Django查询数据库返回的查询序列（Qureysets）转成JSON问题

def showallinfo(request):
    articles = Article.objects.all()
    print(len(articles))
    print(type(articles))
    return HttpResponse(json.dumps(list(articles), default=lambda obj: obj.__dict__), content_type='application/json')

前端用ajax接受数据显示的时候用utf-8编码格式，可以解决编码问题了。
