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,可进行嵌套结构的检验。 以下是寻找解决方案的心路历程: 查看class-validator的npm网站,其中插件特性介绍中...
查了一圈发现了一个叫class-validator的东西,是nestjs框架里的默认工具。这玩意儿能用在前端吗? 能!使用起来大概长这个样子 import {validate, ValidateNested,IsNotEmpty,Equals, Length, IsArray} from "class-validator"; let hasOwnProperty = Object.prototype.hasOwnProperty; let propIsEnumerable = Object.p...
在上面的代码中,我们定义了一个嵌套对象NestedObject,并使用@IsNotEmpty()装饰器来验证每个属性的非空性。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...
import { IsString } from 'class-validator'; export class MyDTO { @IsString() MY_ENV_VARIABLE: string; } 在需要验证的地方,比如Controller中的某个方法,使用validate()函数来验证环境变量。首先,将ValidationPipe添加到当前模块的providers中: 代码语言:txt 复制 import { ValidationPipe } from '@nes...
Validating nested objects If your object contains nested objects and you want the validator to perform their validation too, then you need to use the @ValidateNested() decorator: import {ValidateNested} from "class-validator"; export class Post { @ValidateNested() user: User; } Inheriting Val...
