我正在尝试验证我的PUT用户/端点的参数,但是我希望所有参数都是可选的,但是一旦api使用者填写了这些参数,我就想对其进行验证。
我尝试将@ApiModelProperty必需的false与验证管道装饰器组合在一起,但是验证管道接管了ApiModelProperty (发送400个错误请求HttpException非常正常)
这是我的DTO: usersUpdate.dto.ts
import { IsEmail, IsEnum, IsPhoneNumber, IsEmpty } from 'class-validator';
import { ApiModelProperty } from '@nestjs/swagger';
import { RoleType } from './role-type.enum';
class UserInfo {
@ApiModelProperty({ description: 'User firstname', required: false })
readonly firstname: string;
@ApiModelProperty({ description: 'User lastname', required: false })
readonly lastname: string;
@ApiModelProperty({description: 'User postal address', required: false })
readonly address: string;
@ApiModelProperty({ description: 'User phone number', required: false })
@IsPhoneNumber('FR')
readonly phone: string;
@ApiModelProperty({ description: 'User siret number', required: false })
readonly siret: string;
}
export class UpdateUserDTO {
@ApiModelProperty({ description: 'User email address', required: false })
readonly email: string;
@ApiModelProperty({ description: 'User password', required: false })
readonly password: string;
@ApiModelProperty({ description: 'User informations', required: false })
readonly user_info: UserInfo;
@ApiModelProperty({ enum: ['Admin', 'Runner', 'Dispatcher'], description:'User role', required: false })
readonly role: RoleType;
@ApiModelProperty({ description: 'User activation token', required: false })
readonly activationToken: string;
}
我想在电子邮件参数上使用和@IsEmail()
装饰器,并且在角色中使用@Enum()
装饰器,但是一旦使用这些装饰器,该参数就是必填项。
有人知道如何在参数为空的情况下跳过此验证器吗?
答案 0 :(得分:1)
是的,您可以通过应用 class-validator 中的@IsOptional
装饰器使字段中的验证器为可选。
您可以代替@ApiModelProperty({ description: 'User activation token', required: false })
使用的另一种方法是@ApiModelPropertyOptional
,从而删除声明的 必需的:false 部分。
最后,您甚至可以使用@IsEmail()
装饰器来验证email字段是否为电子邮件,最后可以做的是将@IsNotEmpty()
和@IsOptional()
组合在一起,以便当字段为前提是它不能为空。
提供的代码如下:
import { IsEmail, IsEnum, IsPhoneNumber, IsEmpty, IsOptional } from 'class-validator';
import { ApiModelPropertyOptional } from '@nestjs/swagger';
import { RoleType } from './role-type.enum';
class UserInfo {
@ApiModelPropertyOptional({ description: 'User firstname' })
@IsOptional()
readonly firstname: string;
@ApiModelPropertyOptional({ description: 'User lastname' })
@IsOptional()
readonly lastname: string;
@ApiModelPropertyOptional({description: 'User postal address' })
@IsOptional()
readonly address: string;
@ApiModelPropertyOptional({ description: 'User phone number' })
@IsOptional()
@IsPhoneNumber('FR')
readonly phone: string;
@ApiModelPropertyOptional({ description: 'User siret number' })
@IsOptional()
readonly siret: string;
}
export class UpdateUserDTO {
@ApiModelPropertyOptional({ description: 'User email address' })
@IsEmail()
@IsOptional()
readonly email: string;
@ApiModelPropertyOptional({ description: 'User password' })
@IsOptional()
readonly password: string;
@ApiModelPropertyOptional({ description: 'User informations' })
@IsOptional()
readonly user_info: UserInfo;
@ApiModelPropertyOptional({ enum: ['Admin', 'Runner', 'Dispatcher'], description:'User role' })
@IsEnum(RoleType)
@IsOptional()
readonly role: RoleType;
@ApiModelPropertyOptional({ description: 'User activation token' })
@IsOptional()
readonly activationToken: string;
}
让我知道是否有帮助;)
