Question

我试图添加一个＆＃39;事件＆＃39;模块到我的应用程序使用websockets，但是当我添加模块时，我收到以下错误：

(node:59905) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Request mapping properties not defined in the @RequestMapping() annotation!
(node:59905) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

所有其他模块都已成功加载和映射，只有在我添加EventsModule

时才会发生

所以这里是我的代码：

app.module.ts

@Module({
    modules: [AuthModule, DatabaseModule, UsersModule, TimespansModule, LogsModule, EntitiesModule, EventsModule]
})

events.module.ts

import {EventsComponent} from './events.component';
import {Module} from '@nestjs/common';
@Module({
    controllers: [EventsComponent]
})
export class EventsModule {}

events.component.ts

import {WebSocketGateway, SubscribeMessage, OnGatewayConnection} from '@nestjs/websockets';

@WebSocketGateway({namespace: 'events'})
export class EventsComponent implements OnGatewayConnection {
    handleConnection(client: any) {
        console.log('client connected');
    }

    @SubscribeMessage('stream-received')
    onStream(client, data) {
        console.log('stream received');
    }
}

我无法真正看到此处出现的问题，错误信息对我的帮助也不大。

在events.module.ts

中发现了这个问题

import {EventsComponent} from './events.component';
import {Module} from '@nestjs/common';    
@Module({
    controllers: [EventsComponent]
})
export class EventsModule {}

必须更改控制器=＆gt;部件

import {EventsComponent} from './events.component';
import {Module} from '@nestjs/common';    
@Module({
    components: [EventsComponent]
})
export class EventsModule {}

NestJs websockets UnhandledPromiseRejectionWarning
