Google App Engine和404错误 [英] Google App Engine and 404 error

问题描述

我使用其他地方的提示在GAE上设置了一个静态网站，但无法弄清楚如何返回404错误。我的app.yaml文件看起来像

I've setup a static website on GAE using hints found elsewhere, but can't figure out how to return a 404 error. My app.yaml file looks like

- url: (.*)/
  static_files: static\1/index.html
  upload: static/index.html

- url: /
  static_dir: static

，所有静态html / jpg文件存储在静态目录下。上述工作适用于存在的文件，但如果不存在则返回空长文件。答案可能是编写一个python脚本来返回一个404错误，但是你如何设置一些东西来为存在的静态文件提供服务，但是为那些没有的文件运行脚本？

with all the static html/jpg files stored under the static directory. The above works for files that exist, but returns a null length file if they don't. The answer is probably to write a python script to return a 404 error, but how do you set things up to serve the static files that exist but run the script for files that don't?

以下是从开发应用程序服务器上获取不存在的文件（nosuch.html）的日志：

Here is the log from fetching a non-existent file (nosuch.html) on the development application server:

ERROR    2008-11-25 20:08:34,084 dev_appserver.py] Error encountered reading file "/usr/home/ctuffli/www/tufflinet/static/nosuch.html":
[Errno 2] No such file or directory: '/usr/home/ctuffli/www/tufflinet/static/nosuch.html'
INFO     2008-11-25 20:08:34,088 dev_appserver.py] "GET /nosuch.html HTTP/1.1" 404 -

推荐答案

您需要注册一个catch-all脚本处理程序。在你的app.yaml的末尾追加这个：

You need to register a catch-all script handler. Append this at the end of your app.yaml:

- url: /.*
  script: main.py

在main.py中，您需要输入以下代码：

In main.py you will need to put this code:

from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app

class NotFoundPageHandler(webapp.RequestHandler):
    def get(self):
        self.error(404)
        self.response.out.write('<Your 404 error html page>')

application = webapp.WSGIApplication([('/.*', NotFoundPageHandler)],
                                     debug=True)

def main():
    run_wsgi_app(application)

if __name__ == "__main__":
    main()

将<您的404错误html页面> 替换为有意义的内容。或者更好地使用模板，您可以阅读此处。

Replace <Your 404 error html page> with something meaningful. Or better use a template, you can read how to do that here.

如果您在设置时遇到问题，请告诉我。

Please let me know if you have problems setting this up.
