parameter based different result format

My task is to write a program to store files in object store. One of the subtasks requires to send json or xml format response to the file uploader/downloader as requested by client. The following rules must be followed:

                         entry                         
               +-------------------------+             
               v                         v             
           upload                      download        
       +-----------+              +--------------+     
       v           v              v              v     
    succ          err            succ           err    
  +-----+       +-----+                       +-----+  
  v     v       v     v                       v     v  
json1  xml1    json2  xml2                  josn2  xml2

1. if user uploads file with success, return json/xml type 1


2. if user uploads file with error, return json/xml type 2


3. if user downloads file with success, do nothing


4. if user downloads file with error, return json/xml type 2

I've managed to solve the task but I'm not satisfied with the class dependencies I got. I think mixture of abstract factory and strategy are suitable for the issue. Can you give me a hint how to deal with the problem?
