Java 和 Selenium 显示 Google 搜索结果的最佳方式

Question

我对 Selenium 和 Java 非常陌生，但我正在尝试制作一个简单的程序来加载 google，进行搜索，然后显示有多少结果以及加载 google 搜索所需的时间。我遇到了结果问题，并显示它

import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;

public class GoogleSearch {

public static void main(String[] args) {

    FirefoxDriver driver = new FirefoxDriver();
    driver.get("http://google.com");


    WebElement searchTextBox = driver.findElement(By.id("lst-ib"));
    searchTextBox.sendKeys("Colin");

    String pageUrl = driver.getCurrentUrl();
    System.out.println(pageUrl);

    WebElement searchButton = driver.findElement(By.className("lsb"));
    searchButton.click();

    String pageTitle = driver.getTitle();
    System.out.println("Page title is:" + pageTitle);


    WebDriverWait wait = new WebDriverWait(driver, 5);// 5 seconds 
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("resultsStats")));
    driver.findElement(By.id("resultsStats"));

    WebElement results = driver.findElement(By.id("resultsStats")); //displays # of results from search
        System.out.println(results);

    //driver.quit();


}
}

以下是我得到的结果:

https://www.google.com/?gws_rd=ssl
Page title is:Google
Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"id","selector":"resultsStats"}
Command duration or timeout: 13 milliseconds

Answer 1

这不是resultsStats，而是resultStats。进行相同的更改，然后就可以开始了!

wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("resultStats")));
driver.findElement(By.id("resultStats"));

WebElement results = driver.findElement(By.id("resultStats")); //displays # of results from search
