英文:
Why is event.requestContext undefined for my AWS Lambda function?
问题
为什么我无法获取用户的远程IP地址？
当我点击测试按钮或功能URL时，似乎event.requestContext未定义。为什么？
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;
}
英文:
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;
}

似乎事件格式不正确。这个部分是正确的：
const ip = event.requestContext.http.sourceIp;
我之前使用的是Lambda版本1的格式，但现在我正在使用版本2。
英文:
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.
