[Wicket-user] [report a bug] The encoding of UploadForm

[叶卫国]

The UploadForm class doesn't consider the encoding of request...  Can anybody 
fix it???

this is the code snippet form Tapestry:


    public void decode(HttpServletRequest request)
    {
        Map partMap = new HashMap();

        request.setAttribute(PART_MAP_ATTRIBUTE_NAME, partMap);

        // The encoding that will be used to decode the string parameters
        // It should NOT be null at this point, but it may be 
        // if the older Servlet API 2.2 is used
        String encoding = request.getCharacterEncoding();

        // DiskFileUpload is not quite threadsafe, so we create a new instance
        // for each request.

        DiskFileUpload upload = new DiskFileUpload();

        List parts = null;

        try
        {
             if (encoding != null)
                upload.setHeaderEncoding(encoding);
            parts = upload.parseRequest(request, _thresholdSize, _maxSize, 
_repositoryPath);
        }
        catch (FileUploadException ex)
        {
            throw new ApplicationRuntimeException(
                Tapestry.format("DefaultMultipartDecoder.unable-to-decode", 
ex.getMessage()),
                ex);
        }

        int count = Tapestry.size(parts);

        for (int i = 0; i < count; i++)
        {
            FileItem uploadItem = (FileItem) parts.get(i);

            if (uploadItem.isFormField())
            {
                try
                {
                    String name = uploadItem.getFieldName();
                    String value;
                    if (encoding == null)
                        value = uploadItem.getString();
                    else
                        value = uploadItem.getString(encoding);
                        
                    ValuePart valuePart = (ValuePart) partMap.get(name);
                    if (valuePart != null)
                    {
                        valuePart.add(value);
                    }
                    else
                    {
                        valuePart = new ValuePart(value);
                        partMap.put(name, valuePart);
                    }
                }
                catch (UnsupportedEncodingException ex)
                {
                    throw new ApplicationRuntimeException(
                        Tapestry.format("illegal-encoding", encoding),
                        ex);
                }
            }
            else
            {
                UploadPart uploadPart = new UploadPart(uploadItem);

                partMap.put(uploadItem.getFieldName(), uploadPart);
            }
        }

    }
