获取 PHP 中的完整 URL

a

ax.

看看$_SERVER['REQUEST_URI']，即

$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

（请注意，双引号字符串语法为 perfectly correct）

如果你想同时支持 HTTP 和 HTTPS，你可以使用

$actual_link = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

编者注：使用此代码具有安全隐患。客户端可以将 HTTP_HOST 和 REQUEST_URI 设置为它想要的任意值。

如果您在 https 链接上怎么办？如果 HTTP_HOST 不可用或被客户端篡改怎么办？这个答案似乎不完整且不可靠。

您对此无能为力，这是针对所提问题的正确方法。

您只需添加 HTTPS 的检查：'http' . (isset($_SERVER['HTTPS']) ? 's' : '') . '://' . "{$_SERVER['HTTP_HOST']}/{$_SERVER['REQUEST_URI']}"

如果您将 URL 作为链接输出到浏览器，只需关闭 http:。请参阅：stackoverflow.com/questions/4978235

在网页上输出链接的简短版本

$url =  "//{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";

$escaped_url = htmlspecialchars( $url, ENT_QUOTES, 'UTF-8' );
echo '<a href="' . $escaped_url . '">' . $escaped_url . '</a>';

以下是有关 the //example.com/path/ format 的问题和极端情况的更多详细信息

完整版本

function url_origin( $s, $use_forwarded_host = false )
{
    $ssl      = ( ! empty( $s['HTTPS'] ) && $s['HTTPS'] == 'on' );
    $sp       = strtolower( $s['SERVER_PROTOCOL'] );
    $protocol = substr( $sp, 0, strpos( $sp, '/' ) ) . ( ( $ssl ) ? 's' : '' );
    $port     = $s['SERVER_PORT'];
    $port     = ( ( ! $ssl && $port=='80' ) || ( $ssl && $port=='443' ) ) ? '' : ':'.$port;
    $host     = ( $use_forwarded_host && isset( $s['HTTP_X_FORWARDED_HOST'] ) ) ? $s['HTTP_X_FORWARDED_HOST'] : ( isset( $s['HTTP_HOST'] ) ? $s['HTTP_HOST'] : null );
    $host     = isset( $host ) ? $host : $s['SERVER_NAME'] . $port;
    return $protocol . '://' . $host;
}

function full_url( $s, $use_forwarded_host = false )
{
    return url_origin( $s, $use_forwarded_host ) . $s['REQUEST_URI'];
}

$absolute_url = full_url( $_SERVER );
echo $absolute_url;

这是 http://snipplr.com/view.php?codeview&id=2734 的大量修改版本（不再存在）

网址结构：

scheme://username:password@domain:port/path?query_string#fragment_id

粗体部分不包含在函数中

笔记：

此函数不包括来自完整 URL 或片段（散列）的用户名：密码。

它不会显示 HTTP 的默认端口 80 和 HTTPS 的端口 443。

仅使用 http 和 https 方案进行了测试。

#fragment_id 不会由客户端（浏览器）发送到服务器，也不会添加到完整的 URL 中。

$_GET 将只包含 foo=bar2 的 URL，例如 /example?foo=bar1&foo=bar2。

某些 CMS 和环境将重写 $_SERVER['REQUEST_URI'] 并为 /example?foo=bar1&foo=bar2 之类的 URL 返回 /example?foo=bar2，在这种情况下使用 $_SERVER['QUERY_STRING']。

请记住，URI = URL + URN，但由于普遍使用，现在 URL 表示 URI 和 URL。

如果您不打算使用代理或平衡器，则应删除 HTTP_X_FORWARDED_HOST。

规范说主机头必须包含端口号，除非它是默认号。

客户端（浏览器）控制变量：

$_SERVER['REQUEST_URI']。任何不受支持的字符在发送之前都会由浏览器进行编码。

$_SERVER['HTTP_HOST'] 并且根据 PHP 手册中的注释并不总是可用：http://php.net/manual/en/reserved.variables.php

$_SERVER['HTTP_X_FORWARDED_HOST'] 由平衡器设置，PHP 手册中的 $_SERVER 变量列表中未提及。

服务器控制变量：

$_SERVER['HTTPS']。客户端选择使用它，但服务器返回空或“on”的实际值。

$_SERVER['SERVER_PORT']。服务器只接受允许的数字作为端口。

$_SERVER['SERVER_PROTOCOL']。服务器只接受某些协议。

$_SERVER['SERVER_NAME'] 。根据 kralyk，它是在服务器配置中手动设置的，不适用于 IPv6。

What is the difference between HTTP_HOST and SERVER_NAME in PHP?
Is Port Number Required in HTTP "Host" Header Parameter?
https://stackoverflow.com/a/28049503/175071

