我是前端Web应用程序开发的新手.我收到的WebSocket连接失败如下:

WebSocket connection to 'ws://127.0.0.1:7983/websocket/' failed: Error in connection establishment: net::ERR_EMPTY_RESPONSE

我查看了这个WebSocket错误,发现转到了以下页面.

Shiny&RStudio Server:"WebSocket握手期间出错:意外的响应代码:404"

使用nginx,nodejs和socket.io,WebSocket连接失败

Rstudio和闪亮的服务器代理设置

然后我在我的Windows 7机器上下载了nginx,并在nginx.conf中添加了以下注释,保存并执行了runApp().

location /rstudio/ {
 rewrite ^/rstudio/(.*)$ /$1 break;
 proxy_pass http://localhost:7983;
 proxy_redirect http://localhost:7983/ $scheme://$host/rstudio/;
}

这似乎没有解决问题.我想我可能需要在nginx.conf文件中添加一些额外的东西,或者将它放在特定的目录中.请协助.谢谢!

编辑nginx.conf脚本如下:

        location /rstudio/ {
    rewrite ^/rstudio/(.*)$ /$1 break;
    proxy_pass http://127.0.0.1:5127;
    proxy_redirect http://127.0.0.1:5127/ $scheme://$host/rstudio/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    }

我有这个错误请求.

德语中的最后一句是指"Firefox无法连接到位于ws:// ......."的服务器.

服务器不会是我认为的问题.

因为这里是nginx配置,因为我觉得有问题!

server {
    server_name example.org;
    listen 80 default_server;
    root /var/www/web;

    location / # for symfony2
    {
        try_files $uri @rewriteapp;
    }

    location @rewriteapp # for symfony2
    {
                rewrite ^(.*)$ /app.php/$1 last;
    }

    location ~ ^/app\.php(/|$)
    {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param HTTPS off;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location ~ ^/socket
    {
        proxy_pass http://127.0.0.1:8080;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $http_host;
    }

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;
}

nginx版本:nginx/1.4.7

app.js(那就是服务器!)

var …

在我的服务器上运行nginx(nginx/1.1.19)上的socket.io时出错

WebSocket握手期间出错:'Connection'标头值不是'Upgrade':keep-alive

我的网站的conf文件是:

server{
    listen 80;
    server_name lalala.com;
    access_log /home/hao/sites/reactjsweekly/accesss.log;
    error_log /home/hao/sites/reactjsweekly/error.log;
    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:3002/;
        proxy_redirect off;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

后端的socket.io:

var server = http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
});

var io = require('socket.io').listen(server);  

io.sockets.on('connection', function (socket) {
socket.emit('info', {data: "lala"});



  });

});

任何人遇到同样的问题之前???
