从 HTML 发送多个文件 从 Java 输入
Sending multiple files from HTML Input from Java
使用 HtmlUnit 和 Java 我正在尝试通过此元素发送一些文件：
<input type="file" multiple="multiple" class="dz-hidden-input" accept="image/jpeg, image/gif ,image/png" style="visibility: hidden; position: absolute; top: 0px; left: 0px; height: 0px; width: 0px;">
它来自 Dropzone javascript 库，它创建了这个隐藏的 HTML 元素以管理文件上传。
我试过（除其他外）这个：
File fileToUpload = new File("C:\image.jpg");
HtmlFileInput fileUploader = (HtmlFileInput) currentPage.getFirstByXPath("//input[@type='file']");
fileUploader.setFiles(fileToUpload);
但它因这个异常而悲惨地失败了，这让我确定这不是继续进行的方式，有什么提示吗？
