wget 没有检索到正确大小的文件（文件损坏或不完整？）

  • 772

我不明白...

实际的下载链接似乎不是 http 链接，而是一些 Javascript 操作？

javascript:SendFileDownloadCall('PRODIMAGES.CIF.zip','PRODIMAGES.CIF.zip');

所以手动下载后，我去浏览器的下载历史复制直接链接 https://au.ingrammicro.com/_layouts/CommerceServer/IM/FileDownload.aspx?DisplayName=STD_FULL_FILEFEED.TXT&FileName=STDPRICE_FULL.TXT.zip

我将 URL 连同我的网站凭据一起输入 wget：

wget -q --user=XXXX --password=XXXX "https://au.ingrammicro.com/_layouts/CommerceServer/IM/FileDownload.aspx?DisplayName=STD_FULL_FILEFEED.TXT&FileName=STDPRICE_FULL.TXT.zip" -o STDPRICE.zip

后来，我发现添加 --user 和 --password 没有区别，所以我省略了：

[root@server datafiles]# wget "https://au.ingrammicro.com/_layouts/CommerceServer/IM/FileDownload.aspx?DisplayName=STD_FULL_FILEFEED.TXT&FileName=STDPRICE_FULL" -O STDPRICE.zip

无论如何，我没有获得与通过人工点击并从网站下载获得的文件相同的文件，而是获得了一个小得难以置信的文件。

确认我的恐惧，当我尝试解压缩时，我得到：

$ [root@server datafiles]# unzip STDPRICE.zip
Archive:  STDPRICE.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of STDPRICE.zip or
        STDPRICE.zip.zip, and cannot find STDPRICE.zip.ZIP, period.

档案检查：

$ [root@server datafiles]# file STDPRICE.zip
STDPRICE.zip: HTML document, UTF-8 Unicode text, with very long lines, with CRLF line terminators

那么 wget 实际上已经下载了一个 HTML 文件，该文件被呈现为一个.txt.zip文件？有人可以启发我吗？

wget

    该站点将您重定向到登录页面：

    HTTP request sent, awaiting response... 302 Moved Temporarily

    它可能不接受您作为基本身份验证提供的凭据（这是 wget 发送的），而是使用会话 cookie。您可以尝试从浏览器中提取 cookie（在登录时）并使用 wget ( --load-cookies) 发送它们。他们可能还会关注您可能尝试修改的请求的其他方面（例如用户代理）。

    如果您可以改用 curl，请打开检查器 ( Ctrl+Shift+I)，转到网络选项卡，下载文件，右键单击请求列表中的下载条目，将鼠标悬停在“复制”上，然后选择“复制为 cURL”，现在剪贴板上的命令将包含 cookie。
