wget 是 DL“downloading.aspx”；而不是“helloworld.doc”？
我为 wget 创建了两个文件： log.txt 和 docs.txt。
LOG.txt：

docs.txt 包含我要下载的文档的确切链接：例如
http://www.xyz.com/Docs/Download.aspx?id=133337
wget cmd： wget -c -o /home/repsak/project/log.txt -i /home/repsak/project/files.txt --load-cookies cookies.txt &
如果我将该链接复制到 Firefox，它会立即将该文档保存到我的硬盘上。
为什么我无法使用 wget 下载文件？
是因为这些文档包含了一些不同的 javascript 或其他东西吗？

I have created two files for wget:
log.txt and docs.txt.

docs.txt consist of the exact links to the documents I want to download: e.g.
http://www.xyz.com/Docs/Download.aspx?id=133337
wget cmd:
wget -c -o /home/repsak/project/log.txt -i /home/repsak/project/files.txt --load-cookies cookies.txt &
If I copy that link into firefox, It will instantly save the doc to my hdd.
Why can't I use wget to download the files?
Is it because the documents are wrapped around some different javascripts or something?
