amazon-web-services - 使用 aws Lambda 时无法加载 kinesis 本机库

问题描述

我正在尝试上传 lambda 函数，其中我使用 kinesis 视频流我可以在本地使用它，因为"libKinesisVideoProducerJNI.so"当我将它上传到 AWS lambda 时我可以链接本机库我不断收到错误

如何将本机库添加/链接到 aws Lambda？

用java编写的代码，我使用eclipse构建/上传到AWS lambda

标签： amazon-web-servicesaws-lambdaamazon-kinesis

解决方案

通过将文件上传到 S3 Bucket 来解决问题，然后将文件作为 S3Object 取回并将其保存到"/tmp/libKinesisVideoProducerJNI.so"然后加载它

S3Object libso = awsObject.getObject(s3Client, "bucket", "libKinesisVideoProducerJNI.so");

            File lib = awsObject.save(libso.getObjectContent(), "/tmp/libKinesisVideoProducerJNI.so");

            System.out.println("library file was saved to " + lib.getAbsolutePath());

            System.load(lib.getAbsolutePath());
