(The content control of web pages promoted by WeChat/QQ is becoming more and more strict. If your domain name is blocked by WeChat and users cannot open it, it will cause a lot of traffic loss and customer loss. When we do promotion, we need to check the domain name to determine whether it is blocked by WeChat. Then at this time, the domain name detection interface must be used to detect the status of the domain name in real time, query whether the domain name is intercepted by QQ/WeChat, and notify in time if there is an exception, which is very stable and accurate. Therefore, adjustments can be made in a short time without affecting the operation of the website and personnel.)
