, the store object can become quite bloated.To solve these problems, Vuex allows us to split the store into modules. Each module has its own state, mutation, action, getter, or even nested submodule-the same way it is split from top to bottom.The last few diagrams make it easy to read the exact wording: Iv. AxiosIs the encapsulated Ajax, which can then be encapsulated according to its own project situation, and then invoked in action. Refer to Https://github.com/mzabriskie/
Today, after discovering that Axios was used in Vue, the data in the then method cannot be read, and always prompts cannot set property ' xxx ' of undefinedAfter finding a lap on the internet, we found a solution.Workaround 1:methods:{ tap:function() { var self=this; Axios.get (' xxxxxx ') . Then (function(result) { self.message= ' hehe ') }) }}Workaround 2:Axios.get (' xxxxxxxxxxx '). Then (result)={
First step: Add a custom field to the routerequireAuth'/repository ', ' repository ', meta: {true,//Add this field, indicating that entering this route is required to log in}, component: RepositoryStep Two:Router. Beforeeach (To, from, next) = { if (to.meta.requireAuth) { //Determines if the route requires login permission if (Store.state.token) { query: {Next ();}Login intercept is this the end of the block? And not.This approach is simply a front-end routing control a

Typically, the front end submits data to the server via a POST request in 4 format, "application/x-www-form-urlencoded" format, "multipart/form-data" format, "Application/json" Format and "Text/xml" format. Often the most common is the "Application/json" format, which is the form of a JSON string.The data you see in the console is this:Sometimes the background needs form form of data in order to parse normally, so the front end needs to change the format when passing through. At first I thought

When you access a route that requires logon rights, you should actually have the user log on again.
In this time, we need to combine the HTTP Interceptor + back-end interface to return the HTTP status code to judge.
Step three: Interceptors (to handle all HTTP requests and responses uniformly, you need to use Axios interceptors.) )
