已解决...在报表实验室的表内使用 url 图像的解决方案：

from PIL import Image as pillowImage
from django.core.files.storage import default_storage
from io import BytesIO
from reportlab.platypus import Image
cloud_image = default_storage.open('url') # using s3Storage 
img = pillowImage.open(cloud_image)
img_byte_arr = BytesIO()
img.save(img_byte_arr, format=img.format)
result = Image(img_byte_arr, w * cm, h * cm)
....
data1 = [[result]]
t1 = Table(data1, colWidths=(9 * cm))
t1.setStyle(TableStyle([('VALIGN', (0, 0), (-1, -1), 'LEFT'),]))
t1.hAlign = 'LEFT'
story.append(t1)
...
