JIRA API returns 405 errors. Works fine with curl

[Nathan Reddy]

I am trying to make a simple Jira REST API call from my Eclipse  to Jira Cloud. This works fine with curl on same machine using the same URL and same credentials. 

curl -D- -X GET -H "Authorization:Basic bmF0aGFuQHMODIFIEDBYME==" -H "Content-type:application/json" "https://tracecloud.atlassian.net/rest/api/2/issue/PID-7"

Response : 

HTTP/1.1 200 OK
Server: AtlassianProxy/1.19.3.1
vary: Accept-Encoding

I am trying the same thing in my Java code : 

     try {

             // Create URL object

            URL url = new URL("https://tracecloud.atlassian.net/rest/api/latest/issue/PID-7");

             conn = (HttpURLConnection) url.openConnection();

             conn.setDoOutput(true);

             conn.setRequestMethod("POST");

             conn.setRequestProperty("Content-Type", "application/json");

             conn.setRequestProperty("Authorization", "Basic bmF0aGFBase64JiraAPItoken==");

             os = conn.getOutputStream();

             os.write(input.getBytes());

             os.flush();

             System.out.println("response code is " + conn.getResponseCode());

             if(conn.getResponseCode() == 200){

                 br = new BufferedReader(new InputStreamReader((conn.getInputStream())));

                 while((output = br.readLine()) != null){

                     loginResponse += output;

                 }

                 conn.disconnect();

             }

         } catch (Exception ex) {

             System.out.println("Error in loginToJira: " + ex.getMessage());

             loginResponse = "ERROR";

         }

     System.out.println("loginResponse  is " +loginResponse);

I did some research and tried the following :

1. Used HTTPS

2. This URL works fine, but returns HTML web page and not JSON.      // URL url = new URL( "https://tracecloud.atlassian.net/jira/software/projects/PID/boards/1?selectedIssue=PID-1");

3.  conn.setRequestProperty("dataType", "json");

 4. conn.setRequestProperty("cache-control", "no-cache");

  5.  conn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");

I used to get 403 error, now I get 405 . Any help is much appreciated.

Hi Nathan,

In the java code you're performing a POST method, in curl you use a GET method.

That's most likely your issue.

Hi Charlie,

Thanks for the response. I had tried it with GET too. Same issue (405) error

             conn = (HttpURLConnection) url.openConnection();

             // Set properties

             conn.setDoOutput(true);

             conn.setRequestMethod("GET");

             conn.setRequestProperty("Content-Type", "application/json");

            // conn.setRequestProperty("dataType", "json");

             // this encoding is for nathan@tracecloud.com:JIRAAITOKEN

             conn.setRequestProperty("Authorization", "Basic bmF0aGFuQHRyYW

....
