文章摘要
A PHP-based solution is introduced for preventing domain detection by WeChat when sharing external websites, particularly for marketing purposes. It utilizes a fallback domain to circumvent restrictions, displaying a prompt page on iOS WeChat and directly redirecting to the target website through Android's inbuilt browser. The system uses user agent detection to differentiate between iOS and Android WeChat clients and applies appropriate redirection techniques. The interface provides step-by-step guidance and interactive buttons to assist users in accessing the resource center. The method relies on client-side scripting and response headers to manage browser compatibility and user experience.
