文档数据库服务 DDS

示例

更新用户信息

products数据库中的用户appClient01，其信息如下：

{
	"_id" : "products.appClient01",
	"token" : NumberLong("8424642624807814713"),
	"user" : "appClient01",
	"db" : "products",
	"customData" : {
		"empID" : "12345",
		"badge" : "9156"
	},
	"roles" : [
		{
			"role" : "readWrite",
			"db" : "products"
		},
		{
			"role" : "read",
			"db" : "inventory"
		}
	],
	"mechanisms" : [
		"SC RAM -SHA-1",
		"SCRAM-SHA-256"
	]
}

下面操作会替换用户的自定义数据和角色数据：

use products
db.updateUser( "appClient01",
{
   customData : { employeeId : "0x3039" },
   roles : [
      { role : "read", db : "assets"  }
   ]
} )

products数据库中的用户appClient01，经过更新后信息如下：

{
	"_id" : "products.appClient01",
	"token" : NumberLong("8424642624807814713"),
	"user" : "appClient01",
	"db" : "products",
	"customData" : {
		"employeeId" : "0x3039"
	},
	"roles" : [
		{
			"role" : "read",
			"db" : "assets"
		}
	],
	"mechanisms" : [
		"SCRAM-SHA-1",
		"SCRAM-SHA-256"
	]
}

更新用户以仅使用SCRAM-SHA-256凭证
reporting数据库中的用户reportUser256，其信息如下：
```
{
	"_id" : "reporting.reportUser256",
	"token" : NumberLong("2827251846225877395"),
	"user" : "reportUser256",
	"db" : "reporting",
	"roles" : [ ],
	"mechanisms" : [
		"SCRAM-SHA-1",
		"SCRAM-SHA-256"
	]
}
```
以下操作会将当前同时拥有 SCRAM-SHA-256 和 SCRAM-SHA-1 全权证书的用户更新为只拥有 SCRAM-SHA-256 全权证书的用户。
- 如果密码未与mechanisms一起指定，则只能将mechanisms更新为用户当前SCRAM机制的子集。
- 如果密码与mechanisms一起指定，则可以指定任何受支持的SCRAM机制。
- 对于SCRAM-SHA-256，passwordDigestor必须是默认值 "server"。
```
db.updateUser(
   "reportUser256",
   {
     mechanisms: [ "SCRAM-SHA-256" ]
   }
)
```
reporting数据库中的用户reportUser256，经过更新后信息如下：
```
{
	"_id" : "reporting.reportUser256",
	"token" : NumberLong("2827251846225877395"),
	"user" : "reportUser256",
	"db" : "reporting",
	"roles" : [ ],
	"mechanisms" : [
		"SCRAM-SHA-256"
	]
}
```
