不允许使用“POST”方法。 Django 休息框架

问题描述 投票：0回答：1

我不知道，过了一段时间我的 API 部分就停止工作了。 所以我写了我的

apiview
并且它有post功能，但是当我敲一个端点时 我收到不允许 POST 方法的错误，但 API 的其他部分工作正常 所以我肯定有问题
postview
。

项目.urls

from django.contrib import admin
from django.urls import path, include
from rest_framework_simplejwt import views as jwt_views
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),

    path('api/v1/payments/', include('payments.urls')),

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)`

我收到这样的错误：

{
    "detail": "Method \"POST\" not allowed."
}

在 http://127.0.0.1:8000/api/v1/posts/ 端点上，正文位于帖子中。

问题出在 posts.urls 中的 URL。您的 Post_View 用于创建新帖子和查看帖子详细信息。但是，用于创建帖子的 URL (posts/) 和用于查看帖子详细信息的 URL (posts/int:id/) 重叠。这种混乱会导致 Django 阻止 POST 请求，从而导致“Method POST not allowed”错误。

将列表/创建和详细视图的 URL 分开

urlpatterns = [
    path('', Lenta_View.as_view(), name='lenta'),
    path('filtered/<slug:filter>/', Separated_lenta.as_view(), name='lenta'),
    path('posts/', Post_View.as_view(), name='post_list_create'),  # URL for listing and creating posts
    path('posts/<int:id>/', Post_View.as_view(), name='post_detail'),  # URL for post details
    path('profile/', Profile_View.as_view(), name='profile_mine'),
    path('profile/<slug:username>/', Profile_View.as_view(), name='profile_other'),
    path('settings/', Settings_View.as_view(), name='settings'),
    path('like/', Like_View.as_view(), name='like_all'),
    path('like/<int:id>/', Like_View.as_view(), name='like_add'),
    path('search/', Posts_search.as_view(), name='search'),
    path('bookmarks/', Bookmark_View.as_view(), name='bookmark_list'),
    path('bookmarks/<int:id>/', Bookmark_View.as_view(), name='bookmark_add'),
]

修改Post_View以处理不同的HTTP方法：

class Post_View(APIView):
    permission_classes = [IsAuthenticated]
    parser_classes = [MultiPartParser, FormParser]

    def get(self, request, *args, **kwargs):
        id = kwargs.get("id")
        user = request.user
        if id is None:
            return Response({'message': "You haven't provided an ID"}, status=status.HTTP_400_BAD_REQUEST)
        
        post_obj = get_object_or_404(FoodPost, id=id)
        if post_obj.is_public == False and post_obj.created_by != user:
            return Response({'message': "sorry it`s private meal"}, status=status.HTTP_400_BAD_REQUEST)
        ser = FPost_serializer(post_obj, context={'request': request})
        return Response({'data': ser.data}, status=status.HTTP_200_OK)

    def post(self, request):
        data = request.data
        user = request.user

        post_ser = FPost_serializer(data=data, context={'request': request})
        post_ser.is_valid(raise_exception=True)
        post_ser.save(created_by=user)
        return Response({'data': post_ser.data}, status=status.HTTP_201_CREATED)

    def patch(self, request, *args, **kwargs):
        data = request.data
        user = request.user

        id = kwargs.get("id")
        if id is None:
            return Response({'message': "You haven't provided an ID"}, status=status.HTTP_400_BAD_REQUEST)
        
        post_obj = get_object_or_404(FoodPost, id=id)

        if post_obj.created_by != user:
            return Response({'message': "You do not have permission to edit this post"}, status=status.HTTP_403_FORBIDDEN)

        if 'images' in data:
            images = request.FILES.getlist('images')
            for image in images:
                ImagePost.objects.create(post=post_obj, image=image)
        
        post_ser = FPost_serializer(post_obj, data=data, partial=True, context={'request': request})
        post_ser.is_valid(raise_exception=True)
        post_ser.save()
        return Response({'post': post_ser.data, 'message': 'Post updated successfully'}, status=status.HTTP_202_ACCEPTED)
    
    def put(self, request, *args, **kwargs):
        data = request.data
        user = request.user

        id = kwargs.get("id", None)
        if id is None:
            return Response({'message': "You haven't provided an ID"}, status=status.HTTP_400_BAD_REQUEST)
        post_obj = get_object_or_404(FoodPost, id=id)
        com_ser = Comment_serializer(data=data)
        com_ser.is_valid(raise_exception=True)
        com_ser.save(post_obj=post_obj, commented_by=user)
        return Response({'comment': com_ser.data, 'message': 'comment uploaded successfully'}, status=status.HTTP_202_ACCEPTED)
