Question

我想create a step function API using API gateway使用Terraforms api_gateway_integration和sfn_state_machine。

我现在必须在api_gateway_integration处填写uri-parameter。

我的step函数已创建，我可以引用step函数的ID（类似arn:aws:states:*region*:*account*:stateMachine:*step-function-name*:stateMachine:*step-function-entry-point*）。

如果目标是AWS step函数，谁能告诉我该方案或uri参数外观的示例吗？

resource "aws_api_gateway_integration" "endpoint_integration" {
  ...
  integration_http_method = "POST"
  type = "AWS"
  uri = <<<<< What to place here???
}

与Terraform-integrate an AWS lambda with an API gateway相比，您不能从API网关“直接”（使用“ uri”-参数”指向特定的AWS状态机，而是aws_api_gateway_integration-resource指向AWS状态通常，AWS ARN会在请求中引用特定的AWS状态机。您可以使用API gateway request template从API网关映射到特定状态机，以便您可以省略请求API时，会死于stateMachineArn。有关详细说明，请参见AWS documentation "Creating a Step Functions API Using API Gateway"。

工作示例

# var.aws_region = eu-central-1
# var.sfn_orchestrater_arn = arn:aws:states:eu-central-1:*account*:stateMachine:*step-function-entry-point*
resource "aws_api_gateway_integration" "endpoint_integration" {
  http_method             = "POST"
  integration_http_method = "POST"
  type                    = "AWS"
  passthrough_behavior    = "NEVER"
  uri                     = "arn:aws:apigateway:${var.aws_region}:states:action/StartExecution"

  request_templates = {
    "application/json" = <<EOF
{
    "input": "$util.escapeJavaScript($input.json('$'))",
    "stateMachineArn": "${var.sfn_orchestrater_arn)}"
}
EOF
  }
}

Terraform：如果目标是aws_sfn_state_machine，则aws_api_gateway_integration的uri参数是什么
