破解淘宝网图片链接地址
破解淘宝网图片链接
在淘宝网淘东西的时候，看到一个好宝贝，有时想把宝贝的图片下载回家跟家人分享。可我发现淘宝商家的图片真实链接地址根本就看不到。我通过查看网页的代码，发现淘宝做了一个flash作为图片的查看器，它屏蔽掉了IE的图片保存功能。点击图片下面那个“放大图片”功能，会弹出一个链接地址经过加密的的页面，我用javascript写了一个简单的解密程序，实现了解密这个链接地址的功能，从而取得真实的图片路径。
程序如下：
<html>
<head>
<script language="javascript">
function becode(opString)
{
var _local2 = opString;
var _local3 = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
var bits;
var decOut = new Array ();
var _local1 = 0;
var j = 0;
_local1 = 0;
while (_local1 < _local2.length) {
bits = ((((_local3.indexOf(_local2.charAt(_local1)) & 255) << 18) | ((_local3.indexOf(_local2.charAt(_local1 + 1)) & 255) << 12)) | ((_local3.indexOf(_local2.charAt(_local1 + 2)) & 255) << 6)) | (_local3.indexOf(_local2.charAt(_local1 + 3)) & 255);
decOut[j++] = (bits & 16711680) >> 16;
decOut[j++] = (bits & 65280) >> 8;
decOut[j++] = bits & 255;
_local1 = _local1 + 4;
}
if (_local2.charCodeAt(_local1 - 2) == 61) {
decOut.pop();
decOut.pop();
} else if (_local2.charCodeAt(_local1 - 1) == 61) {
decOut.pop();
//
}
return (decOut);
}
function cecode(var1)
{
var _local3 = becode(var1);
var _local2 = "";
var _local1 = 0;
while (_local1 < _local3.length) {
_local2 = _local2.concat(String.fromCharCode(_local3[_local1]));
_local1++;
}
return (_local2);
}
function decode(var1, key)
{
var _local3 = var1;
_local3 = becode(_local3);
var2 = "";
var _local2 = 0;
var _local1 = 0;
while (_local1 < _local3.length) {
var2 = var2.concat(String.fromCharCode(_local3[_local1] ^ key.charCodeAt(_local2++)));
if (_local2 >= key.length) {
_local2 = 0;
}
_local1++;
}
return (var2);
}
function Button1_onclick()
{
var index = 0;
var url = form1.Text1.value;
if ((index = url.indexOf("pic=")) >=0)
{
index += 4;
url = url.substr(index,url.length-index);
index = 0;
if ((index = url.indexOf("&")) >=0)
{
url = url.substr(0,index);
}
}
index = 0;
form1.Text2.value = decode(url,"3irjklsd8432uisdklvr892348");
if ((index = form1.Text2.value.lastIndexOf(".jpg")) >= 0)
{
index += 4;
form1.Text2.value = form1.Text2.value.substr(0,index);
form1.photo.src=form1.Text2.value;
}
}
</script>
<script id="clientEventHandlersJS" language="javascript">
