【问题描述】：

我正在尝试在浏览器呈现之前查看实际的 html 内容。所以我在 node.js 中使用 selenium-webdriver。

这是我的代码和我得到的错误：

代码

var webdriver = require('selenium-webdriver'); 
var driver = new webdriver.Builder().
usingServer('http://localhost:4444/wd/hub').
withCapabilities(webdriver.Capabilities.chrome()).
build();
driver.get('http://www.example.com/example/abc');
driver.getPageSource().then(function(html) {
  console.log(html);
  return true;
});
driver.quit();

错误

【解决方案1】：

这意味着网络服务器没有运行。尝试在新的命令行窗口或选项卡中运行 webdriver-manager start --standalone
