Django之视图层

from django.http import JsonResponse
import json

def xxx(request):
    user_dict = {‘username‘:‘你好帅，我好喜欢!‘,‘password‘:‘123‘}
    # json_str = json.dumps(user_dict,ensure_ascii=False)
    # return HttpResponse(json_str)
    l = [1,2,3,4,5,6,7,8,9,]
    # return JsonResponse(user_dict,json_dumps_params={‘ensure_ascii‘:False})
    return JsonResponse(l,safe=False)  # 序列化非字典格式数据 需要将safe改为False

def upload(request):
    if request.method == ‘POST‘:
        #获取用户上传的文件数据
        print(request.FILES)
        file_obj = request.FILES.get(‘myfile‘)  #可以把file_obj看作是一个文件句柄
        print(file_obj.name) #获取文件名
        with open(file_obj.name,‘wb‘)as f:
            for line in file_obj:
                f.write(line)
                
    return render(request,‘upload.html‘)
