没有JSON对象可以被解码 - Django的request.body

Question

我张贴从智能手机的评论使得Web服务，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) 

每当我检查，对本地IT工作，但在服务器端它给了我下面的错误

我无法弄清楚它为什么给 异常值：无JSON对象可以解码

Answer 1

我猜想，您正在使用django-rest-framework。所以，你不必做json.loads()，becasue django-rest-framework提供request.data为POST请求和request.query_params为GET请求，JSON格式已经被解析。

所以我认为这应该适合你。

@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)
