Python 古尼康公司；heroku的瓶子设置

我在heroku上玩瓶子游戏，想换一个更“生产”的WSGI服务器gunicorn。以下是我的设置：

import os
import bottle
from bottle import route, run, template, request, static_file, error

class StripPathMiddleware(object):
    def __init__(self, app):
        self.app = app
    def __call__(self, e, h):
        e['PATH_INFO'] = e['PATH_INFO'].rstrip('/')
        return self.app(e, h)

# ................................................................. #

@error(404)
def error404(error):
    return template('view/404.tpl')

app = bottle.app()
run(app=StripPathMiddleware(app), server='gunicorn', host='0.0.0.0', port=int(os.environ.get("PORT", 5000)), debug=True, workers=3)

这是我的程序文件：

我在SimpleServer.py应用程序中尝试了Procfile，设置了工人数量，也没有设置工人数量

在本地计算机上，它仅在应用程序中我有工人=3且我没有指定工人启动gunicorn:

但foreman start有个问题，不管我使用什么设置，我都会得到：

任何想法都将不胜感激！）

您正在启动gunicorn运行应用程序，然后使用生成另一台服务器（至少在Heroku上）。出现错误的原因是初始服务器使用端口5000，而第二台服务器无法访问该端口。试着运行你的瓶子应用程序（pythonsimpleserver.py），它应该创建服务器本身。此外，当您将“app”传递到run时，http服务器会生成您的应用程序的另一个副本（这会生成另一个gunicorn服务器），所以只需删除该副本即可

run(server='gunicorn', host='0.0.0.0', port=int(os.environ.get("PORT", 5000)), debug=True, workers=X)

python SimpleServer.py

应该就是你所需要的了。

谢谢，这很有道理。我丢失了一个WSGI“app”对象。有同样的问题。删除app.run（）对我很有效。谢谢
