结合Lambda集成和CloudFront，API Gateway忽略了多个Set-Cookie头信息

我的设置看起来像这样。

|––––––––––––|                  |–––––––––––––|     |–––––––––––––––––|
|            |  <- origin 1 ->  | API Gateway | <-> | Lambda function |
|            |                  |–––––––––––––|     |–––––––––––––––––|
| CloudFront |  
|            |                  |–––––––––––––|
|            |  <- origin 2 ->  |  S3 bucket  |
|––––––––––––|                  |–––––––––––––|
我需要在API网关前的CloudFront来获得自动的http->https重定向。

我正在使用一个自定义的login.example.com子域和CloudFront。

API Gateway生成的URL是CloudFront分发的起源1。
这一切都像预期的那样运作。
我甚至可以从lambda函数中返回一个Set-Cookie头，它将被传递下去，直到到达浏览器。
"statusCode": 302,
"body": "",
"headers": {
"location": "/test",
"surrogate-control": "no-store",
"cache-control": "no-store, no-cache, must-revalidate, proxy-revalidate",
"pragma": "no-cache",
"expires": "0",
"content-length": "0",
"date": "Fri, 19 Feb 2021 17:25:56 GMT",
"connection": "keep-alive",
"set-cookie": "cookie1=68abcdbefbef7d84c26e68; Max-Age=2592000; Domain=example.com; Path=/; HttpOnly; Secure; SameSite=Strict"
"isBase64Encoded": false
再加一个就不行了--当你看了文档后就会发现。

"statusCode": 302,
"headers": {
"location": "/test",
"set-cookie": [
"cookie1=68abcdbefbef7d84c26e68; Max-Age=2592000; Domain=example.com; Path=/; HttpOnly; Secure; SameSite=Strict",
"cookie2-login=; Max-Age=0; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT; HttpOnly; Secure"
"surrogate-control": "no-store",
"cache-control": "no-store, no-cache, must-revalidate, proxy-revalidate",
"pragma": "no-cache",
"expires": "0",
"content-length": "0"
这两种情况都将被忽略/删除。
但是，即使我使用multiValueHeaders对象来返回一个以上的同类对象，像这样。
"statusCode": 302,
"body": "",
"headers": {
"location": "/test",
"surrogate-control": "no-store",
"cache-control": "no-store, no-cache, must-revalidate, proxy-revalidate",
"pragma": "no-cache",
"expires": "0",
"content-length": "0",
"date": "Fri, 19 Feb 2021 17:25:56 GMT",
"connection": "keep-alive"
"isBase64Encoded": false,
"multiValueHeaders": {
"Set-Cookie": [
"cookie1=68abcdbefbef7d84c26e68; Max-Age=2592000; Domain=example.com; Path=/; HttpOnly; Secure; SameSite=Strict",
"cookie2-login=; Max-Age=0; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT; HttpOnly; Secure"
API Gateway会从它传递给CloudFront的响应中删除/忽略它们。
我做错了什么？

在使用multiValueHeaders时，我是否必须在API网关中映射一些东西？

正常的headers['set-cookie']会自动传递，但multiValueHeaders却没有？

额外的属性是一个问题吗？

我试图为根域而不是login.example.com域设置cookie，这是不是一个问题？
