Terraform：需要一個屬性值，由等號（“=”）引入

我正在開發一個使用 HTTPS/POST 請求將 API Gateway 集成到 DynamoDB 的 terraform 腳本。基本目標是將 API 請求正文中傳遞的記錄插入 DynamoDB 表中。我正在使用 aws_api_gateway_integration 來定義集成，并且我正在傳遞應包含兩個屬性（BusinessUnitId和Frequency）的請求模板。我的腳本如下所示 -

resource aws_api_gateway_integration schedule_post_integration {
  rest_api_id             = aws_api_gateway_rest_api.schedule.id
  resource_id             = aws_api_gateway_resource.schedule_resource.id
  http_method             = aws_api_gateway_method.schedule_post_method.http_method
  type                    = "AWS"
  integration_http_method = "POST"
  uri                     = "arn:aws:apigateway:${var.target_region}:dynamodb:action/PutItem"
  credentials             = aws_iam_role.schedule_api_dynamodb_role.arn
  request_templates       = {
    "application/json" = EOF
    {
        "TableName" : "${var.environment_id}-AccountService-NotesToDatalakeSchedule",
        "Item" : {
            "BusinessUnitId" : {
                "N" : "$input.path('$.BusinessUnitId')"
            },
            "Frequency" : {
                "N" : "$input.path('$.Frequency')"
            }
        }
    }
  }
}

我找不到正確的語法來指示應如何在 request_templates 中傳遞Item 。在部署期間它會拋出錯誤 -

有人可以幫我確定這里的問題嗎？

uj5u.com熱心網友回復：

看起來您正在嘗試使用 HCL Template Expressions，但您忘記了兩個關鍵事項：

1. 模板運算式以<< MARKER, 您選擇EOF作為標記但忘記了<<
2. 您忘記了“單獨一行”的標記。

固定版本：

resource aws_api_gateway_integration schedule_post_integration {
  rest_api_id             = aws_api_gateway_rest_api.schedule.id
  resource_id             = aws_api_gateway_resource.schedule_resource.id
  http_method             = aws_api_gateway_method.schedule_post_method.http_method
  type                    = "AWS"
  integration_http_method = "POST"
  uri                     = "arn:aws:apigateway:${var.target_region}:dynamodb:action/PutItem"
  credentials             = aws_iam_role.schedule_api_dynamodb_role.arn
  request_templates       = {
    "application/json" = << EOF
    {
        "TableName" : "${var.environment_id}-AccountService-NotesToDatalakeSchedule",

            },

            }
