(姜戈) 'CommentView'对象没有属性'body'

Question

我一直在尝试使用装饰器模拟注释功能。

import json
import jwt
from django.views           import View
from django.http            import JsonResponse
from functools              import wraps
from django.db.models       import Q
from .models                    import Comment
from account.models   import Account
class CommentView(View):

def login_required(func):
@wraps(func)
def wrapper(request, *args, **kwargs):
# import pdb; pdb.set_trace()
given_token     = json.loads(request.body)['access_token']
decoded_token   = jwt.decode(given_token,None,None)
try:
if Account.objects.filter(username=decoded_token).exists():
return func(request, *args, **kwargs)
return JsonResponse({"message": "username does not exist"})
except KeyError:
return JsonResponse({"message": "INVALID_KEYS"}, status=403)
return wrapper

@login_required
def post(self, request):
print("request ", json.loads(request.body))
data = json.loads(request.body)
Comment.objects.create(
username    = jwt.decode(json.loads(request.body)['access_token']),
content     = data['content'],
)
return JsonResponse({"message":"Comment Created!"}, status=200)
def get(self, request):
return JsonResponse({'comment':list(Comment.objects.values())}, status=200)

我使用名为Httpie的程序来提供JSON POST请求，如下所示：

http -v http://127.0.0.1:8000/comment access_token="eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6ImJlY2sifQ.2unop67pLHOshcGs385GwOvaZZW_J--TRNXyHI3gKNU" content="hello"

令牌没有问题，因为这是在登录视图期间(在另一个应用程序中(期间提供的令牌的确切副本。

以下是"评论"应用中的 models.py 文件。

from django.db                  import models
from account.models   import Account
class Comment(models.Model):
username    = models.ForeignKey(Account, on_delete=models.CASCADE)
content     = models.TextField()
created_time= models.DateTimeField(auto_now_add = True)
updated_time= models.DateTimeField(auto_now = True)
class Meta:
db_table = 'comments'
def __str__(self):
return self.username + ": " + self.content

但是，当我像上面一样使用 Httpie 发送 POST 请求时，我收到此错误：

Internal Server Error: /comment
Traceback (most recent call last):

AttributeError: 'CommentView' object has no attribute 'body'
[20/May/2020 17:35:40] "POST /comment HTTP/1.1" 500 73224

我一直想知道什么会导致错误。我想知道是否没有办法将 json 请求正文放入装饰器中，这将允许我解码令牌(解码版本将是用户名(，以便我可以查看它是否与数据库中的用户名匹配。

非常感谢！！

我解决了问题！

def wrapper(request, *args, **kwargs):

需要
