如何将 $request_uri 添加到 auth_request 模块?

how to Add $request_uri to auth_request module?

这是我的 nginx 配置文件:

location ~* ^/admin-panel/rest/(.*) {
    auth_request        /admin/admin_authentication/check_access?url=$request_uri;

    proxy_set_header    Host        $host;
    proxy_set_header    X-Real-IP   $remote_addr;

    resolver 127.0.0.11 ipv6=off;

    proxy_pass        http://nginx:8000/$is_args$args;
}

我想将 $request_uri 作为 GET 参数发送到我的身份验证服务。但我收到这样的错误:

2019/06/23 06:30:07 [error] 6#6: *5 auth request unexpected status: 
404 while sending to client, client: 192.168.224.1, server: , request: 
"POST /admin-panel/rest/update HTTP/1.1", host: "localhost"
2019/06/23 06:30:07 [error] 6#6: *8 auth request unexpected status: 
404 while sending to client, client: 192.168.224.1, server: , request: 
"POST /admin-panel/rest/update HTTP/1.1", host: "localhost"
2019/06/23 06:31:56 [error] 6#6: *1 auth request unexpected status: 
404 while sending to client, client: 192.168.224.1, server: , request: 
"POST /admin-panel/rest/update HTTP/1.1", host: "localhost"
2019/06/23 06:31:57 [error] 6#6: *3 auth request unexpected status: 
404 while sending to client, client: 192.168.224.1, server: , request: 
"POST /admin-panel/rest/update HTTP/1.1", host: "localhost"

当我删除 auth_request 中的 ?url=$request_uri 部分时,一切正常

通过使用 lua-nginx-module (or openresty docker 图像),您可以使用 access_by_lua_block 而不是 auth_request,如下所示:

location ~* ^/admin-panel/rest/(.*) {
    access_by_lua_block {
        local res = ngx.location.capture("/admin/admin_authentication/check_access?url=" .. ngx.var.request_uri)

        if res.status == ngx.HTTP_OK then
            return
        end

        if res.status == ngx.HTTP_FORBIDDEN then
            ngx.exit(res.status)
        end

        ngx.exit(ngx.HTTP_INTERNAL_SERVER_ERROR)
    }

    proxy_set_header    Host        $host;
    proxy_set_header    X-Real-IP   $remote_addr;

    resolver 127.0.0.11 ipv6=off;

    proxy_pass        http://nginx:8000/$is_args$args;
}

实际上,此代码使用 access_by_lua_block 实现 auth_request 并使用 Lua 连接运算符 ...
