def upload_view(request):
	    if request.method == 'GET':
	        return render(request,'upload.html')
	    file = request.FILES.get('asd') # 获得文件的对象
	    filename = file.name #获得文件的名字
	    content = file.read() # 将内容读到内存
	    import os
	    BASE_DIR = os.path.join(os.getcwd(),'imgs')
	    if not os.path.exists(BASE_DIR):
	        os.makedirs(BASE_DIR)
	    with open(os.path.join(BASE_DIR,filename),'wb') as fw:
	        fw.write(content)
	    return HttpResponse('上传成功')

def upload_view(request):
	    if request.method == 'GET':
	        return render(request,'upload.html')

	    file = request.FILES.get('asd') # 获得文件的对象
	    filename = file.name #获得文件的名字
	    with open(os.path.join(BASE_DIR,filename),'wb') as fw:
	        # 读取大文件 需要分段读取（写完之后再读）
	        for chunk in file.chunks(2048):
	            fw.write(chunk)
