Python UnicodeDecodeError的最佳做法 [英] Best Practices for Python UnicodeDecodeError

问题描述

我使用基于Web的应用程序的 Pylons 框架， Mako 模板。 Python处理unicode字符串的方式并不困难，当我看到我的网站崩溃时，我已经紧张的时刻，当页面被渲染后，我后来才知道它与 UnicodeDecodeError 。

I use Pylons framework, Mako template for a web based application. I wasn't really bother too deep into the way Python handles the unicode strings. I had tense moment when I did see my site crash when the page is rendered and later I came to know that it was related to UnicodeDecodeError.

看到错误后，我开始围绕我的Python代码添加编码，解码使用'ignore'选项的字符串调用，但仍然看不到错误有时候。

After seeing the error, I started mesh around my Python code adding encode, decode calls for string with 'ignore' option but still I could not see the errors gone sometime.

最后，我用来忽略ascii解码，使网站运行没有任何崩溃。

Finally I used to decode to ascii with ignore and made the site running without any crash.

输入到我的网站通过许多网站。这意味着我不会控制选择的语言或语言。我的网站支持国际语言和英语。我有一个feed汇编，一般不用麻烦unicode / ascii / utf-8。当我通过mako模板显示文本时，我显示为原样。

Input to my site comes through many sites. This means that I do not control the languages or language of choice. My site supports international languages and along with English. I have feed aggregation which generally not bother about unicode/ascii/utf-8. While I display the text through mako template, I display as it is.

不是网络专家，在Python项目中处理字符串的最佳做法是什么？我应该只在渲染文本时关心或应用程序的所有阶段？

Not being a web expert, what are the best practices to handle the strings within the Python project? Should I care only while rendering the text or all the phase of the application?

推荐答案

如果您有影响，这是无痛的方式：

If you have influence on it, this is the painless way:

• 尽快知道您的输入编码（或忽略解码）和 decode（encoding）因为它触及你的应用程序


• 内部仅使用unicode（ u'something'是unicode），也在数据库中


• 用于渲染，导出等，随时离开您的应用程序， encode（'utf-8'）数据

• know your input encoding (or decode with ignore) and decode(encoding) the data as soon as it hits your app
• work internally only with unicode (u'something' is unicode), also in the database
• for rendering, export etc, anytime it leaves your app, encode('utf-8') the data
