Making an attempt to ship HTTP Publish request to GDAX with auth. The ‘GET’ requests work superb and I am uncertain if I’m passing the json params appropriately as I preserve getting Unhealthy Request.
non-public static JsonObject LimitOrder(String image, boolean facet, String amount, String value)
{
BigDecimal dPrice = new BigDecimal(value);
BigDecimal dQuantity = new BigDecimal(amount);
String sSide = facet?"purchase":"promote";
String param ="{"measurement":""+dQuantity.toString()+"","value":""+dPrice.toString()+"","facet":""+sSide+"","product_id":""+image+"","post_only":true}";
attempt
{
String timestamp= Instantaneous.now().getEpochSecond()+"";
String accessSign = getAccess(timestamp,"POST","/orders");
String apiKey = properties.getProperty("key");
String passphrase = properties.getProperty("passphrase");
URL url = new URL("https://" + properties.getProperty("host") + "/orders");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setDoOutput(true); // Triggers POST.
connection.setRequestProperty("Content material-Sort", "software/json; charset=UTF-8");
connection.setRequestProperty("CB-ACCESS-KEY", apiKey);
connection.setRequestProperty("CB-ACCESS-SIGN", accessSign);
connection.setRequestProperty("CB-ACCESS-PASSPHRASE", passphrase);
connection.setRequestProperty("CB-ACCESS-TIMESTAMP", timestamp);

connection.setReadTimeout(5000);
// System.out.println("WRiting: " + param);
attempt (OutputStream output = connection.getOutputStream()) {
output.write(param.getBytes("UTF-8"));

String standing = connection.getResponseMessage();
System.out.println("STATUS: "+standing);
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer content material = new StringBuffer();
whereas ((inputLine = in.readLine()) != null) {
content material.append(inputLine);

System.out.println("Empty Response");
}
in.shut();
connection.disconnect();

}
and the entry signal technique under:
non-public static String getAccess(String timestamp, String technique, String path) throws NoSuchAlgorithmException, InvalidKeyException {
String secret = properties.getProperty("secret");
String prehash = timestamp+technique+path;
Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
byte[] secretDecoded = Base64.getDecoder().decode(secret);
SecretKeySpec secret_key = new SecretKeySpec(secretDecoded, "HmacSHA256");
sha256_HMAC.init(secret_key);
return Base64.getEncoder().encodeToString(sha256_HMAC.doFinal(prehash.getBytes()));
