问题描述



我有幸通过静态文件访问静态文件这种方法,以及我使用google-fu实现了一个StaticFileHandler:

  import os 
import mimetypes
import webapp2
导入日志
$ b $ class StaticFileHandler(webapp2.RequestHandler):
def get(self,path):
abs_path = os.path.abspath(os.path.join (self.app.config.get('webapp2_static.static_file_path','static'),path))
if os.path.isdir(abs_path)或abs_path.find(os.getcwd())!= 0 :
self.response.set_status(403)
返回
尝试:
f = open(abs_path,'r')
self.response.headers.add_header('内容类型', mimetypes.guess_type(abs_path)[0])
self.response.out.write(f.read())
f.close()
除外:
self.response .set_status(404)

其中我的主要应用程序路由如下所示:

  app = webapp2.WSGIApplication([('/',HelloWorld),
(r'/ display',DisplayHandler),
r'/ static /(.+)',StaticFileHandler)
],debug = True)

我的css文件位于应用程序根目录下的文件夹中:/static/css/main.css



我可以通过直接url访问该文件,甚至可以链接它作为样式表,但样式不适用。有任何想法吗?是否有另一种方式来服务样式表?一些实现类似GAE的app.yaml的方法?

解决方案

你不需要一个静态文件处理程序。 >
将应用程序上传到您的 app.yaml

   -  url:/ static / 
static_dir:static

So I have successfully deployed an app using webapp2/jinja2 and a Paste server, but am having trouble serving static stylesheets.

I have had luck accessing static files via this method, as well as implementing a StaticFileHandler I found with some google-fu:

import os
import mimetypes
import webapp2
import logging

class StaticFileHandler(webapp2.RequestHandler):
    def get(self, path):
        abs_path = os.path.abspath(os.path.join(self.app.config.get('webapp2_static.static_file_path', 'static'), path))
        if os.path.isdir(abs_path) or abs_path.find(os.getcwd()) != 0:
            self.response.set_status(403)
            return
        try:
            f = open(abs_path, 'r')
            self.response.headers.add_header('Content-Type', mimetypes.guess_type(abs_path)[0])
            self.response.out.write(f.read())
            f.close()
        except:
            self.response.set_status(404)

where my main app routing looks like:

app = webapp2.WSGIApplication([('/', HelloWorld),
                               (r'/display', DisplayHandler),
                               (r'/static/(.+)', StaticFileHandler)
                              ], debug=True)

My css files are in a folder under the app root: /static/css/main.css

I can access the file via direct url, and even link it as a stylesheet, but the styles won't apply. Any ideas? Is there another way to serve stylesheets? Some way to implement an app.yaml similar to GAE?

解决方案

you dont need a static file handler.
upload the app with the static file folder by adding this to your app.yaml

- url: /static/
  static_dir: static

docs are here: https://developers.google.com/appengine/docs/python/config/appconfig#Static_Directory_Handlers
