Answer 1

您的 API 网关设置为代理 Lambda 集成还是 Lambda 集成？每个都有一个不同的事件结构，它会改变键所在的位置。

记录事件（print(event) 可以很好地用于测试运行）然后点击您的端点并查看事件结构是什么样的。这会告诉你键应该在哪里，或者你是否有错误的键值（事件结构不会经常更新，但它确实会发生，教程视频很快就会过时）

Lambda 的事件（事实上，所有 AWS 中的所有事件）只是 JSON 个对象。使用 python，它直接转换为字典，因此弄清楚正确的键结构可能有点奇怪，因为关于 AWS Sphere 中各种事件的文档分散在整个文档中，很难找到。

我通常在我的控制台上保留一个 lambda，它所做的只是 print(event) 然后将它连接到我当时尝试使用的任何触发器，这样我就可以看到它看起来漂亮而清晰。
