字符串模板如何截取或是转换类型

[BadMan008]

"commonAnnotations": {
"alerting_rule_type": "vmp/PromQL",
"alerting_rule_query": "{"AlertingID":"0445bd68-a6d4-a504e5852b34","PromQL":"1 - (es_fs_path_available_bytes{cluster=\\"control-plane-cluster\\"} / es_fs_path_total_bytes{cluster=\\"control-plane-cluster\\"})\\n","WorkspaceID":"c4ca4238a0dcc509a6f75849b"}",
"alerting_rule_levels": "[{"AlertingRuleID":"0445bd68-a6d4-a504e5852b34","Level":"P1","For":"0s","Comparator":"\\u003e","Threshold":0.5}]"
}

标签commonAnnotations.__alerting_rule_query__是 json 格式的字符串，没办法commonAnnotations.alerting_rule_query.AlertingID提取到自字段值。
请问有没有办法进行字符串转 json，进行commonAnnotations.__alerting_rule_query__值的拆分
