使用 PHP 获取原始请求

查看手册，似乎没有对请求进行未解析的原始访问以匹配您想要的内容，因此我怀疑您需要从变量中重新构建所需的内容。快速搜索我找到了这个类，做了一些小的改变来获得，也许你会发现它适合你的需求。$_SERVERGET / HTTP/1.1

<?php
/**
* Access the HTTP Request
* 
* Found on http://www.daniweb.com/web-development/php/code/216846/get-http-request-headers-and-body

class http_request {

    /** additional HTTP headers not prefixed with HTTP_ in $_SERVER superglobal */
    public $add_headers = array('CONTENT_TYPE', 'CONTENT_LENGTH');

    /**
    * Construtor
    * Retrieve HTTP Body
    * @param Array Additional Headers to retrieve
    */
    function http_request($add_headers = false) {

        $this->retrieve_headers($add_headers);
        $this->body = @file_get_contents('php://input');
    }

    /**
    * Retrieve the HTTP request headers from the $_SERVER superglobal
    * @param Array Additional Headers to retrieve
    */
    function retrieve_headers($add_headers = false) {

        if ($add_headers) {
            $this->add_headers = array_merge($this->add_headers, $add_headers);
        }

        if (isset($_SERVER['HTTP_METHOD'])) {
            $this->method = $_SERVER['HTTP_METHOD'];
            unset($_SERVER['HTTP_METHOD']);
        } else {

        $this->request_method = isset($_SERVER['REQUEST_METHOD']) ? $_SERVER['REQUEST_METHOD'] : false;

        $this->headers = array();
        foreach($_SERVER as $i=>$val) {
            if (strpos($i, 'HTTP_') === 0 || in_array($i, $this->add_headers)) {
                $name = str_replace(array('HTTP_', '_'), array('', '-'), $i);
                $this->headers[$name] = $val;
            }
        }
    }

    function method() {
        return $this->method;
    }

    /**

    function body() {
        return $this->body;
    }

    /** 
    * Retrieve an HTTP Header
    * @param string Case-Insensitive HTTP Header Name (eg: "User-Agent")
    */
    function header($name) {
        $name = strtoupper($name);
        return isset($this->headers[$name]) ? $this->headers[$name] : false;
    }

    /**
    * Retrieve all HTTP Headers 
    * @return array HTTP Headers

    function headers() {
        return $this->headers;
    }

    /**
    * Return Raw HTTP Request (note: This is incomplete)
    * @param bool ReBuild the Raw HTTP Request

    function raw($refresh = false) {

            return $this->raw; // return cached
        }
        $headers = $this->headers();
        $this->raw = "{$this->method} {$_SERVER['REQUEST_URI']} {$this->protocol}\r\n";

        foreach($headers as $i=>$header) {
                $this->raw .= "$i: $header\r\n";
        }
        $this->raw .= "\r\n{$this->body}";

原始请求对 PHP 不可用，因为在 PHP 启动时，该请求已被占用。

例如，当PHP作为Apache模块（）运行时，请求由Apache接收和解析，并且PHP仅在Apache解析该请求并确定它引用应由PHP处理的文件后调用。如果PHP作为CGI或FastCGI处理程序运行，它永远不会收到HTTP请求 - 它只能看到请求的CGI形式，这是完全不同的。mod_php
