Ich versuche, private Daten auf GDAX anzufordern, bekomme aber immer wieder schlechte Anfragen. Kann nicht herausfinden, was ich falsch mache. Bitte helfen Sie.
private static JsonObject getAuthenticatedData() {
try {
String accessSign = getAccess();
System.setProperty("http.agent", "Java Client");
URL url = new URL("https://api.gdax.com/accounts");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod("GET");
con.setRequestProperty("CB-ACCESS-KEY", "accesskey");
con.setRequestProperty("CB-ACCESS-SIGN", accessSign);
con.setRequestProperty("CB-ACCESS-TIMESTAMP", ""+System.currentTimeMillis() / 1000L);
con.setRequestProperty("CB-ACCESS-PASSPHRASE", "passphrase");
con.setRequestProperty("Content-Type", "application/json");
con.setConnectTimeout(5000);
con.setReadTimeout(5000);
String status = con.getResponseMessage();
System.out.println(status);
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer content = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
content.append(inputLine);
}
System.out.println(content);
in.close();
con.disconnect();
}catch(Exception e) {
e.printStackTrace();
}
return null;
}
Und das:
public static String getAccess() {
//Set the Secret
String secret = "secret==";
//Build the PreHash
String prehash = Instant.now().toEpochMilli()+"GET"+"/accounts";
String hash = null;
try {
Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(), "HmacSHA256");
sha256_HMAC.init(secret_key);
hash = Base64.encodeBase64String(sha256_HMAC.doFinal(prehash.getBytes("UTF-8")));
hash = hash.replace("\n", "");
System.out.println(hash);
}
catch (Exception e){
e.printStackTrace();
}
return hash;
}
Können Sie versuchen, mit den folgenden Codezeilen in Ihren Methoden hinzuzufügen / zu ändern:
privates statisches JsonObject getAuthenticatedData() { String timestamp = Instant.now().getEpochSecond() + ""; String accessSign = getAccess(timestamp); con.setRequestProperty("CB-ACCESS-TIMESTAMP", Zeitstempel); con.setRequestProperty("akzeptieren", "application/json"); }
öffentlicher statischer String getAccess(String timestamp) { String prehash = timestamp+"GET"+"/accounts"; byte[] secretDecoded = Base64.getDecoder().decode(secret); SecretKeySpec secret_key = new SecretKeySpec(secretDecoded, "HmacSHA256"); hash = Base64.getEncoder().encodeToString(sha256_HMAC.doFinal(prehash.getBytes())); Hash zurückgeben; }
