ruoyi实现大文件上传

前端：

安装依赖

1.在package.json文件中添加"vue-simple-uploader": "^0.7.4","spark-md5": "^3.0.1"到dependencies中；devDependencies中"node-sass": "^4.9.0",
"sass-loader": "^7.1.0",
npm install jquery --save;
2.并重新npm install

使用依赖

在main.js中使用

//引入
import uploader from 'vue-simple-uploader'
// 全局组件挂载
Vue.use(uploader)

添加页面代码

在这里插入图片描述

添加工具
在这里插入图片描述
bus.js

import Vue from 'vue';

export default new Vue();

config.js

export const ACCEPT_CONFIG = {
    image: ['.png', '.jpg', '.jpeg', '.gif', '.bmp'],
    video: ['.mp4', '.rmvb', '.mkv', '.wmv', '.flv'],
    document: ['.doc', '.docx', '.xls', '.xlsx', '.ppt', '.pptx', '.pdf', '.txt', '.tif', '.tiff','.zip','.7z','.rar'],
    getAll(){
        return [...this.image, ...this.video, ...this.document]
    },
};

添加接口文件
在这里插入图片描述
fileuploader

import request from '@/utils/request'

// 查询公告列表
export function fileMerge(param) {
  return request({
    url: '/你的服务名/background/file/merge',
    method: 'post',
    params: param
  })
}

filelist

import request from '@/utils/request'

// 查询已上传文件列表列表
export function listFilelist(query) {
  return request({
    url: '/你的服务名/background/filelist/list',
    method: 'get',
    params: query
  })
}

// 查询已上传文件列表详细
export function getFilelist(id) {
  return request({
    url: '/你的服务名/background/filelist/' + id,
    method: 'get'
  })
}

// 新增已上传文件列表
export function addFilelist(data) {
  return request({
    url: '/你的服务名/background/filelist',
    method: 'post',
    data: data
  })
}

// 修改已上传文件列表
export function updateFilelist(data) {
  return request({
    url: '/你的服务名/background/filelist',
    method: 'put',
    data: data
  })
}

// 删除已上传文件列表
export function delFilelist(id) {
  return request({
    url: '/你的服务名/background/filelist/' + id,
    method: 'delete'
  })
}

// 导出已上传文件列表
export function exportFilelist(query) {
  return request({
    url: '/你的服务名/background/filelist/export',
    method: 'get',
    params: query
  })
}

在app.vue中将文件的上传组件结果展示组件进行引入使用

<template>
  <div id="app">
    <router-view />
    <theme-picker />
   <!--这是重点 -->
    <global-uploader></global-uploader>
  </div>
</template>

<script>
import ThemePicker from "@/components/ThemePicker";
import globalUploader from '@/views/closedoff/background/fileuploader/globalUploader'
export default {
  name: "App",
  components: { ThemePicker,globalUploader},
    metaInfo() {
        return {
            title: this.$store.state.settings.dynamicTitle && this.$store.state.settings.title,
            titleTemplate: title => {
                return title ? `${title} - ${process.env.VUE_APP_TITLE}` : process.env.VUE_APP_TITLE
            }
        }
    }
};
</script>
<style scoped>
#app .theme-picker {
  display: none;
}
</style>
