在S3存储桶中的Lambda Python boto3存储文件(Lambda Python boto3 store file in S3 bucket)

在S3存储桶中的Lambda Python boto3存储文件(Lambda Python boto3 store file in S3 bucket)

好的，我已经看到了一些这样的例子，这是我在AWS Lambda Python 3.6中的代码：

# I just wrote out the file before this... import boto3 tmp = open('/tmp/' + name_str,"rb") s3_client = boto3.resource('s3') bucket = s3_client.Bucket(S3BUCKETNAME) bucket.put_object(Key=name_str, Body=tmp, ContentType='text/csv', ContentEncoding='utf-8')

我得到的错误是：

's3.ServiceResource'对象没有属性'put_object'：AttributeError

那么，我试试：

s3_client.upload_file('/tmp/' + name_str, S3BUCKETNAME, name_str)

's3.ServiceResource'对象没有属性'upload_file'：AttributeError

所以...我必须遗漏一些基本的东西......还有其他一些进口吗？ 为什么系统找不到这些功能？

ok, I've seen a few examples of this, and here is my code in AWS Lambda Python 3.6:

# I just wrote out the file before this... import boto3 tmp = open('/tmp/' + name_str,"rb") s3_client = boto3.resource('s3') bucket = s3_client.Bucket(S3BUCKETNAME) bucket.put_object(Key=name_str, Body=tmp, ContentType='text/csv', ContentEncoding='utf-8')

The error I get is :

's3.ServiceResource' object has no attribute 'put_object': AttributeError

Well, then I try:

s3_client.upload_file('/tmp/' + name_str, S3BUCKETNAME, name_str)

's3.ServiceResource' object has no attribute 'upload_file': AttributeError

So... I must be missing something basic... Is there some other import? Why can't the system find these functions?

最满意答案

这是对使用何种类型的误解。 应该是：

s3_client = boto3.client（'s3'）

但请注意，我现在实际使用的代码更像是：

s3_client = boto3.client('s3') with open('/tmp/' + name_str) as file: object = file.read() s3_client.put_object(Body=object, Bucket=S3BUCKET, Key=name_str, ContentType='whatever/something', ContentEncoding='whatever-itis', StorageClass='PICK_ONE', ACL='you_choose')

This was a misunderstanding of what type to use. It should have been:

s3_client = boto3.client('s3')

But note that the code I actually use now is more like:

s3_client = boto3.client('s3') with open('/tmp/' + name_str) as file: object = file.read() s3_client.put_object(Body=object, Bucket=S3BUCKET, Key=name_str, ContentType='whatever/something', ContentEncoding='whatever-itis', StorageClass='PICK_ONE', ACL='you_choose')
