Question

我正在尝试使用json.loads（）函数将sttr数据类型转换为python中的dict。但是我得到的错误是：

File "/usr/local/lib/python2.7/json/__init__.py", line 339, in loads
    return _default_decoder.decode(s)
  File "/usr/l`enter code here`ocal/lib/python2.7/json/decoder.py", line 364, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/local/lib/python2.7/json/decoder.py", line 380, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)

Answer 1

在注释中，您给出了要作为JSON加载的文本的以下示例：

[
  {
    'entity_class': 'Hardware Entities (AHV)',
    'status': 'recommended',
    'uuid': 'de74178a-cbc7-4c69-ae2f-9e7042bf8e98', 
    'zprotobuf': 'eNolzD1LAzEYB/DFScHBRXAKoUMr5khiLi/dCgpdCg7qIiLPJU/KQS4nyeEL6ne3p+vv/3K8CGiUMBaY77xhymvHAGVkDg1XsosWnT1bcI42tqZlwbWOqWAis5oD08J3VinOOwMXp', 
    'version': '2.4-1542668003', 
    'dependencies': '[{"entity_class": "Dell Update Manager", "version": "1.8-0.112", "exact": "false", "entity_model": "PT Agent on AHV (el6)"}]', 
    'entity_uuid': '00e8f575-d959-4d7f-860a-61cb84400b7a', 
    'order': 4,
  }
]

JSON应该使用双引号，而不是单引号。上面看起来像本机python数据结构语法。这是从本地python到JSON的转储内容。

import json

native_python_data = [
  {
    'entity_class': 'Hardware Entities (AHV)',
    'status': 'recommended',
    'uuid': 'de74178a-cbc7-4c69-ae2f-9e7042bf8e98', 
    'zprotobuf': 'eNolzD1LAzEYB/DFScHBRXAKoUMr5khiLi/dCgpdCg7qIiLPJU/KQS4nyeEL6ne3p+vv/3K8CGiUMBaY77xhymvHAGVkDg1XsosWnT1bcI42tqZlwbWOqWAis5oD08J3VinOOwMXp', 
    'version': '2.4-1542668003', 
    'dependencies': [
        {
            "entity_class": "Dell Update Manager", 
            "version": "1.8-0.112", 
            "exact": "false", 
            "entity_model": "PT Agent on AHV (el6)"
        }
    ], 
    'entity_uuid': '00e8f575-d959-4d7f-860a-61cb84400b7a', 
    'order': 4,
  }
]

json_string_with_escaping = json.dumps(js, indent=4)
print json_string_with_escaping

json.loads（）给出“ ValueError：预期属性名称：”
