无法在Twitter中输入ID

Question

我正在运行以下硒代码。

import org.openqa.selenium.By;
import org.openqa.selenium.firefox.FirefoxDriver;

public class twitter {

    public static void main(String[] args) throws InterruptedException {
        FirefoxDriver fd = new FirefoxDriver();
        fd.get("https://twitter.com/?lang=en");
        Thread.sleep(2000L);
        fd.findElement(By.xpath(".//*[@id='signin-email']")).sendKeys("Hello");
    }
}

但我收到以下错误。

log4j:WARN Please initialize the log4j system properly.

请让我知道如何解决它。

Answer 1

我遇到的问题是当我自己导航到网站时，登录面板显示但是当我使用代码做同样的事情时，登录面板没有显示。解决这个问题的方法是点击＆＃34;登录＆＃34;按钮，然后输入用户名/密码。下面的代码单击“登录”按钮并输入电子邮件和密码

driver.get("https://twitter.com/?lang=en");
driver.findElement(By.cssSelector("button.StreamsLogin")).click();
driver.findElement(By.id("signin-email")).sendKeys("email");
driver.findElement(By.id("signin-password")).sendKeys("password");

编辑：对于那些看不到登录按钮的人???这就是我所看到的。

Answer 2

我尝试使用JavascriptExecutor，如下所示，它有效！它将user name和password填充为foo和bar以及submits。

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

public class TwitterTest {
    public static void main(String[] args) throws Exception {
        // The Firefox driver supports javascript 
        WebDriver driver = new FirefoxDriver();
       // driver.manage().window().maximize();

        // Go to the page
        driver.get("https://twitter.com/?lang=en");

        WebDriverWait wait = new WebDriverWait(driver,10);      
        WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@class='front-signin js-front-signin']")));
        JavascriptExecutor js = (JavascriptExecutor) driver;
        js.executeScript("document.getElementById('signin-email').value = 'foo';");
        js.executeScript("document.getElementById('signin-password').value = 'bar';");
        js.executeScript("document.getElementsByClassName('t1-form signin')[0].submit();");
        wait.wait(10);

        driver.quit();    }
}
