在NestJS中安装Express中间件(express-openapi-validator)的步骤如下:
npm install -g @nestjs/cli
npm install express-openapi-validator
import { MiddlewareConsumer, Module, NestModule } from '@nestjs/common';
import { OpenApiValidator } from 'express-openapi-validator';
@Module({
imports: [],
controllers: [],
providers: [],
})
export class AppModule implements NestModule {
configure(consumer: MiddlewareConsumer) {
consumer.apply(OpenApiValidator.middleware).forRoutes('*');
}
}
openapi.ts
的文件,并添加以下内容:import { OpenApiValidator } from 'express-openapi-validator';
export const openApiValidator = new OpenApiValidator({
apiSpec: './openapi.json', // 指定OpenAPI规范文件的路径
validateRequests: true, // 启用请求验证
validateResponses: true, // 启用响应验证
});
import { MiddlewareConsumer, Module, NestModule } from '@nestjs/common';
import { openApiValidator } from './openapi';
@Module({
imports: [],
controllers: [],
providers: [],
})
export class AppModule implements NestModule {
configure(consumer: MiddlewareConsumer) {
consumer
.apply(openApiValidator.middleware)
.forRoutes('*');
}
}
现在,你已经成功在NestJS中安装并配置了express-openapi-validator中间件。该中间件将会根据你提供的OpenAPI规范文件对请求和响应进行验证,确保符合规范。
