nginx auth_request 示例

如何解决nginx auth_request 示例

我正在尝试用更用户友好、更吸引人的东西来代替 http 基本身份验证，而且最重要的是，我的密码管理器可以自动填充这些东西，尤其是在手机上。

我已从 this blog 复制了大部分内容，但此示例使用了跨域 cookie。

所以我做了一些小改动以使其与会话 cookie 一起工作。

这是我的示例文件：

/etc/nginx/nginx.conf

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

events {
  worker_connections 1024;
  use epoll;
}


http {
  include mime.types;
  default_type application/octet-stream;

  log_format main '$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" "$http_x_forwarded_for"';

  access_log /var/log/nginx/access.log main;

  sendfile on;
  tcp_nopush on;

  keepalive_timeout 0;

  gzip on;

  server {
    listen 80;
    listen [::]:80;
    server_name www.example.com;

    index index.php;

    root /var/www/secured;

    location / {
      auth_request /auth;
      try_files $uri $uri/ /index.php?$args;
    }

    location = /auth {
      internal;
      proxy_pass http://auth.example.com;
      proxy_pass_request_body off;
      proxy_set_header Content-Length "";
      proxy_set_header X-Original-URI $request_uri;
    }

    error_page 401 = @login;
    location @login {
      proxy_pass http://auth.example.com/?login&return=$http_host;
    }

    location = /logout {
      proxy_pass http://auth.example.com/?logout&return=$http_host;
    }

    location ~ \.php$ {
      fastcgi_pass 127.0.0.1:9000;
      include /etc/nginx/fastcgi.conf;
    }
  }

  server {
    listen 80;
    listen [::]:80;
    server_name auth.example.com;

    index index.php;

    root /var/www/auth;

    location / {
      try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
      fastcgi_pass 127.0.0.1:9000;
      include /etc/nginx/fastcgi.conf;
    }
  }
}

/var/www/auth/index.php

<?php
session_start();

if (!isset($_GET['login']) && !isset($_GET['logout'])) {
  if (isset($_SESSION['authorized']) && $_SESSION['authorized']) {
    http_response_code(200);
  } else {
    http_response_code(401);
  }
  die();
}

$error = "";
$loginUser = 'user';
$loginPass = 'pass';

$return = filter_input(INPUT_GET,'return');

if (isset($_GET['logout'])) {
  session_destroy();
  if (!empty($return)) {
    header("Location: http://{$return}");
  }
  die();
}

if (isset($_POST['submit'])) {
  $postUser = filter_input(INPUT_POST,'username');
  $postPass = filter_input(INPUT_POST,'password');

  $_SESSION['authorized'] = ($postUser === $loginUser && $postPass === $loginPass);
  if (!$_SESSION['authorized']) {
    $error = "Invalid username or password.";
  } else if (!empty($return)) {
    header("Location: http://{$return}");
    die();
  }
}
?>

我的问题和担心是：我是否在可靠的基本身份验证中戳了一个大洞？

谢谢
