在家的时候, 需要使用代理, 同时要使用图书馆的数据库, 两个代理有点冲突, 自己研究了一下
ssr 的规则, 发现比较简单.

可以页面后贴出的代码进行研究 pac.txt

pac 的内部完全就是 js 的语法逻辑, 不是十分熟悉, 写的有点硬, 可以自己考虑优化

执行从 FindProxyForURL 开始执行, 然后根据具体内容进行代理访问

按照学校代理的判断方式, 判断一个 url 是否符合图书馆给出的pac 地址,
将访问数据库的链接,执行 PROXY proxy2.lib.whu.edu.cn:81 代理链接, 第一次建立链接的时候, 需要使用图书馆帐号密码进行验证,

剩余的链接进行 ssr 验证, 进行正常的代理执行过程.

代码demo


// 默认使用的是 js 的语法

// 判断网站, 然后选择 代理位置
var direct = "DIRECT;";

var wall_proxy = function(){
   
    return "__PROXY__"; };
var wall_v6_proxy = function(){
   
    return "__PROXY__"; };

var ip_proxy = function(){
   
    return wall_proxy(); };
var ipv6_proxy = function(){
   
    return wall_v6_proxy(); };
var nowall_proxy = function(){
   
    return direct; };
