API call to pull blog teaser and image

1. Is it possible to use API V2 (or V1) to pull blog teaser and the image.  If yes, please provide sample code (HTTP call). 2. Can the image be reformatted to a specific size using the API call?   ...

When doing an API call for messages with the label text "Events", I do see a field for teaser, but the value returned is one string:

"teaser" : "<P>&nbsp;<span class=\"lia-inline-image-display-wrapper lia-image-align-inline\" style=\"width: 480px;\"><img src=\"https://stage.liveopsnation.com/t5/image/serverpage/image-id/74iEAC9E1BB2EE4DFE6/image-size/large?v=1.0&amp;px=999\" alt=\"youcandoit.png\" title=\"youcandoit.png\" /></span></P>\n<P>This is the article teaser.</P>"

Accessing the image is not straightforward as it would if there were keys for each element of the string. So how do I return just the URL for the image and, separately, just the actual text from the teaser? String gymnastics? What's the best way to do this? Anyone have a code example?

After API call you will get teaser node

"teaser" : "<P>&nbsp;<span class=\"lia-inline-image-display-wrapper lia-image-align-inline\" style=\"width: 480px;\"><img src=\"https://stage.liveopsnation.com/t5/image/serverpage/image-id/74iEAC9E1BB2EE4DFE6/image-size/large?v=..." alt=\"youcandoit.png\" title=\"youcandoit.png\" /></span></P>\n<P>This is the article teaser.</P>"

Assign this teaser value into a variable like this in your <#list></#list>

 

 

<#assign messageTeaser = message.teaser?split("<img","i") >
<#assign messageTeaser?lower_case?contains("<img")>
<#assign images = messageBody?split("<img","i") >
<#assign getImageUrl = images[1]?split(" />","i") >
<#assign getImage="<img class='img' "+getImageUrl[0]+" />" />
${getImage}

 

Above code is to get first image from teaser.

If you want multiple images from teaser you can use

${images} in list
<#list images as image>

this will return all images from teaser under list
