如何按名字对这个 JSON 对象进行排序？

{
    1  :{user_id:1, first_name:"first_name1", last_name:"lastname1", email:"user1@test.com"},
    7  :{user_id:7, first_name:"user2", last_name:"test2", email:""}, 
    72 :{user_id:72, first_name:"testing343", last_name:"", email:""},
    246:{user_id:246, first_name:"aaa", last_name:"ssss", email:""}
}
