How to retrieve a user profile picture in Liferay

问题

I want to retrieve a user profile picture. How do i do it? Could you please share a code snippet? Im using Liferay 6.0.6. It has only user.getPortraitId() and no user.getPortraitURL(). So once i get the portrait id inside a JAVA class, what do i do with it?

回答1:

See the implementation of UserConstants.getPortraitURL(...) https://github.com/liferay/liferay-portal/blob/master/portal-service/src/com/liferay/portal/model/UserConstants.java

On this approach you can get the image url.

If you need the image object, you can load it with ImageLocalServiceUtil:

        long portraitId = user.getPortraitId();
        Image image = ImageLocalServiceUtil.getImage(portraitId);

回答2:

There are at least two options on rendering portraits in JSP:

<img src="<%= themeDisplay.getPathImage()%>  
  /image_gallery?img_id=<%= image.getImageId()%>&t=  
  <%= ImageServletTokenUtil.getToken(image.getImageId())%>">  

<img src="<%= themeDisplay.getPathImage() %>/user_portrait?img_id=<%=id %>">

The first approach contains additional security aspect based on security token which you may or may not find relevant to your needs.
