Detailed explanation of dynamic Axios configuration steps and axios steps
Preface
Previously, Vue-resource was used as the project ajax library when I was writing a vue project. One day in July, especially the updates on Weibo showed that the ajax library should be generic, the technical support for vue-resource is abandoned, and axios is recommended.
We recommen

This article brings you the content is about Vue based on the Vuex and Axios interceptors to achieve loading effect and Axios installation configuration, there is a certain reference value, the need for friends can refer to, I hope to help you.

Creating Projects with VUE-CLI scaffolding
Enter Project installation Vuex, Axios (npm install vuex,
Sometimes need to write a long path, annoying, so you can write the same operation together, if you need to modify, you can modify the Axios request

Application scenarios:
1. parameters included in each request, such as tokens and timestamps.
2. Determine the returned status, such as whether the token has expired.
The Code is as follows:

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 '
Vue Advanced (iii): Axios use detailed

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

2. Run install
After the creation is complete, go to the directory and execute npm install to download all dependent items. This process may take several minutes depending on the network environment. You can have a cup of tea in the toilet. As shown in

4. text/xml
The remaining encoding format is text/xml, which I have never used.
Solution
Since we know that the axios post method uses the application/json format to encode data by default, there are two solutions: one is to change the method of receiving parameters in the background,
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,
axiosIs the current popular Promise Network Request library, in the browser side he xhr created Ajax requests by way. In the node environment, http create a network request through the library.axiosProvides a rich set of configurations, here is the basic configuration method I usually use in my work.Because I am working vue with development, the following code defaults to the environment vue-cli .Create a

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
