消除JSON文档中键值的前导和尾随反冲 [英] removing leading and trailing backlash in key value in JSON documents

问题描述

我具有以下JSON结构.

I have the following JSON structure.

"bent": "{
       \"ActiveT\": 6,
        \"ErrorM\": \"None\",
        \"Except\": \"None\",
        \"HadErr\": \"false\",
        \"HM\": 62,
        \"NHM\": 57,
        \"Parameter\": \"14331232706\",
        \"ReturnCode\": \"3050\",
        \"Severity\": \"info\",
        \"Timestamp\": \"Tue July0209: 58: 16NZST2015\",
        \"TId\": \"9891319709\",
        \"UserInfo\": \"Unknown\",
    }"

我想在JSON结构中的每个key和value的开头和结尾处删除\，我想使用python正则表达式来做到这一点.

I want to remove the \ at the beginning and the end of each of the key and value in the JSON structure.I want to do this using python regular expressions.

推荐答案

使用 re.sub

>>> print re.sub(r'\\(?=")', '', string)
"bent": "{
       "ActiveT": 6,
        "ErrorM": "None",
        "Except": "None",
        "HadErr": "false",
        "HM": 62,
        "NHM": 57,
        "Parameter": "14331232706",
        "ReturnCode": "3050",
        "Severity": "info",
        "Timestamp": "Tue July0209: 58: 16NZST2015",
        "TId": "9891319709",
        "UserInfo": "Unknown",
    }

正则表达式说明

• \\匹配\

(?=")积极向前看.检查\之后是否是"

(?=") Positive look ahead. Checks if the \ is followed by "

将其替换为空字符串.

OR

使用 string.replace

>>> print string.replace('\\"', '"')
"bent": "{
       "ActiveT": 6,
        "ErrorM": "None",
        "Except": "None",
        "HadErr": "false",
        "HM": 62,
        "NHM": 57,
        "Parameter": "14331232706",
        "ReturnCode": "3050",
        "Severity": "info",
        "Timestamp": "Tue July0209: 58: 16NZST2015",
        "TId": "9891319709",
        "UserInfo": "Unknown",
    }
