django调试时遇到‘签名已过期’

调试时遇到发送请求，刷新页面都是这个响应{"detail":"Signature has expired."}

代码视图：

class MessageView(CreateAPIView, ListAPIView, DestroyAPIView):
    queryset = UserLeavingMessage.objects.all()
    serializer_class = LeavingSerializer
    permission_classes = [IsAuthenticated]

    def get_object(self):
        return self.request.user
代码模型类：
class MessageModel(models.Model):
    message_choice= (
        (1, '留言'),
        (2, '投诉'),
        (3, '询问'),
        (4, '售后'),
        (5, '求购'),
    )
    user = models.ForeignKey(UserProfile,on_delete=models.CASCADE,verbose_name='用户')
    file = models.FileField(verbose_name='上传文件',help_text='上传文件',upload_to='message/image/',null=True)
    subject = models.CharField(verbose_name='主题',max_length=32,default='')
    message = models.CharField(verbose_name='留言内容',max_length=1024,default='')
    message_type = models.IntegerField(verbose_name='留言类型',choices=message_choice,default=1,help_text=u'留言类型: 'u'1(留言),'u'2  (投诉),'u'3(询问),'u'4(售后),'u'5(求购)')
    add_time = models.DateTimeField(auto_now=True,auto_created=True,verbose_name='添加时间')

    class Meta:
        db_table = 'db_user_message'
        verbose_name = '用户留言'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.subject
代码序列化器：
class MessageSerializer(serializers.Serializer):
    id  = serializers.IntegerField(label='用户留言id',read_only=True)
    user = serializers.HiddenField(default=
                                   serializers.CurrentUserDefault())
    message = serializers.CharField(label='用户留言',max_length=1024)
    message_type = serializers.IntegerField(label='留言类型')
    fie = serializers.FileField(label='上传文件',allow_empty_file=True,allow_null=True)
    subject = serializers.CharField(label='主题',max_length=32)
    add_time = serializers.TimeField(read_only=True,format="%Y-%m-%d %H:%M")

    def create(self, validated_data):
        print(validated_data)
        res = MessageModel.objects.create(**validated_data)
        return  validated_data
