safari pac file debug

pac.js

// 在macOS Safari中调试代理pac文件的方法
// 思路：把调试信息转换为域名，并使用Wireshark抓包
// Wireshark规则： (dns) && (dns.qry.name contains "test-pac.local") 

function sanitizeAndConvertToDomain(input) {
    // 去除非法字符，只保留字母、数字、点和连字符
    const sanitized = input.replace(/[^a-zA-Z0-9.-]/g, '');
    // 确保字符串以域名格式返回
    const parts = sanitized.split('.');
    const domain = parts.filter(part => part.length > 0).join('.');

    return domain;
}

function proxyify(input) {
    return "PROXY " + sanitizeAndConvertToDomain(input)+".test-pac.local;";
