Quick integration

Throughout the integration, whenever the merchant system intends to interact with the Alipay system for a specific service, it needs to send HTTP/HTTPs requests to the corresponding interfaces. After receiving the request, the Alipay system will first verify the request; if the verification is successful, then the Alipay system will respond the result data to the merchant server.
