我对部署 python Web 应用程序相对较新，但我试图将我的 H2O wave 应用程序部署到 Heroku，但一直遇到问题，我在文档中找不到太多帮助。

如果我使用命令（在 SDK for wave 中）启动服务器，一切都在本地正常工作：

$ ./waved
2021/01/22 10:26:38 # 
2021/01/22 10:26:38 # ┌─────────────────────────┐

2021/01/22 10:26:39 # {"addr":"127.0.0.1:64065","route":"/tennis-pred","t":"ui_add"}
2021/01/22 10:46:04 # {"host":"http://127.0.0.1:8000","route":"/counter","t":"app_add"}

然后在项目的根目录下运行：

uvicorn tennis_pred_app:main

对于部署，除了我的 wave python 文件之外，我只有 arequirements.txt和 a Procfile：

web: uvicorn tennis_pred_app:main --host 0.0.0.0 --port 10101

这就是我的 foo (tennis_pred_app.py) 的样子（简化）：

from h2o_wave import Q, main, app, ui

@app("/tennis-pred")
async def serve(q: Q):
    show_form(q)
    await q.page.save()

我目前遇到的错误是：

你不能在 Heroku 上选择你的端口。相反， Heroku 通过环境变量为您分配一个端口PORT。

改变你Procfile的

web: uvicorn foo:main --host 0.0.0.0 --port 10101

至

web: uvicorn foo:main --host 0.0.0.0 --port $PORT
