Question

我正在尝试使用Angular 7和DialogFlow构建聊天机器人，但是当我将其部署到Firebase时，出现错误

src / app / chat / chat.service.ts（18,33）中的
ERROR：错误TS2339：属性类型'{production：boolean;上不存在'dialogflow' }'。

当我运行ng build --prod

时

这是我的chat.service.ts

import { Injectable } from '@angular/core';
import { environment } from '../../environments/environment';

import { ApiAiClient } from 'api-ai-javascript/es6/ApiAiClient';

import { Observable } from 'rxjs/Observable';
import { BehaviorSubject } from 'rxjs/BehaviorSubject';

export class Message {
  constructor(public content: string, public sentBy: string){}
}

@Injectable({
  providedIn: 'root'
})
export class ChatService {

  readonly token  = environment.dialogflow.angularBot;
  readonly client = new ApiAiClient({accessToken: this.token });
  conversation = new BehaviorSubject<Message[]>([]);

  constructor() { }

  update(msg: Message){
    this.conversation.next([msg]);
  }

  converse(msg: string){
    const userMessage = new Message(msg, 'user');
    this.update(userMessage);

    return this.client.textRequest(msg)
      .then(res => {
        const speech = res.result.fulfillment.speech;
        const botMessage = new Message(speech, 'bot');
        this.update(botMessage);
      });
  }

  talk(){
    this.client.textRequest('Who Are You!')
      .then(res => console.log(res));
  }
}

如何进行修复？请帮助我。

Answer 1

对于生产环境，ts将替换为environment.prod.ts

在您的环境中添加angularBot属性。prod.ts

Answer 2

当您运行ng build时，prod angular-cli将使用environment.prod.ts文件，而您的environment.prod.ts文件环境变量没有对话流程，因此会出现错误。

错误TS2339：类型'{production：boolean;类型不存在属性'dialogflow' }'
