【nginx&php】后台权限认证方式
一、最常用的方法(代码中限制)
1、如何限制IP
function get_new_ip(){if(getenv("HTTP_CLIENT_IP")) {
$onlineip = getenv("HTTP_CLIENT_IP");
} elseif(getenv("HTTP_X_FORWARDED_FOR")) {
$onlineip = getenv("HTTP_X_FORWARDED_FOR");
} elseif(getenv("REMOTE_ADDR")) {
$onlineip = getenv("REMOTE_ADDR");
} else {
$onlineip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}
return $onlineip;
}
$onlineip = get_new_ip();
$wip = ["127.0.0.1"];
if(!in_array($onlineip, $wip)){
header("HTTP/1.1 404 Not Found");
header("Status: 404 Not Found");
exit;
}
2、进行密码验证
///////////////// Password protect ////////////////////////////////////////////////////////////////define("ADMIN_USERNAME","test"); // Admin Username
define("ADMIN_PASSWORD","test"); // Admin Password
if (!isset($_SERVER["PHP_AUTH_USER"]) || !isset($_SERVER["PHP_AUTH_PW"]) ||
$_SERVER["PHP_AUTH_USER"] != ADMIN_USERNAME || $_SERVER["PHP_AUTH_PW"] != ADMIN_PASSWORD) {
Header("WWW-Authenticate: Basic realm="discuz Login"");
Header("HTTP/1.0 401 Unauthorized");
echo <<<EOB
<html><body>
<h1>Rejected!</h1>
<big>Wrong Username or Password!</big>
</body></html>
EOB;
exit;
}
////////// END OF DEFAULT CONFIG AREA /////////////////////////////////////////////////////////////
二、NGINX中限制
1、IP限制
官方文档:http://nginx.org/en/docs/http/ngx_http_access_module.html
location / {deny 192.168.1.1;
allow 192.168.1.0/24;
allow 10.1.1.0/16;
allow 2001:0db8::/32;
deny all;
}
2、auth_basic 本机认证(nginx默认支持)
官方文档:http://nginx.org/en/docs/http/ngx_http_auth_basic_module.html
安装密码工具
yum -y install httpd-tools生成密码
htpasswd -c pass.db
nginx中配置(需要维护 pass.db 文件)
auth_basic "User Authentication";
auth_basic_user_file conf/pass.db;
3、ngx_http_auth_request_module 第三方认证
需要安装:--with-http_auth_request_module 模块
#auth_basic "User Authentication";#auth_basic_user_file conf/pass.db;
auth_request /auth;
location = /auth {
proxy_pass ...
proxy_pass_request_body off;
proxy_set_header Content-Length "";
proxy_set_header X-Original-URI $request_uri;
}
这里可以反代到,http://www.auth.com/api/HttpBasicAuthenticate.php,代码如下:
///////////////// Password protect ////////////////////////////////////////////////////////////////define("ADMIN_USERNAME","test"); // Admin Username
define("ADMIN_PASSWORD","test"); // Admin Password
if (!isset($_SERVER["PHP_AUTH_USER"]) || !isset($_SERVER["PHP_AUTH_PW"]) ||
$_SERVER["PHP_AUTH_USER"] != ADMIN_USERNAME || $_SERVER["PHP_AUTH_PW"] != ADMIN_PASSWORD) {
Header("WWW-Authenticate: Basic realm="discuz Login"");
Header("HTTP/1.0 401 Unauthorized");
echo <<<EOB
<html><body>
<h1>Rejected!</h1>
<big>Wrong Username or Password!</big>
</body></html>
EOB;
exit;
}
////////// END OF DEFAULT CONFIG AREA /////////////////////////////////////////////////////////////
4、 ngx_http_auth_jwt_module 第三方认证
location / {auth_jwt "closed site";
auth_jwt_key_file conf/keys.json;
auth_jwt_claim_set $email info e-mail;
auth_jwt_claim_set $job info "job title";
}
加密算法原理同上
配置代码:
location ~ /admin/.*php$ {location = /admin.php {
allow 127.0.0.1;
deny all;
auth_basic "Authorized users only";
auth_basic_user_file authkey/auth.com.db;
fastcgi_pass common;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
