Python 在/login/”处出现多值DictKeyError；u'；用户名'&引用；

我正在尝试为登录页面构建一个web api。我一直在犯这个错误。虽然我在网上看到过类似和相关的问题，但这些解决方案对我很有帮助。我做得不对的是什么

错误

MultiValueDictKeyError at /login/
"u'username'"

登录

@csrf_exempt
    def my_view(request):
         user = request.POST['username']
         passcode = request.POST['password']
         user = authenticate(request, username=user, password = passcode)
         if user is not None:
             login(request, user)
             return HttpResponse("User logged in")

         else:
             return HttpResponse("User not found")

@csrf_exempt
def my_view(request):
     if request.method == 'POST':
        user = request.POST['username']
        passcode = request.POST['password']
        user = authenticate(request, username=user, password = passcode)
        if user is not None:
            login(request, user)
            return HttpResponse("User logged in")

        else:
            return HttpResponse("User not found")

更新的登录名

@csrf_exempt
    def my_view(request):
         user = request.POST['username']
         passcode = request.POST['password']
         user = authenticate(request, username=user, password = passcode)
         if user is not None:
             login(request, user)
             return HttpResponse("User logged in")

         else:
             return HttpResponse("User not found")

@csrf_exempt
def my_view(request):
     if request.method == 'POST':
        user = request.POST['username']
        passcode = request.POST['password']
        user = authenticate(request, username=user, password = passcode)
        if user is not None:
            login(request, user)
            return HttpResponse("User logged in")

        else:
            return HttpResponse("User not found")

从authenticate函数中删除请求参数

user = authenticate (username=username, password=passcode)

编辑您的视图

@csrf_exempt
def my_view(request):
     user = request.POST.get('username')
     password = request.POST.get('password')
     user = authenticate(username=username, password=password)
     if user is not None:
         login(request, user)
         return HttpResponse("User logged in")
     else:
         return HttpResponse("User not found")

这是文件中的缺陷吗？哪个文件？这意味着在帖子正文中没有名为

username

的参数。我建议你检查一下你的邮递员配置。我已经有用户名和密码了：）希望会有帮助you@Amateur我会仔细检查。并发布带有回溯的完整错误消息。
