models.py

class photo(models.Model):
    class Meta:
        db_table = 'photo'
        verbose_name = '图片表'
    id = models.AutoField(primary_key=True)
    image = models.ImageField(upload_to='photos', default='avatar.jpg')
# manage.py 同级自动增加photos文件夹放置图片

url.py

from django.urls import path
urlpatterns = [
    # 上传图片
    path("upload_photo/", upload_photo_fun),
]

url.py

def upload_photo_fun(request):
    # 获取上传文件的处理对象
    try:
        pic = request.FILES.get('pic')
        print(pic)  # 输出图片名字
        type = request.POST.get("type", None)
        data = {"type":type, "image":pic}
        photo.objects.create(**data)
        obj = photo.objects.get(type=type)
        name = obj.image
        return JsonResponse({"code": 200, 'message': '新增成功',"name":str(name)})
    except Exception as e:
        return JsonResponse({"code": 500, 'error': str(e)})

调整nginx配置

http{
    client_max_body_size 300m
    # 设定通过nginx上传文件的大小
    # 表示客户端请求的最大可接受body大小
    # 它出现在请求头部的Content-Length字段
    # 如果请求大于指定的值，客户端将收到一个"Request Entity Too Large" (413)错误，通常在上传文件到服务器时会受到限制
