nginx中的$rule_0 1$rule_0 是什么意思?

Question

server {        listen        80;        server_name  www.baidu.com;        root   "xxx/frontend";        add_header Access-Control-Allow-Origin *;        add_header Access-Control-Allow-Headers X-Requested-With,Authorization,Content-Type,access-token,bloc-id,store-id;        add_header Access-Control-Allow-Methods GET,POST,OPTIONS,PUT,DELETE;        location / {            index index.php index.html error/index.html;            error_page 400 /error/400.html;            include D:/nginx.htaccess;            autoindex  off;        }        location ~ \.php(.*)$ {            fastcgi_pass   192.168.0.1;            fastcgi_index  index.php;        }        location /api {            index index.php index.html;            if (!-e $request_filename)            {                rewrite ^/api/(.*)$ /api/index.php last;            }            if (!-f $request_filename){                set $rule_0 1$rule_0;            }        }        location /admin {            index index.php index.html;            if (!-e $request_filename)            {                rewrite ^/admin/(.*)$ /admin/index.php last;            }            if (!-f $request_filename){                set $rule_0 1$rule_0;            }        }                 location /help {            index index.php index.html;            if (!-e $request_filename)            {                rewrite ^/help/(.*)$ /help/index.php last;            }            if (!-f $request_filename){                set $rule_0 1$rule_0;            }        }}

还有一个问题 我看这里写了3个 index index.php index.html 这种写3个代表了什么
是按照顺序找么?

Answer 1

$rule_0 是不是在 D:/nginx.htaccess 设置了，发下这个文件详情

index index.php index.html 第一个 index 是 nginx 指令，后面 index.php index.html 是表示按先后顺序默认访问哪个文件，即先访问 index.php 如果没有这个文件就访问 index.html
