获取文件创建日期在HTTP [英] Get File Creation Date Over HTTP

问题描述

鉴于Web服务器的文件（例如， http://foo.com/bar.zip - >只能通过访问HTTP），有没有什么办法没有在第一时间下载整个存档来获得日期属性（例如，日期[创建，修改]）？

Given a file on a webserver (e.g., http://foo.com/bar.zip -> only accessible through HTTP), is there any way to get the date attributes (e.g., date [created, modified]) without downloading the entire archive in the first place?

现在，我下载的存档和编程读取属性。麻烦的是，档案是几十MIB，所以它似乎是一种资源的浪费，下载整个事情并最终读完只是几个字节的信息。

Right now, I download the archive and read the attributes programmatically. Trouble is that the archive is dozens of MiB so it seems like a waste of resources to download the entire thing and end up reading off just a couple of bytes of information.

我认识到，带宽几乎是免费的，但我不喜欢在任何情况下浪费了。

I realize that bandwidth is practically free, but I don't like to be wasteful in any case.

推荐答案

试着读从头部的Last-Modified
