Received username, string length greater than or equal to 2 bits, incorrect use
Username string ` validate:"required,min=2," `
The console prompts that the validation label on the error information field “username” is invalid
After finding the validate document, the correct import method is used. After using the string format restrictions such as min, the require is no longer used
Username string ` validate:"min=0,max=5" ` //use requier instead of min
