我正在学习 Django。有一个搜索栏。这旨在与俄语单词一起使用。这个词被一个简单的形式抓住了。

如何在开头将单词编码为 utf-8？因此，它会在某个时候创建​​ UnicodeEncodeError。或者有什么方法可以改变原来的请求？

数据库设置为 utf-8。

谢谢你。

这是回溯

我对此没有太多经验，但根据Jonathan “Wolf” Rentzsch 的在 web 上使用 UTF-8 的指南，您可能想尝试将accept-charset="UTF-8"属性添加到您的<form>标签中。

你在哪里看的UnicodeEncodeError？你能给我们看一些代码吗？

编辑：啊，好吧。是的——我认为Django 将所有文本都提供为 Unicode 对象。如果我正确理解了回溯，那么当您调用str此 unicode 对象以将其与urllib.quote_plus.

我认为您需要提供urllib.quote_plus以 ASCII 编码的文本（请参阅是否有可用于 Python 2.6.5 中的 urllib.quote 和 urllib.unquote 的 unicode-ready 替代品？）。

根据这个问题，我认为你可以这样做：

import unicodedata
v_as_ascii = unicodedata.normalize('NFKD', v.decode('UTF-8')).encode('ascii', 'ignore')
v = quote_plus( v_as_ascii )

（不过我还没有测试过这些，所以我可能完全错了。希望有这方面经验的人能过来。）
