Websocket在本地工作，但不在Heroku - PHP应用程序上运行 - Websocket work locally but not on Heroku - PHP application

我已经很久没有使用Heroku了，所以我有点生疏。我创建了一个运行Ratchet IOServer的小型PHP应用程序。它侦听端口 5000。如果我运行heroku local并连接telnet localhost 5000一切似乎都正常。我已经尝试了几种让PHP进程运行和接受连接的方法。

我的Procfile看起来像这样;

web: php bin/console bot:start

跑步heroku local

Downloading forego-0.16.1 to /Users/roje/.heroku... done
forego | starting web.1 on port 8080
web.1  | It works!
web.1  | New connection! (97)
web.1  | Connection 97 sending message "sdfdfs"

当我然后将服务器部署到 Heroku 时，它不起作用。当我尝试远程登录到端口 5000 上的框时，我得到

telnet myapplication.herokuapp.com 5000
Trying 46.137.127.234...
telnet: connect to address 46.137.127.234: Connection refused
telnet: Unable to connect to remote host

有什么建议吗？

我刚刚阅读了有关 Heroku 分配动态端口 Heroku + 节点的部分.js错误（Web 进程在启动后 60 秒内无法绑定到$PORT）

我尝试在该端口上收听，但仍然无法通过telnet连接。虽然我确实得到了一些有趣的日志。也许你们中的一些人正在尝试IP地址？

不过，我仍然遇到同样的错误。

我能够使用 nginx 作为 Web 套接字前面的代理来管理它。

文件：

web: private/bin/start_socket vendor/bin/heroku-php-nginx -C nginx_app.conf

start_socket：

php private/bin/start_socket.php &
exec "$@"

start_socket.php：

<?php
require_once(dirname(dirname(__DIR__)) . '/vendor/autoload.php');
require_once(__DIR__ . '/socket/socket.php');
use Ratchet'Server'IoServer;
use Ratchet'Http'HttpServer;
use Ratchet'WebSocket'WsServer;
$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Socket()
        )
    ),
    8085
);
$server->run();

nginx.conf：

location /wss {
    proxy_pass http://localhost:8085;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

现在您可以像这样访问套接字：ws://myapp.com/wss?mydata=test。这并不能回避每个测功机都将运行其自己唯一的WebSocket服务器的事实，但这是一个完全独立的问题。

根据 Floss 的回答...这就是为我提供由 bloatless/php-websocket 提供支持的 WebSocket 的原因。类似的东西也可能适用于瑞奇。

文件：

web: bash start vendor/bin/heroku-php-nginx -C nginx.conf

开始：

php server.php &
exec "$@"

nginx.conf：

location /app {
    proxy_pass http://localhost:1112;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Sec-WebSocket-Protocol $http_sec_websocket_protocol;
    proxy_set_header Sec-WebSocket-Extensions $http_sec_websocket_extensions;
    proxy_set_header Sec-WebSocket-Key $http_sec_websocket_key;
    proxy_set_header Sec-WebSocket-Version $http_sec_websocket_version;
}

server.php将是为您的 websockets 应用程序提供服务的任何 PHP 文件。

:1112将是您设置了要在其上运行 Websockets 应用程序的任何端口。

/app将是您需要为无臃肿设置的应用程序名称。

注意：根据您使用的客户端，您可能还需要设置其他 websocket 标头。websocket 标头的完整列表可以在这里找到：https://www.rfc-editor.org/rfc/rfc6455#section-11.3
