从URL批量下载图像，用于

Question

我需要site.com/folder/使用以下格式下载300张图像：1.png，2.png...300.png

有没有办法在批处理文件中或使用命令提示符来执行此操作？

Answer 1

WTH curl是这样的：

curl -o "#1.png" http://example.com/folder/[1-300].png

Answer 2

编号文件下载器 1.0

\n

这是一个完整的批处理脚本，它完全按照您的要求进行操作。您不需要下载任何可执行文件，这是 100% 批处理脚本，它应该适用于任何（最近的）Windows 安装。

\n

您需要做的就是编辑 _ URL变量（第 11 行）并将“example.com/folder...”替换为您要下载的文件的实际 URL。之后，您可以运行脚本并获取文件。

\n

\n
• 请注意，在您的 URL 中，此字符串：_NUMBERS _ 是一个关键字过滤器，将在最终下载函数中替换为递增的数字。
\n

\n

您下载的所有文件将保存在该脚本所在的目录中。您可以通过取消注释 _ SAVE_PATH变量（第 15 行）来选择其他目录。

\n

最后可以更改以下变量来配置数字序列：

\n

_ START：文件编号从此值开始。
\n_ STEP \xc2\xa0 ：在每个文件之间步进。
\n_ END \xc2\xa0\xc2\xa0 ：文件编号以此值结尾。

前导零

\n

目前，计数器不支持前导零。\nEX。从 Picture_001.jpg 到 Picture_999.jpg\n但除此之外它应该可以正常工作，如下所示：\nEX。从Picture_1.jpg到Picture_999.jpg
\n我会尝试找时间添加这个选项，应该不会太难。

如果需要，请随意修改和增强此脚本！
