event.headers
event.headers["X-Requested-With"]
var headerItem = "x-requested-with"
event.headers.headerItem
等等,似乎什么都没有定义
据Cloudwatch称,此次活动是:

“x-requested-with”标题在那里,但它似乎从未定义过,当我试图以编程方式访问它时,它应该在
事件标题中
从,它说

}
更新(基于您新提供的信息):
您要查找的标题是x-request-with
而不是x-request-with
(注意大小写)
请注意,Javascript中的对象查找区分大小写
如果要使用变量检索它,可以执行以下操作
var headerItem = "x-requested-with"
event.headers[headerItem]
如果它不在event.headers
中,则会出现其他问题。您能否console.log(event)
并将其包含在您的问题中?
var headerItem = "x-requested-with"
event.headers[headerItem]
