Why is event.requestContext undefined for my AWS Lambda function?-CodePudding

Why was I unable to obtain the remote IP address of the user?

When I clicked on the test button or the function URL, it seems that event.requestContext was undefined. Why?

const res = { 
    statusCode: 200,
    isBase64Encoded: false,
    headers: { 
        "Access-Control-Allow-Origin":"*",
        "Content-Type": "text/plain" 
    },
    multiValueHeader: {}
};

export const handler = async(event) => {
    const ip = event.requestContext.identity.sourceIp;
    res.body="hi " ip; 
    return res;
}

CodePudding user response：

It seems that the event format is incorrect. This works:

const ip = event.requestContext.http.sourceIp;

What I used was the format for Lambda version 1 but I am now using version 2.
