Vue Advanced (iii): Axios use detailed HTTP request clients based on Promise, which can be used in both browsers and Node.js. functional features send xmlhttprequests requests in browsers, HTTP requests in Node.js, support Promise APIs, intercept requests and responses, transform request and response data, convert JSON data automatically, and client support protection Ann All free from XSRF attacks; browser support; Install Use Bower: $ Bower Install

Front-end project is done with Vue.js, front-end service URL:http://localhost:8080/Back-end projects are made with node. js, backend service URL:http://localhost:3000/Now the front end is going to call back-end service one of the interfaces, URL:http://localhost:3000/goods, this interface requires 3 parameters (page,pagesize,sort)There are two ways to invoke the back-end interface:1) Call the Axios request back-end service directlyIf you use Axos to i

Workaround 1: (There is a problem with iOS compatibility, it is not recommended)// the JSON format is converted to Formdata format because of the reasons for some interfaces function Json2formdata (jsondata) { varnew urlsearchparams (); for (var in Jsondata) { // traverse each key/value of the JSON object to params.append (Key, Jsondata[key]) ; } return params;}Workaround 2: Use node's QS module, recommendedImport Axios from '

Problem Description: The project created using VUE-CLI, the development address is localhost:8080, needs to access the interface on the localhost:8888. Analysis Reason: Access between different domain names requires Cross-domain to be properly requested. There are many ways to cross domains, usually requiring background configuration.However, the project created by VUE-CLI can use the Node.js Proxy server directly to implement Cross-domain requests. Solution: First,

Summary Vue uses Axios for HTTP communication, similar to the role of Jquery/ajax, similar to the role of angular HTTP, Axios powerful, easy to use, is an excellent HTTP software, the purpose of this article is to share the key points of Axios source code analysis, The details of the source code are not intended to be thoroughly analyzed from beginning to en

Front desk is vue+element, the background is spring boot set up the SSM project, now the demand is that the front form needs to pass the relevant Java bean to the background, because not familiar with the pure front and back end separation, so using the traditional jsp+vue+element Through a variety of methods and Baidu, or 400 background parsing error, or passed the data are null, because the page other methods are used Axios, so do not want to use Aj

Because only the get and post methods can be used in Axios to make request data cross-domain Access data without JSONP and so on if you want to use Axios to do cross-domain access directly it is not possible to configure the agent why do I need to configure the agent? The reason is because the client is requesting that the data on the server has cross-domain problems and that the servers and servers can req

Objective: Vue originally had an official recommended Ajax plugin Vue-resource, but since Vue update to 2.0, Yu Yuxi announced the stop update Vue-resource, and recommended the use of Axios, more and more Vue projects, have chosen Axios to complete the AJ Ax request, and large projects use VUEX to manage data Previously used is the Vue-resource plug-in, after the main import file introduced import Vueresour

Useful in our projects: FetchHave a direct use, also have their own packaging after use; Vue-resourceWhen Vue1 is used, the method is abstracted out, it is always necessary to pass this to the method. $http, feel is a super uncomfortable design, in vue2 time discarded; AxiosThis is a very good design, it is borrowed angularjs the concept of HTTP + httpbackend, the unit test,mocking data is more convenient to replace a false backend can, and code deduction comments, about 500 lin

Problem ScenarioThe scenario is simple, which is a normal Axios POST request:axios({ headers: { ‘deviceCode‘: ‘A95ZEF1-47B5-AC90BF3‘ }, method: ‘post‘, url: ‘/api/lockServer/search‘, data: { username, pwd }})Backstage said not received your communication.This is a bit strange, I looked at the browser request information is OK, parameters are there, and before this with Axios also does not
