通过Referer进行请求防盗链。

示例代码

function verifyReferer(referer) {
    let regex = /ctyun/;
    return regex.test(referer);
}

async function verifyHeaderParameters(request) {
    //401表示鉴权不通过
    let statuscode = 401
    let result = 'Referer verification failed!'
    try {
        if(verifyReferer(request.headers.get("referer")) == true){
            statuscode = 200
            result = "Referer verification succeeded!"
        }
    } catch (error) {
        result = error
    }
    return new Response(result, { "status": statuscode });
}

addEventListener('fetch', event => {
    event.respondWith(verifyHeaderParameters(event.request))
})
