使用curl下载文件时如何保存远程文件名 [英] How do I preserve the remote filename when Downloading a file using curl

问题描述

可能重复：

如何使用响应头文件名和cURL保存文件

我需要下载成千上万种格式的图像

I need to download many thousands of images in the format

http://oregondigital.org/cgi-bin/showfile.exe?CISOROOT=/棒球&CISOPTR = 0

如果将该链接粘贴到浏览器中，它将尝试下载名为1.jp2的文件

If you paste that link in a browser, it tries to download a file named 1.jp2

我想用curl来做同样的事情。但是，当我运行

I want to use curl to do the same. However, when I run

curl -I' http://oregondigital.org/cgi-bin/showfile.exe?CISOROOT=/baseball&CISOPTR=0 '

文件名报告为404.txt，您可以下载该文件名，并查看它实际上是我想要的文件。我不能使用-O选项，因为分配给文件的名称不好，并且出于技术原因，我需要在系统上使用实际名称。

the filename is reported as 404.txt which you can download and see that it is actually the file I want. I can't use the -O option because the name assigned to the file is no good, and I have technical reasons for needing the actual name used on the system.

如何获得curl下载我在浏览器中可以顺利找到的相同文件的信息？谢谢。

How do I get curl to download the same file I have no trouble retrieving in my browser? Thanks.

推荐答案

解决方案是使用 -O -J

-O, --remote-name          Write output to a file named as the remote file  
-J, --remote-header-name   Use the header-provided filename

所以...

curl  -O -J  'http://oregondigital.org/cgi-bin/showfile.exe?CISOROOT=/baseball&CISOPTR=0'

我必须升级CURL。我有7.19版，但不支持-J，但有7.22版（最新）。

I had to upgrade my CURL. I had v 7.19 which doesn't support -J but 7.22 (which is the latest) does.
