Django获得数据
  1. 属性介绍
  2. request.META
  3. request.scheme
  4. request.path
  5. request.encoding
  6. request.session
  7. request.COOKIES
  8. request.method
  9. 获取数据的方法
  10. request.body
  11. request.data
  12. name = request.GET.get("name")
  13. name = request.POST.get("name")
  14. request.FILES.get('pic')
  15. FILES 只有在请求的方法为POST 且提交的<form> 带有enctype="multipart/form-data" 的情况下才会包含数据。否则，FILES 将为一个空的类似于字典的对象
  1. def ttttt(request):
  2.     # 获取上传文件的处理对象
  3.     try:
  4.         pic = request.FILES.get('pic')
  5.         method = request.method
  6.         print(method)  # POST GET
  8.         body = request.body
  9.         print(body)
  11.         path = request.path  # http://127.0.0.1:8000/cockpit/ttttt/?AA=aa&BB=bb
  12.         print(path)  # /cockpit/ttttt/
  14.         full_path = request.get_full_path()
  15.         print(full_path)  # /cockpit/ttttt/?AA=aa&BB=bb
  17.         ajax = request.is_ajax() # 判断是不是ajax发送的请求
  18.         print(ajax)  # False
  20.         cookies = request.COOKIES
  21.         print(cookies)  # {'cookie1': '11', 'cookie2': '22'}
  23.         cookie1 = request.COOKIES.get("cookie1")
  24.         print(cookie1)  # '11'
  26.         meta = request.META
  27.         # print(meta)  # 好多好多参数，看下方
  29.         get = request.GET
  30.         print(get)  # <QueryDict: {'AA': ['aa'], 'BB': ['bb']}>
  32.         AA = request.GET.get("AA", None)  # http://127.0.0.1:8000/cockpit/ttttt/?AA=aa&BB=bb 不管get请求还是post请求都可以拿到
  33.         print(AA)  # aa
  35.         CC = request.POST.get("aas", None)
  36.         print(CC)  # cc
  38.         return JsonResponse({"code": 20000, 'message': '删除成功'})
  39.     except Exception as e:
  40.         return JsonResponse({"code": 20001, 'error': str(e)})
