＆＃34;无法关注元素＆＃34;尝试使用selenium上传附件时出现异常

Question

尝试上传附件时，尝试发送密钥而不是打开基于操作系统的文件资源管理器窗口，因为发送文件的路径很容易。

尝试使用不同的元素标识符，仍然无法发送密钥。提到了下面的元素HTML。

附上元素的形象。

在Xpath下面试过，

Answer 1

如果您尝试上传文件，并且页面使用HTML提供的标准上传机制，则可以直接使用Selenium本身执行此操作。标准HTML机制带有<input type=‘file’>元素。在页面上找到文件上传元素后，您可以使用element.sendKeys(“full/path/and/file/name/here”);

其中元素为：

WebElement element = driver.findElement(By.cssSelector(input[type='file']));

Answer 2

我尝试使用不接受值的div路径。因此，将路径更改为输入值//*[@id='fileList']//*[@type='file']或//*[@id='fileList']//input[@type='file']。
