無法在twitter中輸入ID

Question

我正在運行下面的硒代碼。

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"); 
    } 
} 

但是我得到了下面的錯誤。

log4j:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAddCookies). 
log4j:WARN Please initialize the log4j system properly. 
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

請讓我知道我該如何解決它。

我試着用JavascriptExecutor如下，它的工作！它填充user name和password，如foo和bar和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(); } 
} 

Answer 2

我遇到的問題是，當我瀏覽到自己的網站，登錄面板中顯示，但是當我做了代碼同樣的事情，登錄面板不顯示。解決方法是單擊「登錄」按鈕，然後輸入用戶名/密碼。下面的代碼點擊登錄按鈕並輸入電子郵件地址和密碼

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");

編輯：對於那些誰也看不出登錄按鈕???這是我看到的。
