Jquery 将映像发送到服务器-错误415（不支持的媒体类型）："；不支持的媒体类型\“；图像/png\"；在请求中。”；

我正在尝试使用ajax将一个图像从前端发送到使用django rest框架的后端，但没有结果

响应错误是：

{“detail”：“请求中不支持的媒体类型\”image/png\”}

其中我尝试了很多不同的类型，而不是“image/png”。（我发送的img是png）

models.py

class Atom(models.Model):
    name = models.CharField(max_length=128,blank=True)
    bio = models.TextField()
    img = models.ImageField(null=True, blank=True, upload_to='users_app')
    user_account = models.ForeignKey(UserAccount,  on_delete=models.CASCADE, null=True, blank=True, related_name="atoms")

序列化程序.py

我还尝试了不同的解决方案来接受图像，但不确定错误是在这里，在模型中还是在ajax中

from drf_writable_nested import WritableNestedModelSerializer # Enable write nested
from .models import *
from drf_base64.fields import Base64ImageField

class AtomSerializer(serializers.HyperlinkedModelSerializer, WritableNestedModelSerializer):
    boonds = BoondSerializer(many=True,required=False)
    img = Base64ImageField(max_length=None, use_url=True, required=False)

    class Meta:
        model = Atom
        fields = ["name","bio", "img", "boonds"]

        partial = kwargs.pop('partial', False)
