我有一個非常具體的問題。所以我正在編寫一個應用程序，它接收一個整數和一個文件在燒瓶中，並將它們作爲關鍵值對存儲在MongoDB中。我在一個爲mongo工作的朋友的幫助下編寫了mongo部分，並且這部分代碼工作正常。我想知道現在我應該如何將我從Flask收到的文件發送到mongoDB中。使用Flask，pymongo和GridFS將文件存儲到MongoDB中？
TLDR。我正在將文件寫入磁盤，如何使用我已知的函數將它們存儲在mongoDB中，但是我自己沒有寫入？
教程採取在文件中，我發現在http://runnable.com/UiPcaBXaxGNYAAAL/how-to-upload-a-file-to-the-server-in-flask-for-python
我談論我的GitHub的託管代碼https://github.com/DavidAwad/SpaceShare/blob/master/init.py
如果你看看行56我想放入的MongoDB就在那裏，然後從磁盤上刪除它，但是我知道這是非常低效的，所以如果有辦法讓它只能直接在mongoDB中寫入和寫入，那麼我都是耳朵。
我特別感興趣的代碼是這樣的。
# put files in mongodb
def put_file(file_location, room_number):
db_conn = get_db()
gfs = gridfs.GridFS(db_conn)
with open(file_location, "r") as f:
gfs.put(f, room=room_number)
# read files from mongodb
def read_file(output_location, room_number):
db_conn = get_db()
gfs = gridfs.GridFS(db_conn)
_id = db_conn.fs.files.find_one(dict(room=room_number))['_id']
#return gfs.get(_id).read()
with open(output_location, 'w') as f:
f.write(gfs.get(_id).read())
... code code code
#make the file same, remove unssopurted chars
filename=secure_filename(file.filename)
#move the file to our uploads folder
file.save(os.path.join(app.config['UPLOAD_FOLDER'],filename))
put_file(app.config['UPLOAD_FOLDER'],space) #PUT IN MONGODB HERE? IS THIS HOW I DO THAT???
# remove the file from disk as we don't need it anymore after database insert.
os.unlink(os.path.join(app.config['UPLOAD_FOLDER'] , filename))
# maybe redirect user to the uploaded_file route, which will show the uploaded file.
