Google App Engine self.redirect文章 [英] Google App Engine self.redirect post

问题描述

我有一个表单将信息发布给我的一个处理程序。我的处理程序验证信息，然后需要将这些信息发布给第三方，并将用户重定向到该页面。

的示例

  class ExampleHandler（BaseRequestHandler）：
DocString here ... 

 def post（self） ：
 day = int（self.request.get（'day'））
 checked_day = CheckDay（day）
如果checked_day：
＃这里是我想重定向的地方用户到第三方 - 但通过一个帖子，因为我将代表他们在checked_day基于数据提交表单。 
 else：
＃否则不需要发布重定向 - 只是一个简单的self.redirect。 
 self.redirect（'/ example'）
  

可以将用户重定向到我提交表单的页面？

理想情况下，我希望self.redirect（）允许发布到第三方网站，我相信这是一个选项。

我的目标是在将它们发送给第三方之前检查提供的数据。是他们的其他选项我缺少？

解决方案

您可以张贴表单并将用户重定向到一个页面，但他们会必须是单独的操作。

$ b urlfetch.fetch（）方法可让您将方法设置为POST ：

 导入urllib 
 
 form_fields = {
first_name：Albert， 
last_name：Johnson，
email_address：[e-mail]
} 
 form_data = urllib.urlencode（form_fields）
 header = {'Content-Type'：'application / x-www-form-urlencoded'} 
 result = urlfetch.fetch（url = url，
 payload = form_data，
 method = urlfetch .POST，
 headers = headers）
  

以上例子来自 URL抓取Python API概述。

I have a form that POSTs information to one of my handlers. My handler verifies the information and then needs to POST this information to a third party AND redirect the user to that page.

Example of the

    class ExampleHandler(BaseRequestHandler):
  """DocString here...
  """
  def post(self):
    day = int(self.request.get('day'))
    checked_day = CheckDay(day)
    if checked_day:
      #Here is where I would like to redirect the user to the 3rd party -- but via a post as I will be submitting a form based on data in checked_day on their behalf.
    else:
      # Otherwise no post redirect is needed  -- just a simple self.redirect.
      self.redirect('/example')

Do you have any advice on how I can redirect the user to the page where I have submitted a form?

I would ideally like a self.redirect() that allowed POSTs to 3rd party sites but I don't believe this is an option.

My goal is to check the data provided before sending them along to the 3rd party. Are their other options I am missing?

解决方案

You can POST the form and redirect the user to a page, but they'll have to be separate operations.

The urlfetch.fetch() method lets you set the method to POST like so:

import urllib

form_fields = {
  "first_name": "Albert",
  "last_name": "Johnson",
  "email_address": "[e-mail]"
}
form_data = urllib.urlencode(form_fields)
headers = {'Content-Type': 'application/x-www-form-urlencoded'}
result = urlfetch.fetch(url=url,
                        payload=form_data,
                        method=urlfetch.POST,
                        headers=headers)

The above example is from the URL Fetch Python API Overview.
