

导致第二次警告的问题可以通过将 stream_context_create 中的 'http' 更改为 'https'

来解决

file_get_contents 通过代理发送 https 请求

file_get_contents with https requests via proxy

php

https

fsockopen
