vue3 + element-plus 的 upload + axios + django 实现文件上传并保存功能
作者:卫龙吖
这篇文章主要介绍了vue3 + element-plus 的 upload + axios + django 文件上传并保存,本文通过实例代码给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友参考下吧
之前在网上搜了好多教程,一直没有找到合适自己的,要么只有前端部分没有后端,要么就是写的不是很明白。所以还得靠自己摸索出来后,来此记录一下整个过程。
- 其实就是不要用默认的 action,要手动实现上传方式 http-request,然后再传给后端进行各种操作了
- 这里隐藏了文件展示列表
- 展示了上传文件的个数
- 文件去重上传
- 也对上传文件的格式做了限制
- 在点击创建的时候 progress 会随着上传进度动态变化
环境安装什么的就不讲了,直接上代码好吧,这个是样式图
这是vue3代码
<template> <el-upload class="upload-demo form-item" v-model:file-list="fileList" drag multiple :http-request="httpRequest" :show-file-list="false" auto-upload="false" :accept=upload_accept> <el-icon class="el-icon--upload"><upload-filled /></el-icon> <div class="el-upload__text">拖拽 / 点击上传文件 ( zip, jpg, png ……)</div> <template #tip> <div class="el-upload__tip">已上传 {{ fileListLength }} 个文件</div> </template> </el-upload> <el-progress :percentage="progress.curr" :color="progress.color" /> <el-button type="info" class="btn" @click="removeFile">清空文件</el-button> <el-button type="primary" class="btn" @click="create">创建</el-button> </template> <script setup lang="ts"> import { ref, watch } from "vue"; import http from "@/utils/axios/index"; import { UploadFilled } from '@element-plus/icons-vue'; import { ElMessage } from 'element-plus'; const public_elmsg_success = (msg: string) => { ElMessage({ type: 'success', duration: 1000, showClose: true, message: msg }) }; const public_elmsg_warning = (msg: string) => { ElMessage({ type: 'warning', duration: 1000, showClose: true, message: msg }) }; const public_elmsg_error = (msg: string) => { ElMessage({ type: 'error', duration: 1000, showClose: true, message: msg }) }; const upload_accept = ref(".JPG,.PNG,.JPEG,.PCD,.MP4,.AVI,.DAT,.DVR,.VCD,.MOV,.SVCD,.VOB,.DVD,.DVTR,.DVR,.BBC,.EVD,.FLV,.RMVB,.WMV,.MKV,.3GP,.ZIP"); // 限制了上传文件的格式 大写后缀 const upload_lower = ref(upload_accept.value.split(',').map((item: any) => item.toLowerCase())); // 限制上传文件的格式 小写后缀 const fileList: any = ref([]); const fileList1: any = ref([]); const fileListLength = ref(0); const progress = ref({ "curr": 0, "color": "orange" }) watch(fileList1, (newVal, oldVal) => { console.log(newVal, oldVal) fileListLength.value = newVal.value; fileListLength.value = newVal.length; }, { immediate: true, deep: true }); const httpRequest = (options: any) => { let nameList: Array<any> = []; fileList1.value.forEach((item: any) => { nameList.push(item.name); }); const file_suffix = options.file.name.split("."); if (!upload_lower.value.includes(`.${file_suffix[file_suffix.length - 1]}`)) { public_elmsg_warning(`文件 ${options.file.name} 格式不正确`); return; } if (nameList.includes(options.file.name)) { } else { fileList1.value.push(options.file) } fileList.value = fileList1.value; } const removeFile = () => { fileList.value = []; fileList1.value = []; progress.value.curr = 0; } const create = () => { const formData = new FormData() fileList1.value.forEach((file: any) => { console.log(file) formData.append('files', file) }) http.post("task/create/", formData, { headers: { "Content-Type": "multipart/form-data" }, onUploadProgress(progressEvent: any) { progress.value.curr = Math.round((progressEvent.loaded * 100) / progressEvent.total) if (progress.value.curr == 100) { progress.value.color = 'green' } else { progress.value.color = 'orange' } }, }).then((res: any) => { if (res.code == 0) { public_elmsg_success("任务创建成功") } else { public_elmsg_error(res.msg) } } ); } </script>
v3版本的 djagno 代码
from loguru import logger from django.http.response import JsonResponse from django.views.decorators.csrf import csrf_exempt @csrf_exempt def create_task(request): files = request.FILES.getlist('files') for fit in files: logger.info(f"name: {fit.name} size: {round(fit.size/ 1024 / 1024 / 1024, 5)} G") # 保存文件 # with open(f"{os.sep.join(['.', fit['name']])}", mode="wb") as f: # f.write(fit) return JsonResponse({"code": 0, "msg": "success"})
