Logging into REST api via Java

[stealthrt]

Hello!

I've been trying to get my Java code working with the Jira server rest api v2.

I currently have this code:

private static final String JiraBase = "https://mycompanyurl.com"
private static final String JiraEmail = "myemail@mycompanyurl.com"
private static final String PAT = "ljknfg9u8h5h9nner9gbner098honeg+on"

try {
    String apiURL = JiraBase + "/rest/api/2/myself";

    rustManager[] trustAllCertificates = new TrustManager[] {
    new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {return null;}
        public void checkClientTrusted(X509Certificate[] certs, String authType){}
        public void checkServerTrusted(X509Certificate[] certs, String authType){}
    }
};

SSLContext sslContext = SSLContext.getInstance("TLS");

sslContext.init(null, trustAllCertificates, new SecureRandom());

SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();

String auth = JiraEmail + ":" + PAT;
byte[] encodedAuth = Base64.getEncoder().encode(auth.getBytes(StandardCharsets.UTF_8));
String authHeader = "Basic " + new String(encodedAuth);

connection.setRequestMethod("GET");
connection.setRequestProperty("Authorization", authHeader);
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Type", "application/json");
connection.setSSLSocketFactory(sslSocketFactory);

int responseCode = connection.getResponseCode();

if (responseCode == HttpURLConnection.HTTP - oK) {
    BufferedReader in = new BufferedReader(
        new InputStreamReader(connection.getInputStream()))
    );

    String inputLine;
    StringBuilder response = new StringBuilder();

    while ((inputLine = in .readLine()) != null) {
        response.append(inputLine);
    }

    in .close();
    System.out.printLn("Response: " + response.toString());
} else {
    System.out.printLn("GET request failed");
}

Does anyone see anything I am missing?

It's just odd that I can access /rest/api/2/myself from the web browser but not in the Java app. The response code I get is 403 in the java app.

This is rather over complicating it but since this is tagged as server, I suspect you're not setting the right auth header?

If that is a "real" PAT, then you'd only do "Bearer <PAT>". If it's basic username:password, then it would be "Basic <base64 user:pass>". So just to make sure because the snippet says PAT but you're using it as a password.

Thank you! It was because of having basic instead of bearer!

Hi @stealthrt

I don't see any specific error with your code, but I would suggest you to use a tool like Postman to test the API endpoint and authentication. This can help you isolate the issue and determine if it's a problem with the Java code or the Jira instance.

Additionally, we have a developer community and you can check there for better guidance:
