How does java realize the function of sending SMS verification code?

1. Create an Http mock request tool class, and then write a POST method or a GET method.

Out.println (sendmsg ("18123456789, 15 123456789"), "Dear user, your verification code is" +sendmsgutil ". Creatrandomvcode ()+",valid for 60 seconds. }

Then execute it. Under normal circumstances, if the parameters are passed correctly and operated according to the specification of the interface file, it will be sent successfully and the mobile phone can receive the verification code. Then the possible problem is that the content of the short message sent may be garbled in Chinese, and then it will not be successful. Just code according to the requirements of the SMS platform. It is usually UTF 8 encoding.
