问题描述

在aws-sdk的S3类中， upload() 和 putObject() ?他们似乎做同样的事情.为什么我会更喜欢一个?

In the aws-sdk's S3 class, what is the difference between upload() and putObject()? They seem to do the same thing. Why might I prefer one over the other?

推荐答案

使用AWS开发工具包 putObject() 参数如下:

The difference between using AWS SDK upload() and putObject() param is as below:

• 如果上传完成时报告的MD5不匹配，则它 重试.
• 如果文件足够大，它将使用分段上传进行上传 平行零件.
• 根据客户端的重试设置重试.
• 您可以用于进度报告.
• 如果不提供，则基于文件扩展名设置ContentType 它.

• If the reported MD5 upon upload completion does not match, it retries.
• If the file size is large enough, it uses multipart upload to upload parts in parallel.
• Retry based on the client's retry settings.
• You can use for Progress reporting.
• Sets the ContentType based on file extension if you do not provide it.
