Whether it is WeChat payment or Alipay payment, in fact, we all want to wake up the payment app from the browser through a unique schema. The agreement of Alipay is Alipay://,and the agreement of WeChat is WeChat://. In fact, the browser will crawl the http protocol, and both Alipay and WeChat will crawl their own protocols. It is precisely because of this that it is possible to wake up Alipay or WeChat in our app. Of course, the latter is likely to be restricted and will not be for a long time to come. It is these protocols that make h5 interact with app and make today's mobile operating system more prosperous.
