本地環境是在windows上 安裝了phpstudy, 今天打開電腦突然訪問本地頁面， 502!, 好端端的怎麼突然就502了呢，什麼也沒改啊，別的域名都可以正常訪問，唯獨這個 https的端口爲443的報502，
打開錯誤日誌error.log:

去網上搜了半天，然後改了一個配置好了；
location ~ \.php(.*)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi_params;
}
fasctcgi_pass, 由原來的9001，改成了9000， 解決！
