原因在于：字符串里用单引号来标识字符。
解决办法如下：将字符串里的单引号替换成双引号
1 >>> import re 2 >>> test=re.sub(‘\‘‘,‘\"‘,test) 3 >>> result=json.loads(test) 4 >>> result[‘data‘] 5 ‘123‘
对于带u‘的字符串，u也要去掉：
1 >>> c=f.read() 2 >>> c 3 "{u‘meta‘: {u‘code‘: 200, u‘requestId‘: u‘5815f6739fb6b77494061e19‘}, u‘response 4 ‘: {u‘tips‘: {u‘count‘: 0, u‘items‘: []}}}" 5 >>> d=re.sub("u‘","\"",c) 6 >>> d 7 ‘{"meta\‘: {"code\‘: 200, "requestId\‘: "5815f6739fb6b77494061e19\‘}, "response\ 8 ‘: {"tips\‘: {"count\‘: 0, "items\‘: []}}}‘ 9 >>> d=re.sub("‘","\"",d) 10 >>> d 11 ‘{"meta": {"code": 200, "requestId": "5815f6739fb6b77494061e19"}, "response": {" 12 tips": {"count": 0, "items": []}}}‘ 13 >>> json.loads(d) 14 {‘response‘: {‘tips‘: {‘items‘: [], ‘count‘: 0}}, ‘meta‘: {‘requestId‘: ‘5815f67 15 39fb6b77494061e19‘, ‘code‘: 200}}
python基础：json.loads(str)出现错误总结
