using spring RestTemplate and 2 factor authenication to add issues to github

Last month, I figured out how to use Spring’s RestTemplate to add issues to github programmatically figuring it would save me time in the future.  Well, the future is here.  I needed to add 16 issues (one per milestone.)  I run my program and get a 401.  In particular, I got

Apr 20, 2014 6:42:18 PM org.springframework.web.client.RestTemplate handleResponseError

WARNING: GET request for "https://api.github.com/repos/boyarsky/repoName/issues" resulted in 401 (Unauthorized); invoking error handler

Right.  I’ve changed my password AND enabled two factor authentication on github in the past month.  Luckily, it was easy to switch my program to two factor.  Here’s what I did.

Create personal use token

I created a second personal use token just like I did for for my git commmand line use by going to the applications page and clicking “generate new token”.  I chose to create a separate token so I could revoke access as soon as I’m done running the web service.

Testing the token

Per the getting started with oauth doc, I ran a command line to test the token:

curl -i -H 'Authorization: token notMy40CharToken' \

https://api.github.com/user

 Wrote another trial program

I adapted my second trial program from the initial iterations to test out two factor.

package jb;

import org.springframework.http.*;
import org.springframework.web.client.*;

/**
 * Call a web service that uses authenticated user to test passing credentials
 *
 * @author jeanne
 *
 */
public class Trial3 {

	public static void main(String[] args) {
		String url = "https://api.github.com/repos/boyarsky/oca-ocp-book/issues";

		HttpHeaders headers = new HttpHeaders();

		String personalToken = "notMy40CharToken";
		headers.add("Authorization", "token " + personalToken);

		// ignore result because just testing connectivity
		HttpEntity<String> request = new HttpEntity<String>(headers);
		RestTemplate template = new RestTemplate();
		template.exchange(url, HttpMethod.GET, request, Object[].class);
		System.out.println("success");
	}

}

I then replaced the authentication part of my real program and it worked like a charm.  Even with the changes to the program, it was faster than creating 16 issues by hand with the proper text/assignee/milestone.

Delete the personal token

I deleted the token to ensure it never gets used again.  I don’t want to run the program by accident with my credentials.  Or accidentally post the token here.
