說明：使用django模型類ImageFields字段上傳圖片到服務(wù)器本地，并使用postman測試

• models.py的內(nèi)容

class People(BaseModel):
  
    name = models.CharField(verbose_name='姓名', max_length=1024, default="",blank=True, null=True)
    age = models.CharField(verbose_name='年齡',max_length=30,blank=True, null=True,help_text='年齡')
    face = models.ImageField(upload_to='pic')
    create_time = models.CharField(max_length=30,verbose_name='時間', blank=True, null=True)

    class Meta:
        db_table = 'people'
        verbose_name = '人物信息'
        verbose_name_plural = verbose_name

• serializer.py的內(nèi)容

class PeopleSerializer(serializers.ModelSerializer):
    face = serializers.ImageField(max_length=None, use_url=True)

    class Meta:
        model = People
        fields = ("__all__")

• views.py的內(nèi)容

class PeopleViewSet(ModelViewSet):

    lookup_field = 'pk'
    serializer_class = PeopleSerializer

urls.py

router = DefaultRouter()
router.register('adddata', views.PeopleViewSet,basename='people')

• 發(fā)送請求，報錯信息如下：

The number of GET/POST parameters exceeded settings.DATA_UPLOAD_MAX_NUMBER_FIELDS錯誤

DATA_UPLOAD_MAX_NUMBER_FIELDS = 10240

• 再次運(yùn)行，成功
