将图像字节上载到cloudinary的正确方法

Question

我用http://cloudinary.com/documentation/image_upload_api_reference作为参考。在

有两种情况下，我想将文件上传到cloudinary。在

1. 上传图片直接给网址链接。在
2. 上传图片字节，从不同的来源。在

我可以解决第一个案子，但第二个案子有麻烦。我在下面粘贴我的代码流以供参考。在

import cloudinary
import cloudinary.uploader

from io import BytesIO
from StringIO import StringIO

def upload_image_to_cloudinary(img_tag):

  logging.debug("Uploading Image to cloudinary : %s"%img_tag)

  if 'src' not in img_tag.attrs:
    del img_tag
    return

  img_src = img_tag['src']

  if img_src.startswith('/blob'):

    quip_client = pgquip.get_client()
    blob_ids = img_src.split('/')
    blob_response = quip_client.get_blob(blob_ids[2], blob_ids[3])

    img_src_str = blob_response.read()  # this returns str object.
    # img_src = BytesIO(img_src_str)
    img_src = StringIO(img_src_str)

  cloudinary_response = cloudinary.uploader.upload_image(
    img_src,
    use_filename=True,
    folder="/pagalguy/articles",
    width=546,
    crop="limit"
  )

  img_tag['src'] = cloudinary_response.metadata.get("url")

  return img_tag

如果img_src是另一个api返回的图像blob str，我将其作为在cloudinary doc中提到的fileparam，其传递方式与任何外部图像url（例如：https://media.licdn.com/mpr/mpr/shrinknp_400_400/AAEAAQAAAAAAAAIkAAAAJGRhNzJiYjY1LTUxOTctNDI4NC1hOGIwLWQ1OTVlNmZlZmVmYw.jpg）非常相似

为了检查一般上传流如何像s3的boto一样工作，我检查了下面的repo代码。 也提到了https://github.com/boto/boto/blob/develop/boto/vendored/six.py#L633这个。在

错误日志：

最后，我不知道上传图片字节到cloudinary的正确方法是什么。在

Answer 1

表示img_src的img_src参数应使用字节数组缓冲区（bytearray）或Base64 URI填充。你可以尝试一下：

    with open(img_src_str, "rb") as imageFile:
      f = imageFile.read()
      img_src = bytearray(f)

    cloudinary_response = cloudinary.uploader.upload(
      img_src,
      ...
    )
