• 在计算机中创建文件夹。
• 将您的文本文件的图像URL的文件夹中。
• cd到该文件夹。
• 使用wget -i images.txt
• 您将在文件夹中找到所有下载的文件。

在Windows 10/11上，这是相当琐碎的使用

for /F "eol=;" %f in (filelist.txt) do curl -O %f

请注意，包含eol=;允许我们通过在filelist.txt中我们不想要的那些行的开头添加;来屏蔽个别排除。
因此，在我的系统中，我只需键入并输入Do GetFileList，所有存储的URL都将下载，其中Do是一个旧的DO技巧，可以在一个自编辑zip文件中保存许多小命令，但现在我使用CMD，其中Do Edit将其调用为Notepad "%~f0"来粘贴这样的部分。
Do.bat的一部分

:GetFileList
Rem as posted to https://stackoverflow.com/questions/42878196
for /F "eol=;" %%f in (filelist.txt) do curl -O %%f
exit /b 0
goto error GetFileList

Windows 7有一个FTP命令，但它经常会弹出一个需要用户授权响应的防火墙对话框。
目前运行Windows 7并希望下载URL列表而不下载任何wget.exe或其他依赖项，如curl.exe（这将是最简单的第一个命令），最短的兼容方法是power-shell命令（不是我最喜欢的速度，但如果需要必须。
带有URL的文件是filelist.txt，IWR是wget的PS近似等价物。
Security Protocol first命令确保我们使用的是现代TLS1.2协议
-OutF ... split-path ...意味着文件名将与远程文件名相同，但在CWD（当前工作目录）中，如果需要，可以使用cd /d folder进行脚本编写。

PS> [Net.ServicePointManager]::SecurityProtocol = "Tls12" ; GC filelist.txt | % {IWR $_ -OutF $(Split-Path $_ -Leaf)}

要作为CMD运行，请在'Tls12'周围使用稍微不同的引号

PowerShell -C "& {[Net.ServicePointManager]::SecurityProtocol = 'Tls12' ; GC filelist.txt | % {IWR $_ -OutF $(Split-Path $_ -Leaf)}}"

这需要制作成一个具有错误处理功能的函数，但它会重复下载图像进行图像分类项目

search()

在这个python project中，我在www.example.com中进行搜索unsplash.com，它会给我一个URL列表，然后我将其中的一些URL（由用户预先定义）保存到一个预先定义的文件夹中。

在Windows上，install wget - https://sourceforge.net/projects/gnuwin32/files/wget/1.11.4-1/
并将C:\Program Files (x86)\GnuWin32\bin添加到您的环境路径。
创建一个文件夹，其中包含所有要下载的图像的txt文件。
在文件资源管理器顶部的位置栏中键入cmd
当命令提示符打开时，输入以下内容。
wget -i images.txt --no-check-certificate
