如何在不创建临时本地文件的情况下将文件上传到S3 [英] How to upload a file to S3 without creating a temporary local file

问题描述

有没有可行的方法将动态生成的文件直接上传到Amazon s3，而无需先创建本地文件然后上传到s3服务器？我使用python。谢谢

Is there any feasible way to upload a file which is generated dynamically to amazon s3 directly without first create a local file and then upload to the s3 server? I use python. Thanks

推荐答案

下面是一个示例（使用请求库）下载图像并将其上传到s3，而不写入本地文件的示例：

Here is an example downloading an image (using requests library) and uploading it to s3, without writing to a local file:

import boto
from boto.s3.key import Key
import requests

#setup the bucket
c = boto.connect_s3(your_s3_key, your_s3_key_secret)
b = c.get_bucket(bucket, validate=False)

#download the file
url = "http://en.wikipedia.org/static/images/project-logos/enwiki.png"
r = requests.get(url)
if r.status_code == 200:
    #upload the file
    k = Key(b)
    k.key = "image1.png"
    k.content_type = r.headers['content-type']
    k.set_contents_from_string(r.content)
