这是一个 pconline APP下载页面获取真实下载地址的测试
分析页面
第一部分：
tempurl="http://dlc2.pconline.com.cn/filedown_55919_6912056/zhifubaoqianbao.apk"
第二部分
<script type="text/javascript">
function genLink(token) {
if(token) {
$('a.sbDownload').each(function(){
var linkUrl = $(this).attr("tempUrl");
if(linkUrl.indexOf("http://dlc2.pconline.com.cn/filedown") != -1) {
var idx = linkUrl.lastIndexOf("/");
var file = linkUrl.substring(idx);
var newLink = linkUrl.substring(0,idx)+'/'+token+file;
$(this).attr("href", newLink).attr('target','_blank');
}
});
}
}
(function(){
setTimeout(function(){
$.getScript('http://dlc2.pconline.com.cn/dltoken/55919_genLink.js');
},1000);
})();
</script>
先访问：
http://dlc2.pconline.com.cn/dltoken/55919_genLink.js
获取token
获取token后，再将token与tempurl组装为真实的下载地址
结构如下：
http://dlc2.pconline.com.cn/filedown_55919_6912056/xxxxxxxx/zhifubaoqianbao.apk"
