修改代理会话一致性

功能介绍

修改代理会话一致性。

调用方法

请参见如何调用API

URI

PUT /v3/{project_id}/instances/{instance_id}/proxy/{proxy_id}/session-consistence

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。

proxy_id

String

数据库代理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

缺省值:en-us

表3 请求Body参数

参数

是否必选

参数类型

描述

session_consistence

String

会话一致性。

取值范围:

  • true:时表示会话一致性开启。

  • false:时表示会话一致性关闭。

consistence_mode

String

一致性模式。默认值为空,此时以会话一致性参数session_consistence的值为准。

取值范围:

  • session:会话一致性。

  • global:全局一致性。

  • eventual:最终一致性。

响应参数

状态码: 200

表4 响应Body参数

参数

参数类型

描述

job_id

String

任务ID。

状态码: 400

表5 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6 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。
