停止函数异步调用请求

功能介绍

当前仅支持参数recursive为false且force为true的函数。 在1:N的函数做并发异步调用的场景下调用停止异步请求接口时,同一函数实例同时在执行的其他请求也会被一并停止并返回4208 function invocation canceled

调用方法

请参见如何调用API

URI

POST /v2/{project_id}/fgs/functions/{function_urn}/cancel

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

租户项目 ID,获取方式请参见获取项目ID

function_urn

String

函数的URN,详细解释见FunctionGraph函数模型的描述。

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(响应消息头中X-Subject-Token的值)。

Content-Type

String

表3 请求Body参数

参数

是否必选

参数类型

描述

request_id

String

被停止的请求id

type

String

停止的类型 支持recursive, force。 recursive: 停止正在调用的子函数。 force: 直接终止runtime。

枚举值:

  • force

  • recursive
