PHP file_get_contents() 和设置请求标头

2022-01-17 00:00:00 http-headers php

使用 PHP，是否可以使用 file_get_contents() 发送 HTTP 标头?

With PHP, is it possible to send HTTP headers with file_get_contents() ?

我知道您可以从 php.ini 文件中发送用户代理.但是，您也可以使用 file_get_contents() 发送其他信息，例如 HTTP_ACCEPT、HTTP_ACCEPT_LANGUAGE 和 HTTP_CONNECTION 吗?

I know you can send the user agent from your php.ini file. However, can you also send other information such as HTTP_ACCEPT, HTTP_ACCEPT_LANGUAGE, and HTTP_CONNECTION with file_get_contents() ?

或者是否有其他功能可以做到这一点?

Or is there another function that will accomplish this?

推荐答案

其实进一步阅读file_get_contents()函数:

// Create a stream
$opts = [
    "http" => [
        "method" => "GET",
        "header" => "Accept-language: en
" .
            "Cookie: foo=bar
"
    ]
];

// DOCS: https://www.php.net/manual/en/function.stream-context-create.php
$context = stream_context_create($opts);

// Open the file using the HTTP headers set above
// DOCS: https://www.php.net/manual/en/function.file-get-contents.php
$file = file_get_contents('http://www.example.com/', false, $context);

您也许可以按照这种模式来实现您想要的，不过我还没有亲自测试过.(如果它不起作用，请随时查看我的其他答案)

You may be able to follow this pattern to achieve what you are seeking to, I haven't personally tested this though. (and if it doesn't work, feel free to check out my other answer)
