How to validate an array of strings using express validator?

Question

options = ['asdasda', 'asdasdas', 'asdasdasafsaafasfasfasfasfasfasasasasasdas', 'asd'];
req.check('options', 'Option must not exceed 30 characters').isLength({max: 30});

Am trying to validate each string in the array options. Is there any way to do it?

Answer 1

是的，您必须为此使用通配符。

req.check('options.*').isLength({ max: 30 })
