升级到django rest framework 3后出现UnicodeDecodeError

在django rest框架2下，以下功能可以正常工作：

from rest_framework import rest_response, generics
from rest_framework.renderers import JSONRenderer, BrowsableAPIRenderer

class SomeView(generics.GenericAPIView):
    renderer_classes = JSONRenderer, BrowsableAPIRenderer

    def get(self, request, *args, **kwargs):
        ... 
        # Build a response dict with non-ascii in it
        ...
        return rest_response.Response(some_dict_with_non_ascii_in_it_somewhere)

我没有显式编码任何非ascii

但是，升级到DRF 3后，相同的代码现在会抛出以下错误：

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 671: ordinal not in range(128)

我猜DRF3现在有了一些新的配置值，在某些地方，这是DRF2下的默认值。我已经尝试将REST\u FRAMEWORK

UNICODE\u JSON

设置为

True

，但仍然得到相同的错误

---

是否有一个设置可以使该部件像DRF2那样工作？或者DRF 3需要我在字典中搜索非ASCII字符并手动编码它？默认情况下Python 2.7认为字符串是二进制的。 尝试在文件顶部添加：

from __future__ import unicode_literals

这将使您的字符串默认为unicode，并有助于正确转换它们。

我找到了答案

在DRF2中，

rest\u framework.JSONRenderer。确保将\u ascii

设置为

True

。在DRF 3中，

rest\u framework.JSONRenderer。确保将\u ascii

设置为

not api\u settings.UNICODE\u JSON

（我在前面写问题时错过了

not

）

因此，为了让它像DRF2一样工作，我需要将“UNICODE_JSON”设置为

False

，而不是

True

，就像我以前尝试过的那样（默认情况下为True）：

---

或者，我当然可以对字典中的值进行编码，这在很多情况下可能是更好的选择。

谢谢。我尝试了一下，虽然它确实做到了所有相关字符串现在都是dict中的unicode，但处理响应对象并将dict转换为字符串的库代码没有那个import语句，所以在执行

'.join（）

…之前，东西会被转换回unicode和常规字符串的混合体。。。

REST_FRAMEWORK = {
    ...
    'UNICODE_JSON': False
}
