import axios from 'axios'
axios.defaults.baseURL = 'http://localhost:8000/'
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'
axios.defaults.headers.common['Authorization'] = 'Bearer ' + localStorage.getItem('token')


export default {
 setToken: function (token) {
  localStorage.setItem('token', token)
  axios.defaults.headers.common['Authorization'] = 'Bearer ' + token
 },
 login: function (param) {
  return axios.post('oauth/token', param)
 },
 index: function (params) {
  return axios.get('api/user/list', {
   params: params
  })
 }
}


config


src/config.js 这里配置登录 oauth 需要的 client_id 和 secret


export default {
 oauth_client_id: 2,
 oauth_secret: ''
}


main.js


src/main.js


import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'

Vue.use(ElementUI)

Vue.config.productionTip = false

new Vue({
 el: '#app',
 router,
 components: { App },
 template: '<App/>'
})


api 接口


主要用到两个接口，一个是 api/oauth/token 登录获取 token 接口，一个获取列表 api/user/list。


第一个接口是用到 laravel oauth，第二个接口直接是一个简单的查询用户列表接口，详细讲会在下一篇文章中讲述。
