How to install

Script tag

<!-- add it after vue.js -->
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/vue-axios-plugin"></script>

CommonJS

npm install --save vue-axios-plugin

And in your entry file:

import Vue from 'Vue'
import VueAxiosPlugin from 'vue-axios-plugin'
 
Vue.use(VueAxiosPlugin, {
  // request interceptor handler
  reqHandleFunc: config => config,
  reqErrorFunc: error => Promise.reject(error),
  // response interceptor handler
  resHandleFunc: response => response,
  resErrorFunc: error => Promise.reject(error)
})

Options

Except axios default request options, vue-axios-plugin provide below request/response interceptors options:

Name	Type	Default	Description
reqHandleFunc	{Function}	config => config	The handler function for request, before request is sent
reqErrorFunc	{Function}	error => Promise.reject(error)	The error function for request error
resHandleFunc	{Function}	response => response	The handler function for response data
resErrorFunc	{Function}	error => Promise.reject(error)	The error function for response error

Usage

Default method in $http, it just contains get and post method:

this.$http.get(url, data, options).then((response) => {
  console.log(response)
})
this.$http.post(url, data, options).then((response) => {
  console.log(response)
})

Use axios original method in $axios, by this, you can use all allowed http methods: get,post,delete,put...

this.$axios.get(url, data, options).then((response) => {
  console.log(response)
})
 
this.$axios.post(url, data, options).then((response) => {
  console.log(response)
})

ChangeLog for v1.3.0

Before v1.3.0, it send a request use application/x-www-form-urlencoded format by default, so it config transformRequest for post request by default, but it is unreasonable. So in v1.3.0, I remove it, all configuration depends on yourself, so you can config the Content-Type and transformRequest depend on your backend service.

TODO

• [] Unit test.

Notice!!!

When you send a request use application/x-www-form-urlencoded format, you need to use qs library to transform post data, like below:

import qs from 'qs'
this.$http.post(url, qs.stringify(data), {
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
  }
}).then((response) => {
  console.log(response)
})

But if the data has properties who's type if object/array, you need convert these properties into JSON string:

import qs from 'qs'
 
function jsonProp (obj) {
  // type check
  if (!obj || (typeof obj !== 'object')) {
    return obj
  }
  Object.keys(obj).forEach((key) => {
    if ((typeof obj[key]) === 'object') {
      obj[key] = JSON.stringify(obj[key])
    }
  })
  return obj
}
 
this.$http.post(url, qs.stringify(data), {
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded',
  },
  transformRequest: [
    function (data) {
      // if data has object type properties, need JSON.stringify them.
      return qs.stringify(jsonProp(data))
    }
  ]
}).then((response) => {
  console.log(response)
})
