我在尝试在Liferay 6.0 portlet中设置会话cookie时遇到问题.我希望能够将cookie设置到客户端浏览器以存储用于linkedin身份验证的应用程序密钥,然后可以由其他portlet检索它.
我可以使用以下内容读取cookie：
public void addLinkedInCV(ActionRequest request,ActionResponse response)
throws PortalException,SystemException {
HttpServletRequest convertReq = PortalUtil.getHttpServletRequest(request);
Cookie[] cookies = convertReq.getCookies();
...
}
这是我尝试阅读一个失败的尝试.
@Override
public void doView(RenderRequest renderRequest,RenderResponse renderResponse) throws IOException,PortletException {
HttpServletResponse convertRes = PortalUtil.getHttpServletResponse(renderResponse);
HttpServletResponse originalRes = (HttpServletResponse) ((HttpServletResponseWrapper) convertRes).getResponse();
Cookie linkedInCookie = new Cookie("linkedIn",util.getAppKey());
originalRes.addCookie(linkedInCookie);
}
解决方法
在没有大量修改Liferay门户本身的情况下,我发现设置portlet cookie的唯一方法是让portlet生成一个javascript,然后让客户端设置cookie.
if (renderRequest.getPortletSession(true).getAttribute("set_cookie")!=null){
return;
}
String cookie_value = renderRequest.getPortletSession(true).getId();
String cookie_hours = "6";
StringBuffer buf = new StringBuffer();
buf.append("\n <script>");
buf.append("\n var today = new Date();");
buf.append("\n var expires_date = new Date ( today.getTime() + (" + cookie_hours + "*1000*60*60) );");
buf.append("\n document.cookie = \"linkedIn=" + util.getAppKey() + ";expires=\"+expires_date.toGMTString();");
buf.append("\n </script>");
renderResponse.setContentType("text/html");
PrintWriter out = renderResponse.getWriter();
out.println(buf.toString());
renderRequest.getPortletSession(true).setAttribute(SET_COOKIE,cookie_value);
虽然不是最佳的,但仍然是一种有效的解决方案;)
