使用python将文件上传到google-cloud-storage存储桶时捕获异常

from google.cloud import storage

def upload_file(bucket_name, source_file_path, destination_blob_name):
    try:
        # 初始化存储桶客户端
        client = storage.Client()

        # 获取存储桶引用
        bucket = client.get_bucket(bucket_name)

        # 上传文件
        blob = bucket.blob(destination_blob_name)
        blob.upload_from_filename(source_file_path)

        print("文件上传成功！")
    except storage.exceptions.GoogleAuthError as e:
        print("Google Cloud认证凭据错误:", e)
    except storage.exceptions.NotFound as e:
        print("存储桶或文件不存在:", e)
    except storage.exceptions.Forbidden as e:
        print("权限不足:", e)
    except Exception as e:
        print("上传文件时发生未知异常:", e)

# 调用示例
bucket_name = "your-bucket-name"
source_file_path = "path/to/source/file.txt"
destination_blob_name = "file.txt"

upload_file(bucket_name, source_file_path, destination_blob_name)
