Question

所以下面的代码曾经工作但现在我运行了它总是给我这个例外。该代码主要用于在youtube的搜索栏中输入，然后单击搜索按钮。

代码：

WebDriver driver = new HtmlUnitDriver();
driver.get("https://www.youtube.com");
driver.findElement(By.name("search_query")).sendKeys("Selenium WebDriver"+Keys.ENTER);
driver.findElement(By.id("search-btn")).click();
List<WebElement> links = driver.findElements(By.tagName("a"));
for (int i = 0; i < links.size(); i++) {
    // print the link text
    System.out.println(links.get(i).getAttribute("title"));
    // Print the href's
    System.out.println(links.get(i).getAttribute("href"));
}

栏的html是：

< input id="masthead-search-term" autocomplete="off" autofocus="" onkeydown="if (!this.value &amp;&amp; (event.keyCode == 40 || event.keyCode == 32 || event.keyCode == 34)) {this.onkeydown = null; this.blur();}" class="search-term masthead-search-renderer-input yt-uix-form-input-bidi" name="search_query" value="" type="text" tabindex="1" placeholder="" title="Search" dir="ltr" spellcheck="false" style="outline: none;">

搜索按钮的html为：

<button class="yt-uix-button yt-uix-button-size-default yt-uix-button-default search-btn-component search-button" type="submit" onclick="if (document.getElementById('masthead-search-term').value == '') return false; document.getElementById('masthead-search').submit(); return false;;return true;" id="search-btn" tabindex="2" dir="ltr"><span class="yt-uix-button-content">Search</span></button>

我尝试使用javascript打开和关闭，但给了我同样的例外。我尝试使用xpath，但给了我同样的例外。

异常追踪：

第39行是提供的示例中的第3行。对不起，如果有任何遗漏或误导。这是第一次使用stackoverflow。我很高兴得到任何答案。

无法使用Keys.ENTER。这是更正后的代码 - ：

WebDriver driver = new HtmlUnitDriver();
driver.findElement(By.name("search_query")).sendKeys("Selenium WebDriver");
driver.findElement(By.id("search-btn")).click();
List<WebElement> links = driver.findElements(By.tagName("a"));
for (int i = 0; i < links.size(); i++) {
 // print the link text
System.out.println(links.get(i).getAttribute("title"));
// Print the href's
System.out.println(links.get(i).getAttribute("href"));
}