如果服务器由 IPv6 IP 地址提供，则此代码将失败。要解决此问题，请将 SERVER_NAME 替换为 HTTP_HOST。

注意：对于像 /example?foo=bar1&foo=bar2 这样的网址，$_SERVER['REQUEST_URI'] 将显示 /example?foo=bar2

这将不包含在 # 之后定义的任何内容，这些内容不会传递到服务器

我不确定这是否没有安全风险。在您的示例中，您可以发送 Host 标头以到达正确的页面，但可能会让页面认为它是通过使用 HTTP_X_FORWARDED_HOST 标头的另一个主机调用的。当应用程序使用这些信息（不管是什么）时，它确实可能是一个安全问题，因为它允许您承诺一些并非如此的事情。

@Matt3o12 端口的值直接取自 Host 标头，没见过这样设置的，感谢提及，将作为调整添加

注意！！！

在上面的示例中手动使用了 hashtag # 部分，仅用于说明目的，但是，服务器端语言（包括 php）无法原生检测它们（只有 Javascript 可以做到这一点，因为 hashtag 只是浏览器/客户端功能）。

DIRECTORY_SEPARATOR 为 Windows 类型的主机返回 \，而不是 /。

# 部分在哪里，在服务器端我们无法访问# 之后的部分吗？

@RohitKhatri 该部分只能在浏览器中访问，不会发送到服务器

获取带有查询字符串的 url 的 wordpress 函数是什么？

警告：pathinfo() 不会像您期望的那样处理更复杂的 URL - 尽管参数中没有严格禁止 / 字符（请参阅 stackoverflow.com/questions/1455578/…），但解析此类 URL 不会为您提供脚本基名/文件名.试试print_r(pathinfo("https://example.com/subFolder/myfile.php?var=path/to/another/file.png"));

对我来说，我必须做 basename ($_SERVER["PHP_https://stackoverflow.com/questions/6768793/get-the-full-url-in-phpSELF"] ) 来获取没有查询字符串的主脚本名称（我需要它作为侧边栏链接列表中的主脚本）

Blackbam

这是使用 ternary statement 的解决方案，保持代码最少：

$url = "http" . (($_SERVER['SERVER_PORT'] == 443) ? "s" : "") . "://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

这是执行此操作的最小且最简单的方法，假设您的 Web 服务器为 HTTPS 使用标准端口 443。

或使用 $_SERVER["HTTPS"] == "on" 检查 SSL 是否打开。

您应该使用 $_SERVER["HTTPS"] 因为端口 443 只是默认的 SSL 端口，而不是 SSL 指示符。

@AlexBarker - 这就是为什么我说“假设一个网络服务器使用标准端口 443 进行 HTTPS”。

Y

Yukulélé

我最喜欢的查找当前 URL 的跨平台方法是：

$url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

关闭，但我需要将其更改为： $url = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

P

Peter Mortensen

只需使用：

$uri = $_SERVER['REQUEST_SCHEME'] . '://' . $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']

尽管我想使用它，但它在 IIS 中不起作用。 stackoverflow.com/questions/18008135/…

它输出什么？

PHP 注意：未定义索引：REQUEST_SCHEME

我喜欢这个解决方案！但是你也可以让它适用于 nginx 吗？

http://example.com :8080 /request.php 并失败。这些答案很复杂是有原因的。

TRiG

function full_path()
{
    $s = &$_SERVER;
    $ssl = (!empty($s['HTTPS']) && $s['HTTPS'] == 'on') ? true:false;
    $sp = strtolower($s['SERVER_PROTOCOL']);
    $protocol = substr($sp, 0, strpos($sp, '/')) . (($ssl) ? 's' : '');
    $port = $s['SERVER_PORT'];
    $port = ((!$ssl && $port=='80') || ($ssl && $port=='443')) ? '' : ':'.$port;
    $host = isset($s['HTTP_X_FORWARDED_HOST']) ? $s['HTTP_X_FORWARDED_HOST'] : (isset($s['HTTP_HOST']) ? $s['HTTP_HOST'] : null);
    $host = isset($host) ? $host : $s['SERVER_NAME'] . $port;
    $uri = $protocol . '://' . $host . $s['REQUEST_URI'];
    $segments = explode('?', $uri, 2);
    $url = $segments[0];
    return $url;
}

注意：我刚刚更新了 Timo Huovinen's code，因此您不会在 URL 中获得任何 GET 参数。此 URL 很简单，并删除了 ?hi=i&am=a&get 之类的内容。

例子：

http://www.example.com/index?get=information

将显示为：

http://www.example.com/index

这很好，除非你使用 GET 参数来定义一些特定的内容，在这种情况下你应该使用他的代码！ :-)

