CORS规定了从Apache .htaccess到nginx的覆盖范围 [英] CORS rules coversion from Apache .htaccess to nginx

问题描述

目前，我已经在我的Apache服务器上完美地使用了这些.htaccess规则:

Presently I have these .htaccess rules working perfectly on my Apache server:

<IfModule mod_headers.c>
    SetEnvIf Origin "https://(www\.)?(domain.com|beta.domain.com|domain.loc)$" AccessControlAllowOrigin=$0
    Header set Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header set Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept, X-CSRF-Token, X-XSRF-TOKEN"
    Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE, OPTIONS"
    Header set Access-Control-Allow-Credentials true
</IfModule>

<IfModule mod_rewrite.c>
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

最近切换到Nginx的决定要求我们实施相同的操作.我仍然对它的内部了解不多，确实需要帮助将其转换为它的nginx配置副本.

Recent decision to switch to nginx requires us to implement the same. I'm still getting a hang of its internals and really need help converting this into its nginx config counterpart.

到目前为止，我尝试过的操作:

server {
    listen 80;
    listen [::]:80;
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    include snippets/self-signed.conf;
    include snippets/ssl-params.conf;

    server_name api.mydomain.loc;

    root /var/www/mydomain/api/public;

    index index.html index.htm index.php;

    location / {
        if ($http_origin ~* https://(www\.)?(mydomain.loc)) {
            add_header Access-Control-Allow-Origin $http_origin;
            add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept, X-CSRF-Token, X-XSRF-TOKEN";
            add_header Access-Control-Allow-Methods "GET, POST, PUT, DELETE, OPTIONS";
            add_header Access-Control-Allow-Credentials true;
        }

        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Max-Age' 1728000;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204;
        }

        try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ \.php$ {
              try_files $uri =404;
              fastcgi_split_path_info ^(.+\.php)(/.+)$;
              fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
              fastcgi_index index.php;
              fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
              include fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }
}

我们将不胜感激.

推荐答案

问题中与Apache配置最简单的nginx等效项是，只需使用add_header并将其全部包装在执行正则表达式的if块中与$http_origin匹配:

The simplest nginx equivalent of the Apache config in the question would be, just use add_header and wrap it all in anif block that does a regex match against $http_origin:

location / {   
  if ($http_origin ~* https://(www\.)?(domain.com|beta.domain.com|domain.loc)) {
    add_header Access-Control-Allow-Origin $http_origin;
    add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept, X-CSRF-Token, X-XSRF-TOKEN";
    add_header Access-Control-Allow-Methods "GET, POST, PUT, DELETE, OPTIONS"
    add_header Access-Control-Allow-Credentials true
  }
  # use $http_authorization to get the value of the Authorization request header
}

nginx不需要您使用Apache进行的其他RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]操作；只需使用$http_authorization.

The extra RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] stuff that you need to do with Apache isn’t necessary with nginx; instead just use $http_authorization.

请注意，nginx中变量的变量以为前缀a>是特殊变量:

Note that variables in nginx that have names prefixed with $http_ are special variables:

$http_name
     任意请求标头字段；变量名称的最后一部分是字段名称
     转换为小写字母，并用下划线代替了短划线

$http_name
      arbitrary request header field; the last part of a variable name is the field name
      converted to lower case with dashes replaced by underscores

因此$http_origin为您提供Origin请求标头的值，$http_authorization为您提供Authorization请求标头的值，等等.

Thus $http_origin gives you the value of the Origin request header, $http_authorization gives you the value of the Authorization request header, etc.
