如何解决在访问默认页面时,Bottle App给出内部服务器错误
我刚开始使用Bottle。我在GitHub上有一个示例应用程序。主模块app.py(位于“应用程序”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文件具有
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pythonapp.py。服务器启动,我可以访问默认页面而不会出现错误错误
我尝试如下使用gunicorn运行服务器
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。
解决方法
您可以使用“应用程序工厂”模式运行应用程序,而无需修改代码(如粗体documentation中所述):
gunicorn -w 2 -b 0.0.0.0:8080 'app:wsgi_app()'
请注意,您的页面将无法完全显示。静态链接,例如CSS,将不会加载,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()
,
您尝试过以下吗?
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
