从Lambda访问S3存储桶

0

【以下的问题经过翻译处理】 我试图从Lambda函数中写入S3存储桶,并且已经配置好所需的权限和角色,但是我遇到了以下错误:

“errorMessage”:“An error occurred (AccessDenied) when calling the PutObject operation: Access Denied"

以下是我的策略文件,并且我已经在Lambda函数执行角色中分配了相关角色。您能否指出我在这里遗漏了什么。谢谢。

【以下的回答经过翻译处理】 首先,这里有很多你的Lambda函数并不需要的权限。我建议你删除这里设置的90%的权限。

除此之外,假设你的策略实际上在资源中没有读取<my-bucket-name>,那么有两件事需要注意:对于桶级别操作,用arn:aws:s3:::<bucket-name>是可以的,但对于对象,你需要指定路径。例如,对于桶中的所有对象,你需要使用arn:aws:s3:::<bucket-name>/*

同时请注意,如果你使用了CMK(你自己手动创建的一种KMS密钥,不是aws/s3 的这种)对存储桶中的文件进行了加密,那么你还需要为服务(lambda、脚本等)提供访问该KMS密钥的权限,以便操作文件的加密(加密或解密或两者都有)。
