style="color: black;">没法</span>对接公安<span style="color: black;">分部</span>的身份认证系统的。</span><span style="color: black;">几乎都是在网上买<span style="color: black;">有些</span>大的互联网<span style="color:

style="color: black;">因此</span>为了减少<span style="color: black;">机构</span>的开支,<span style="color: black;">咱们</span>在拿到用户提交的身份证信息去认证前应该自己先检验一下身份证的格式,<span style="color: black;">倘若</span>连最基本的身份证格式就不满足的话,<span style="color: black;">咱们</span>完全<span style="color: black;">能够</span>直接驳回,不必走接下来的花钱认证流程了,<span style="color: black;">况且</span><span style="color: black;">亦</span><span style="color: black;">能够</span><span style="color: black;">创立</span>一个用户身份证表,把每次认证<span style="color: black;">经过</span>的数据存起来,以后每次都先从自己系统里的用户身份证表<span style="color: black;">查找</span>,查不到再去走认证流程,最大化节省<span style="color: black;">机构</span>开支。</span><span style="color: black;"><span style="color: black;">这儿</span><span style="color:
