[C # source code] Baidu online storage address batch conversion tool

The process starts with a simple process, that is, simulating a browser to access the address of the Baidu disk and then extracting the actual address. The core function is this:

 

[Csharp]
// Baidu disk address http://pan.baidu.com/share/link? Consumer id = 112694 & uk = 455690558
Private string ConvertBaiduPan_Thunder (string strBaiduPan)
{
If (strBaiduPan = null)
{
Return null;
}
 
String strThunder = null;
// Access Baidu disk address
String strBaiduPanWebPage = MyHttp. GetHtml (strBaiduPan );
If (strBaiduPanWebPage = "")
{
MessageBox. Show ("access address failed! "+ StrBaiduPan );
Goto End;
}

The above function is used to retrieve the file address from the Baidu Network Disk. It's easy to match web page capture and text, right. If you have any questions, read the source code or leave a message for me. As a Tom, he is happy to communicate with many cainiao.
