Selenium WebDriver Code

Selenium WebDriver 用于模拟浏览器的功能，可以做网站测试用，也可以用来做crawler。我是用eclipse开发的，导入selenium-server-standalone-***.jar（Right click project -->Properties --> Java Buid Path --> Libraries --> Add External Jar...）。这个包可以在Selenium官网下载。

下面的代码是简单的跟一个网站做交互：

public class IndeedJobSearch {

    public static void main(String[] args) throws InterruptedException {
        // TODO Auto-generated method stub

        //Create firefox driver to drive the browser
            //File pathBinary = new File("D:\\Programes\\tools\\FireFox\\firefox.exe");
            //FirefoxBinary Binary = new FirefoxBinary(pathBinary);
            //FirefoxProfile firefoxPro = new FirefoxProfile();
            //WebDriver driver = new FirefoxDriver(Binary, firefoxPro);
        //ChromeDriver or ie
        System.setProperty("webdriver.chrome.driver",//webdriver.ie.driver
                "D:\\Projects\\JavaWorkspace\\ThirdPartyLibs\\WebDriver\\chromedriver.exe");//IEDriverServer.exe
        WebDriver driver = new ChromeDriver(); //InternetExplorerDriver
        
        //Open Indeed home page
        driver.get("http://www.indeed.hk/");
        //Find what field and enter Selenium
        Thread.sleep(2000);
        driver.findElement(By.id("what")).sendKeys("Selenium");  //"findElements" will return all
        //Find location field and enter London
        driver.findElement(By.id("where")).clear();
        Thread.sleep(2000);
        driver.findElement(By.id("where")).sendKeys("Hong Kong");
        //Find FindJobs button and click on it
        Thread.sleep(2000);
        driver.findElement(By.id("fj")).click();
        //From job search results page, get page title and jobs count message
    
        System.out.println(driver.getTitle());
        System.out.println(driver.findElement(By.id("searchCount")).getText());
        
        driver.close();
    }

}

要抓数据就要用方法来定位数据，下面是普遍用到的数据定位方法：

public class LocatingStrategies {

    public static void main(String[] args) throws InterruptedException {
        // TODO Auto-generated method stub

        //Create firefox driver to drive the browser
            File pathBinary = new File("D:\\Programes\\tools\\FireFox\\firefox.exe");
            FirefoxBinary Binary = new FirefoxBinary(pathBinary);
            FirefoxProfile firefoxPro = new FirefoxProfile();
            WebDriver driver = new FirefoxDriver(Binary, firefoxPro);
                
        //Open Indeed home page
        driver.get("http://www.indeed.hk/");
        
        //Locating by ID
        //driver.findElement(By.id("what")).sendKeys("Selenium");  //"findElements" will return all
        
        //Locating by name
        //driver.findElement(By.name("q")).sendKeys("Selenium");
        
        //Locating by LinkText
        //driver.findElement(By.linkText("建立個人檔案")).click();
        
        //Locating by partialLinkText
        //driver.findElement(By.partialLinkText("招聘廣告")).click();
        
        //Locating by Xpath By.xpath("//input[@placeholder='email']")).sendKeys("User NAme");
//        System.out.println(
//
//                driver.findElement(By.xpath("//img[@title='Indeed 香港']"))
//                .getAttribute("src")
//                
//                );
        
        //Locating by CssSelector By.cssSelector("css=input.input_submit")).click();
        //driver.findElement(By.cssSelector("input.input_submit")).click();

        //Locating by Tagname
        System.out.println(

                driver.findElements(By.tagName("a")).size()
                
                );
        
        //Locating by ClassName
        System.out.println(

                driver.findElements(By.className("input_text")).size()
                
                );
        driver.findElement(By.className("input_text")).sendKeys("Selenium");
    }

}

 对javacript的popups： alert, prompt, confirm box的交互处理：

public class JavaScriptPopups {

    public static void main(String[] args) throws InterruptedException {
        System.setProperty("webdriver.chrome.driver",
                "D:\\Projects\\JavaWorkspace\\ThirdPartyLibs\\WebDriver\\chromedriver.exe");//IEDriverServer.exe
        WebDriver driver = new ChromeDriver();
        
        driver.get("http://test1.absofttrainings.com/javascript-alert-confirm-prompt-boxes/");
        System.out.println(

                driver.findElements(By.className("headerText")).size()
                
                );
        //Thread.sleep(6000);
        driver.findElement(By.xpath("//button[text()='Display Alert Box']")).click();
        
        Alert alert = driver.switchTo().alert();
        System.out.println(
                "Alert text: " + alert.getText()
                );
        Thread.sleep(2000);
        alert.accept();
        driver.switchTo().defaultContent();
        System.out.println(driver.findElement(By.id("confirm")).getText()
                );
        driver.findElement(By.id("prompt")).click();
        alert = driver.switchTo().alert();
        Thread.sleep(3000);
        alert.sendKeys("Bruce");
        Thread.sleep(3000);
        alert.accept();
        driver.switchTo().defaultContent();
        
    }
}
