What do you mean the verification code of electronic health card has reached the upper limit? When can I get it again?

Users can only get the verification code ten times a day by agreeing to the browser or the same 1IP address. Or the same mobile phone number, you can only get the SMS verification code three times, and the three restrictions are that one of them exceeds the limit, and the verification code will not be sent. The general method is to record the IP identification of the user's mobile phone number in the server and write it into a file, and then judge the number of times the user requests and sends the verification code by reading the file record.
