Django REST框架API:如何用用户指定的名称保存/上传图像(例如:username.jpg)在Django服务

Question

我想通过rest API在Django服务器上上传名称(由用户给出)的图像，但我无法找到解决方案。请告诉我如何上传给定名称的图像。下面是我的代码(主要):

IN API TASK ->URLS:

from django.conf.urls import include, url
from django.contrib import admin
from rest_framework import routers
from django.conf import settings
from myapi import views
from django.conf.urls.static import static
#Define API Routes
router = routers.DefaultRouter()
router.register(r'myimage', views.myimageViewSet)  #we have only on viewset

urlpatterns = [
url(r'^',include(router.urls)),
url(r'^admin/',admin.site.urls),
]+static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

在我的API

1。模型

from django.db import models
# Create your models here.
class myimage(models.Model):
my_name=models.CharField(max_length=50)
my_image=models.ImageField(upload_to='Images/',default='Images/None/No-img.jpg')
def __str__(self):
return self.my_name

2。序列化器

from rest_framework import serializers
from .models import myimage
class myimageserializer(serializers.ModelSerializer):
class Meta:
model =myimage
fields=('id','my_name','my_image')

3。

from django.shortcuts import render
from .models import myimage
from rest_framework import viewsets
from .serializers import myimageserializer
from rest_framework import filters
import django_filters.rest_framework
class myimageViewSet(viewsets.ModelViewSet):
queryset = myimage.objects.all()  #We use Filters for Ordering so remove order_by part
serializer_class = myimageserializer
filter_backends = (django_filters.rest_framework.DjangoFilterBackend,filters.OrderingFilter,)
ordering  = ('id','my_name',)

4。管理

from django.contrib import admin
from .models import myimage
admin.site.register(myimage)

Answer 1

您需要使用FileParser才能在请求数据对象中获取图像细节。我建议您遵循DRF的FileParser示例

中的示例

Answer 2

我改变了我的代码如下所述，现在它为我工作，如果你有任何更好的解决方案，请在这里建议#happycoding

1。views.py

from django.shortcuts import render
from .models import myimage
from rest_framework import views
from .serializers import myimageserializer
import django_filters.rest_framework
from rest_framework.views import APIView
from rest_framework.response import Response
from rest_framework import status
class myimageView(APIView):

def get(self, request):
myimagelocal= myimage.objects.all()
serializer = myimageserializer(myimagelocal, many=True)
return Response(serializer.data)

def post(self, request):
myname=request.data['my_image'].name
myformat=""
for c in reversed(myname):
myformat+=c
if c=='.' :
break
myformat=myformat[: : -1]
request.FILES['my_image'].name=request.data['my_name']+myformat

serializer = myimageserializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

在API_TASK→url:

from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls,name='admin'),
path('',include('myapi.urls'))
]+static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

在API_Task→myapi→url

from django.urls import path
from .views import myimagedetailsView, myimageView
urlpatterns = [
path('myimage/', myimageView.as_view(),name='myimageView'),
]

其余文件不变
