Django Rest Framework 不允许使用方法 "POST"

Question

我正在尝试使用 Django Rest Framework JSON API 创建一个 JSON API 兼容的休息服务： https://django-rest-framework-json-api.readthedocs.io/en/stable/index.html

我想我停留在 Django Rest Framework 级别，但我不确定。

我认为 GET 请求有效，但 POST 无效，因为我收到以下响应：

$ curl -H 'Accept: application/vnd.api+json; indent=2' -X POST http://localhost:8000/greeters/
{
  "errors": [
    {
      "detail": "Method \"POST\" not allowed.",
      "source": {
        "pointer": "/data"
      },
      "status": "405"
    }
  ]
}

但是 GET 没问题：

$ curl -H 'Accept: application/vnd.api+json; indent=2' http://localhost:8000/greeters/
{
  "data": {}
}

我查看了其他帖子和教程，似乎我在我的代码中遗漏了一些没有突然出现的东西。希望它会出现在对 Djang 和 Django Rest Framework 有更多经验的其他人身上。

感谢您的宝贵时间:)

这是我的代码：

my_project/urls.py

from django.conf.urls import include
from django.contrib import admin
from django.urls import path, re_path

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path(r'^greeters/', include('greeter.urls')),
]

greeter/urls.py

from django.conf.urls import url, include
from rest_framework import routers
from .views import GreeterViewSet

ROUTER = routers.DefaultRouter()
ROUTER.register(r'^', GreeterViewSet)

urlpatterns = [
    url(r'^', include(ROUTER.urls)),
]

greeter/views.py

from rest_framework import viewsets
from .models import Greeter
from .serializers import GreeterSerializer


class GreeterViewSet(viewsets.ModelViewSet):
    """API endpoints for Greeter"""

    queryset = Greeter.objects.all()
    serializer_class = GreeterSerializer

    # I've tried adding these methods in but none of it worked
    #def perform_create(self, serializer):
    #    serializer.save(owner=self.request.user)

    #def create(self, request):
    #    print('#########create')

    #def post(self, request):
    #    print('#########post')

greeter/serializers.py

from rest_framework import serializers
from .models import Greeter


class GreeterSerializer(serializers.HyperlinkedModelSerializer):
    """Define Greeter serializer"""

    class Meta:
        model = Greeter
        fields = ('message')

greeter/models.py

from django.db import models


class Greeter(models.Model):
    """Define Greeter model"""
    id = models.CharField(
        primary_key=True,
        max_length=200
    )
    message = models.CharField(max_length=200)

更新：

感谢您的帮助。它引导我找到了解决方案。

我删除了 greeter/urls.py 并将所有 url 配置移到了 my_project/urls.py。

from django.conf.urls import include
from django.contrib import admin
from django.urls import path, re_path
from rest_framework import routers
from greeter.views import GreeterViewSet

ROUTER = routers.DefaultRouter()
ROUTER.register(r'greeters', GreeterViewSet)

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path(r'^', include(ROUTER.urls)),
]

它有效，但我仍然想了解如何将所有欢迎程序 url 代码推送到欢迎程序文件夹内的文件中，例如 greeter/urls.py.

我已经打开了一个单独的问题来获得这方面的指导，所以我可以将其标记为已回答。

再次感谢大家的帮助:)

Answer 1

添加一些 API 前缀 到您的 url 包含语句，

urlpatterns = [
    url(<b>r'sample',</b> include(ROUTER.urls)),
]

因此，您的终点将是 /greeters/sample/ for list-api (HTTP GET) 并创建 api (HTTP POST)
