封装的js文件如下：
/* 用于修改 axios 的一些公用配置，具体参看文档 */
import axios from 'axios'
import store from '@/store/index.js'
import qs from 'qs'
import { isJSON } from '@/utils/utils'
import { getToken } from '@/common/js/cache'
// import { ROOT_URL } from '@/configs/config'
axios.defaults.transformRequest = (data, headers) => {
if (store.getters.token) {
headers['accesstoken'] = getToken() // 让每个请求携带自定义token 请根据实际情况自行修改
}
if (headers['Content-Type'] === 'application/x-www-form-urlencoded' && data && Object.prototype.toString.call(data) === '[object Object]') {
data = qs.stringify(data)
}
return data
}
const newAxios = axios.create({
timeout: 1500000
})
newAxios.interceptors.request.use(config => {
return config
}, err => {
return Promise.reject(err)
})
newAxios.interceptors.response.use(response => {
const accesstoken = response.headers.accesstoken
// debugger
const res = isJSON(response.data) ? response.data : JSON.parse(response.data)
if (accesstoken && isJSON(res.data)) {
res.data.accesstoken = accesstoken
}
return response.data
}, err => {
if (err.code === 'ECONNABORTED' && err.message.indexOf('timeout') !== -1) {
// Message.error('请求超时。。。')
console.log('请求超时。。。')
}
console.log(err)
return Promise.reject(err)
})
export function request (_param) {
const {
method = 'get',
// `responseType` 表示服务器响应的数据类型，可以是 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream'
responseType = 'json', // 默认的
headers = {},
url = '',
params,
data,
...otherData
} = _param
if (!url) {
return new Promise((resolve, reject) => {
reject(new Error('url is null'))
})
}
const _method = method.toLowerCase()
if (_method === 'get') {
return newAxios({
responseType,
url,
headers,
method,
params: params || data || otherData
})
}
if (_method === 'post' || _method === 'delete' || _method === 'put') {
if (!headers.hasOwnProperty('Content-Type')) {
headers['Content-Type'] = 'application/x-www-form-urlencoded'
}
if (params && data) {
return newAxios({
responseType,
url,
headers,
method,
params,
data
})
} else {
const { start, limit, ...resetData } = otherData
return newAxios({
responseType,
url,
headers,
method,
params: params || { start, limit },
data: data || resetData
})
}
}
}
export default newAxios
接下来就是其他文件作为公用的请求进行使用了，以登陆为例子：
import { request } from '@/common/js/ajax'
import MD5 from 'crypto-js/md5'
import { getToken } from '@/common/js/cache'
export function login ({ userNo, password }) {
const url = '/v1/security/logon'
return request({
url,
method: 'post',
data: {
userNo,
password: MD5(password).toString()
}
})
}
