Python 无法解码JSON对象-Django request.body

我正在做一个网络服务，从智能手机上发布评论，下面是我的代码

@api_view(['POST'])
def comment_post(request,newsId=None):
    data = json.loads(request.body)
    responseData= dict({
       "result": list()
       })
    if(newsId):
        commentNews  = models.Comments.objects.create()
        commentNews.comment_description = data.get('comment_description').strip()
        commentNews.like_count = int(data.get('like_count'))
        commentNews.user_name = data.get('user_name').strip()
        commentNews.user_email_id = data.get('user_email_id').strip()
        commentNews.parent_comment = data.get('parent_comment').strip()
        commentNews.save()
        subscribed_user = models.SubscribedUsers.objects.create(username=data.get('user_name').strip(),email=data.get('user_email_id').strip())
        news = models.News.objects.get(id=int(newsId))
        news.comments.add(commentNews)
        data ={
         'status':'success'
         }
    else:
        data ={
        'status':'failure'
        }
    responseData['result'].append(data)
    return Response(responseData,status=status.HTTP_200_OK) 

每当我在本地检查它时，它就会工作，但在服务器端，它会给我以下错误

ValueError at /service/comment_post/369

我不明白为什么会这样

---

异常值：无法解码任何JSON对象

我猜，您使用的是

django rest框架

。因此，您不必执行

json.loads（）

，因为

django rest framework

为

POST

请求和

request提供
data
。查询
GET
请求的参数，已经以json格式解析

所以我认为这应该对你有用

@api_view(['POST'])
def comment_post(request,newsId=None):
responseData= dict({
   "result": list()
   })
if(newsId):
    commentNews  = models.Comments.objects.create()
    commentNews.comment_description = request.data.get('comment_description').strip()
    commentNews.like_count = int(request.data.get('like_count'))
    commentNews.user_name = request.data.get('user_name').strip()
    commentNews.user_email_id = request.data.get('user_email_id').strip()
    commentNews.parent_comment = request.data.get('parent_comment').strip()
    commentNews.save()
    subscribed_user = models.SubscribedUsers.objects.create(username=request.data.get('user_name').strip(),email=request.data.get('user_email_id').strip())
    news = models.News.objects.get(id=int(newsId))
    news.comments.add(commentNews)
    data ={
     'status':'success'
     }
else:
    data ={
    'status':'failure'
    }
responseData['result'].append(data)
return Response(responseData,status=status.HTTP_200_OK) 

要了解更多信息，请阅读
我认为您不必在rest框架中执行json.loads bcz，您可以通过json格式的request.data进行访问。请尝试将其用于本地，但每当我将其发布到服务器上时，它都不起作用。下面显示错误类型/service/comment\u post/369 int（）参数必须是字符串或数字，而不是“NoneType”请求方法：post请求URL:Django版本：1.9.5异常类型：TypeError异常值：int（）参数必须是字符串或数字，非“非类型”异常位置：/var/www/vhosts/newskabari.com/newskabari\u-dev/app/mediafuser/apps/mediafuser/views/restViews/restViews.py在comment\u post，request.data中的第167行给出{“comment\u description”：“yyyy”，“like\u count”：“1”，“用户名”：“ooo”，“用户电子邮件id”：iiii@webmail.com",      “家长意见”：“1”}正如我为itLet us发布的。
