尝试将数据从txt文件加载到请求的变量中

Question

with open('data.txt', 'r') as file:
     dat2 = file.read()

post2 = {
        "id": 5,
        "method": "set",
        "params": [
            {
                "data": [
                     dat2
                    ],
                "url": "/config/url"
            },
            ]
        "session": sessionkey,
        "verbose": 1
        }

File "C:\Users\user\AppData\Local\Programs\Python\Python37\lib\json\__init__.py", line 296, in load
    parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw)
  File "C:\Users\user\AppData\Local\Programs\Python\Python37\lib\json\__init__.py", line 348, in loads
    return _default_decoder.decode(s)
  File "C:\Users\user\AppData\Local\Programs\Python\Python37\lib\json\decoder.py", line 340, in decode
    raise JSONDecodeError("Extra data", s, end)
json.decoder.JSONDecodeError: Extra data: line 2 column 18 (char 145)

Answer 1

删除尾随的撇号，并将词典放在文件中的列表中，应该如下所示：

[{"name": "Host1","type": "ipmask","subnet": ["0.0.0.0","255.255.255.255"],"dynamic_mapping": null}, {"name": "Host2","type": "ipmask","subnet": ["0.0.0.0","255.255.255.255"],"dynamic_mapping": null}]

然后使用json.loads将其转换为列表：

with open('data.txt', 'r') as file:
     dat2 = file.read()

import json
post2 = {"data": json.loads(dat2)}

这将使post2

{'data': [{'name': 'Host1', 'type': 'ipmask', 'subnet': ['0.0.0.0', '255.255.255.255'], 'dynamic_mapping': None}, {'name': 'Host2', 'type': 'ipmask', 'subnet': ['0.0.0.0', '255.255.255.255'], 'dynamic_mapping': None}]}
