chrome+selenium自动化编程

安装chromedriver

 下载

chromedriver的版本一定要与Chrome的版本一致，不然就不起作用。

有两个下载地址：

1、http://chromedriver.storage.googleapis.com/index.html

2、ChromeDriver Mirror

 Java代码 展示了基本的操作

element.getAttribute("outerHTML")   //获取Html值

element.getAttribute("outerHTML");//获取html
html = driver.execute_script("return document.documentElement.outerHTML")
html = driver.find_element_by_xpath("//*").get_attribute("outerHTML")
# 不要用 driver.page_source，那样得到的页面源码不标准

获取元素的所有属性
Object[] attr = ((JavascriptExecutor)seleniumdriver).executeScript("return arguments[0].attributes);", webElement);


String source=driver.findElement(By.xpath("/html/body/script[6]")).getAttribute("innerHTML");
