Question

在Python中 Websocket这样给我字符串：

'{"type":"done","sequence":49109868,"time":"2015-04-06T17:57:00.86877Z"}'

我想将此字符串转换为表格：

{"type":"done","sequence":49109868,"time":"2015-04-06T17:57:00.86877Z"}

似乎唯一的区别是开头和结尾的撇号。有关如何做到这一点的任何想法？

Answer 1

import json

def StringToJson(string):

    # [1:-1] Assuming you only want to remove the quotes at either end. Strip()           
    #because there might after all be some whitespace present.

    return json.loads(string.strip()[1:-1])


string = """'{"type":"done","sequence":49109868,"time":"2015-04-06T17:57:00.86877Z"}'""" 

table = StringToJson(string)

如果上述解决方案不起作用，可能只是您认为存在的引号只是您获得的错误消息的一部分。您可以尝试以下方法：

import json

parsedString  = json.loads(string) # Where string is the text you're trying to access the keys of.

Answer 2

import ast
ast.literal_eval('{"type":"done","sequence":49109868,"time":"2015-04-06T17:57:00.86877Z"}')

Answer 3

看起来你正在获得一个json对象。您可以使用内置于json转换器中的python将其转换为python dict。

import json
t = json.loads('{"type":"done","sequence":49109868,"time":"2015-04-06T17:57:00.86877Z"}')

t现在将成为具有这些键/值对的字典
