在使用class-validator进行参数校验的时候,会遇到[object,object]或[key:object]的情况!刚接触class-validator的小伙伴,遇到这种问题会比较头大(我刚遇到的这种情况也是很头大😂😂!)!废话不多少说,我们直接上代码: 1、数组中嵌套对象型-[object,object,...] 例如:[{self_warehouse_product_size_id: '1',st...
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...
是指在开发过程中,使用class-validator库对类中的某个字段进行验证。class-validator是一个基于装饰器的验证库,可以用于验证类中的属性是否符合指定的规则。 具体步骤如下: ...
validator: { validate(value: any, args: ValidationArguments) { const [relatedPropertyName] = args.constraints; const relatedValue = (args.object as any)[relatedPropertyName]; return typeof value === 'string' && typeof relatedValue === 'string' && value.length > relatedValue.length; // y...
本人使用的是nestjs框架,参数检验部分使用class-validator进行常见的验证,包括类型检验、值检验等。但当参数为嵌套对象时,如果使用常规的IsObject注解会无法检验到嵌套结构的内部。结构如下: classAddress{@IsString()addressName: string;@IsNumber()addressCode: number; ...
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 '@nest...

In other words, it is the application's responsibility to make sure that one Validator object is not used from more than one thread at any given time, and while the validate method is invoked, applications may not recursively call the validate method....