嘿，就是这样，很酷:)你也可以在哈希“#”（url片段）之后删除任何东西，以防它以某种方式滑入

不是真的，因为如果你在“explode('#',$segment[0])”中设置，它会被认为是错误，因为“#”符号破坏了URL，并且只能被Javascript读取。但是你可以做的是，可以肯定的是，你可以用“return trim($url,'#');”重新制作“return $url;”，因为这样你就会删除它，以防它在那里.但它不会删除以下内容。如果您愿意，可以阅读“Parse_url”。 :-)

清晰的代码，适用于所有网络服务器（Apache、nginx、IIS，...）：

$url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

P

Peter Mortensen

HTTP_HOST 和 REQUEST_URI 必须用引号引起来，否则在 PHP 7.2 中会抛出错误

利用：

$actual_link = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

如果要同时支持 HTTP 和 HTTPS：

$actual_link = (isset($_SERVER['HTTPS']) ? 'https' : 'http').'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

R

Rohit Gupta

与接受的答案相同的技术，但支持 HTTPS，并且更具可读性：

$current_url = sprintf(
    '%s://%s/%s',
    isset($_SERVER['HTTPS']) ? 'https' : 'http',
    $_SERVER['HTTP_HOST'],
    $_SERVER['REQUEST_URI']
);

上面给出了不需要的斜线。在我的设置 Request_URI 有前导和尾随斜杠。这对我来说效果更好。

$Current_Url = sprintf(
   '%s://%s/%s',
   isset($_SERVER['HTTPS']) ? 'https' : 'http',
   $_SERVER['HTTP_HOST'],
   trim($_SERVER['REQUEST_URI'],'/\\')
);

这是最简单、最干净的一个，并且可以正常工作。

为可读性加分，谢谢。

Peter Mortensen

这是我的解决方案 - 代码受 Tracy Debugger 启发。它已更改以支持不同的服务器端口。您可以获得完整的当前 URL，包括 $_SERVER['REQUEST_URI'] 或只是基本的服务器 URL。检查我的功能：

function getCurrentUrl($full = true) {
    if (isset($_SERVER['REQUEST_URI'])) {
        $parse = parse_url(
            (isset($_SERVER['HTTPS']) && strcasecmp($_SERVER['HTTPS'], 'off') ? 'https://' : 'http://') .
            (isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : (isset($_SERVER['SERVER_NAME']) ? $_SERVER['SERVER_NAME'] : '')) . (($full) ? $_SERVER['REQUEST_URI'] : null)
        );
        $parse['port'] = $_SERVER["SERVER_PORT"]; // Setup protocol for sure (80 is default)
        return http_build_url('', $parse);
    }
}

这是测试代码：

// Follow $_SERVER variables was set only for test
$_SERVER['HTTPS'] = 'off'; // on
$_SERVER['SERVER_PORT'] = '9999'; // Setup
$_SERVER['HTTP_HOST'] = 'some.crazy.server.5.name:8088'; // Port is optional there
$_SERVER['REQUEST_URI'] = '/150/tail/single/normal?get=param';

echo getCurrentUrl();
// http://some.crazy.server.5.name:9999/150/tail/single/normal?get=param

echo getCurrentUrl(false);
// http://some.crazy.server.5.name:9999/

注意：http_build_url 需要安装 pecl_http

P

Peter Mortensen

我制作了这个函数来处理 URL：

 <?php
     function curPageURL()
     {
         $pageURL = 'http';
         if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
         $pageURL .= "://";
         if ($_SERVER["SERVER_PORT"] != "80") {
             $pageURL .=
             $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
         }
         else {
             $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
         }
         return $pageURL;
     }
 ?>

P

Peter Mortensen

使用 Apache 环境变量很容易做到这一点。这仅适用于我假设您正在使用的 Apache 2。

只需使用以下 PHP 代码：

<?php
    $request_url = apache_getenv("HTTP_HOST") . apache_getenv("REQUEST_URI");
    echo $request_url;
?>

我试过这个 $actual_link = 'http' 。 (isset($_SERVER['HTTPS']) ? 's' : '') 。 '://' 。 "{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";

P

Peter Mortensen

使用这个单线查找父文件夹 URL（如果您无法访问 pecl_http 附带的 http_build_url()）：

$url = (isset($_SERVER['HTTPS']) ? 'https://' : 'http://').$_SERVER['SERVER_NAME'].str_replace($_SERVER['DOCUMENT_ROOT'], '', dirname(dirname(__FILE__)));

你混合 url 和文件在磁盘上的绝对位置

P

Peter Mortensen

这是您的问题的解决方案：

//Fetch page URL by this

$url = $_SERVER['REQUEST_URI'];
echo "$url<br />";

//It will print
//fetch host by this

$host=$_SERVER['HTTP_HOST'];
echo "$host<br />";

//You can fetch the full URL by this

$fullurl = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo $fullurl;

R

Ram Sharma

尝试这个：

print_r($_SERVER);

