Question

我想在输入一些字符串进行搜索后从谷歌获取搜索结果。我怎么能用Selenium做到这一点？到目前为止，我设法创建了这个：

WebDriver driver = new ChromeDriver();
        driver.get("http://www.google.com/xhtml");
        Thread.sleep(5000);
        WebElement searchBox = driver.findElement(By.name("q"));
        searchBox.sendKeys("ChromeDriver");
        searchBox.submit();

        System.out.println("Current Url: " + driver.getCurrentUrl());

        List<WebElement> results = driver.findElements(By.xpath("//h3[@class=r]/a"));

        for(int i=0; i<results.size(); i++){
            System.out.println(">>>>> results " + results.get(i).getText());
        }

        // second attempt

        List<WebElement> allSearchResults = driver.findElements(By.cssSelector("ol li h3>a"));

        //iterate the above list to get all the search titles & links from that page
        for (WebElement eachResult : allSearchResults)
        {
            System.out.println("Title : " + eachResult.getText() + ", Link : " + eachResult.getAttribute("href"));
        }

我如何解决这个问题？

Answer 1

提交搜索表单后，您需要wait for the results to appear：

WebDriverWait wait = new WebDriverWait(webDriver, timeoutInSeconds);
wait.until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("h3.r a")));

Answer 2

你走在正确的轨道上。您的xpath似乎不正确。你错过了r

旁边的单引号

List<WebElement> results = driver.findElements(By.xpath("//h3[@class=r]/a"));

应该是

 List<WebElement> results = driver.findElements(By.xpath("//h3[@class='r']/a"));
