logout

logout

Deprecated since version 5.0.自5.0版以来已弃用。

Attempting to use the logout command will write an error message to the log once per logout attempt.尝试使用logout命令将在每次注销尝试时向日志中写入一条错误消息。

This command will be removed in a future release.此命令将在将来的版本中删除。

The logout command terminates the current authenticated session:logout命令终止当前经过身份验证的会话：

{ logout: 1 }

Note注意

If you're not logged in and using authentication, logout has no effect.如果您没有登录并使用身份验证，则logout无效。

Because MongoDB allows users defined in one database to have privileges on another database, you must call logout while using the same database context that you authenticated to.因为MongoDB允许在一个数据库中定义的用户拥有对另一个数据库的权限，所以您必须在使用经过身份验证的同一数据库上下文时调用logout。

If you authenticated to a database such as users or $external, you must issue logout against this database in order to successfully log out.如果您对数据库（如用户或$external）进行了身份验证，则必须对此数据库发出logout命令才能成功注销。

Example实例

Use the use <database-name> helper in mongosh, or the following db.getSiblingDB() method in an interactive mongosh session or in mongosh shell scripts to change the db object:在mongosh中使用<database name>helper，或者在交互式mongosh会话或mongosh shell脚本中使用以下db.getSiblingDB()方法来更改db对象：

db = db.getSiblingDB('<database-name>')

When you have set the database context and db object, you can use the logout to log out of database as in the following operation:设置了数据库上下文和db对象后，可以使用logout注销数据库，如下操作所示：

db.runCommand( { logout: 1 } )
