el-upload通过action指定后端接口，并通过name指定传输的文件包裹在什么变量名中

 <el-uploadclass="upload-demo"dragaction="https://ai.zscampus.com/toy/upload"multiplename="fileList":limit="10"accept=".xlsx, .xls, .txt, .csv, .docx, .pdf, .pptx, .html"><el-icon class="el-icon--upload"><upload-filled /></el-icon><div class="cm-upload-text">点击或拖动文件到此处上传</div><div class="el-upload__tip">支持 .txt, .docx, .csv, .xlsx, .pdf, .html, .pptx 类型文件</div><div class="el-upload__tip">最多支持 10 个文件。单个文件最大 500 MB。</div></el-upload> 

后端代码用FastAPI来写，注意：从request中取出来的变量名要和el-upload中的name指定的变量名保持一致

@router.post("/uploadMaterial")
async def uploadMaterial(fileList: List[UploadFile] = File(...)):writeBytes("./upload",fileList) return {'code':200,"msg":'success'}# 将file写入dirs目录文件
def writeBytes(dirs,fileList):for file in fileList:bytesFile=file.file.read()filename="{}_{}".format(getRandomID(),file.filename)if not os.path.exists(dirs):os.makedirs(dirs)with open(dirs+'/'+ filename, "wb") as f:f.write(bytesFile)
