Java wrapper for the 1.1 version of the Bittrex API. Methods return a String with the response in JSON format, and can then easily be requested for information by converting them into a map using the static getMapsFromResponse() method.
public static void main(String...args) {
Bittrex wrapper = new Bittrex();
wrapper.setAuthKeysFromTextFile("keys.txt");
String rawResponse = wrapper.getMarketSummary("BTC-LTC");
List<HashMap<String, String>> responseMapList = Bittrex.getMapsFromResponse(rawResponse);
// In some cases, only 1 map is actually returned - if this is assured:
HashMap<String, String> onlyMap = responseMapList.get(0);
// See available information using present keys
for(String key : onlyMap.keySet())
System.out.print(key + " ");
System.out.println();
// Get wanted value using a key found in the KeySet
onlyMap.get("Volume");
// Some responses have more than 1 map - the List must be traversed in these cases.
String otherRawResponse = wrapper.getBalances();
List<HashMap<String, String>> allBalancesMapList = Bittrex.getMapsFromResponse(otherRawResponse);
for(HashMap<String, String> map : allBalancesMapList)
System.out.println(map);
// And then the wanted map can be used
allBalancesMapList.get(3).get("Balance");
}
Additionally, if a constant internet connection isn't available, connection attempts & handling of connection failures can be specified in the constructor, with the handling of the ReconnectionAttemptsExceededException.
// Construct wrapper object with 3 connection attempts, and a 10 second delay between each attempt.
Bittrex wrapper = new Bittrex(3, 10);
wrapper.setAuthKeysFromTextFile("keys.txt");
try {
final String response = wrapper.getBalance("DOGE");
System.out.println(response);
System.out.println(Bittrex.getMapsFromResponse(response).get(0).get("Balance"));
System.out.println(Bittrex.getMapsFromResponse(wrapper.getBalance("BTC")).get(0).get("Balance"));
// If all 3 attempts fail, an unchecked exception is thrown, and can be handled with a simple try/catch.
} catch (ReconnectionAttemptsExceededException e) {
System.err.println("Connection failed.");
}
Please attach your key & secret in a text file, with the following format, and place it in the same folder as the source code.
- apikey: "key"
- secret: "secret"
