This article mainly introduces the example code of vue2.5.2 using http request to obtain static json data. Friends who need it can refer to it
1. Configure build/webpack.dev.conf.js
// 获取静态json数据 const express = require('express') const app = express() const apiServer = express() const bodyParser = require('body-parser') apiServer.use(bodyParser.urlencoded({ extended: true })) apiServer.use(bodyParser.json()) const apiRouter = express.Router() const fs = require('fs') apiRouter.route('/:apiName') .all(function (req, res) { fs.readFile('./db.json', 'utf8', function (err, data) { if (err) throw err var data = JSON.parse(data) if (data[req.params.apiName]) { res.json(data[req.params.apiName]) } else { res.send('no such api name') } }) }) apiServer.use('/api', apiRouter); apiServer.listen(8081, function (err) { if (err) { console.log(err) return } console.log('Listening at http://localhost:' + (8081) + '\n') })
2. Create a new db.json
{ "getNewsList": [ { "id": 1, "title": "新闻条目1新闻条目1新闻条目1新闻条目1", "url": "http://starcraft.com" }, { "id": 2, "title": "新闻条目2新闻条目2新闻条目2新闻条目2", "url": "http://warcraft.com" }, { "id": 3, "title": "新闻条3新闻条3新闻条3", "url": "http://overwatch.com" }, { "id": 4, "title": "新闻条4广告发布", "url": "http://hearstone.com" } ], "login": { "username": "yudongdong", "userId": 123123 }, "getPrice": { "amount": 678 }, "createOrder": { "orderId": "6djk979" }, "getOrderList": { "list": [ { "orderId": "ddj123", "product": "数据统计", "version": "高级版", "period": "1年", "buyNum": 2, "date": "2016-10-10", "amount": "500元" }, { "orderId": "yuj583", "product": "流量分析", "version": "户外版", "period": "3个月", "buyNum": 1, "date": "2016-5-2", "amount": "2200元" }, { "orderId": "pmd201", "product": "广告发布", "version": "商铺版", "period": "3年", "buyNum": 12, "date": "2016-8-3", "amount": "7890元" } ] } }
3. Access through localhost:8081/api/getNewsList
4. How to get it on the page
##
export default { data() { newsList: [] }, created: function(){ this.$http.get('api/getNewsList').then((res)=> { this.newsList = res.data },(err)=> { console.log(err); }) } }The above is what I compiled for everyone. I hope it will be helpful to everyone in the future. Related articles:

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
