如何在 Node 12.x (Amazon2) 的 Lambda 中获取 curl
How to get curl in Lambda for Node 12.x (Amazon2)
Lambda 中新的 nodejs 运行时基于 Amazon2，未预安装 curl。因此在尝试使用它时给出 curl: command not found。
如何让 curl 回到新的 nodejs 10.x and 12.x 运行时？
我找不到 curl lambda 层。
推荐的方法是为 nodejs 使用 request 客户端。但是，如果您在从 node 8.x 升级到 node 12.x 时过度使用 curl，您将需要自己包含 curl 二进制文件和所需的库.
我创建了一个 lambda 层 arn:aws:lambda:us-east-1:310788757301:layer:curl:15。您可以自由使用它，但我将其用于个人用途，因此我不建议在生产环境中使用它。相反，我会为您提供构建您自己的 curl lambda 层的指南。
我上传了 curl 7.69.1 (x86_64-redhat-linux-gnu)，并使用 ldd /opt/bin/curl 找出缺少哪些库。包括所有必需的库后，输出如下：
