javascript - 如何修复 nginx 上的 http 414 Request-URI Too Large 错误？

Question

我希望所有进入我的网络服务器的流量都重定向到 Nginx 上的 https。但是，当我在 http://www.example.com 访问我的网站时，我收到错误“414 Request-URI Too Large”并且 URL 长得离谱 -- http://www.example.com/http:://www.example.com/http: : - 它持续了一段时间，我假设这是给我这个错误的原因。但是我不知道如何解决这个重定向错误，因为我的 Nginx 配置文件不包含 $request_uri 参数。

这是 Nginx 配置文件:

server {
    server_name  example.com;
    return 301 https://www.example.com;

listen 443 ssl; 
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; 
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; 
include /etc/letsencrypt/options-ssl-nginx.conf; 
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; 
}

server {
 root /var/www/html;
 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
    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name www.example.com;
    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            proxy_pass http://localhost:8080; #whatever port your app runs on
            proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;      
        }
    }

  
server {
  if ($host = www.example.com) {
     return 301 https://www.example.com;
  } 


  if ($host = example.com) {
    return 301 https://www.example.com;
  } 
  listen 80 default_server;
  server_name  example.com www.example.com;
  return 404; 
}

如有任何帮助，我们将不胜感激!

我解决了这个问题:

1. 打开你的 nginx.conf 文件 /etc/nginx/conf.d/nginx.conf

2. 在http中加入这段代码

fastcgi_buffers 8 16k;
fastcgi_buffer_size 32k;

client_max_body_size 24M;
client_body_buffer_size 128k;

client_header_buffer_size 5120k;
large_client_header_buffers 16 5120k;

1. 使用service nginx reload重新加载您的 nginx
