我想更改内部方法的实现jest.mock，以便我可以检查我的应用程序对不同边缘情况的反应，所以我这样做了，但是打字稿不允许我模拟firebase.auth().currentUser方法...我在下面显示我的代码和错误

应用程序.js

import firebase from 'firebase/app'\nimport 'firebase/auth'\nimport './Init'\n\nconst App = {\ngetLoggedInUser: () => {\n    const currentUser = firebase.auth().currentUser\n    if (currentUser) {\n      return {\n        email: firebase.auth().currentUser.email,\n        userId: firebase.auth().currentUser.uid,\n        isEmailVerified: firebase.auth().currentUser.emailVerified\n      }\n    } else {\n      return undefined\n    }\n  },\n  isAuthenticated: () => {\n    return !!((App.getLoggedInUser() && App.getLoggedInUser().isEmailVerified === true))\n  },\n}\nexport default App\n

应用程序规范

import myAuthenticationPlugin from 'authenticationPlugin/App'\nimport firebase from 'firebase/app'\n\njest.mock('firebase/app', () => {\n  const userCredentialMock = {\n    user: {\n      sendEmailVerification: jest.fn()\n    }\n  }\n  return …

我已经filesystem使用multer

我的服务器是node，客户端是react.

我在客户端下载和显示保存的文件时遇到问题 react

每当我这样做时，res.download(file)都会因为客户端拒绝连接而引发错误。

我的代码如下：

用户上传映射.js

const mongoose = require("mongoose");

const UserToUploadMapping = new mongoose.Schema({
  userId: {
      type:String,
      required:true
  },
  file: {
    type: Object,
    required: true,
  },
  date: {
    type: Date,
    default: Date.now,
  },
});

module.exports = mongoose.model("UserToUploadMapping", UserToUploadMapping);

上传视频.js

const router = require("express").Router();
const multer = require('multer');
const UserToUploadMapping = require('../models/UserToUploadMapping')

let nameFile = ''
const storage = multer.diskStorage({
    destination:'./Videos',
    filename:(req,file,cb) => {
        console.log(file)
        nameFile = file.originalname + " …

我正在使用Javascript并与我的应用程序Vue集成firebase

场景（已搭建）

• 我有一个sign in用户登录的页面
• 对于要在emailVerified属性中签名的用户应为 true

问题

• 我只能在使用该firebase.auth().createUserWithEmailAndPassword(email, password)方法时发送验证电子邮件

报名方式

signup: async (email, password) => {
    const user = await firebase.auth().createUserWithEmailAndPassword(email, password)
    await user.user.sendEmailVerification()
    return `Check your email for verification mail before logging in`
  },

所需的解决方案

• 我从 firebase console

• 我email作为参数传递或uid该方法应该向用户发送验证电子邮件，以便他们可以验证他们的电子邮件

• 完全废弃该signup方法，因为我不再需要它来发送验证邮件

无论如何，是否可以在不登录的情况下发送验证电子邮件？

这是我当前的模拟，我想createUserWithEmailAndPassword返回firebase.auth.UserCredential，这样我就可以测试它是否在我的中被调用App.ts

应用程序规范

import myAuthenticationPlugin from 'authenticationPlugin/App'
import firebase from 'firebase/app'
jest.mock('firebase/app', () => {
  return {
    auth: jest.fn().mockReturnThis(),
    currentUser: {
      email: 'test',
      uid: '123',
      emailVerified: true
    },

    signInWithEmailAndPassword: jest.fn(),
    createUserWithEmailAndPassword:jest.fn(() => {
      return {
        user:{
          sendEmailVerification:jest.fn(),
        },
      }
    }),
    initializeApp:jest.fn()
  };
});

 describe('Test for signup (email,password)',() => {

    it('createUserWithEmailAndPassword ()',async () => {  //this works
      await myAuthenticationPlugin.signup(email, password)
      expect(firebase.auth().createUserWithEmailAndPassword).toBeCalledWith(email, password)
    })

    it('sendEmailVerification()',async ()=>{
      await myAuthenticationPlugin.signup(email, password)
      const userCredential= await firebase.auth().createUserWithEmailAndPassword(email,password)
      if(userCredential.user!=null){
      expect(userCredential.user.sendEmailVerification).toBeCalled() //this fails as …

如何将set只有值的对象转换为键值对包含相同值的对象key？

let set = new Set()
set.add(a)
set.add(example)
console.log(set)
//OUTPUT {"a", "example"}

//perform some operation to get result below ?

到

{"a":"a","example":"example"}
