Nginx：404 Not Found错误作为反向代理答案

【问题标题】：Nginx: 404 Not Found error as reverse proxyNginx：404 Not Found错误作为反向代理
【发布时间】：2021-03-29 03:46:13
【问题描述】：

我正在尝试将 Nginx 配置为反向代理，让 Uvicorn 支持它。

当我尝试访问“example.com”时，它会返回主页，但会为所有静态文件提供 404。

当我尝试访问“example.com/blog”等任何其他端点时，它返回“404 not found”页面。

这里是 Nginx 配置：

server {

        root /var/www/example.com/html;
        index index.html index.htm index.nginx-debian.html;

        server_name example.com www.example.com;

        location / {
                try_files $uri $uri/ =404;

                #custom config
                proxy_set_header Host $http_host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection $connection_upgrade;
                proxy_redirect off;
                proxy_buffering off;
                proxy_pass http://uvicorn;
        }


    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen 80;
        listen [::]:80;

        server_name example.com www.example.com;

    return 404; # managed by Certbot


}

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

upstream uvicorn {
    server unix:/tmp/uvicorn.sock;
 }

我应该做哪些更改才能使其正常工作？

【问题讨论】：

【解决方案1】：

根据@richard-smith 在评论中给出的建议，我尝试将这一行注释掉

location / {
                #try_files $uri $uri/ =404;  <-- here

                #custom config
                proxy_set_header Host $http_host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection $connection_upgrade;
                proxy_redirect off;
                proxy_buffering off;
                proxy_pass http://uvicorn;
        }

而且效果很好。它现在能够为所有端点提供服务。
