python在长字符串中提取想要的数据

Question

数据库返回以下格式信息：
{"PERFORMANCE_CHECK":"true","username":"[e-mail]","model":"1","security.check":"true","security.a":"true","security.hosts":"1.1.1.1","security.referer":"https://ask.csdn.net/new?word=,https://mp.csdn.net/mp_others/manage/answer?switch=1&status=all%22,%22server.http%22:%22%22,%22httpMethods%22:%22POST,GET%22,%22resume%22:%22true%22,%22validate%22:%22true%22,%22check%22:%22false%22,%22url%22:%22%22,%22check%22:%22true%22,%22.lsycheck%22:%22true%22,%22updateStatus%22:%222021-12-17 16:34:14"}

现在期望提取各自参数对应的值，如检查PERFORMANCE_CHECK是否等于true，提取username的值='[e-mail]'，
并输出展示例如：
PERFORMANCE_CHECK : true
username : [e-mail]
……

请问处理思路是什么

解决了，用json格式化，忘了这是个json格式了
