將圖像上傳到 Google Cloud 而不是保存到磁盤 (Python)

Question

我有一個腳本，它從網絡下載某些圖像（<1 MB）並保存到本地磁盤。 我可以將它保存到 Google Cloud Storage 存儲分區而不是本地系統嗎？

def downloadImage(url):
    try:
        print("Downloading {}".format(url))
        image_name = str(url).split('/')[-1]
        resp = urlopen(url)
        image = np.asarray(bytearray(resp.read()), dtype="uint8")
        image = cv2.imdecode(image, cv2.IMREAD_COLOR)
        cv2.imwrite(current_path + "\\Downloaded\\" + image_name, image)
    except Exception as error:
        print(error)

您可以使用GCS Python 客戶端庫以編程方式執行與 GCS 相關的任務。 以下代碼會將位於/PATH/TO/SOURCE_FILE的本地文件上傳到 GCS 存儲桶gs://BUCKET_NAME

from google.cloud import storage

def upload_blob(bucket_name, source_file_name, destination_blob_name):
    """Uploads a file to the bucket"""

    storage_client = storage.Client()
    bucket = storage_client.bucket(bucket_name)
    blob = bucket.blob(destination_blob_name)

    blob.upload_from_filename(source_file_name)

    print(
        "File {} uploaded to {}.".format(
            source_file_name, destination_blob_name
        )
    )


BUCKET_NAME = "BUCKET_NAME"
SOURCE_FILE_NAME = "/PATH/TO/SOURCE_FILE"
DESTINATION_FILE_NAME = "DESTINATION_FILE"

upload_blob(BUCKET_NAME, SOURCE_FILE_NAME, DESTINATION_FILE_NAME)

請記住，為了使用upload_blob方法，必須安裝 GCS Python 客戶端庫並設置身份驗證憑據。 您可以在此處找到有關如何實施這些步驟的信息。

試試這個： https : //cloud.google.com/python

請記住，始終檢查是否有您想要的庫。
