无法对pprint输出进行编码/解码 [英] Unable to encode/decode pprint output

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 文件都有＃ - * - 编码：utf-8 - * - 编码定义在第一行，像我的 api.py

My .py files are all have # -*- coding: utf-8 -*- encoding definer on the first line, like my api.py

正如我提到的相关问题，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')

一切都OK，当我打电话给我的API服务时，除了字符串之外，没有编码问题由pprint编写的字典

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中使用了一些值中的土耳其字符，所以pprint将它们转换为 unichr 等价物，如：

Since I am using Turkish characters in some values in my dict, pprint converts them to unichr equivalents, like:

API_STATUS = {
    1: 'müşteri',
    2: 'some other status message'
}

my_str = 'Here is the documentation part that contains Turkish chars like işüğçö'
my_str += pprint.pformat(API_STATUS, indent=4, width=1)
return HttpRespopnse(my_str, content_type='text/plain; charset=utf-8')

我的纯文本输出如下：

Here is the documentation part that contains Turkish chars like işüğçö

{
    1: 'm\xc3\xbc\xc5\x9fteri',
    2: 'some other status message'
}

我尝试将pprint输出解码或编码为不同的编码，没有成功...克服这个问题的最佳做法是什么

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 似乎使用 repr 默认情况下，您可以通过覆盖 PrettyPrinter来解决此问题。格式 ：

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'işüğçö'}

pprint.pprint(d)              # {'foo': u'i\u015f\xfc\u011f\xe7\xf6'}
MyPrettyPrinter().pprint(d)   # {'foo': işüğçö}
