Sharepoint 2010 Rest api can not get RichTextField content

Question

I am using the Sharepoint 2010 rest api to get data of a custom content type item in "Pages" folder. The data is returned but I can not find the content of a custom RichTextField column. Is there any special setting or how should I do to get this content value ? Thanks

Here is the returned data from the browser:

Getting PublishingPageContent using REST doesn't seem to be possible especially in SP 2010 where you have limited options. You can use JSOM to do this:

function retrieveListItems() {

var clientContext = new SP.ClientContext(siteurl);
var oList = clientContext.get_web().get_lists().getByTitle('Pages');

var camlQuery = new SP.CamlQuery();
//camlQuery.set_viewXml('');
this.collListItem = oList.getItems(camlQuery);

clientContext.load(collListItem);

clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));  
}
function onQuerySucceeded(sender, args) {

var listItemInfo = '';

var listItemEnumerator = collListItem.getEnumerator();

while (listItemEnumerator.moveNext()) {
    var oListItem = listItemEnumerator.get_current();
    listItemInfo += '\nID: ' + oListItem.get_id() +             
        '\PageContent: ' + oListItem.get_item('PublishingPageContent');
}
console.log(listItemInfo); // returns ID and PageContent
}
function onQueryFailed(sender, args) {

alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

First, I would recommend to double check the internal name of your field, just in case.

do you access the data retrieved like this ?

function onSuccess(data, request) 
{
    var itemInfo = data.d;
    // if your rich text field internal name is "Description"
    alert(itemInfo.Description);
}

if your field is not here, can you try to modify the rest URL by adding

?$select=Title,MyCustomFieldInternalName

at the end. See if you can retrieve Title and your field.

EDIT It doesn't seem possible to retrieve the PublishingPageContent via REST in SharePoint 2010. It is in SharePoint 2013 : How to get content of html by using REST service in SharePoint 2013
