Python：上傳Pillow Image到Firebase存儲桶

Question

我想弄清楚如何將Pillow Image實例上傳到 Firebase 存儲桶。 這可能嗎？

這是一些代碼：

from PIL import Image

image = Image.open(file)
# how to upload to a firebase storage bucket?

我知道有一個gcloud-python庫，但這是否支持Image實例？ 將圖像轉換為字符串是我唯一的選擇嗎？

Answer 1

gcloud-python庫是正確使用的庫。 它支持從字符串，文件指針和文件系統上的本地文件上傳（請參閱docs ）。

from PIL import Image
from google.cloud import storage

client = storage.Client()
bucket = client.get_bucket('bucket-id-here')
blob = bucket.blob('image.png')
# use pillow to open and transform the file
image = Image.open(file)
# perform transforms
image.save(outfile)
of = open(outfile, 'rb')
blob.upload_from_file(of)
# or... (no need to use pillow if you're not transforming)
blob.upload_from_filename(filename=outfile)

Answer 2

這是直接將枕頭圖片上傳到firebase存儲的方法

from PIL import Image
from firebase_admin import credentials, initialize_app, storage

# Init firebase with your credentials
cred = credentials.Certificate("YOUR DOWNLOADED CREDENTIALS FILE (JSON)")
initialize_app(cred, {'storageBucket': 'YOUR FIREBASE STORAGE PATH (without gs://)'})

bucket = storage.bucket()
blob = bucket.blob('image.jpg')

bs = io.BytesIO()
im = Image.open("test_image.jpg")
im.save(bs, "jpeg")

blob.upload_from_string(bs.getvalue(), content_type="image/jpeg")
