vue 处理后端返回token

调用后端获取token并保持

handleLogin(){
            this.loginAuthData.params = this.loginData
            this.loginAuthData.params.uuid = this.imageCodeId
            console.log(this.loginAuthData)
            httpClient.post(this.loginAuthData.url,this.loginAuthData.params).then(
                res =>{
                    // console.log(res.data)
                    let token = "Bearer " + res.data.token
                    console.log(token)
                    localStorage.setItem('authorization', token)
                    this.$router.push("/home")
                }
            ).catch(
                res => {
                    this.$message.error({
                        message: res.msg
                    })
                }
            )
        }

添加拦截器

import router from '@/router';
import axios from 'axios';

//新建个axios对象
const httpClient = axios.create({
    validateStatus(status) {
        return status >= 200 && status < 504 // 设置默认的合法的状态
    },
    timeout: 10000   //超时时间10秒
});


httpClient.defaults.retry = 3 // 请求重试次数
httpClient.defaults.retryDelay = 1000 // 请求重试时间间隔
httpClient.defaults.shouldRetry = true // 是否重试

//添加请求拦截器
httpClient.interceptors.request.use(
    config => {
        //添加header
        config.headers['Content-Type'] = 'application/json'
        config.headers['Accept-Language'] = 'zh-CN'
        config.headers['Authorization'] = localStorage.getItem('authorization') // 可以全局设置接口请求header中带token

        if (config.method === 'post') {
            if (!config.data) { // 没有参数时，config.data为null，需要转下类型
                config.data = {}
            }
            // config.data = JSON.stringify(config.data) // qs序列化参数
        }
        return config
    },
    err => {
        //Promise.reject()方法返回一个带有拒绝原因的Promise对象，在F12的console中显示报错
        Promise.reject(err)
    }
);

//添加响应拦截器
httpClient.interceptors.response.use(
    response => {
        if (response.status !== 200) {
            return Promise.reject(response.data)
        } else {
            return response.data
        }
    },
    err => {
        if (err.response && err.response.status === 401){
            localStorage.removeItem('authorization')
            return router.push("/login")
        }
        return Promise.reject(err)
    }
);

export default httpClient;

请求判断是否有token，index.js

//判断token
router.beforeEach((to,from,next) =>{
    if (to.path === '/login'){
        next()
    }else{
        let token = localStorage.getItem('authorization')
        if (token === null || token === ''){
            next('/login')
        }else{
            next()
        }
    }
})
