How to send verification code to mobile phone?
I. Preface
Technical name: Ali is greater than SMS verification (one of the ways to send SMS verification is more authoritative).
SMS publishing process:

We usually don't have to write our own code (because we usually have no qualification, if we write our own code, the amount of code will be very large). We need to find a third-party service to write code for us.
Call the third-party service (such as weather service, etc.) and pass the corresponding parameters (such as mobile phone number, etc.). In this case, Ali is more than the service to send SMS verification code.
Alicloud: a cloud collection of servers (hundreds of thousands, millions of machines).
Server: computer with server software installed.
Three networks in one, server cluster, load balancing strategy (load balancer nginx), server downtime, remote disaster recovery strategy.

2, Sending steps of SMS verification code:
(1) Login Ali is greater than:
(2) Register an alicloud account.
(3) Log in to alicloud account:

(4) Application signature:

(5) Application template:

(6) Example of sending SMS:

(7) Phone received verification code:

(8) To view help documents:

(9) Get key

(10) Java code implementation:
1) Guide jar package
2) Code:

		 //Required: mobile number to be sent. Batch call is supported in the form of comma separation. The maximum batch number is 1000 mobile phone numbers. Batch call is slightly delayed compared to the timeliness of a single call. SMS with verification code type is recommended to use a single call method. When sending international / Hong Kong, Macao and Taiwan messages, the receiving number format is international area code + number, such as "85200000000"

		 //Required: SMS template - can be found in SMS console. When sending international / Hong Kong, Macao and Taiwan messages, please use the international / Hong Kong, Macao and Taiwan SMS template

		 //Friendly tip: if a line break is required in JSON, please refer to the standard JSON protocol for line break requirements. For example, if the SMS content contains a line break, it needs to be expressed as \ \ r\n in JSON. Otherwise, it will cause JSON to fail to parse on the server
		 //"{\"name\":\"Tom\", \"code\":\"888888\"}"
