访问默认页面时，Bottle App 出现内部服务器错误

Question

我刚刚开始使用 Bottle。我在GitHub 上有一个示例应用程序。主模块 app.py（在 Application 文件夹中）如下所示

"""
This script runs the application using a development server.
"""

import bottle
import os
import sys

# routes contains the HTTP handlers for our server and must be imported.
import routes

if '--debug' in sys.argv[1:] or 'SERVER_DEBUG' in os.environ:
    # Debug mode will enable more verbose output in the console window.
    # It must be set at the beginning of the script.
    bottle.debug(True)

def wsgi_app():
    """Returns the application to make available through wfastcgi. This is used
    when the site is published to Microsoft Azure."""
    return bottle.default_app()

if __name__ == '__main__':
    PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
    STATIC_ROOT = os.path.join(PROJECT_ROOT, 'static').replace('\\', '/')
    HOST = os.environ.get('SERVER_HOST', 'localhost')
    try:
        PORT = int(os.environ.get('SERVER_PORT', '5555'))
    except ValueError:
        PORT = 5555

    @bottle.route('/static/<filepath:path>')
    def server_static(filepath):
        """Handler for static files, used with the development server.
        When running under a production server such as IIS or Apache,
        the server should be configured to serve the static files."""
        return bottle.static_file(filepath, root=STATIC_ROOT)

    # Starts a local test server.
    bottle.run(server='wsgiref', host=HOST, port=PORT)

requirements.txt 文件有

bottle
gunicorn

作为依赖项。我正在使用 Python 3.7.2。运行 pip install -r requirements.txt 后，

我运行了 python app.py。服务器启动，我可以访问默认页面没有错误错误

我尝试使用 gunicorn 运行服务器，如下所示

gunicorn -w 2 -b 0.0.0.0:8080 app:wsgi_app    

服务器启动正常，但是当我访问默认页面时，我得到了

Traceback (most recent call last):
  File "/Users/<user>/Codebase/test-bottle/venv/lib/python3.8/site-packages/gunicorn/workers/sync.py", line 134, in handle
    self.handle_request(listener, req, client, addr)
  File "/Users/<user>/Codebase/test-bottle/venv/lib/python3.8/site-packages/gunicorn/workers/sync.py", line 175, in handle_request
    respiter = self.wsgi(environ, resp.start_response)
TypeError: wsgi_app() takes 0 positional arguments but 2 were given

请让我知道我做错了什么。

Answer 1

您可以使用“应用程序工厂”模式（如 gunicorn documentation 中所述）在不修改代码的情况下运行应用程序：

gunicorn -w 2 -b 0.0.0.0:8080 'app:wsgi_app()'

请注意，您的页面不会完全显示，想。静态链接，例如css，不会加载，因为在这种情况下您没有在代码中定义任何路由：

def wsgi_app():
    """Returns the application to make available through wfastcgi. This is used
    when the site is published to Microsoft Azure."""
    return bottle.default_app()

Answer 2

您尝试过以下方法吗？

from bottle import route, run, static_file

@route('/')
def index():
    return '<h1>Hello Bottle!</h1>'
    @bottle.route('/static/<filepath:path>')

@route("/static//<filepath:re:.*")
def server_static(filepath):
    """Handler for static files, used with the development server.
    When running under a production server such as IIS or Apache,
    the server should be configured to serve the static files."""
    return bottle.static_file(filepath, root=STATIC_ROOT)



if __name__ == "__main__":
    run(host='localhost', port=5555)

app = bottle.default_app()

然后在控制台中：

gunicorn -w 4 your_app_name:app
