我正在尝试将一个Lambda函数调用到一个“示例应用程序”堆栈中,但由于我正在尝试传递一个名为“this”的参数,因此它给出了一个错误。
这是我的Lambda函数
export async function handler(event) {
console.log("request:", JSON.stringify(event, undefined, 2));
return {
statusCode: 200,
headers: { "Content-Type": "text/plain" },
body: `Hello, CDK! You've hit ${event.path}\n`
};
};
这里是调用那个函数的“应用”
//import sns = require('@aws-cdk/aws-sns');
//import subs = require('@aws-cdk/aws-sns-subscriptions');
//import sqs = require('@aws-cdk/aws-sqs');
import cdk = require('@aws-cdk/core');
import lambda = require('@aws-cdk/aws-lambda');
//Exports class from other file much like a function
export class CdkWorkshopStack extends cdk.Stack {
constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
super(scope, id, props);
// Describes an AWSLambda Resource
const hello = new lambda.Function (this, 'HelloHandler', {
runtime: lambda.Runtime.NODEJS_8_10, //execution environment
code: lambda.Code.asset('lambda'), // code loaded from the "lambda" directory
handler: 'hello.handler' // file is "hello", function is "handler"
});
}
}
我遇到的错误是:
lib/cdk-workshop-stack.ts:31:39 - error TS2345: Argument of type 'this' is not assignable to parameter of type 'Construct'.
Type 'CdkWorkshopStack' is not assignable to type 'Construct'.
