今天晚上舍友让我帮他下载百度网盘的文件，4个文件加起来一共有1G左右。很自然就想到了axel，axel是linux下一个多线程下载工具。服务器网速相当的给力，可以达到近20M/s，于是就用浏览器中的百度下载链接进行下载，操作如下：
axel -n 20 "http://p.baidupcs.com/file/06dfde33e680e0229aee3ff35d198f11?xcode=7437cf1a12d0b63b1d183308c7cafebfd8fa3b6aeef88597&fid=3960367452-250528-1762279860&time=1393070029&sign=FDTAXER-DCb740ccc5511e5e8fedcff06b081203-xB5Ig4NANcRT9PpPx0MszWsH7No%3D&to=pb&fm=N,B,G,e&expires=1393073366&rt=sh&r=619186119&logid=914083266&sh=1&vuk=3960367452&fn=BL5%E5%9B%BD%E8%A1%8C2.12.0.zip" Initializing download: http://p.baidupcs.com/file/06dfde33e680e0229aee3ff35d198f11?xcode=7437cf1a12d0b63b1d183308c7cafebfd8fa3b6aeef88597&fid=3960367452-250528-1762279860&time=1393070029&sign=FDTAXER-DCb740ccc5511e5e8fedcff06b081203-xB5Ig4NANcRT9PpPx0MszWsH7No%3D&to=pb&fm=N,B,G,e&expires=1393073366&rt=sh&r=619186119&logid=914083266&sh=1&vuk=3960367452&fn=BL5%E5%9B%BD%E8%A1%8C2.12.0.zip HTTP/1.0 403 Forbidden
最后一句显示了下载被禁止。
下面对链接进行转化，一共2步：
第1步：将http://p.baidupcs.com替换为http://115.231.84.42/cdn.baidupcs.com
第2步：在url最后加上&wshc_tag=0&wsiphost=ipdbm
这样就完成了地址转化，再次测试如下：

下面提供一个shell脚本，直接提供转化：
#!/bin/bash
#baidu download address convert
if [ $# == 0 ]
then
echo "paramter is missing"
else
address=$1
echo ""
echo "==========================new baddi download address=============================="
new_address=${address/p.baidupcs/115.231.84.42\/cdn.baidupcs}"&wshc_tag=0&wsiphost=ipdbm"
echo $new_address
echo "=================================================================================="
