        出错
        publish_list = Publisher.objects.all()
        return HttpResponse(json.dumps(publish_list))#无法打印，返回值是一个querset对象
        #c出错
        publish_list = list(Publisher.objects.all())
        return HttpResponse(json.dumps(publish_list))  # 无法打印，返回值是一个querset对象
        第一种打印全部
        publish_list = list(Publisher.objects.all().values())
        return HttpResponse(json.dumps(publish_list))
        第二种打印指定的name和email
        publish_list = list(Publisher.objects.all().values("name","email"))
        return HttpResponse(json.dumps(publish_list))
        第三种
        publish_list = Publisher.objects.all()
        temp = []
        for publish in publish_list:
            temp.append({
                "name":publish.name,
                "email":publish.email}
            )
            return HttpResponse(json.dumps(temp))
        第四种
        from django.forms.models import model_to_dict
        publish_list = Publisher.objects.all()
        temp = []
        for publish in publish_list:
            temp.append(model_to_dict(publish))
            return HttpResponse(json.dumps(temp))
        第五种
        from django.core import serializers
