expressionvalidation器总是无效的
我build立一个最新版本的nodejs的项目，并express我有一个基本的网站设置即时通讯只是为了使用户身份validation工作（从中学习）
但无论我做什么，我都不能让express-validator来validation它，将永远是无效的
validator deprecated you tried to validate a undefined but this library (validator.js) validates strings only. Please update your code as this will be an error soon. node_modules/express-validator/lib/express_validator.js:338:41
这是我得到的唯一的错误，但即时通讯不知道该怎么做，因为一切似乎匹配github文档

而不是.notEmpty()检查与isEmpty()
来源： ValidateJS
isEmpty : validate.isEmpty(value) Check if the given value is non empty. The following value are considered empty: null undefined Empty strings Whitespace only strings Empty arrays Empty objects
