从字符串 python 中提取 table

Question

在Python Websocket 给我这样的字符串：

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

我想将此字符串转换为 table:

{"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。关于如何做到这一点有什么想法吗？

Answer 1

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

Answer 2

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，可能只是因为您认为存在的引号只是您收到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 3

您似乎要返回一个 json 对象。您可以使用 python 内置的 json 转换器将其转换为 python 字典。

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

t 现在将成为那些 key/value 对

的字典
