我需要将文件上传到 S3，我想知道我应该使用哪个 boto3 api 调用？
我在 boto3 文档中找到了两种方法：
- http://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Client.upload_file
- http://boto3.readthedocs.io/en/latest/reference/customizations/s3.html
我是否使用 client.upload_file() ...
#!/usr/bin/python
import boto3
session = Session(aws_access_key_id, aws_secret_access_key, region)
s3 = session.resource('s3')
s3.Bucket('my_bucket').upload_file('/tmp/hello.txt', 'hello.txt')
还是我使用 S3Transfer.upload_file() ...
#!/usr/bin/python
import boto3
session = Session(aws_access_key_id, aws_secret_access_key, region)
S3Transfer(session).upload_file('/tmp/hello.txt', 'my_bucket', 'hello.txt')
任何建议，将不胜感激。提前致谢。

client = boto3.client("s3", "us-west-1", aws_access_key_id = "xxxxxxxx", aws_secret_access_key = "xxxxxxxxxx")
with open('drop_spot/my_file.txt') as file:
client.put_object(Bucket='s3uploadertestdeleteme', Key='my_file.txt', Body=file)
response = client.get_object(Bucket='s3uploadertestdeleteme', Key='my_file.txt')
print("Done, response body: {}".format(response['Body'].read()))
