推荐答案

HTML5约束验证消息是

注意:HTML5约束验证不会消除服务器端验证的需要.即使可以预期的无效表单请求的数量要少得多，无效请求仍然可以由不兼容的浏览器(例如，没有HTML5和JavaScript的浏览器)或试图欺骗您的Web应用程序的坏人发送.因此，与HTML4一样，您还需要在服务器端验证输入约束，方法与在客户端进行的验证一致.

Note: HTML5 Constraint validation doesn't remove the need for validation on the server side. Even though far fewer invalid form requests are to be expected, invalid ones can still be sent by non-compliant browsers (for instance, browsers without HTML5 and without JavaScript) or by bad guys trying to trick your web application. Therefore, like with HTML4, you need to also validate input constraints on the server side, in a way that is consistent with what is done on the client side.

解决方案

要检索从element.setCustomValidity()方法得到的文本，可以使用以下解决方案:

Solution

To retrieve the text which results out from the element.setCustomValidity() method, you can use the following solution:

• 代码块:

• Code Block:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class validationmessage {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
        ChromeOptions options = new ChromeOptions();
        options.addArguments("start-maximized");
        options.addArguments("disable-infobars");
        options.addArguments("--disable-extensions"); 
        WebDriver driver =  new ChromeDriver(options);
        driver.get("http://132.148.19.159:8086/panel/#/login");
        WebElement username = new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input.form-control.ng-pristine.ng-invalid.ng-invalid-required.ng-touched[placeholder='Usuario']")));
        System.out.println(username.getAttribute("validationMessage"));
    }
}

控制台输出:
