axios is not in vue.
axios is a library, not a third-party plug-in in vue. When using it, you cannot install the plug-in through Vue.use() and need to bind it on the prototype.
axios is a promise-based http library that can run in the browser and node.js. Then the author You Yuxi also decisively gave up the maintenance of its official library vue-resource and directly recommended the axios library.
The role of axios: axios is mainly used to initiate requests to the background, and it also has more controllable functions in the request.
Features
Support Promise API
Interception of requests and responses. To intercept the request, you can filter the request parameters; to intercept the response, you can handle the response exception
Cancel the request. The request can be canceled manually
Use axios in vue
1. Install the axios module
$cnpm install --save axios #安装
2. Reference axios in main.js and link it to the prototype chain. When using a plug-in, it is generally introduced in the entry file main.js, because main.js is the first file to be run by the project:
import Vue from 'vue' import axios from ‘axios’ Vue.prototype.$http = axios
Usage:
3. vue-axios is a small wrapper that integrates axios into Vue.js and can be installed like a plug-in.
$cnpm install --save axios vue-axios #安装
Referring to axios and vue-axios in main.js and using the plug-in through the global method Vue.use() is equivalent to calling the install method:
import Vue from 'vue' import axios from 'axios' import VueAxios from 'vue-axios' Vue.use(VueAxios, axios)
Usage:
$cnpm install --save axios vue-axios
After installing axios and vue-axios, you can see the source code of vue-axios in node_modules/_vue-axios/src/index.js under the Vue project. Using Vue’s plug-in writing method is more in line with Vue’s overall ecological environment. It feels a bit rough to write the prototype chain directly. Unless it is a very low-level implementation, it is not recommended to write this way.

How to separate the front and back end of wordpress
Apr 20, 2025 am 08:39 AM
It is not recommended to directly modify the native code when separating WordPress front and back ends, and it is more suitable for "improved separation". Use the REST API to obtain data and build a user interface using the front-end framework. Identify which functions are called through the API, which are retained on the backend, and which can be cancelled. The Headless WordPress mode allows for a more thorough separation, but it is more cost-effective and difficult to develop. Pay attention to security and performance, optimize API response speed and cache, and optimize WordPress itself. Gradually migrate functions and use version control tools to manage code.
