ngx.exec 会执行到别的项目里面

nginx version: openresty/1.19.9.1

ubuntu 20.04 apt安装的

upstream gateway-extra.xx.cn{
server 127.0.0.1;
}

upstream xx.com{
server 172.17.0.11;
}

server {
listen 80;
server_name xx.com;

location / {
    access_by_lua_file /data/gateway/index.lua;

    proxy_pass http://$host;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

location /gateway/extra/ {
    proxy_pass http://gateway-extra.xx.cn/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

}

server
{
listen 80;
server_name gateway-extra.xx.cn;
index index.html index.php;
root /data/gateway/extra/public;

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

location ~ [^/]\.php(/|$)
{
    try_files $uri $uri/ /index.php$is_args$args;

    fastcgi_pass  unix:/run/php/php7.4-fpm.sock;
    fastcgi_index index.php;
    include fastcgi.conf;
    fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/../../:/tmp/:/proc/";
}

}

/data/gateway/index.lua 里面

if uri == "/asd" then
return ngx.exec("/gateway/extra/verify")
end

这里的 ngx.exec("/gateway/extra/verify") 按理说应该放到到php项目里面去
但是大部分时候 会执行到服务器里面的默认项目（服务器里面有很多项目）
就是访问 xx.com/asd 显示的是默认项目的页面 但是有时候又正常 80%的情况到默认项目

Start with /data/gateway/index.lua and the two nginx server/location configurations, then reproduce requests to xx.com/asd while observing which server handles the internal redirect. Read the ngx.exec entry point and relevant nginx routing behavior before comparing the configured /gateway/extra/ path with the PHP project's server block. Done means the request consistently reaches the intended PHP project rather than the default site.
