Python3 无法将字符串转换为 dict 或 json

Question

r = requests.get(http_get_url, headers=headers)
r = r.text
r = r.replace("true", "True")
z = json.loads(r)

但是，我没有加载 json (或 python 字典)，而是得到:

Traceback (most recent call last):
  File "/home/noir/PycharmProjects/Work_Projects/get_errors.py", line 21, in <module>
    get_errors(id)
  File "/home/noir/PycharmProjects/Work_Projects/get_errors.py", line 17, in get_errors
    z = json.loads(r)
  File "/usr/lib/python3.6/json/__init__.py", line 354, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.6/json/decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python3.6/json/decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 2 column 26 (char 28)

print(type(r))的结果是 <class 'str'>

以及 print(r) 的输出将“true”转换为“True”后为:

{
    "HasItemsWithCount": True,
    "Collection": [

            {
            "GroupId" : "14",
            "Time" : "5/16/18, 5:02 PM",
            "File" : "[ESCAPE[]]",
            "Message" : "[ESCAPE[Client was restarted during backup, session may be incomplete.]]",
            "Count" : "3"
            },

    ]
}

所以我无法理解为什么格式正确的r字符串无法导入到json中。

此外，如果我获取此输出并通过复制/粘贴将其直接写入 python，则变量的类型为 dict，这表明文本的格式对于 Python 中的 dict 来说是正确的。所以我不确定为什么 json.loads 失败。

您的替换是向后的:

而不是:

r = r.replace("true", "True")

尝试:

r = r.replace("True", "true")
