阻止對HTTP上的robots.txt的訪問，在app.yaml

Question

我需要在robots.txt上提升404 Not Found，而從HTTP訪問時，在HTTPS上robots.txt應該正常返回。

我找不到僅限制在app.yaml配置訪問到https的方式，所以我決定寫一個處理程序，卻得到了以下錯誤：

google.appengine.api.yaml_errors.EventError: Unexpected attribute "script" for mapping type static_files.  

在app.yaml我：

- url: /robots.txt 
    script: main.application 
    static_files: static/\1 
    upload: static/robots.txt 

處理這種情況的最佳方法是什麼？

Answer 1

簡單的處理就可以了：

的app.yaml

- url: /robots_file 
    static_files: static/robots.txt 
    upload: static/robots.txt 

views.py：

from google.appengine.api.urlfetch import fetch 

class RobotsTxtHandler(webapp2.RequestHandler): 

    def get(self): 
     if self.request.url.startswith('https'): 
      robots = fetch('{}/robots_file'.format(SITE_URL)) 
      return self.response.write(robots.content) 
    raise errors.Http404 

urls.py：

urls = [ 
    ('/robots.txt', views.RobotsTxtHandler), 
]

設置secure: always的應用程序。 yaml爲你處理。

文檔：https://cloud.google.com/appengine/docs/standard/python/config/appref

secure: always - Requests for a URL that match this handler that do not use HTTPS are automatically redirected to the HTTPS URL with the same path. Query parameters are preserved for the redirect.

你的情況：

- url: /robots.txt 
    static_files: static/robots.txt 
    upload: static/robots.txt 
    secure: always
