How to validate incoming requests in a Golang API
Article Introduction：Using structure tags combined with go-playground/validator library is the best practice for verification requests in GoAPI. It can ensure data integrity, security and behavioral predictability; by adding validate tags (such as required, email, min, max, etc.) to structure fields, and parsing JSON in the processor for verification, clear and maintainable verification logic can be achieved; for simple scenarios, manual verification can be used to check field validation through type assertions and conditions; middleware can also use unified processing of public verification (such as header information, query parameters), and through regular or dedicated libraries (such as gorilla/sc
