Question

我是AWS新手。我知道这可能是个非常外行的问题。但我试图传递并接受AWS lambda代理中的参数。我能够使用body mapping模板在AWS lambda中执行此操作，是否有任何方法可以在Lambda代理中使用AWS lambda中的queryString映射

Answer 1

如果您使用的是Lambda Proxy，API Gateway会将整个客户端请求映射到后端lambda函数的输入事件参数，如下所示。

{
   "resource": "Resource path",
   "path": "Path parameter",
   "httpMethod": "Incoming request's method name"
   "headers": {Incoming request headers}
   "queryStringParameters": {query string parameters }
   "pathParameters":  {path parameters}
   "stageVariables": {Applicable stage variables}
   "requestContext": {Request context, including authorizer-returned key-value pairs}
   "body": "A JSON string of the request payload."
   "isBase64Encoded": "A boolean flag to indicate if the applicable request payload is Base64-encode"}

请参阅AWS的设置代理集成documentation。

以下是解析事件数据（如查询字符串）的example。

如果有人使用无服务器框架来开发和部署lambdas和API网关，那么有一种不同的方法可以将API网关配置为使用开放API规范（即Swagger）的AWS lambda代理！请参阅以下配置示例。
