javascript - kuzzle/react native - 无法从 BaseController 继承类

Question

我正在尝试扩展 KUZZLE JavaScript SDK，以便调用 kuzzle 服务器上的一些 Controller ，这些 Controller 是通过插件实现的。我正在遵循该指南:add controller

这是我的 Controller ，它从 BaseController 扩展而来:

const { BaseController } = require('kuzzle-sdk');

export class UserController extends BaseController {
  constructor (kuzzle) {
  super(kuzzle, 'plugins-user/userController');
}

/**
 * Method to call the action "CreateAccount" on the UserController
 * @param {*} user 
 */
 async createAccount(user) {
   const apiRequest = {
     action: 'new',
     body: {
       user
     }
 };

 try {
    const response = await this.query(apiRequest);
    return response.result.user;
 }
 catch (error) {
    //Manage errors
 }
}
}

这里是我指定 Controller 的地方，以便在创建单例时在应用程序中进一步使用它。

const {UserController} = require('./UserController');
const { Kuzzle, WebSocket } = require('kuzzle-sdk');

class KuzzleService {

static instance = null;
static async createInstance() {
    var object = new KuzzleService();
    object.kuzzle = new Kuzzle(
        new WebSocket('localhost'),{defaultIndex: 'index'}
    );
    object.kuzzle.useController(UserController, 'user');

    await object.kuzzle.connect();
    const credentials = { username: 'admin', password: 'pass' };
    const jwt = await object.kuzzle.auth.login('local', credentials);
    return object;
}

static async getInstance () {
    if (!KuzzleService.instance) {
        KuzzleService.instance = await KuzzleService.createInstance();
    }
    return KuzzleService.instance;
}

  }
 export default KuzzleService;

不知何故我收到以下错误:

Controller 必须继承自基础 Controller

进口有问题吗？

我已经找到了解决该问题的方法。首先，我使用的不是最近发布的 kuzzle SDK 的正确版本 (6.1.1)，其次， Controller 类必须导出为默认:

const { BaseController } = require('kuzzle-sdk');

 export default class UserController extends BaseController {
   constructor (kuzzle) {
     super(kuzzle, 'plugins-user/userController');
 }

 /**
 * Method to call the action "CreateAccount" on the UserController
 * @param {*} user 
 */
 async createAccount(user) {
    const apiRequest = {
      action: 'new',
      body: {
        user
      }
    };

   try {
     const response = await this.query(apiRequest);
     return response.result.user;
   }
   catch (error) {
     //Manage errors
    }
 }
 }

然后 UserController 需要以这种方式导入:

import UserController from './UserController.js'

然后，按照文档中的说明，我们只需将 kuzzle 对象以这种方式注入(inject)到 Controller 中:

kuzzle.useController(UserController, 'user');
