python json转dict遇ValueError: Expecting property name问题

代码：
        with open(yamlOutPath) as fr:
                content = ''
                for line in fr.readlines():
                        content = content + line
               
                reRes = r'(ok):\s+\[([1-9][0-9]{0,2}\.[1-9][0-9]{0,2}\.[1-9][0-9]{0,2}\.[1-9][0-9]{0,2})\]\s+=\>\s+({.*?})'
                resList = re.findall(reRes, str(content), flags = re.S + re.M)
                resListLen = len(resList)
               
                if resListLen > 0:
                        for iRes in range(resListLen):
                                print('status: %s' %resList[iRes][0])
                                print('ip: %s' %resList[iRes][1])
                                print('msg: %s' %resList[iRes][2])
                               
                                msg = resList[iRes][2].replace('\r\n', '')
                                msg = re.sub(r'\s+"', '"', msg)
                                print('msg type: %s' %type(msg))
                                print('msg pro: %s' %msg)
                                print(json.loads(msg))

                else:
                        print('No content match')
执行结果：

ValueError: Expecting property name: line 1 column 2 (char 1)

我的json字符串格式应该是没问题的，为什么json.loads()会报上述错误呢，麻烦大家帮帮我，谢谢大家

找到问题所在了，因为字符串中存在控制字符，所以一直报ValueError: Expecting property name: line 1 column 2 (char 1)，终究json字符串格式存在问题，删除字符串中的控制字符就可以了
