我使用 mongoDb 和 nodeJs 创建了一个简单的 crud API lambda，它运行良好。所以我转到另一个步骤，我目前正在使用 yaml 文件中的开放 api 规范创建一个带有 terraform 的 AWS API 网关。这是我的招摇文件：

在我的 terraform 中，我删除了集成和方法，因为我在我的招摇中添加了它们。所以我需要在 aws_api_gateway_rest_api 中导入 swagger 文件body = data.template_file.swagger.rendered
resource "aws_api_gateway_rest_api" "api" {
name = "api-gateway"
description = "document api"
body = data.template_file.swagger.rendered
}
data "template_file" "swagger" {
template = jsonencode("${path.module}/../../../../shared/swagger.yaml")
vars = {
get_lambda_arn = local.get_lambda_arn
}
}
output "json" {
value = data.template_file.swagger.rendered
}
locals {
get_lambda_arn = aws_lambda_function.lambda_document.invoke_arn
}
resource "aws_api_gateway_resource" "documents" {
rest_api_id = aws_api_gateway_rest_api.api.id
parent_id = aws_api_gateway_rest_api.api.root_resource_id
path_part = "documents"
depends_on = [aws_api_gateway_rest_api.api]
}
resource "aws_api_gateway_resource" "document_by_id" {
parent_id = aws_api_gateway_resource.documents.id
path_part = "{documentId}"
rest_api_id = aws_api_gateway_rest_api.api.id
}
resource "aws_api_gateway_deployment" "ApiDeloyment" {
rest_api_id = aws_api_gateway_rest_api.api.id
stage_name = "INT"
depends_on = [aws_api_gateway_rest_api.api]
}
resource "aws_lambda_function" "lambda_document" {
function_name = "lambda_document"
handler = "lambda.handler"
role = "arn:aws::iam::123456:role/irrelevant"
runtime = "nodejs10.x"
filename = "${path.module}/lambda.zip"
source_code_hash = filebase64sha256("${path.module}/lambda.zip")
}
应用 terraform 后，我在 terraform 日志中收到此消息
terraform apply --auto-approve

我的 docker-compose 日志显示了这一点

PS：我尝试使用 JSON 但同样的问题
有什么解决办法吗？我想在 localstack 中使用 terraform 将 swagger 与 api 网关集成
