默认的www跳转和SLL后开启的定向都是302？怎么改301

默认的www跳转和SLL后开启的定向都是302？怎么改301加permanent;    }？？还是用重定向功能

加permanent 就可以了

官方推荐 return 301,rewrite 复杂而且性能差

his server block forces all visitors to use a secured (SSL/TLS) connection to your site.

server {
    listen 80;
    server_name www.domain.com;
    return 301 https://www.domain.com$request_uri;
}
Some other blogs about NGINX rewrite rules use an if test and the rewrite directive for this use case, like this:

# NOT RECOMMENDED
if ($scheme != "https") {
    rewrite ^ https://www.mydomain.com$uri permanent;
}
But this method takes extra processing because NGINX must both evaluate the if condition and process the regular expression in the rewrite directive.

所以是这样吗？

1. server {
   
2.     listen 80;
   
3.     server_name www.pualab.com;
   
4.     return 301 https://www.pualab.com$request_uri;
   
5. }
   
6. 
   
7. server {
   
8.     listen 443 ssl;
   
9.     server_name www.pualab.com pualab.com;
   
10.     index index.php index.html index.htm default.php default.htm default.html;
    
11.     root /www/wwwroot/pualab;
    
12.     #error_page 404/404.html;
    
13.     ssl_certificate    /etc/letsencrypt/live/pualab.com/fullchain.pem;
    
14.     ssl_certificate_key    /etc/letsencrypt/live/pualab.com/privkey.pem;
    
15.     error_page 497  https://$host$uri;
    
16.     #error_page 404 /404.html;
    
17.     error_page 502 /502.html;
    
18.    
    
19.     include enable-php-70.conf;
    
20.     include /www/server/panel/vhost/rewrite/pualab.com.conf;
    
21.     location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    
22.     {
    
23.         expires      30d;
    
24.         access_log off;
    
25.     }
    
26.     location ~ .*\.(js|css)?$
    
27.     {
    
28.         expires      12h;
    
29.         access_log off;
    
30.     }
    
31.     access_log  /www/wwwlogs/pualab.com.log;
    
32. }
