问题描述
我正在使用boto3制作备份脚本，并使用以下行来上传项目:
I'm making a backup script using boto3 using this line to upload the item:
bucket.upload_file(backup_file_name,bucket_path+backup_file_name)
如何验证此文件是否确实已上传到我的存储桶?我尝试使用boto3 doc查找内容，但未找到任何内容.这种方法会引发我可以处理的任何异常吗?
How can I verify if this file has really been uploaded to my bucket? I tried to find something using boto3 doc but I didn't found anything. Does this method throws any exception that I can handle?
推荐答案
它将提高boto3.exceptions.S3UploadFailedError.您还可以执行 head_object 请求以验证对象看起来像它应该的样子.如果对象不存在，则会使用代码404引发botocore.ClientError.
It will raise boto3.exceptions.S3UploadFailedError. You can also do a head_object request to verify that the object looks like it should. This will raise a botocore.ClientError with the code 404 if the object does not exist.
