無法使用Selenium網絡驅動器

Question

我想通過下面的代碼使用硒網絡驅動程序上傳文件上傳文件：

 WebDriver driver = new HtmlUnitDriver(); 

     // And now use this to visit login page 
     driver.get(URL_UPLOADFORM); 

     // Find the text input element by its name 
     WebElement userIDElement = driver.findElement(By.id("user_login")); 
     userIDElement.sendKeys(USER_ID); 

     WebElement passwordElement=driver.findElement(By.id("user_password")); 
     passwordElement.sendKeys(PASSWORD); 

     passwordElement.submit(); 
     // Enter something to search for 
     //element.sendKeys("Cheese!"); 

     // Now submit the form. WebDriver will find the form for us from the element and redirect to the form with file upload page 
     //element.submit(); 

     // Check the title of the page 
     System.out.println("Page title is: " + driver.getTitle()); 
     System.out.println(driver.getCurrentUrl()); 


     WebElement fileUpload=driver.findElement(By.id("gallery_item_photo")); 
     System.out.println(fileUpload.toString()); 
     fileUpload.sendKeys("C:\\Users\\abc\\Pictures\\fileimg.jpg"); 
     WebElement commitButton=driver.findElement(By.name("commit")); 
     System.out.println(commitButton.toString()); 
     commitButton.click(); 

     System.out.println(driver.getCurrentUrl()); 
     driver.quit(); 

該文件沒有得到上傳並輸出結果是：

Page title is: New Photo 
http://www.andromo.com/projects/276345/gallery_activities/24456/gallery_items/new 
<input id="gallery_item_photo" name="gallery_item[photo]" value="" type="file" /> 
<button class="big button" name="commit" type="submit" value="commit"> 
http://www.andromo.com/projects/276345/gallery_activities/24456/gallery_items 

這裏是表單元素的HTML中使用它，我要上傳的文件：

<form accept-charset="UTF-8" action="/projects/276345/gallery_activities/24456/gallery_items" class="formtastic gallery_item" enctype="multipart/form-data" id="new_gallery_item" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="A5lmLTkPubF7RXTrMN7+jNrHUsy0rsfHMW+Rpisjzug=" /></div> 

    <fieldset class="inputs"><ol> 

     <li class="string optional" id="gallery_item_title_input"><label for="gallery_item_title">Title</label><input id="gallery_item_title" maxlength="255" name="gallery_item[title]" type="text" /> 
<p class="inline-hints">What is this a photo of?</p></li> 

     <li class="string optional" id="gallery_item_description_input"><label for="gallery_item_description">Description</label><input id="gallery_item_description" name="gallery_item[description]" type="text" /> 
<p class="inline-hints">Enter a short description of this photo</p></li> 

     <li class="file optional" id="gallery_item_photo_input"><label for="gallery_item_photo">Upload Photo</label><input id="gallery_item_photo" name="gallery_item[photo]" type="file" /> 
<p class="inline-hints">Maximum 1024x1024, 2 MB, .JPG format</p></li> 

     <li class="numeric required" id="gallery_item_position_input"><label for="gallery_item_position">Position<abbr title="required">*</abbr></label><input id="gallery_item_position" name="gallery_item[position]" type="text" value="100" /> 
<p class="inline-hints">Lower numbers appear first in your gallery</p></li> 
</ol></fieldset> 
    <fieldset class="buttons"><ol> 
     <button class="big button" name="commit" type="submit" value="commit">Save Changes</button> 
     <a href="/projects/276345/gallery_activities/24456/edit" class="big button">Cancel</a> 
     <a href="http://support.andromo.com/kb/activities/photo-gallery-activity" class="big button" target="_blank">Help</a> 
</ol></fieldset> 
</form> 

現在有趣的事情如果我在上傳的文件中將上述表單填入真實瀏覽器並提交，它會將我帶到url：http://www.andromo.com/projects/276345/gallery_activities/24456/edit。但與硒，它帶我到http://www.andromo.com/projects/276345/gallery_activities/24456/gallery_items，一個在真正的瀏覽器（登錄後）的鏈接帶我到一個「抱歉這個頁面不存在」頁面。那麼這裏發生了什麼？我也嘗試過使用HtmlUnit（請參閱我今天發佈的問題this），但它給了我相同的結果。

你的代碼看起來對我來說是正確的。我假定該文件存在於您的系統上。你也提供了上傳文件的絕對路徑，這也是正確的。對我來說，它看起來像，表單沒有得到正確提交。因此，我建議使用submit();，而不是click();

WebElement commitButton=driver.findElement(By.name("commit")); 
commitButton.submit(); 

從您的評論，好像submit();作品FirefoxDriver()並沒有爲HtmlUnitDriver。我注意到您的HtmlUnitDriver沒有啓用Javascript。從文檔here，請嘗試以下

HtmlUnitDriver driver = new HtmlUnitDriver(); 
driver.setJavascriptEnabled(true); 

或

HtmlUnitDriver driver = new HtmlUnitDriver(true); 

另外，還要確保您有最新的硒庫。
