【问题描述】：

当前 nginx 配置：

server 
    listen 443 ssl http2;
    server_name NAME www.NAME;
    charset utf-8;
    ssl on;
    ssl_certificate /etc/nginx/ssl/NAME-cert.pem;
    ssl_certificate_key /etc/nginx/ssl/NAME-key.pem;

    location /static/ 
        alias /home/ubuntu/NAME/static_collection/;
    

    location /media/ 
    alias /home/ubuntu/NAME/media_collection/;
    

    location / 
        proxy_pass http://localhost:8002;

    proxy_redirect off;
    proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    

一切正常，除了 websockets。我想这是因为它不处理 http 升级标头...我查看了文档，但我无法弄清楚如何在不破坏其他任何内容的情况下修改此配置。

【参考方案1】：

试试这个。让我知道它是否有效。

server 
    listen 443 ssl http2;
    server_name NAME www.NAME;
    charset utf-8;
    ssl on;
    ssl_certificate /etc/nginx/ssl/NAME-cert.pem;
    ssl_certificate_key /etc/nginx/ssl/NAME-key.pem;

    location /static/ 
        alias /home/ubuntu/NAME/static_collection/;
    

    location /media/ 
    alias /home/ubuntu/NAME/media_collection/;
    

    location / 
        proxy_pass http://localhost:8002;

        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_http_version 1.1;
        proxy_read_timeout 86400;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    

【讨论】：

我使用的是 HTTP2，这有什么改变吗？反正我现在就试试。谢谢！
