Django REST 框架中的 405“不允许使用方法 POST”答案

【问题标题】：405 “Method POST is not allowed” in Django REST frameworkDjango REST 框架中的 405“不允许使用方法 POST”
【发布时间】：2019-05-04 10:32:37
【问题描述】：

我正在使用 Django REST 框架来实现 Get、Post api 方法，并且让 GET 正常工作。但是，在发送 post 请求时，它会在下面显示 405 错误。我在这里错过了什么？

405 Method Not Allowed
{"detail":"Method \"POST\" not allowed."}

通过 post 方法发送此正文

{
    "title": "abc"
    "artist": "abc"
}

我有

api/urls.py

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

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path('api/(?P<version>(v1|v2))/', include('music.urls'))
]

音乐/urls.py

from django.urls import path
from .views import ListSongsView


urlpatterns = [
    path('songs/', ListSongsView.as_view(), name="songs-all")
]

音乐/views.py

from rest_framework import generics
from .models import Songs
from .serializers import SongsSerializer


class ListSongsView(generics.ListAPIView):
    """
    Provides a get method handler.
    """
    queryset = Songs.objects.all()
    serializer_class = SongsSerializer

音乐/serializers.py

from rest_framework import serializers
from .models import Songs


class SongsSerializer(serializers.ModelSerializer):
    class Meta:
        model = Songs
        fields = ("title", "artist")

models.py

from django.db import models

class Songs(models.Model):
    # song title
    title = models.CharField(max_length=255, null=False)
    # name of artist or group/band
    artist = models.CharField(max_length=255, null=False)

    def __str__(self):
        return "{} - {}".format(self.title, self.artist)

【解决方案1】：

class ListSongsView(generics.ListCreateAPIView):
    """
    Provides a get method handler.
    """
    queryset = Songs.objects.all()
    serializer_class = SongsSerializer

你需要ListCreateAPIView，因为ListView只有GET方法并且不允许POST方法

美好的一天

generics.ListAPIView 不允许 POST，它只能是 GET。如果你想允许 GET 和 POST。您可以使用 generics.ListCreateAPIView 继承人 documentation

在你的音乐/views.py 上

from rest_framework import generics
from .models import Songs
from .serializers import SongsSerializer


class ListSongsView(generics.ListCreateAPIView):
    """
    Provides a get method handler.
    """
    queryset = Songs.objects.all()
    serializer_class = SongsSerializer
