How to get Reactions ?

[Samir Issa]

Hi  ! 

I using restFB 2.0.0-rc3 , i´m trying to get Reactions , but all the time get null , the post has 900 reac.

i tried that , may be wrong ?

            Connection<Reactions> reactionsConnection = facebookClient29.fetchConnection("176934912345768_1531928753513037/reactions", Reactions.class);

                int count=0;                

                for( List<Reactions> reac : reactionsConnection){

                 

                 for (Reactions reaction : reac) {

                      

                  for(ReactionItem reactionItem :reaction.getData()){

                    

                   out.println("Reactoins: " + reactionItem.getName());

                   out.println("Reactoins: " + reactionItem.getType());

                   count++;

                  }

                }

                out.println("Total reactions: " + count);

                     

                }

Hi Samir,

you should try:

Connection<Reactions.ReactionItem> reactionsConnection = facebookClient29.fetchConnection("<post-id>/reactions", ReactionItem);
for (List<Reactions.ReactionItem> reactions : reactionsConnection) {
   for (Reactions.ReactionItem reactionItem: reactions) {
       out.println("Reactions name: " + reactionItem.getName());
       out.println("Reactions type: " + reactionItem.getType());
   }
}

Do you need all reactions, or only the count? Then you have other possibilities …

Cheers

all reactions from each posts !!

Okay, 

then you need to use the above solution.

Fetching only the count of reactions (even splitted up into the different reaction types) is much easier, but in your case you really have to run through all the loops. 

Reactions are paged, so using the endpoint is necessary. 

You can save some calls, if you check on fetching the posts their reaction count and only fetch the reactions if there are any.
