问题描述
这个问题是基于那个的副作用.
This question is based on a side-effect of that one.
我的 .py 文件在第一行都有 # -*- coding: utf-8 -*- 编码定义器,就像我的 api.py
My .py files are all have # -*- coding: utf-8 -*- encoding definer on the first line, like my api.py
正如我在相关问题中提到的,我使用 HttpResponse 返回 api 文档.由于我通过以下方式定义编码:
As I mention on the related question, I use HttpResponse to return the api documentation. Since I defined encoding by:
HttpResponse(cy_content, content_type='text/plain; charset=utf-8')
一切正常,当我调用我的 API 服务时,除了 pprint 从字典中形成的字符串之外,没有任何编码问题
Everything is ok, and when I call my API service, there are no encoding problems except the string formed from a dictionary by pprint
由于我在我的 dict 的某些值中使用土耳其语字符,pprint 将它们转换为 unichr 等价物,例如:
Since I am using Turkish characters in some values in my dict, pprint converts them to unichr equivalents, like:
API_STATUS = { 1: 'mü?teri', 2: 'some other status message' } my_str = 'Here is the documentation part that contains Turkish chars like i?ü???' my_str += pprint.pformat(API_STATUS, indent=4, width=1) return HttpRespopnse(my_str, content_type='text/plain; charset=utf-8')
而我的纯文本输出是这样的:
And my plain text output is like:
Here is the documentation part that contains Turkish chars like i?ü??? { 1: 'mxc3xbcxc5x9fteri', 2: 'some other status message' }
我尝试将 pprint 输出解码或编码为不同的编码,但没有成功......克服这个问题的最佳实践是什么
I try to decode or encode pprint output to different encodings, with no success... What is the best practice to overcome this problem
推荐答案
pprint 似乎默认使用 repr,您可以通过覆盖 PrettyPrinter.format:
pprint appears to use repr by default, you can work around this by overriding PrettyPrinter.format:
# coding=utf8 import pprint class MyPrettyPrinter(pprint.PrettyPrinter): def format(self, object, context, maxlevels, level): if isinstance(object, unicode): return (object.encode('utf8'), True, False) return pprint.PrettyPrinter.format(self, object, context, maxlevels, level) d = {'foo': u'i?ü???'} pprint.pprint(d) # {'foo': u'iu015fxfcu011fxe7xf6'} MyPrettyPrinter().pprint(d) # {'foo': i?ü???}
