2.1. Introduction to SMS service

At present, there are many short message services provided by third parties in the market. These third-party short message services will connect with various operators (China Mobile, China Unicom and Telecom). We only need to register as a member and call according to the provided development documents to send short messages. It should be noted that these SMS services are paid services.
For this project, we choose the SMS service provided by Alibaba cloud.
Short Message Service is a communication service provided by Alibaba cloud for users. It supports sending SMS verification codes and SMS notifications quickly. The three networks in one exclusive channel is interconnected with the number carrying network transfer platform of the Ministry of industry and information technology in real time. Carrier level operation and maintenance support, real-time monitoring and automatic switching, and the arrival rate is as high as 99%. The SMS service API provides the capabilities of SMS sending, sending status query and batch sending. After adding signatures and templates on the SMS service console and passing the approval, you can call the SMS service API to complete SMS sending and other operations.

Don't tell anyone! among Number, you are authenticating the national guest system of the United States year. Don't tell others! Where {number} is a dynamic parameter, which needs to be controlled in the code later.

2.5. Setting access keys

Identity authentication is required when sending SMS. SMS can be sent only after authentication. This section is to set the key and key used for identity authentication when sending SMS. Place the mouse over the current user's Avatar in the upper right corner of the page, and a drop-down menu will appear:
