在heroku上部署aiohttp

问题描述

我在 aiohttp 上构建了一个简单的 Web 服务器并尝试将它部署在 heroku 上，但在部署后我收到一条错误消息:

I have built a simple web server on aiohttp and try to deploy it on heroku, but after deployment I get an error message:

at=error code=H14 desc="No web processes running" dyno= connect= service= status=503 bytes= protocol=https

项目结构:

├── application.py
├── Procfile
├── requirements.txt
├── routes.py
└── views
    ├── bot_team_oranizer.py
    ├── index.py
    └── __init__.py

application.py

from aiohttp import web
from routes import setup_routes

app = web.Application()
setup_routes(app)
web.run_app(app)

Procfile:

web: gunicorn application:app

为什么网络服务器没有在 heroku 上启动?

Why is the web server not starting on heroku?

推荐答案

可能 aiohttp 没有监听正确的端口.你需要像 web.run_app(app, port=os.getenv('PORT')) 之类的东西.

Probably aiohttp isn't listening on the right port. You need something like web.run_app(app, port=os.getenv('PORT')).

更新: 等等，您正在尝试同时使用 gunicorn 和 web.run_app 来提供它，这是错误的，您需要使用类似web: python application.py 或删除web.run_app(app).

Update: wait, you're trying to serve it both with gunicorn and with web.run_app which is wrong, you'll need to either just have something like web: python application.py or remove the web.run_app(app).