$_SERVER 是一个包含标头、路径和脚本位置等信息的数组。此数组中的条目由 Web 服务器创建。无法保证每个 Web 服务器都会提供其中任何一个；服务器可能会省略一些，或提供此处未列出的其他内容。也就是说，在 » CGI/1.1 规范中包含了大量这些变量，因此您应该能够预料到这些变量。

$HTTP_SERVER_VARS 包含相同的初始信息，但不是超全局的。（请注意，$HTTP_SERVER_VARS 和 $_SERVER 是不同的变量，PHP 会这样处理它们）

P

Pang

您可以使用不带参数的 http_build_url 来获取当前页面的完整 URL：

$url = http_build_url();

请注意，http_build_url() 只是一个 PECL 函数：(PECL pecl_http >= 0.21.0)

echo _URI::Parse('This is my current domain: %HostBase%

它仍然需要完善，但它是集中式 URI 系统的绝佳解决方案：D

我用了这个说法。

$base = "http://$_SERVER[SERVER_NAME]:$_SERVER[SERVER_PORT]$my_web_base_path";
$url = $base . "/" . dirname(dirname(__FILE__));

我希望这能帮到您。

以下是接受答案的更安全版本的基础，使用 PHP 的 filter_input 函数，这也弥补了 $_SERVER['REQUEST_URI'] 的潜在不足：

$protocol_https = filter_input(INPUT_SERVER, 'HTTPS', FILTER_SANITIZE_STRING);
$host = filter_input(INPUT_SERVER, 'HTTP_HOST', FILTER_SANITIZE_URL);
$request_uri = filter_input(INPUT_SERVER, 'REQUEST_URI', FILTER_SANITIZE_URL);
if(strlen($request_uri) == 0)
{
    $request_uri = filter_input(INPUT_SERVER, 'SCRIPT_NAME', FILTER_SANITIZE_URL);
    $query_string = filter_input(INPUT_SERVER, 'QUERY_STRING', FILTER_SANITIZE_URL);
    if($query_string)
    {
        $request_uri .= '?' . $query_string;
    }
}
$full_url = ($protocol_https ? 'https' : 'http') . '://' . $host . $request_uri;

您可以根据自己的喜好使用一些不同的 filters 对其进行调整。

我使用了下面的代码，它对我来说工作正常，对于 HTTP 和 HTTPS 两种情况。

function curPageURL() {
  if(isset($_SERVER["HTTPS"]) && !empty($_SERVER["HTTPS"]) && ($_SERVER["HTTPS"] != 'on' )) {
        $url = 'https://'.$_SERVER["SERVER_NAME"];//https url
  }  else {
    $url =  'http://'.$_SERVER["SERVER_NAME"];//http url
  }
  if(( $_SERVER["SERVER_PORT"] != 80 )) {
     $url .= $_SERVER["SERVER_PORT"];
  }
  $url .= $_SERVER["REQUEST_URI"];
  return $url;
}

echo curPageURL();

Demo

http和https的互换位置。

除非我弄错了，否则 $_SERVER['HTTPS'] = 'off' 将触发 HTTPS 路径。这似乎不对。另一方面，我也不认为原来的逻辑是正确的。

非常简单的使用：

function current_url() {
    $current_url  = ( $_SERVER["HTTPS"] != 'on' ) ? 'http://'.$_SERVER["SERVER_NAME"] :  'https://'.$_SERVER["SERVER_NAME"];
    $current_url .= ( $_SERVER["SERVER_PORT"] != 80 ) ? ":".$_SERVER["SERVER_PORT"] : "";
    $current_url .= $_SERVER["REQUEST_URI"];

    return $current_url;
}

嗨，鉴于此页面上已经有多少个答案，您能否添加一些解释，说明为什么这比其他答案更好，或者它有什么不同？

嗨，确实有很多解决方案，我的功能简单、干净且易于理解。

这适用于 HTTP 和 HTTPS。

echo 'http' . (($_SERVER['HTTPS'] == 'on') ? 's' : '') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

输出类似这样的东西。

https://example.com/user.php?token=3f0d9sickc0flmg8hnsngk5u07&access_level=application

您可以使用 HTTP_ORIGIN，如下面的代码段所示：

if ( ! array_key_exists( 'HTTP_ORIGIN', $_SERVER ) ) {
    $this->referer = $_SERVER['SERVER_NAME'];
} else {
    $this->referer = $_SERVER['HTTP_ORIGIN'];
}

我觉得这个方法很好..试试看

if($_SERVER['HTTP_HOST'] == "localhost"){
    define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT']);
    define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/');
    define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/');
}
else{
    define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']);
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT']);
    define('TEMPLATE', $_SERVER['DOCUMENT_ROOT'] . '/incs/template/');
    define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/');
    define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/');
}

$page_url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

这个答案是从上面复制的。

是的，除了变量之外，这与 stackoverflow.com/a/23717829/446106 相同（在撰写本文时）
