Question

我有一个脚本，可以从Web下载某些图像（<1 MB）并保存到本地磁盘中。我可以将其保存到Google Cloud Storage存储桶而不是本地系统中吗？

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)

Answer 1

您可以使用GCS Python Client Library以编程方式执行与GCS相关的任务。以下代码会将位于/PATH/TO/SOURCE_FILE的本地文件上传到GCS存储桶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)

请记住，为了使用upload_blob方法，必须安装GCS Python客户端库并设置身份验证凭据。您可以找到here有关如何执行这些步骤的信息。

尝试一下：https://cloud.google.com/python

记住，请始终检查是否有您想要的库。

将图像上传到Google Cloud，而不是保存到磁盘（Python）
