问题：页面显示拒绝访问请求
定位：F12-》NetWork-》拒绝访问html（红色）-》Initiator
解决：Request initiator chain是一个依赖体系，如图就是访问第一个请求（白色链接）后跳转到第二个请求（灰色链接）。如果页面拒绝访问，就可以查看是最后一个请求哪里出了问题（比如路径）
金融小知识速记：
- No1 组织机构代码
全国组织机构代码由八位数字（或大写拉丁字母）本体代码和一位数字（或大写拉丁字母）校验码组成 ，如果有-则10位 - No2 统一社会信用代码
目前，营业执照、组织机构代码证、税务登记证已三合一，均用统一社会信用代码表示 - No3 我收集到的组织机构代码等生成器（更多代码，见github）
