MongoDB的getUsers()和SHOW命令是否达到相同的目的？
无论是getUsers()方法和SHOW命令可用于列出在蒙戈壳的所有用户。
情况1-使用getUsers()
语法如下-
db.getUsers();
情况2-使用show命令
语法如下-
show users;
让我们实现这两种语法，以便在MongoShell中列出所有用户。
情况1-第一个查询如下-
> db.getUsers();
以下是输出-
[
{
"_id" : "test.John",
"user" : "John",
"db" : "test",
"roles" : [
{
"role" : "readWrite",
"db" : "test"
},
{
"role" : "dbAdmin",
"db" : "test"
}
],
"mechanisms" : [
"SCRAM-SHA-1",
"SCRAM-SHA-256"
]
},
{
"_id" : "test.admin",
"user" : "admin",
"db" : "test",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
],
"mechanisms" : [
"SCRAM-SHA-1",
"SCRAM-SHA-256"
]
}
]情况2-第二个查询如下-
> show users;
以下是输出-
{
"_id" : "test.John",
"user" : "John",
"db" : "test",
"roles" : [
{
"role" : "readWrite",
"db" : "test"
},
{
"role" : "dbAdmin",
"db" : "test"
}
],
"mechanisms" : [
"SCRAM-SHA-1",
"SCRAM-SHA-256"
]
}
{
"_id" : "test.admin",
"user" : "admin",
"db" : "test",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
],
"mechanisms" : [
"SCRAM-SHA-1",
"SCRAM-SHA-256"
]
}
