我想你想使用get_blob_to_bytes、或get_blob_to_text；这些应该输出一个字符串，你可以用它来创建一个数据帧

I think you want to use get_blob_to_bytes, or get_blob_to_text; these should output a string which you can use to create a dataframe as

from io import StringIO
blobstring = blob_service.get_blob_to_text(CONTAINERNAME,BLOBNAME)
df = pd.read_csv(StringIO(blobstring))
