[opencms-dev] Access a file by uuid

[Yves Glodt]

On OpenCms 8 I had to adapt slightly to the new api, here the full code to
download a file by CmsUUID:

if (CmsUUID.isValidUUID(request.getParameter("id"))) {
    CmsUUID uuid = new CmsUUID(request.getParameter("id"));

    CmsObject cmso = OpenCms.initCmsObject("Guest");
    cmso.loginUser("user", "pass");

    CmsResource res = cmso.readResource(uuid);
    CmsFile file = cmso.readFile(res);

    response.setHeader("Content-Disposition", "attachment;
filename=\""+res.getName()+"\"");
    response.setContentType("application/octet-stream");
    response.setContentLength(file.getLength());
    OutputStream o = response.getOutputStream();
    o.write(file.getContents());
    o.flush();
    o.close();
}
