字符串：
[{"forum_id":352902,"forum_name":"pt","is_sign_in":1,"level_id":11,"cont_sign_num":536,"loyalty_score":{"normal_score":4,"high_score":14}},{"forum_id":1996261,"forum_name":"固态硬盘","is_sign_in":1,"level_id":11,"cont_sign_num":536,"loyalty_score":{"normal_score":4,"high_score":14}}]

想匹配四个数字：“11”“536”“11”“536”，请问怎样写？谢谢大佬们！

添加变量分别是

"level_id":(.+?),
"cont_sign_num":(.+?),
