100分求解文件下载的问题！

Question

我想下载一片文件，从网站入口一步一步点下载可以真实下载下来；但是直接下载文件的真实路径出错，提示文件不存在。
网站上的“保存”是一个按钮，鼠标放在按钮上状态栏提示 
javascript:saveasxml("123456","123456");
如何编写下载程序 能够下载这个网站上的文件？？？
高分求解！！！！！！！

Answer 1

楼上的不诚心，我说过直接这么下载提示下载不下来；
UrlDownloadFile（）我提供真实的URL都不能下载 只有通过网站 点击SAVE按钮 才能下载！

Answer 2

用察看源代码，然后分析看看javascript:saveasxml是如何实现的。

Answer 3

javascript:saveasxml("123456","123456");
是哪个网站的？把它的脚本下载下来看看不就行了。这种下载方法实际上是别为了实现防盗URL地址.

Answer 4

httpheader 中判断referer（从哪一个url访问过来的）通常用于防盗链，你可以使用commview先抓取鼠标点击下载的http头，再用wininet api把这些header初始化之后提交，请求文件，就可以得到了一句话，先抓包，构造包，提交

Answer 5

如果是单纯的javascrip脚本可以分析得出来,但如果里面有ASP动态生成的代码那就难了.

Answer 6

call IHTMLAnchorElement::click
handle BeforeNavigate2 and get the URL of the file
download the file. 

Answer 7

比如下载到的文件为1019980023646.tar 点击保存按钮
通过Commview抓取到含有 1019980023646.tar 字符的包只有一个如下:

唉 web方面就没怎么接触 头脑总晕忽忽的 呵呵

Answer 10

要从这个js函数：saveasxml下手

Answer 11

m_sUrl = "patent_eng/XML/1019980023646/1019980023646.TAR";
pConnection = session.GetHttpConnection("patent2.kipris.or.kr");
pFile = pConnection->OpenRequest(CHttpConnection::HTTP_VERB_GET,
m_sUrl,
"http://patent2.kipris.or.kr/patent_eng/KP/KPXV1010.jsp?APPLNO=1019980023646&PUBREG=P",
1,
NULL,
"HTTP/1.1",
INTERNET_FLAG_RELOAD|INTERNET_FLAG_DONT_CACHE);result = pFile->SendRequest(); 
pFile->QueryInfoStatusCode(dwRet);最后得到的dwRet值总是404，Sever not Found.
该如何修改函数？还请各位多帮忙，拜谢了！
