Because the demand for work, the need butt SMS gateway, when the business is a registered user, the phone needs to send a verification code; other companies are likely to use third-party interfaces, but the big point of the company, for safety, they have their own SMS message Center (SMSC)
1. business needs
- 1. docking SMS Gateway, send a message, a downlink transmission (MT) using openSMPP open source development kit
- 2. verification code using redis storage (mainly, distributed storage, support expiration time)
2. The following is a simple example of the code (including transmission message authentication code storage and redis)
pom add a dependent

3. Verify PIN
Here the code is not posted, directly from the phone number to redis query, if value is compared whether right or wrong, without value, direct throw to the verification code is invalid
4. docking gateway api

The SMS gateway simulator
Docking test how the test environment is a problem, find a simulation SMPP from the Internet, I feel very good use, share address here: SMPP simulator
