Whether app or web will use SMS verification function, Ali provides high-quality SMS services.
This will integrate step records for future reference.

Access key and Access key Secret

1. Register the developer of Ali Open Platform and authenticate it by real name.
2. Open Ali Short Message Service
3. Click on the Access Key button in the SMS console to view Access key and Access key Secret

4. To create short message signatures, individual users can only create one short message signature, while enterprise users can create five short message signatures.
5, SMS signature is the main name of SMS, for example, Alipay's short message is Alipay, and Alipay is short message signature. Short message signature needs to be audited after submission. It can be audited and approved within 2 hours of normal working time.

6. Create a short message template: The short message template is the content of the short message. If there are parameters in the short message, it can be set by referring to Ali's parameter template.

These things are ready for development.

2. Integrated Short Message Function

1. Download two jar packages of Ali SMS and import them into the project
2. Coding with reference to official demo
I wrote a tool class myself. It's very simple.
If there is more demand, it can be expanded on the basis of it.

3. Call, test
SendSmsResponse response = SmsUtil.sendIdentifyingCode(mobile,sixCode);
After successful debugging, the background returns to app Json with a prompt: {"code": 0, "data": {}, "message": "successful sending"}
The mobile phone receives short messages:

Registration or login using authentication code

At the back end, a random six-digit number is generated and sent to the mobile phone, and the verification code database is inserted at the same time.
Determine the corresponding relationship between mobile phone number and authentication number in the table when logging in or registering.
After successful login or registration, the consumed authentication code is deleted from the database.

Fourth, recharge and check the arrival rate of short messages

After the integration is successful, the error code will be found to indicate that the account balance is insufficient after the test.
At this time to Ali's SMS console, to recharge, in the absence of purchasing packages, a text message is 0.045 yuan, or 4:5.
It's rather expensive. Save 10 yuan.

Five, summary

Ali's short message arrival rate is still very high. More than a dozen were sent, none of them failed.

There is a long way to go. Vegetables are not the original sin, but degeneration is the original sin.
