Question

AWS just announced对Amazon API Gateway的HTTP API支持。这个新版本有一些非常令人印象深刻的价格和性能数字。最重要的是，AWS表示，使用v2的一般成本将比v1便宜70％，延迟降低50％。我很想在我现有的项目中尝试一下。

我在应用程序中使用无服务器框架。如何转换现有的API以使用此新功能？这是我的serverless.yml文件的样子：

service: amitsn-blog-api

# Use the serverless-webpack plugin to transpile ES6
plugins:
  - serverless-webpack
  - serverless-offline

# serverless-webpack configuration
# Enable auto-packing of external modules
custom:
  webpack:
    webpackConfig: ./webpack.config.js
    includeModules: true

provider:
  name: aws
  runtime: nodejs10.x
  stage: prod
  region: ap-south-1

  # 'iamRoleStatements' defines the permission policy for the Lambda function.
  # In this case Lambda functions are granted with permissions to access DynamoDB.
  iamRoleStatements:
    - Effect: Allow
      Action:
        - dynamodb:DescribeTable
        - dynamodb:Query
        - dynamodb:Scan
        - dynamodb:GetItem
        - dynamodb:PutItem
      Resource: "arn:aws:dynamodb:ap-south-1:*:*"
    - Effect: Deny
      Action:
        - logs:CreateLogGroup
        - logs:CreateLogStream
        - logs:PutLogEvents
      Resource: "*"

functions:
  # Defines an HTTP API endpoint that calls the main function in create.js
  # - path: url path is /posts

          cors: true
          integration: lambda
          request:
            template:
              application/json: '{ "postType" : "$input.params(''postType'')" }'
  update:
    # Defines an HTTP API endpoint that calls the main function in update.js
    # - path: url path is /posts/{id}

无服务器框架尚不支持HTTP API，尽管我们目前正在研究它！您可以在此处跟踪工作情况：https://github.com/serverless/serverless/issues/7052
