    onum = bsj.find("original")
    if onum != None:
        num = onum.get_text()[:3]
        if num == '210':
            print("%s可以注册" % domain)

        else:
            print(html.text)
            print("出现未知问题")
        return num
    else:
        print("让我哭一会，ip可能被封了")
        return None
