如果出现这样的提示，说明IP已经被拉黑了。
那么即使不是恶意的访问（几秒一次不算吧），也得上代理。
//创建无Chrome无头参数
ChromeOptions options=new ChromeOptions();
//chromeOptions.addArguments("-headless");
String proxyServer = "93.170.6.26:8080";
// proxy
Proxy proxy = new Proxy().setHttpProxy(proxyServer).setSslProxy(proxyServer);
options.setProxy(proxy);
WebDriver wd = new ChromeDriver(options);
好了，又可以愉快的访问了。
如果要对Chrome设置参数，比如下载路径。或者不下载图片。可以自定义参数
我自己的百度的感受就是，基本上搜索结果里面Python的占了主流。Java不是做爬虫的好方式。
还有个问题，如果发现代理IP失效了，怎么动态替换呢？
