selenium 上传文件 java ChromeDriver/FirefoxDriver

Question

我正在尝试自动执行上传图片的测试。我可以在“标题”框中添加文本，但是当我输入文件的位置时，我可以成功输入文本，但是网站告诉我我没有上传有效的 .jpg 文件。当我手动进行测试时，我无法输入文本，但我可以浏览文件并成功上传。这是我的代码：

 driver.findElement(By.xpath("//input[@id='FakeInputName2']")).sendKeys("C:\\Users\\MyUsername\\Pictures\\Lighthouse.jpg");

HTML 代码如下所示：

<tr>
<td align="right"> Image: </td>
<td>
    <div id="RenamedUpload1" class="RenameUpload RenameUpload RenameUpload_Office2007">
        <ul id="RenameUpload1ListContainer" class="renamedInputs">
            <li id="RenameUpload1row0">
                <span class="blerghFileWrap blerghStyled">
                    <input id="FakeInputName" class="renamedThisFakeInput somethingNoDecorate" type="text" tabindex="-1" size="67">
                    <label for="FakeInputName" style="display:none">label</label>
                    <input class="notButton notBrowse" type="button" tabindex="-1" value="Select" style="border: 0px dotted;">
                    <input id="FakeInputName2" class="notFileInput" type="file" tabindex="0" name="FakeInputName2" size="68">
                    <label for="FakeInputName2" style="display:none">label</label>
                </span>
            </li>
        </ul>
    </div>
</td>

我还尝试了类似问题的其他答案所建议的 Runtime.getRuntime() 方法。那根本行不通。有人可以帮忙吗？

这是控制台输出和堆栈跟踪（澄清一下（MyClass 第 114 行是 String filePath = url.getFile(); 所在的行）：

Answer 1

“*.jpeg”-文件不是有效的 .jpg 文件。

你能至少显示文件上传的 html-Code 吗？

您确定您的 JVM 可以访问该文件吗？也许您应该将该文件添加到您的资源文件夹中。如果您的文件存储在“[...]\workspace\projcetname\src\test\resources”这应该可以工作：

String pathToUpload = "/Lighthouse.jpg";
URL url = MYCLASSNAME.class.getResource(pathToUpload);
String filePath = url.getFile();
System.out.print(filePath);
File imgToUpload = new File(filePath);
String absolutePath = imgToUpload.getAbsolutePath();
System.out.print(absolutePath);
driver.findElement(By.xpath("//input[@id='FakeInputName2']")).sendKeys(absolutePath);
System.out.print(driver.getPageSource());

注意：'Myclass' 必须替换为您当前的类名。
