python - django 中间件使发布请求为空

Question

如果我使用中间件，我发送的发布数据将被捕获为空白，如果我从 settings.py 文件中删除中间件，它会返回发布数据。我究竟做错了什么。

这是我删除中间件时的正确结果

这是中间件代码:这里的缩进可能是错误的

class CheckAuthorization(object):
def process_request(self, request):
    getKey = request.POST.get('authKey')
    token = request.POST.get('token')
    full_path = request.get_full_path()
    if getKey is not None and getKey != '' and full_path != "/users/splash/":
        try:
            auth = TblAutherization.objects.get(secret_key = request.POST.get('authKey'))
        except TblAutherization.DoesNotExist:
            response = JsonResponse({'Status':'Error','Response code': 107,'Message':full_path})
            return HttpResponse(response, content_type='application/json')
    else:
        return None
    if token is not None and token != '' and  'settoken' in request.session and full_path != "/users/splash/":
        try:
            auth = TblLoginAuth.objects.get(token = request.POST.get('token'))
        except TblLoginAuth.DoesNotExist:
            response = JsonResponse({'Status':'Error','Response code': 107,'Message':'Invalid Request'})
            return HttpResponse(response, content_type='application/json')
    else:
        return None 

views.py

def splash(request):
if request.method == 'POST':
    try:
        appId = request.POST.get('appId')
    except: 
        return Response({'Status':appId})

    gcmToken = request.POST.get('gcmToken')
    deviceType = request.POST.get('deviceType')
    userId = request.POST.get('userId')
    loginStatus = request.POST.get('loginStatus')
    appType=request.POST.get('appType')
    return Response({'appId':appId,'gcmToken':gcmToken,'deviceType':deviceType})
else:
    return Response({'appId':appId,'gcmToken':gcmToken,'deviceType':deviceType})

它甚至没有进入，除非我使用 try except

我在实现日志记录中间件时遇到了同样的问题。如果您尝试在中间件中访问它，Django 似乎会从 POST dict 中删除所有数据。不知道这是错误还是功能，但我提出了临时解决方案:您可以使用 request.body 获取数据。

body = request.body.decode('utf-8')  # in python 3 json.loads only accepts unicode strings 
body = json.loads(body)
content = body['content']
