Node.js 通过nginx的socket.io返回传输未知错误

我正在尝试通过Nginx连接到我的Nodejs服务器

我的服务器在端口3000上运行，我的Nodejs客户端使用成功连接到服务器，同时返回：

我使用certbot进行SSL认证，它配置了我的nginx.conf

location /socket.io/ {
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://127.0.0.1:3000/socket.io/;
}

这是mysocket.io服务器的Nginx.conf文件：

upstream nodesocket {
        server  127.0.0.1:3000;
}

server {
        listen                  443 ssl;
        server_name             example.com www.example.com;

        access_log              /var/log/nginx/access-ssl.log;
        error_log               /var/log/nginx/error-ssl.log;

        ssl_session_cache       shared:SSL:10m;
        ssl_session_timeout     10m;

        large_client_header_buffers 8 32k;


        location /socket.io/ {
                proxy_pass              https://nodesocket;
                proxy_redirect off;

                proxy_http_version      1.1;

                proxy_set_header        Upgrade                 $http_upgrade;
                proxy_set_header        Connection              "upgrade";

                proxy_set_header        Host                    $host;
                proxy_set_header        X-Real-IP               $remote_addr;
                proxy_set_header        X-Forwarded-For         $proxy_add_x_forwarded_for;
        }
}

const express = require('express')
const https = require('https')
const socketIo = require('socket.io')
var fs = require('fs')

var options = {
    cert: fs.readFileSync('/etc/letsencrypt/live/example.com/fullchain.pem'),
    key: fs.readFileSync('/etc/letsencrypt/live/example.com/privkey.pem'),
    ca: fs.readFileSync('/etc/letsencrypt/live/example.com/chain.pem')
}

var app = express();
var server = https.createServer(options, app);
var io = socketIo(server);


server.listen(3000, function(){
    console.log('listening on :3000');
  });

这是我的socket io服务器：

upstream nodesocket {
        server  127.0.0.1:3000;
}

server {
        listen                  443 ssl;
        server_name             example.com www.example.com;

        access_log              /var/log/nginx/access-ssl.log;
        error_log               /var/log/nginx/error-ssl.log;

        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; 

        ssl_protocols           SSLv3 TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers             RC4:HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers on;

        ssl_session_cache       shared:SSL:10m;
        ssl_session_timeout     10m;

        large_client_header_buffers 8 32k;


        location /socket.io/ {
                proxy_pass              https://nodesocket;
                proxy_redirect off;

                proxy_http_version      1.1;

                proxy_set_header        Upgrade                 $http_upgrade;
                proxy_set_header        Connection              "upgrade";

                proxy_set_header        Host                    $host;
                proxy_set_header        X-Real-IP               $remote_addr;
                proxy_set_header        X-Forwarded-For         $proxy_add_x_forwarded_for;
        }
}

const express = require('express')
const https = require('https')
const socketIo = require('socket.io')
var fs = require('fs')

var options = {
    cert: fs.readFileSync('/etc/letsencrypt/live/example.com/fullchain.pem'),
    key: fs.readFileSync('/etc/letsencrypt/live/example.com/privkey.pem'),
    ca: fs.readFileSync('/etc/letsencrypt/live/example.com/chain.pem')
}

var app = express();
var server = https.createServer(options, app);
var io = socketIo(server);


server.listen(3000, function(){
    console.log('listening on :3000');
  });

我检查了nodejs和nginx日志，但没有相关的日志，也没有错误。

我遇到了完全相同的问题，这对我很有效

我删除了

proxy\uhttp\u1.1版

这是我的nginx.conf

location /socket.io/ {
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://127.0.0.1:3000/socket.io/;
}

我尝试了相同的方法，但仍然面临{“代码”：0，“消息”：“传输未知”}
