Question

我只是想从我正在生成的哈希列表中生成一些JSON。这是列表中每个对象的样子：

{ 'name': unicode(name) }

以下是我如何序列化它：

import simplejson as json

return HttpResponse(LazyEncoder().encode(output_list, ensure_ascii=False), mimetype="application/json")

class LazyEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, Promise):
            return force_unicode(obj)
        return super(LazyEncoder, self).default(obj)

建议使用这个懒惰的编码器by the Django docs here.

这是我得到的错误：

UnicodeDecodeError at /territories
'ascii' codec can't decode byte 0xc3 in position 4: ordinal not in range(128)

为什么它尝试编码为ascii，即使我明确地问它不？

Answer 1

试试mimetype='application/json; charset=utf-8'。也许它很开心。

Answer 2

出于某种原因，当我在字符串周围删除对unicode()的调用时，它有效。无论如何，只要它有效：）

带有JSON的UnicodeDecodeError
