revokeRolesFromRole¶

Definition定义¶

revokeRolesFromRole¶

Removes the specified inherited roles from a role. The revokeRolesFromRole command has the following syntax:语法如下所示：

{ revokeRolesFromRole: "<role>",
  roles: [
    { role: "<role>", db: "<database>" } | "<role>",
    ...
  ],
  writeConcern: { <write concern> },
  comment: <any>
}

The command has the following fields:

Field字段	Type类型	Description描述
revokeRolesFromRole	string	The role from which to remove inherited roles.
roles	array	The inherited roles to remove.
writeConcern	document	Optional.可选。The level of write concern to apply to this operation. The writeConcern document uses the same fields as the getLastError command.
comment	any	Optional.可选。A user-provided comment to attach to this command. Once set, this comment appears alongside records of this command in the following locations: mongod log messages, in the attr.command.cursor.comment field. Database profiler output, in the command.comment field. currentOp output, in the command.comment field. A comment can be any valid BSON type (string, integer, object, array, etc). New in version 4.4.版本4.4中的新功能。

In the roles field, you can specify both built-in roles and user-defined roles.

To specify a role that exists in the same database where revokeRolesFromRole runs, you can either specify the role with the name of the role:

"readWrite"

Or you can specify the role with a document, as in:

{ role: "<role>", db: "<database>" }

To specify a role that exists in a different database, specify the role with a document.

Required Access¶

You must have the revokeRole action on a database to revoke a role on that database.

Example示例¶

The purchaseAgents role in the emea database inherits privileges from several other roles, as listed in the roles array:

{
   "_id" : "emea.purchaseAgents",
   "role" : "purchaseAgents",
   "db" : "emea",
   "privileges" : [],
   "roles" : [
      {
         "role" : "readOrdersCollection",
         "db" : "emea"
      },
      {
         "role" : "readAccountsCollection",
         "db" : "emea"
      },
      {
         "role" : "writeOrdersCollection",
         "db" : "emea"
      }
   ]
}

The following revokeRolesFromRole operation on the emea database removes two roles from the purchaseAgents role:

use emea
db.runCommand( { revokeRolesFromRole: "purchaseAgents",
                 roles: [
                          "writeOrdersCollection",
                          "readOrdersCollection"
                        ],
                  writeConcern: { w: "majority" , wtimeout: 5000 }
             } )

The purchaseAgents role now contains just one role:

{
   "_id" : "emea.purchaseAgents",
   "role" : "purchaseAgents",
   "db" : "emea",
   "privileges" : [],
   "roles" : [
      {
         "role" : "readAccountsCollection",
         "db" : "emea"
      }
   ]
}
