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
1 <template>
2 <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>
3 <el-icon class="el-icon--upload"><upload-filled /></el-icon>
4 <div class="el-upload__text">拖拽 / 点击上传文件 ( zip, jpg, png ……)</div>
5 <template #tip>
6 <div class="el-upload__tip">已上传 {{ fileListLength }} 个文件</div>
7 </template>
8 </el-upload>
9 <el-progress :percentage="progress.curr" :color="progress.color" />
10 <el-button type="info" class="btn" @click="removeFile">清空文件</el-button>

1 from loguru import logger 2 from django.http.response import JsonResponse 3 from django.views.decorators.csrf import csrf_exempt 4
5 @csrf_exempt 6 def create_task(request):
7 files = request.FILES.getlist('files')
8 for fit in files:
9 logger.info(f"name: {fit.name} size: {round(fit.size/ 1024 / 1024 / 1024, 5)} G")
10 # 保存文件
11 # with open(f"{os.sep.join(['.', fit['name']])}", mode="wb") as f:
12 # f.write(fit)
13
14 return JsonResponse({"code": 0, "msg": "success"})还有什么更好的方法 ，欢迎大家讨论哇
