无法获得所有总页面的链接

Question

我试图在谷歌中键入selenium，并在记事本文件中获取结果的所有标题文本。我想得到所有页面上的所有可用链接，直到搜索的最后一页。但只有第一页的链接，我得到。当我调试并运行时，它可以工作大约10页。帮我做这件事。

JAVA代码：

public class weblink 
{
    public static void main(String[] args) throws IOException, InterruptedException {
    WebDriver driver;
    System.setProperty("webdriver.chrome.driver", "E:\\disha.shah/myWork/eclipse/chromedriver.exe");
    driver = new ChromeDriver();
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.get("http://www.google.co.in/");
    driver.findElement(By.id("lst-ib")).sendKeys("Selenium");
    driver.findElement(By.id("_fZl")).click();

    PrintStream ps = new PrintStream(new File(("E:\\disha1.txt")));
    do
     {
        List<WebElement> findElements = driver.findElements(By.xpath("//*[@id='rso']//h3/a"));  
        for (WebElement webElement : findElements)      
        {
            System.out.println("-" + webElement.getText()); // for title
          //System.out.println(webElement.getAttribute("href")); // for links
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
            System.setOut(ps); 
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        }   

        Thread.sleep(1000);


        if(driver.findElement(By.linkText("Next")).isDisplayed()== true)
        { 
            driver.findElement(By.linkText("Next")).click();     
        }
        else
        {   
            System.out.println("All Link is Covered");
        }


    }
    while(driver.findElement(By.linkText("Next")).isDisplayed() );
    {
        //Thread.sleep(2000);
    }


    }
 }

我做了一些更正。更新的代码在下面。-

public static void main(String[] args) throws IOException, InterruptedException 
{
    WebDriver driver;
    System.setProperty("webdriver.chrome.driver", "D:/Application/chromedriver.exe");
    driver = new ChromeDriver();
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    driver.get("http://www.google.co.in/");

    driver.findElement(By.id("lst-ib")).sendKeys("Selenium");
    driver.findElement(By.id("_fZl")).click();
    Boolean nextButtonFlag = true;
    // Create two separate file storing the result
    PrintStream searchTitle = new PrintStream(new File(("D:\\Titles.txt")));
    PrintStream searchLink = new PrintStream(new File(("D:\\Links.txt")));
    do
     {
               List<WebElement> findElements = driver.findElements(By.xpath("//h3[@class='r']/a"));  
               for (WebElement element : findElements)
               {
                   // Write all received links and title inn txt file
                   searchTitle.append(element.getText()+"\n");
                   searchLink.append(element.getAttribute("href")+"\n");
               }   
                    Thread.sleep(2000);
               try
               {
                   driver.findElement(By.linkText("Next")).click();
                }
               catch(Exception e)
               {
                   //  no more next button to navigate further link
                   nextButtonFlag=false;
               }

               Thread.sleep(2500);
        }
        while(nextButtonFlag);

          System.out.println("Execution done");
          searchTitle.close();
          searchLink.close();
    }
 }
