标签: nestjs-i18n

我想在class-validatorNestjs graphql 的错误消息中使用本地化。但我无法设置翻译后的消息作为响应并将其返回。我尝试了很多解决方案，例如response.status(400).json({....})发送修改后的响应，但这没有用，

我用过了，

 providers: [
{
  provide: APP_FILTER,
  useClass: AllExceptionFilter,
},

],

我的AllExceptionFilter.ts是

import { Catch, ArgumentsHost, BadRequestException } from '@nestjs/common';
import { GqlExceptionFilter, GqlArgumentsHost } from '@nestjs/graphql';
import { I18nService } from 'nestjs-i18n';

@Catch(BadRequestException)
export class AllExceptionFilter implements GqlExceptionFilter {
  constructor(private readonly i18n: I18nService) {}

  async catch(exception: BadRequestException, host: ArgumentsHost) {
   const gqlHost = GqlArgumentsHost.create(host);

    const translatedMessage = await this.i18n.translate('validation.NotEmpty', {
       lang: 'en',
      });
