Python 2.7，Appengine Data Store&统一 [英] Python 2.7, Appengine Data Store & Unicode

问题描述

所以我今天晚上对Unicoding有很多了解，因为我正在考虑切换到Jinja2，这需要Unicode在应用程序中的任何地方使用。我想我对如何处理它有了一个好主意，但是我想在开始编写我的应用程序之前听到这是否合理：

处理外部文本输入（通过html表单）a）确保所有的html页面都是UTF-8编码的。

b）一旦用户按下提交，确保数据一旦python后端收到它就转换为Unicode ... decode（self.request.get（ 'stuff'），utf-8）
c）留在unicode中，将输出转移到Jinja2，它总是使用utf-8的默认编码。

来自appengine数据存储区的信息

lockquote
因为Google将所有内容存储为Unicode，所有来自数据存储区的数据都已经是unicode，我不必担心任何事情（yay！）

应用程序中的字符串

确保所有以u开头（即），这将迫使一切都在unicode。

以上是我保持一致的策略。还有什么我需要考虑的？

谢谢！

解决方案

您不需要.decode self.request.get（'stuff'），utf-8如果使用webapp或webapp2。框架尊重指定的数据输入类型。

其他看起来是正确的。

另外，我相信__future__中的

  import unicode_strings 
  

应该是

  from __future__ import unicode_literals 
  

仅适用于2.6和2.7所以在App Engine它只有在使用2.7
时才可用

So I've been reading quite a bit about Unicoding tonight because I was thinking of switching to Jinja2, which requires Unicode to be used everywhere within the app. I think I have a good idea of how to deal with it, but I wanted to hear if this is reasonable before I started to code my app:

1. Dealing with External Text-Inputs (via html forms)

   a) Make sure all html pages are utf-8 encoded.
   b) Once users press submit, make sure the data is converted into Unicode as soon as the python backend receives it...decode(self.request.get('stuff'),utf-8)
   c) Stay in unicode, transfer the outputs to Jinja2 which will always it using the default encoding of utf-8.

2. Information from the appengine datastore

   Because google stores everything as Unicode, all data coming in from the datastore is already unicode and I don't have to worry about anything (yay!)

3. Strings within the app

   Make sure all "" start with a u (i.e. u"hello world"), this will force everything to be in unicode.

Well the above is my strategy to keep everything consistent. Is there anything else I need to account for?

thanks!

解决方案

You should not need to .decode(self.request.get('stuff'),utf-8 if you using webapp or webapp2. The framework respects the input type of the data as specified.

Everything else looks right.

Also I believe that

from __future__ import unicode_strings

should be

from __future__ import unicode_literals

and is only available in 2.6 and 2.7 So in App Engine it would only be available if you are using 2.7
