See the complete approach/src/router.js
Among them, to.meta we customize the data, including the fields we just defined requireAuth . Use this field to determine whether the route requires logon permissions. If required, the current app does not have tokens, then jump to the login page and sign in. Jump to destination route after successful login.Login intercept is this the end of the block? And not. This approach is simply a front-end routing control and does not really prevent
Refer to the code of this encapsulation API to understand the problem with basePlus an understanding of ' ${base/login} ' below encapsulates Axios request for invocation Let base = "Export Const Requestlogin = params + = {return Axios.post (' ${base}/login ', params).

invalid data, key is {"FirstName": "Fred", "LastName": "Flintstone"} , value is empty. To use the application/x-www-form-urlencoded format, data conversion is required, although there are two ways URLSearchParams and qs two ways. I prefer qs库 the way to use the code as follows:axios.interceptors.request.use((req) => { if (req.method === ‘post‘) { req.data = qs.stringify(req.data); } return req;}, (error) => Promise.reject(error));When you use
Axios defaults to a method that does not have a JSONP cross-domain request. It is generally a popular practice to put the cross-domain in the background to resolve, that is, the background developers add cross-domain header information.For example, in JavaHeader,response.setheader ("Access-control-allow-origin", "www.allow-domain.com")However, many times, the background for some reasons do not want to modify or have written JSONP interface needs to ad

In the Vue project, the list data needs to use the QQ music interface data, but the direct request does not have the host and the referer limit, needs to adopt the way of the back-end proxy. With Axios and Node Express, after implementation in Dev-server.js, restart the project, resulting in interface 404. The code is as follows: After careful examination, the code is no problem, so in apirouts Console.log () print information, run no printing inform
Axios with the traditional function method, this is not an instance of Vue. To change the data in the Vue, you must use the arrow method. (This in the Arrow method refers to the up-level this)Let vm= thenew Vue ({ el:' #app ', created () {this. InitData (); } , methods: { InitData () { axios.get (' Db.json '). Then (theres=> {this . products=Res.data;} , e
