如何编码python字典？ [英] How to encode python dictionary?

问题描述

我想编码下面显示的示例内容：

I want to encode the sample stuff shown below:

name = "Myname"
status = "married"
sex = "Male"
color = {'eyeColor' : 'brown', 'hairColor' : 'golden', 'skinColor' : 'white'}

我正在使用base64编码方案，并将语法用作< field-name> .encode（'base64'，'严格的'）其中字段名称由上述字段组成，名称，状态等。

I am using base64 encoding scheme and used syntax as <field-name>.encode('base64','strict') where field-name consists of above mentioned fields- name, status and so on.

除字典color之外的所有内容都被编码。
我在 color.encode（'base64'，'strict'）中得到错误

Everything except dictionary "color" is getting encoded. I get error at color.encode('base64','strict')

错误如下所示：

Traceback (most recent call last):
    color.encode('base64','strict') 
AttributeError: 'CaseInsensitiveDict' object has no attribute 'encode'

我认为编码方法不适用于字典。
我将如何一次编码完整的字典？
是否有替代 encode 方法适用于字典？

I think encode method is not appicable on dictionary. How shall I encode the complete dictionary at once? Is there any alternative to encode method which is applicable on dictionaries?

推荐答案

encode 是字符串实例具有的方法，而不是字典。您不能简单地将其与每个对象的每个实例一起使用。
所以最简单的解决方案是首先在字典上调用 str ：

encode is a method that string instances has, not dictionaries. You can't simply use it with every instance of every object. So the simplest solution would be to call str on the dictionary first:

str(color).encode('base64','strict')

当您想要解码字符串并将该字典恢复时，这不太直接。 Python有一个模块来做到这一点，它被称为泡菜。 Pickle可以帮助您获取任何对象的字符串表示，然后可以将其编码为base64。解码之后，您也可以取消打包以取回原始实例。

However, this is less straight forward when you'd want to decode your string and get that dictionary back. Python has a module to do that, it's called pickle. Pickle can help you get a string representation of any object, which you can then encode to base64. After you decode it back, you can also unpickle it to get back the original instance.

b64_color = pickle.dumps(color).encode('base64', 'strict')
color = pickle.loads(b64_color.decode('base64', 'strict'))

其他pickle + base64的替代方法可能是 json 。

Other alternatives to pickle + base64 might be json.
