如何使用Selenium和Java在ProtonMail注册页面的用户名字段中点击。

Question

我无法在用户名中使其成为莱特，在。https:/mail.protonmail.comcreatenew?语言=en。. 不知为什么，它找不到或不能点击 "选择用户名"，有人能帮我吗？

代码审判；

public class LaunchApplication {
    public static void main(String[] args) throws InterruptedException {

        System.setProperty("webdriver.chrome.driver", "C:\\chromedriver_win32\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.manage().window().maximize();
        int number = 1;


        String url = "https://protonmail.com";
        String password = "passwordpassword123123";
        String username = "";
        String characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
        Random rand = new Random();
        int length = 8;





       while (number > 0){

           //Create an random string for the user name:
           // video of how to make string randomicer https://www.youtube.com/watch?v=CZYeTblcOU8 check it out
           char[] text = new char[length];
           for(int i = 0; i < length; i++){
               text[i] = characters.charAt(rand.nextInt(characters.length()));
           }

           for(int i = 0; i < text.length; i++){
               username += text[i];
           }
           System.out.println(username);
           Thread.sleep(2000);

           //Program starting: video to make it all work https://www.youtube.com/watch?v=QY0iQpX0LDU
           driver.get(url);
           System.out.println(driver.getTitle());
           Thread.sleep(2000);

           driver.findElement(By.linkText("SIGN UP")).click();
           Thread.sleep(5000);

           driver.findElement(By.className("panel-heading")).click();
           Thread.sleep(2000);

           driver.findElement(By.id("freePlan")).click();
           Thread.sleep(5000);
           System.out.println("Here");
           Thread.sleep(5000);
           System.out.println("pass1");


           driver.findElement(By.name("password")).sendKeys(password);
           System.out.println("pass2");
           driver.findElement(By.name("passwordc")).sendKeys(password);
           Thread.sleep(2000);
           System.out.println("Username here");


           try{
               driver.findElement(By.id("username")).click();
           }catch (Exception E){
               System.out.println("DOnt work1");
           }
           try{

           }catch (Exception B){
               System.out.println("DOnt work2");
           }
           try{
               driver.findElement(By.id("input")).click();
           }catch (Exception A){
               System.out.println("DOnt work3");
           }
           try{
               driver.findElement(By.linkText("Choose")).click();
           }catch (Exception A){
               System.out.println("DOnt work4");
           }
           try{
               driver.findElement(By.xpath("//input[@id='#username.input']")).click();
           }catch (Exception A){
               System.out.println("DOnt work5");
           }
           try{
               driver.findElement(By.tagName("messages=\"[object Object]\"")).click();
           }catch (Exception A){
               System.out.println("DOnt work6");
           }



           number = number-1;
        }





    }

至 click() 的元素中，占位符为 选择用户名 网址内 https:/mail.protonmail.comcreatenew?语言=en。，因为所需元素在 <iframe> 所以你必须。

• 诱导 WebDriverWait 为所欲为 FrameToAvailableAndSwitchToIt..
• 诱导 WebDriverWait 为所欲为 elementToBeClickable.

• 您可以使用以下任一方式 定位策略:

  • 使用 cssSelector:

    driver.get("https://mail.protonmail.com/create/new?language=en");
    new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector("div.usernameWrap iframe[title='Registration form']")));
    new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.input#username"))).click();
    

  • 使用 xpath:

    driver.get("https://mail.protonmail.com/create/new?language=en");
    new WebDriverWait(driver, 10).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.xpath("//div[@class='usernameWrap']//iframe[@title='Registration form']")));
    new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//input[@class='input' and @id='username']"))).click();
    

• 浏览器快照。
