Heroku-Web 进程未能在启动后 90 秒内绑定到 $PORT.TooTallNate Websockets [英] Heroku- Web process failed to bind to $PORT within 90 seconds of launch. TooTallNate Websockets

问题描述

我正在使用一个完整的 websockets 服务器来侦听来自网站的连接.

I'm using a tootallnate websockets server listening for connections from a website.

如何在 heroku 上连接到我的服务器?

当我的网站尝试连接时

wss://Heroku-Name-39329.herokuapp.com/

或

wss://Heroku-Name-39329.herokuapp.com:5000/

我的 heroku 记录输出.

My heroku logs output.

at=error code=H10 desc="App crashed" method=GET path="/" host=wss://Heroku-Name-39329.herokuapp.com request_id=4afca002-2078-439c-85dc-ad6ef7db50d2 fwd="207.244.77.23" dyno= connect= service= status=503 bytes=

然后(仍然是 Heroku 日志)

And then(Still Heroku Logs)

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 90 seconds of launch
Stopping process with SIGKILL
Process exited with status 137

State changed from crashed to starting
Starting process with command `java $JAVA_OPTS -cp target/classes/:target/dependency/* v1.a1.server

我的 javascript 日志

My javascript logs

WebSocket connection to 'wss://Heroku-Name-39329.herokuapp.com/:5000/' failed: Establishing a tunnel via proxy server failed.

我在服务器中设置的应用程序是.

My Apps set within the server are.

String host = "";
int port = 5000;

我的档案

web: java $JAVA_OPTS -cp target/classes/:target/dependency/* v1.a1.server

推荐答案

试试这个:

String host = "0.0.0.0";
int port = System.getenv("PORT");

在 Heroku 上，您必须绑定到 0.0.0.0 并使用分配给您的应用的端口，该端口包含在 $PORT 环境变量中.

On Heroku, you must bind to 0.0.0.0 and use the port assigned to your app, which is contained in the $PORT environment variable.

从客户端，您不需要指定端口，因此只应使用 wss://Heroku-Name-39329.herokuapp.com/(而不是带有 5000 的端口).

From the client, you will not need to specify a port, so only wss://Heroku-Name-39329.herokuapp.com/ should be used (not the one with 5000).
