结合使用Cypress和Express

问题描述

我正在尝试实现一个将截屏的端点。

我的package.json

{
  "name": "cy-screenshot-api","version": "1.0.0","description": "Screenshot API using Cypress","main": "app.js","scripts": {
    "start": "node app.js","dev": "nodemon app.js","test": "echo \"Error: no test specified\" && exit 1"
  },"author": "","license": "ISC","dependencies": {
    "express": "^4.16.4","nodemon": "^2.0.4","cypress": "^5.1.0"
  }
}

我的app.js

const express = require('express')
const cy = require('cypress')
const app = express()
const port = 3000

app.get('/',(req,res) => {
  res.send('Hello World!')
  cy.visit('https://example.cypress.io').get('body').screenshot()
})

app.listen(port,() => console.log(`Server accessible by http://localhost:${port}`))

错误
