问题总结

1.django用post传文件，如何接收和下载？

data= request.FILES.get("file")#接收到的数据类型是<class "django.core.files.uploadedfile.InMemoryUploadedFile">
# print(data,type(data)) #<class "django.core.files.uploadedfile.InMemoryUploadedFile">

with open(r"C:Users33101Desktop12新建1111.txt","wb") as p:#这样可以写进文件，不能直接p.write(chunks())
    for chunk in data.chunks():
        p.write(chunk)
