python - 值错误: Invalid\escape unable to load json from file

Question

我在 python 中加载用户和密码的 json 文件以从其余 api 检索数据时遇到问题，该 api 使用身份验证从 url 中提取 json 数据。

当我将用户、密码和 uri 放入 json 文件并运行脚本时，它在 json 库中给出此错误:

Traceback (most recent call last):
  File "C:/Python27/Script.py", line 10, in <module>
    config = json.load(config_file) 
  File "C:\Python27\lib\json\__init__.py", line 290, in load
    parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw)
  File "C:\Python27\lib\json\__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "C:\Python27\lib\json\decoder.py", line 364, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Python27\lib\json\decoder.py", line 380, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Invalid \escape: line 7 column 42 (char 270)

这是代码:

import urllib2
import json

 #Load the config file
with open('Config.json') as config_file :    
    config = json.load(config_file) 
# Load your username from the config file
user = config['user']
# Load your password from the config file
password = config['password']

enter code here

从中加载示例的 json 文件位于此处:

{
    "user" : "api",
    "password" : "admin1234",
    "uri": "https://datafeeds.emailsecurity.com/test",
    "resetUri": "https://datafeeds.emailsecurity.com/test/test?reset=2017-07-01T00:00:00Z",
    "files" : {
        "cookiesFilePath" : "C:\\abc",
        "logsFilePath" : "C:\\abc",
    }
}

正如其他人所说，问题是双反斜杠。您想要转义两个反斜杠，例如:

bad_str = '{"a" : "C:\\ b"}'
good_str = '{"a" : "C:\\\\ b"}'

#JSONDecodeError
print(json.loads(bad_str))

# OK
print(json.loads(good_str))
