[使用Python 3使用Google Cloud Function重命名对象

Posted 2023-02-02

我正在从我的云函数运行以下代码：

from google.cloud import storage


def rename_blob(bucket_name, blob_name, new_name):
    """Renames a blob."""
    bucket_name = "gk-12345"
    blob_name = "gk.txt"
    new_name = "gk-2343.txt"

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

    print(blob)
    print(new_name)

    new_blob = bucket.rename_blob(blob, new_name)

    print("Blob  has been renamed to ".format(blob.name, new_blob.name))

我遇到以下错误：

错误：功能终止。推荐的操作：检查日志以了解终止原因。详细信息：rename_blob（）缺少2个必需项位置参数：“ blob_name”和“ new_name”

代码段来自https://cloud.google.com/storage/docs/renaming-copying-moving-objects#code-samples_2

有人可以帮忙。

谢谢！

编辑

我更改了代码：

 from google.cloud import storage
import datetime


def rename_blob(bucket_name, blob_name=None, destination_bucket_name=None,destination_blob_name=None):
    """Copies a blob from one bucket to another with a new name."""
    #time = datetime.datetime.now().strftime("%H%M%S")
    #bucket_name = "gk-12345"
    #blob_name = "gk.txt"
    #destination_bucket_name = "gk-12345"
    #destination_blob_name = blob_name+time


    storage_client = storage.Client()

    source_bucket = storage_client.bucket(bucket_name)
    source_blob = source_bucket.blob(blob_name)
    destination_bucket = storage_client.bucket(destination_bucket_name)

    blob_copy = source_bucket.copy_blob(
        source_blob, destination_bucket, destination_blob_name
    )

    print(
        "Blob  in bucket  copied to blob  in bucket .".format(
            source_blob.name,
            source_bucket.name,
            blob_copy.name,
            destination_bucket.name,
        )
    )

time = datetime.datetime.now().strftime("%H%M%S")
bucket_name = "gk-12345"
bName = "gk.txt"
dbName = "gk-12345"
dbNameTime = bName+time
rename_blob(bucket_name, blob_name=bName, destination_bucket_name=dbName,destination_blob_name=dbNameTime)

我现在遇到以下错误：

答案

问题出在函数的参数中。也许您在不传递所有3个参数的情况下调用函数。

另一答案

注意您的错误：
