Usage

From source file:org.apache.sling.engine.impl.parameters.ParameterSupport.java

private static final boolean isWWWFormEncodedContent(HttpServletRequest request) {
    String contentType = request.getContentType();
    if (contentType == null) {
        return false;
    }/*w  ww .j  a v  a2s  .  co  m*/

    // This check assumes the content type ends after the WWW_FORM_URL_ENC
    // or continues with blank or semicolon. It will probably break if
    // the content type is some string extension of WWW_FORM_URL_ENC
    // such as "application/x-www-form-urlencoded-bla"
    if (contentType.toLowerCase(Locale.ENGLISH).startsWith(WWW_FORM_URL_ENC)) {
        return true;
    }

/**
 * <p>// w w w  .  j av a  2s.co  m
 * Handle a multipart request.  The return value of this method will be <code>null</code>
 * if the following conditions are not satisfied:
 * <ol>
 * <li>request.getContentType() != null</li>
 * <li>content type is "multipart/form-data"</li>
 * <li>request method is "POST"</li>
 * </ol>
 * If these are satisfied, a Struts {@link MultipartRequestHandler} is created.  This object is used
 * to provide a mapping over both the regular {@link HttpServletRequest} parameters and the 
 * paramters that Struts creates to represent the file(s) that was uploaded.  If file(s) were 
 * uploaded, the {@link java.util.Map} returned has key / value pairs of these two structures:
 * <ul>
 * <li><code>String / String[]</code></li>
 * <li><code>String / {@link org.apache.commons.fileupload.FileItem}</code></li>
 * </ul>
 * <br/>
 * Invokers of this method should be aware that in this case, not all types returned from 
 * what looks like <code>request.getParameterValues(String key)</code> will be <code>String[]</code>.
 * </p>
 *
 * @param request the request object
 * @param bean the current action's associated {@link ActionForm}
 * @return <code>null</code> if the request is <i>not</i> multipart.  Otherwise, a {@link java.util.Map} 
 * is returned that contains the key / value pairs of the parameters in the request and the uploaded
 * files.
 * @throws ServletException if an error occurs loading this file.  These exception messages
 * are not internationalized as Struts does not internationalize them either.
