求教 django 如何实现多文件上传

<div class="input-group"> <form action="/manage/upload/" method="post" enctype="application/x-www-form-urlencoded" ><input id="file_upload" name="fileupload" accept="image/png, image/jpeg" multiple="multiple" type="file" value="" /><input id="file_upload" type="button" value="上传" Onclick="FileUpload()"/> </form> </div>

//上传图像 function FileUpload() { $("#prompt").hide(); if ($("#file_upload").val() === ""){ $("#imgprompt").show(); return false; } $("#imgprompt").hide(); $("#loading").show(); var form_data = new FormData(); var file_info =$('#file_upload')[0].files[0]; form_data.append('file',file_info); console.log(form_data); $.ajax({ url:'/manage/upload/', type:'POST', data: form_data, processData: false, contentType: false, success: function(callback) { console.log('ok'); $("#loading").hide(); $("#prompt").show(); } }); }

后端：

def upload(request): if request.method == 'POST': file_obj = request.FILES.get('file') print("file_obj.name", file_obj, file_obj.name) f = open(os.path.join('upload', file_obj.name), 'wb') for chunk in file_obj.chunks(): f.write(chunk) f.close() return HttpResponse('OK')

我是用 restframework，大致上是这样实现的，这不是上传图片，希望对你有帮助

from rest_framework.parsers import FormParser, MultiPartParser
from rest_framework.response import Response
class MultipleFileSerializer(serializers.Serializer):
files = serializes.ListField(child=serializers.FileField())

class UserViewset(ModelViewSet):
serializer_class = UserSerializer
pagination_class = UserPagination
parser_classes = (FormParser, MultiPartParser)

def create(self, request, *args, **kwargs):
print(dir(request))
print(request.FILES)

text = request.FILES['file1'].read() + request.FILES['file2'].read()
return Response(text)

这有什么问题，多个文件就有多个 form 字段
