如何使用API网关调用AWS步骤功能?

问题描述：

根据Amazon的文档，可以使用HTTP API调用step函数.

According to Amazon's documentation, step function can be invoked using HTTP API.

步骤功能可以与步骤功能一起访问和使用控制台，AWS开发工具包或HTTP API.

Step Functions can be accessed and used with the Step Functions console, the AWS SDKs, or an HTTP API.

我试图搜索详细信息，但似乎找不到任何好的信息.有谁知道如何使用API网关调用AWS步骤功能，类似于调用Lambda函数的方式吗?

I tried to search the detailed information, but can't seem to find any good ones. Does anyone know how to invoke AWS step function using API gateway, similar to the way it invokes Lambda functions?

答

如果您需要从API网关调用StepFunction，现在可以在文档中进行详细说明:

If you need to call StepFunction from API Gateway, it's now possible and described well in docs: https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-api-gateway.html

对于集成类型，选择AWS Service
对于AWS服务，从列表中选择Step Functions
对于HTTP方法，从列表中选择POST
对于操作类型，选择Use action name
要执行操作，请键入StartExecution
对于执行角色，请输入具有API Gateway受信任身份提供者和附加策略AWSStepFunctionsFullAccess

For Integration Type, choose AWS Service
For AWS Service, choose Step Functions from the list
For HTTP Method, choose POST from the list
For Action Type, choose Use action name
For Action, type StartExecution
For Execution Role, type ARN of role with API Gateway trusted identity provider and attached policy AWSStepFunctionsFullAccess
