#3 建立java项目

package test;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Main {

	public static void main(String[] args) throws InterruptedException {
		System.setProperty("webdriver.chrome.driver",
				"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chromedriver.exe");
		WebDriver driver = new ChromeDriver();
		driver.get("http://www.baidu.com");
		System.out.println(driver.getTitle());
		Thread.sleep(100000);
		driver.quit();
	}

}

#4 运行效果

#5 使用

//赋值：
findElement.sendKeys("xxx");

#6 验证码处理

public void doPass(WebDriver driver, By moveBtn, int distance) throws InterruptedException {
		WebElement div = driver.findElement(moveBtn);

		Actions actions = new Actions(driver);
		actions.clickAndHold(div).perform();

		List list = WebDriverUtil.getTrack(distance);
		for (Long long1 : list) {
			actions.moveByOffset(long1.intValue(), 0).perform();
		}
		Thread.sleep(5);
		actions.release().perform();
	}

public static List getTrack(double distance) {

		List track = new ArrayList<>();
		double current = 0;
		double mid = distance * 3 / 4;
		double t = 0.2;
		double v = 0;
		int a = 0;
		while (current < distance) {
			if (current < mid) {
				a = 2;

			} else {
				a = -3;
			}
			double v0 = v;
			v = v0 + a * t;
			double move = v0 * t + 1 / 2 * a * t * t;
			current += move;
			track.add(Math.round(move));
		}
		return track;
