  • element-ui 后台问题

    1.package.json 中配置 不是所有的都是 npm run dev,npm rn bulid 还要看配置文件

    npm run dev 运行开发环境

    npm run build:prod 运行生产环境 (打包)

    2.elemnt-ui如何将文件流和其他字段一起提交 

    用element-ui框架的https://element.faas.ele.me/#/zh-CN/component/upload  上传组件

    html层

      3.路由拦截器  一些简单的配置

    import axios from 'axios'
    import {
      MessageBox,
      Message
    } from 'element-ui'
    import store from '@/store'
    import {
      getToken,
      setToken
    } from '@/utils/auth'
    
    
    // 创建axios实例
    const service = axios.create({
      baseURL: 'https://ixx.haoqianlei.com/admin/v1',
      // baseURL: process.env.VUE_APP_BASE_API, // url = base url + request url
      // withCredentials: true, // send cookies when cross-domain requests
      timeout: 5000 // request timeout  请求超时
    })
    
    // request interceptor request拦截器  请求拦截
    service.interceptors.request.use(
      config => {
        // do something before request is sent
        if(config.headers.authorization){
          config.headers['Authorization'] = `Bearer ${config.headers.authorization}`
         
          // commit('SET_TOKEN', config.headers.authorization)
          // 登录成功后将token存储在cookie之中
          setToken(config.headers.authorization.slice(7))
          return config
        }
        if (store.getters.token) {
          // let each request carry token
          // ['X-Token'] is a custom headers key
          // please modify it according to the actual situation
          // config.headers['token'] = getToken() // 让每个请求携带token--['X-Token']为自定义key 请根据实际情况自行修改
          // config.headers['X-Requested-With'] = 'XMLHttpRequest';
          config.headers['Authorization'] = `Bearer ${getToken()}` // 让每个请求携带token--['X-Token']为自定义key 请根据实际情况自行修改
         
          // config.headers['user-name'] = store.getters.name
        }
        return config
      },
      error => {
        // do something with request error
        // console.log(error) // for debug
        return Promise.reject(error)
      }
    )
    
    // response interceptor respone拦截器 响应拦截器
    service.interceptors.response.use(
      /**
       * If you want to get http information such as headers or status
       * Please return  response => response
       */
    
      /**
       * Determine the request status by custom code
       * Here is just an example
       * You can also judge the status by HTTP Status Code
       */
      response => {
        const res = response.data;
      
        //拦截响应,做统一处理 当token过期,接口会返回一个可用的token 前端接受以后替换当前token
        if (response.headers.authorization) {
          //设置token
          setToken(response.headers.authorization.slice(7))
        }
        // if the custom code is not 20000, it is judged as an error.
        if (res.code != 200 ) {
        // 状态码
    
          Message({
            message: res.data || 'Error',
          
            type: 'error',
            duration: 5 * 1000
          })
    
          // 50008: Illegal token; 50012: Other clients logged in; 50014: Token expired;
          // 50008:非法的token; 50012:其他客户端登录了;  50014:Token 过期了;
          // if (res.code === 422 || res.code === 401) {
          //   console.log(211)
          //   // to re-login  重新登录
          //   MessageBox.confirm('登录失效', 'Confirm logout', {
          //     confirmButtonText: 'Re-Login',
          //     cancelButtonText: 'Cancel',
          //     type: 'warning'
          //   }).then(() => {
          //     store.dispatch('user/resetToken').then(() => {
          //       // 为了重新实例化vue-router对象 避免bug
          //       location.reload()
          //       console.log(333)
          //     })
          //   })
          // }else{
          //   Message({
          //     // message: res.message || 'Error',
          //     message: 'Error',
          //     type: 'error',
          //     duration: 5 * 1000
          //   })
          // }
    
          return Promise.reject(new Error(res.message || 'Error'))
    
    
        } else {
          return res
        }
      },
      error => {
        console.log('err' + error) // for debug
        Message({
          message: error.message,
          type: 'error',
          duration: 5 * 1000
        })
        return Promise.reject(error)
      }
    )
    
    export default service
    

      4. 修改基础配置

    统一接口路径配置 vue.config.js

    main.js 也要把mock的相关注释掉 防止接口掉错
