创建数据库

功能介绍

创建云数据库 GaussDB(for MySQL)实例数据库。

调用方法

请参见如何调用API

URI

POST /v3/{project_id}/instances/{instance_id}/databases

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

租户在某一Region下的project ID。

获取方法请参见获取项目ID

instance_id

String

实例ID,严格匹配UUID规则。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

通过调用IAM服务获取用户Token接口获取。

请求响应成功后在响应消息头中包含的“X-Subject-Token”的值即为Token值。

X-Language

String

请求语言类型。默认en-us。

取值范围:

  • en-us

  • zh-cn

表3 请求Body参数

参数

是否必选

参数类型

描述

databases

Array of CreateGaussMySqlDatabase objects

数据库信息列表,列表最大长度为50。

表4 CreateGaussMySqlDatabase

参数

是否必选

参数类型

描述

name

String

数据库名称,数据库名称长度可在1~64个字符之间,由字母、数字、下划线、中划线组成,中划线的累计总长度小于等于10个字符,且不能包含其他特殊字符。

character_set

String

数据库使用的字符集名称,如utf8mb4、gbk。

comment

String

数据库备注,长度不能超过512个字符,不能包含回车和特殊字符!<"='>&。

users

Array of GaussMySqlDatabaseUser objects

数据库用户列表,即创建数据库时同步授权给列表中的用户,列表最大长度为50。列表可以为空,即创建数据库时不授予其权限到数据库用户,在需要给该数据库授权某数据库用户时,调用数据库用户授权接口即可。

表5 GaussMySqlDatabaseUser

参数

是否必选

参数类型

描述

name

String

数据库用户名。

host

String

主机地址。

readonly

Boolean

是否为只读权限:

  • true:表示只读。

  • false:表示可读写。

响应参数

状态码: 201

表6 响应Body参数

参数

参数类型

描述

job_id

String

创建数据库的任务ID。

状态码: 400

表7 响应Body参数

参数

参数类型

描述

error_code

String

错误码。

error_msg

String

错误消息。

状态码: 500

表8 响应Body参数

参数

参数类型

描述

error_code

String

错误码。

error_msg

String

错误消息。

请求示例

创建数据库,字符集为utf8mb4,读写权限。

POST https://{endpoint}/v3/054e292c9880d4992f02c0196d3ea468/instances/a23fb62bd61e4e9e9636fd2225f395bein07/databases

{
  "databases" : [ {
    "name" : "test",
    "character_set" : "utf8mb4",
    "comment" : "database_comment",
    "users" : [ {
      "name" : "gaussdb_mysql_user1",
      "host" : "127.0.0.1",
      "readonly" : false
    } ]
  } ]
}

响应示例
