如何使用 python 从字符串列表中删除生成的 json 之外的双引号

Question

我的 JSON 是输入 json { 'debug': None, 'traceback': None, 'rsname': None, 'resolutionStatus': 0, 'algorithmResponseInfo': None, 'rules': "['check'], ': '-RNCID Found', 'mmlCommand': 'tk_com', 'KMmmlCommand': 'cat "tk"', 'similarityScore': {'similarityUI': 100 }} 这是无效的，我想将其转换为有效json 我想使用 python 从规则列（列表）中删除""双引号和单反斜杠。 我已经尝试了以下方法，但没有奏效-

data = data.replace('"',"\\'").replace("'", '"').replace("True","true").\
             replace("None","null").replace("False","false").replace("\'", '"').replace("'", '"')

data = json.loads(data)

output is - data = { "debug": null, "traceback": null, "rsname": null, "resolutionStatus": 0, "algorithmResponseInfo": null, "rules": \ "["check"]", " rulesResults": "-RNCID Found", "mmlCommand": "tk_com", "KMmmlCommand": "cat "tk"", "similarityScore": { "similarityUI": 100 }}

but i need to remove extra backshlash and double quotes expected is - data = { "debug": null, "traceback": null, "rsname": null, "resolutionStatus": 0, "algorithmResponseInfo": null, "rules": [“检查”]，“rulesResults”：“找到-RNCID”，“mmlCommand”：“tk_com”，“KMmmlCommand”：“cat“tk””，“similarityScore”：{“similarityUI”：100 }}

您所拥有的根本不是 JSON ，而是 Python 文字。 只是 Python 的字面量与 JSON 非常相似。 转换它的安全方法是使用 ast.literal_eval：

from ast import literal_eval
import json
data = (
    "{ 'debug': None, 'traceback': None, 'rsname': None,"
    " 'resolutionStatus': 0, 'algorithmResponseInfo': None, "
    "'rules': \"['check']\", 'rulesResults': '-RNCID Found', "
    "'mmlCommand': 'tk_com', 'KMmmlCommand': 'cat \"tk\"',"
    " 'similarityScore': {'similarityUI': 100 }}"
python_doc = literal_eval(data)
json_str = json.dumps(python_doc)

# {"debug": null, "traceback": null, "rsname": null, "resolutionStatus": 0,
# "algorithmResponseInfo": null, "rules": "['check']",
#  "rulesResults": "-RNCID Found", "mmlCommand": "tk_com",
#  "KMmmlCommand": "cat \"tk\"", "similarityScore": {"similarityUI": 100}}
print(json_str)

literal_eval的不安全替代方案是eval 。 eval的问题在于，如果攻击者可以控制输入，他们就可以导致任意代码运行。
