Example示例
The accountUser01 user in the products database has the following roles:products数据库中的accountUser01用户具有以下角色:
"roles" : [
{ "role" : "assetsReader",
"db" : "assets"
},
{ "role" : "read",
"db" : "stock"
},
{ "role" : "readWrite",
"db" : "products"
}

use products
db.revokeRolesFromUser( "accountUser01",
[ { role: "read", db: "stock" }, "readWrite" ],
{ w: "majority" }
)
The user accountUser01 user in the products database now has only one remaining role:products数据库中的用户accountUser01用户现在只剩下一个角色:
"roles" : [
{ "role" : "assetsReader",
"db" : "assets"
}
]
