推荐答案

要从上传控件中检索文件，您可以使用这段代码(它的 java 所以您需要将其转换为 ssjs ..)

To retrieve a file from an upload control you can use this piece of code ( its java so you need to convert it to ssjs..)

// get file from httpservletrequest 

HttpServletRequest hsr = (HttpServletRequest) FacesContext      .getCurrentInstance().getExternalContext().getRequest();
fileUploadID = 'XspFileUpload control'.getClientId(FacesContext.getCurrentInstance());
Map<?, ?> map = hsr.getParameterMap();
UploadedFile f = ((UploadedFile) map.get(fileUploadID));

if (f == null) {
  throw new java.lang.Exception("File could not be found");
}

String fileName = f.getServerFileName()
if (super.isValid() && !this.isHidden()) {
   File serverFile = f.getServerFile();
   if (serverFile != null && serverFile.exists()) {
       String dir = serverFile.getParent();
       File tempFile = new File(dir + File.separator + fileName); // create a handle to the file on server 
   }
}
