Examples of using the free SMS verification code interface on the Tianyi open platform

The Tianyi open platform provides a free SMS verification code API. let's take a look at how to use it. We use the python development interface for many Verification codeFor the solution, this API is backed by China Telecom, a heavyweight operator. it should be reliable and free of charge.

Usage:
# Define app_id and app_secret
R = RandCode ('app _ id', 'app _ secret ')
# Two supported platform interfaces
# Method 1: Customize the callback URL for receiving the verification code
R. send ('phone number', 'http: // yourdomain/rand_code.php ', '3 ')
# Method 2: custom verification code content
R. send_sms ('phone number', 189189)
