Question

我用弗拉斯克(Flask)建立一个网络服务,我正试图用Paster(Paster)来部署一个简单的“哈罗,世界”应用程序。我很难把一切都配置到一起工作。我看过Google关于使用虚拟和Zcbuilt(Vievenv)和Zcbuildout(Zcbuilt)用粘贴器用粘贴器运行弗拉斯克的网络服务,但对于一个非常基本的应用程序来说,这似乎有点过份。现在,当我试图用我的应用程序加载一个 URL(URL) 时,我得到这个错误:

Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/paste/httpserver.py", line 1068, in process_request_in_thread
  self.finish_request(request, client_address)
File "/usr/lib/python2.7/SocketServer.py", line 323, in finish_request
  self.RequestHandlerClass(request, client_address, self)
File "/usr/lib/python2.7/SocketServer.py", line 639, in __init__
  self.handle()

File "/usr/lib/python2.7/dist-packages/paste/httpserver.py", line 287, in wsgi_execute
  self.wsgi_start_response)
AttributeError: GraffitiApp instance has no __call__ method

我的应用程序配置看起来像 :

[DEFAULT]
loglevel = WARN
browser_cache_ttl = 30

[app:main]
use = egg:GraffitiService

[server:main]
use = egg:Paste#http
host = 0.0.0.0
port = %(graffiti_port)s

我的应用程序代码看起来像:

from flask import Flask

app = Flask(__name__)
app.debug = True

class GraffitiApp:

    @app.route( / )
    def hello_world():
        return "Hello World!"

    @app.route( /other )
    def other_page():
        return "Other page!"

    def main():
        app.run(debug = True)

if __name__ == "__main__":
    app.run(debug = True)

我是否需要创建方法, 并绘制任何 URL 传送到相应函数的地图, 还是需要更改我的配置?

<强 > EDIT

我使用一家工厂, 名为主. Py, 因为错误,

import logging

from graffiti import GraffitiApp

def make_app(globalArgs, **localArgs):
    loglevelname = globalArgs.get("loglevel", "INFO").lower()

    if loglevelname ==  critical :
        loglevel = logging.CRITICAL
    elif loglevelname ==  debug :
        loglevel = logging.DEBUG
    elif loglevelname ==  error :
        loglevel = logging.ERROR
    elif loglevelname ==  fatal :
        loglevel = logging.FATAL
    elif loglevelname ==  info :
        loglevel = logging.INFO
    elif loglevelname ==  warn  or loglevelname ==  warning :
        loglevel = logging.WARN
    else:
        loglevel = logging.NOTSET
        loglevelname =  notset 

    FORMAT = "%(asctime)s %(name)s %(levelname)s %(message)s"
    logging.basicConfig(format = FORMAT, level = loglevel)
    logging.info("Log level set to %s" % (loglevelname.upper()))

    return GraffitiApp()

Answer 1

看起来服务器正在尝试运行您的 GraffitiApp () clask () example app 类, 当它应该运行 Flask () exience app 时。

Answer 2

弗特普(抱歉,但你的密码让我目不转睛):

import logging

from graffiti import GraffitiApp

def make_app(globalArgs, **localArgs):
    loglevelname = globalArgs.get("loglevel", "INFO")
    loglevel = getattr(logging, loglevelname.upper(), logging.NOTSET)


    FORMAT = "%(asctime)s %(name)s %(levelname)s %(message)s"
    logging.basicConfig(format = FORMAT, level = loglevel)
    logging.info("Log level set to %s" % (loglevelname))

    return GraffitiApp()
