使用插槽技术实现删除功能 使用工具idea，Visual Studio Code

第一步：拿id

 第二步：测试有没有拿到id，拿到id后进行下一步

 

第三步：去后端编写Controller，因为我的实体类，mapper和service是自动生成的所以没有sql语句，可以直接编写Controller

 第四步返回前端：编写前端的js

在技术里面引入的request是：

import axios from 'axios'
import { MessageBox, Message } from 'element-ui'
import store from '../store'
//import { getToken } from '@/utils/auth'

// create an axios instance 创建一个实例
const service = axios.create({
  
 baseURL: "http://localhost:8888",//process.env.VUE_APP_BASE_API, // url = base url + request url
  // withCredentials: true, // send cookies when cross-domain requests
  timeout: 50000 // request timeout超时时间
})
// request interceptor
service.interceptors.request.use(
  config => {
    // 在请求头提供token
    const token = store.getters.token || window.sessionStorage.getItem('token')
    if (token) {
        //每次请求都会携带token
      config.headers.Authorization = token
    }
    return config
  },
  error => {
    console.log(error) // for debug
    return Promise.reject(error)
  }
)
// request interceptor 做登录的
// service.interceptors.request.use(
//   config => {
//     // do something before request is sent

//     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['X-Token'] = getToken()
//     }
//     return config
//   },
//   error => {
//     // do something with request error
//     console.log(error) // for debug
//     return Promise.reject(error)
//   }
// )

// response interceptor
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

    // if the custom code is not 20000, it is judged as an error.
    if (res.code !== 200) {//成功吗200
      Message({
        message: res.message || 'Error',
        type: 'error',
        duration: 5 * 1000
      })

      // 50008: Illegal token; 50012: Other clients logged in; 50014: Token expired;
      if (res.code === 50008 || res.code === 50012 || res.code === 50014) {
        // to re-login
        MessageBox.confirm('You have been logged out, you can cancel to stay on this page, or log in again', 'Confirm logout', {
          confirmButtonText: 'Re-Login',
          cancelButtonText: 'Cancel',
          type: 'warning'
        }).then(() => {
          store.dispatch('user/resetToken').then(() => {
            location.reload()
          })
        })
      }
      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

第五步：去你要删除的页面引入刚刚编写的js

第六步：编写方法并判断是否删除

第七步：实现删除功能
