然后,在MainObject中,我们使用@ValidateNested()和@Type()装饰器来指定嵌套对象的验证规则。 在你的控制器或服务中,使用class-validator库中的validate()函数来验证传入的数据。例如: 代码语言:txt 复制 import { Controller, Post, Body } from '@nestjs/common'; import { validate } from 'class-validator'...

Please note that nested object must be an instance of a class, otherwise @ValidateNested won't know what class is target of validation.Check also Validating plain objects. 意思是嵌套的对象必须是一个明确的class类,如果不定义的话,ValidateNested是无法知道检验对象的。此时需要根据提示查看Validating plain...
class User { @IsString()userName: string;@IsObject()address: Address;} 当使⽤上述结构时，由于IsObject只能检验User的address属性是否是对象，⽆法对其内部使⽤已经定义好的检验⽅式进⾏检验（上述Address中的IsString与IsNumber⽆效）解决⽅法 先说结论，使⽤ValidateNested与Type注解结合使⽤，可...
