当CLIENT或用户在KEYCLOAK中成功登录后，会返回JWT字符串，其中默认含有权限的信息，但此信息以内嵌的方式呈现，非常不方便。
"resource_access": {
"app-springboot-confidential": {
"roles": [
"user"
]
},
"test-employee-service": {
"roles": [
"READ_EMPLOYEE"
]
},
"service-springboot": {
"roles": [
"READ_PRODUCTS"
]
},
"account": {
"roles": [
"manage-account",
"manage-account-links"
]
},
"test-department-service": {
"roles": [
"READ_DEPARTMENT"
]
}
}
- 需要将权限的信息输出到一个KEY中，这时可以新增自定义CLIENT SCOPE。Mapper中新增KEYCLOAK已内置的【realm roles/client roles】，定义输出到JTW的字段名：my-roles。
- 授权哪些CLIENT可以读取此CLIENT SCOPE.
- 在登录参数scope中，加入此值：my-roles，这样在输出的JWT就会以平面的方式输出所有roles
"my-roles": [
"user",
"READ_EMPLOYEE",
"READ_PRODUCTS",
"manage-account",
"manage-account-links",
"READ_DEPARTMENT",
"offline_access",
"user"
]
