我正在使用blobstore上傳和下載python版Google App Engine中的文件。我知道如何逐行編寫對象到blobstore,並且我知道如何POST和下載blobstore項目,但是如果我擁有的是blobstore項目,那麼如何逐行讀取blobstore中的數據?在Google App Engine中,您如何使用blobstore鍵逐行讀取blob?
file_name = files.blobstore.create(mime_type='application/octet-stream')
with files.open(file_name, 'a') as f:
f.write("data")
files.finalize(file_name)
# Get the file's blob key
blob_key = files.blobstore.get_blob_key(file_name)
#starting with the blob_key, read from the blobstore line-by-line.
# ???
#with files.open() as f:
#foo = f.read()
