python-3.x - Lambda Python boto3 将文件存储在 S3 存储桶中

Question

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' object has no attribute 'put_object': AttributeError

好吧，那我试试:

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

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

所以......我一定错过了一些基本的东西......还有其他的进口吗？为什么系统找不到这些功能？

这是对使用什么类型的误解。本来应该是:

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')
