QQ手机版链接直接在Safari中打开

QQ手机版打开部分链接时会强制要求用户手动复制链接，非常繁琐。

使用这个Surge Script可以在右上角在Safari中打开时，解析原始url，然后用302跳过去

模式：Http Request

匹配URL：


https://c.pc.qq.com/.*\.html\?pfurl=.*

脚本内容：


// qq-direct.js

let headers = {};
headers['X-Modified-By'] = 'Surge';

// let oriurl = new URL($request.url).searchParame.get("pfurl")

let rawurl = undefined
try {
    rawurl = $request.url
} catch (e) {
    
}
if (!rawurl || rawurl === "http://www.example.com/") {
    console.log("[qq-direct] debugging")
    rawurl = 'https://c.pc.qq.com/middlem.html?pfurl=https%3A%2F%2Fstore.askey.com%2Fadt-3.html&gjsublevel=2804&pfuin=1474702730&pfto=mqq.group&type=0&gjlevel=15'
}
console.log("[qq-direct] rawurl: " + rawurl)
