前端VUE调用后台接口，实现基本增删改查

设置接口请求

作为一个后台，个人一点感想：前端现在都是组件化开发，会看文档基本功能就能实现。

js文件

import request from '@/router/axios'
// 查询
export function queryWordDictList(query) {
  return request({
    url: '/bbs/regtech/wordDict/queryWordDictList',
    method: 'get',
    params: query
  })
}
// 修改
export function updateWordDict(obj) {
  return request({
    url: '/bbs/regtech/wordDict/updateWordDict',
    method: 'put',
    data: obj
  })
}
// 新增
export function saveWordDict(obj) {
  return request({
    url: '/bbs/regtech/wordDict/saveWordDict',
    method: 'post',
    data: obj
  })
}
// 删除
export function deleteWordDict(params) {
  return request({
    url: '/bbs/regtech/wordDict/deleteWordDict',
    method: 'delete',
    params: params
  })
}

VUE数据渲染 + 分页

<template>
  <div>
    <el-row>
      <el-button type="primary" @click="(saveView = true), reset()"
        >新增检测方向</el-button

    <!-- 数据表单 -->
