The data sent by the POST request will be accessible through req.body, so the variable you are looking for is req.body.service. Also, assuming the function req.collection.findOne uses the property service of the first argument, you should keep the code as following: 

 req.collection.findOne({service: req.body.service}, function(e, result){
     //...
 });

Given that an object {req.body.service: ...} is invalid.
