第一次发现这种情况，驱动版本完全对的上，但是调用 chrome 就提示 Only local connections are allowed. 然后浏览器调用失败报错。
Only local connections are allowed. Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver s afe. ChromeDriver was started successfully.
解决方法：
调用 chrome 驱动的时候加个参数 --whitelisted-ips=""，值为空就是把所有调入来源都加入白名单。
ips 的全称是 intrusion prevention system，解释为入侵防御系统。
C:\Selenium2.0\driver>chromedriver_70.0.3538.97_win32.exe --whitelisted-ips="" Starting ChromeDriver 70.0.3538.97 (d035916fe243477005bc95fe2a5778b8f20b6ae1) on port 9515 All remote connections are allowed. Use a whitelist instead!
如果是封装好的不能代码里集成，可以外部 cmd 窗口里启用驱动，后面加上这个参数，注意参数前要有个空格，注意窗口不要关，不然就失效了，可以保证启用过程中可以正常的调用 chrome。
如果每次都这么做，可以创建个快捷方式，里面写好参数，这样就每次执行个快捷方式就完事了。
详细报错内容展示：
老版本和新版本的报错内容存在一定差异。
