authentication keystone httpUrlconnection java

Asked by rihab

Hi!
I'm trying to get connected to openstack through a curl. I used the following curl:

curl -i 'http://10.0.10.15:5000/v2.0/tokens' -X POST -H "Content-Type: application/json" -H "Accept: application/json" -d '{"auth": { "passwordCredentials": {"username": "adm", "password": "pwd"},"tenantName":"adm"}}'

I would like to convert this curl to a java code using httpurlConnection. I used the following code:

                               String url="http://10.0.10.15:5000/v2.0/tokens";
          URL object=new URL(url);
    HttpURLConnection con = (HttpURLConnection) object.openConnection();
    String username="adm";
    String password="pwd";
    String userpass=username+":"+password;
    String basicAuth = "Basic " + javax.xml.bind.DatatypeConverter.printBase64Binary(userpass.getBytes());
    con.setDoOutput(true);
    con.setDoInput(true);
    con.setRequestProperty("Content-Type", "application/json; charset=utf8");
    con.setRequestProperty("Accept", "application/json");
    con.setRequestMethod("POST");
    con.setRequestProperty ("Authorization", basicAuth);
    con.setRequestProperty("X-Auth-Token", "admin");
                                /.....
I didn't write all the code. any way, my problem here is that I get 401 not authorized. while the curl gives me the following result:

HTTP/1.1 200 OK
Vary: X-Auth-Token
Content-Type: application/json
Content-Length: 1715

I don't know am I missing some thing in the code. Is there a problem in authentication code?
Thank you in advance!

you are using basic auth. You need to post json data. Java is too verbose to write the whole code.

If you are just trying it as an example, then have the json in file, and read the the file contents in string. Then post the string Our u can build json using GsonBuilder

sendRequest(String requestReadFromFile){

                       String url="http://10.0.10.15:5000/v2.0/tokens";
          URL object=new URL(url);
    HttpURLConnection con = (HttpURLConnection) object.openConnection();

    con.setDoOutput(true);
    con.setDoInput(true);
    con.setRequestProperty("Content-Type", "application/json; charset=utf8");
    con.setRequestProperty("Accept", "application/json");
    con.setRequestMethod("POST");

  //Send request
      DataOutputStream wr = new DataOutputStream (
                  con.getOutputStream ());
      wr.writeBytes (requestReadFromFile);
      wr.flush ();
      wr.close ();

      //Get Response
      InputStream is = con.getInputStream();
      BufferedReader rd = new BufferedReader(new InputStreamReader(is));
      String line;
      StringBuffer response = new StringBuffer();
      while((line = rd.readLine()) != null) {
        response.append(line);
        response.append('\r');
      }
      rd.close();

   System.out.println(respone)

}

Can you help with this problem?
