上传文件通过url传递参数

一般情况下通过表单post数据时，写在action后面的参数是没有效果的，但是如果是上传文件（multipart/form-data），这时还可以通过action传递参数，比如：

 

<form action="/as?s=bac" enctype="multipart/form-data" method="post" target="slFrame"><input type="hidden" name="b" value="bb" /></form>

同事写的解析字段但不解析文件的方法：

	private HashMap<String, String> parseFormData(HttpServletRequest request, HashMap<String, String> attrMap,
			ServletFileUpload upload) {
		FileItemIterator fii;
		try {
			fii = upload.getItemIterator(request);
			while (fii.hasNext()) {
				FileItemStream fis = fii.next();
				if (fis.isFormField()) {
					InputStream is = null;
					try {
						is = fis.openStream();
						int avx = is.available();
						byte[] b = new byte[avx];
						is.read(b);
						attrMap.put(fis.getFieldName(), new String(b));
					} catch (Exception e) {
						try {
							is.close();
						} catch (Exception ee) {
						}
					}
				}
			}
		} catch (FileUploadException e1) {
		} catch (IOException e1) {
		}
		return attrMap;
	}
