Question

I’m currenty trying to extract information from a website’s API JSON output.
Here is what I have, and it almost works perfectly:

def get_player_stats
  uri = URI("http://elophant.com/api/v1/euw/getPlayerStats?accountId=#{CGI.escape(@summoner.acctId)}&season=CURRENT&key=KEYID")
  resp = Net::HTTP.get_response(uri)
  hash = JSON(resp.body)

  solo_ranked_elo = hash['playerStatSummaries']['playerStatSummarySet'][2]['maxRating']
  puts solo_ranked_elo

end

The problem is that the ['playerStatSummarySet'][1] values will change depending on the player. So for one player their maxRating would be in set [1], but another player’s maxRating will be in set [6].

I need to search for the set where the RankedSolo5x5 value exists then I can go about outputting the maxRating. How would I go about this?

Here are two example files I’m using for comparison:

http://elophant.com/api/v1/euw/getPlayerStats?accountId=22031699&season=CURRENT&key=KEYID

http://elophant.com/api/v1/euw/getPlayerStats?accountId=23529170&season=CURRENT&key=KEYID

I hope that is clear enough!

Here’s a full example

#!/usr/bin/env ruby

require 'net/http'
require 'uri'
require 'json'

uri = URI("http://elophant.com/api/v1/euw/getPlayerStats?accountId=#{ARGV[0]}&season=CURRENT&key=KEYID")
resp = Net::HTTP.get_response(uri)
stat_summary = JSON(resp.body)['playerStatSummaries']['playerStatSummarySet']

stat_summary.each_with_index do |obj, i| # it's this loop that answers your question
  next if obj['playerStatSummaryType'] != 'RankedSolo5x5'

  puts obj['maxRating']
  break
end

ARGV[0] is a command line argument value for the accountID. You’d save the above to some max_rating file, chmod +x max_rating and then run

./max_rating 22031699       # Outputs 1421
./max_rating 23529170       # Outputs 1237
