Django图片完整路径设置

一、在settings中设置media

# settings.py
import os
from pathlib import Path
BASE_DIR = Path(__file__).resolve().parent.parent
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

二、在项目总的路由下添加图片路由

# urls.py
from django.urls import path, re_path
from django.conf.urls.static import serve
from 项目 import settings
urlpatterns = [
    re_path(r"^media/(?P<path>.*)$", serve, {'document_root': settings.MEDIA_ROOT})
]
# 注意： 必须加上$结尾

三、在创建序列化器

#serializers.py
from rest_framework import serializers
class ProductListSerializers(serializers.Serializer):
    """
    商品
    """
    ...
    products_front_image = serializers.ImageField(required=True, use_url=True)
    # 在序列化器中的ImageField字段添加上use_url=True，使用url

四、在views文件中调用序列化器

# views.py
from .models import Products
from rest_framework.views import APIView
from rest_framework.response import Response
class ProductsList(APIView):
    def get(self, request, *args, **kwargs):
        key_id = request.GET.get('id')
        print(key_id)
        products = Products.objects.filter(id=key_id)
        serializers = ProductListSerializers(products,
                                             many=True,
                                             context={"request": request})
        return Response(serializers.data)
# 在调用序列化器时传入参数context={"request": request}，如果想要图片加上url，必须传入该参数
'''请求结果'''
