Question

我正在制作一个脚本，将来自互联网的PDF（不保存到磁盘）转换为一系列jpeg，然后将JPG保存到AWS s3。

不幸的是，下面的代码只将PDF的第一页保存为AWS。有关如何修改它以使用顺序文件名将图像保存到AWS的任何想法？

from urllib2 import urlopen
from wand.image import Image
from io import BytesIO
import boto3
    s3 = boto3.client(
        's3',
        aws_access_key_id='mykey',
        aws_secret_access_key='mykey'
    )

    bucket_name = 'testbucketAWS323'
    #location on disk

    #file prefix
test_id = 'example'
f = urlopen("https://s3.us-east-2.amazonaws.com/converted1jpgs/example.pdf")
bytes_io_file = BytesIO()
with Image(file=f) as img:
    print('pages = ', len(img.sequence))
    with img.convert('png') as converted:
        bytes_io_file = BytesIO(converted.make_blob('jpeg'))
      #code below should take 'converted' object, and save it to AWS as jpg. 
        s3.upload_fileobj(bytes_io_file, bucket_name, "assssd.jpg")
        print 'done'

只需枚举文档页面（if ($this->object->billing_state === 'SC') { $this->send( 'sc@gmail.com', $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() ); } if ($this->object->billing_state === 'RS') { $this->send( 'rs@gmail.com', $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() ); } if ($this->object->billing_state === 'PR') { $this->send( 'pr@gmail.com', $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() ); } else { $this->send( 'else@gmail.com', $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() ); }）即可获取页码＆amp;资源。将页面资源复制到wand.image.Image.sequence的新实例后，直接导出blob，并且不必担心中间转换。

如何在转换时使用upload_fileobj方法？

Python + Wand.Image - 使用连续的pagenumber.jpg名称
