Unable to POST and PUT using OAuth for REST APIs

Jira Development

I was able to GET and DELETE, but I was not able to POST or PUT. I was able to make all calls using Basic Authentication but not OAuth. I followed the tutorial from https://developer.atlassian.com/cloud/jira/platform/jira-rest-api-oauth-authentication/ . The example only uses GET. I used the same API for POST, PUT, and DELETE which is required to create, edit and delete a a JIRA issue.

I get the com.google.api.client.http.HttpResponseException: 400 Bad Request
{"errorMessages":["Can not instantiate value of type [simple type, class com.atlassian.jira.rest.v2.issue.IssueUpdateBean] from JSON String; no single-String constructor/factory method"]}
It appears to be a common problem from a quick Google search, but I am unable to find a solution. Could you point me to the right resources to make it work – forums or other source of development help.
For example, I tried to make a POST call to create an issue passing in this JSON:

{
  "fields": {
    "summary": "JUNIT testCreateDeleteIssue() Tue Oct 03 13:57:25 EDT 2017",
    "issuetype":
      { "name": "Bug" },
    "project":
      { "key": "HELLO" }
  }
}

I get the following error:

com.google.api.client.http.HttpResponseException: 400 Bad Request
{"errorMessages":["Can not instantiate value of type [simple type, class com.atlassian.jira.rest.v2.issue.IssueUpdateBean] from JSON String; no single-String constructor/factory method"]}
	at com.google.api.client.http.HttpRequest.execute(HttpRequest.java:1070)

Code use to create HttpContent:
HttpContent content = new JsonHttpContent(new JacksonFactory(), jsonString);

Code to POST

HttpRequestFactory requestFactory = nt.createRequestFactory(parameters);
HttpRequest request = requestFactory.buildPostRequest(jiraUrl, content);
request.execute();

From the docs:

The fields, that can be set on an issue create operation, can be determined using the /rest/api/2/issue/createmeta resource. If a particular field is not configured to appear on the issue’s Create screen, then it will not be returned in the createmeta response. A field validation error will occur if such field is submitted in request.

Have you called createmeta to ensure that you have a “Bug” issuetype?

Also in the example for create issue the issueType is being passed an id of the issue type instead of the name.

Try that and let me know if that works for you?

Thanks,

I will try within the hour. But to let you know, I pass in the exact info using basic authentication and it works. It just doesnt work for OAuth using the same libs in the tutorial. I am curious why the tutorial only show GET calls and not the others.

4

I received the exact same error. Is that error generated from server or the client?

Do you have sample code for a POST call for the linked tutorial? That tutorial only shows GET calls.

5

anymore ideas? Curious to know why the tutorial doesn’t have a POST example when it is clearly needed to create a JIRA issue.

Hi, @alex.phung.

I created a rough example based on what you started with, and was able to make it work. For the JSON string, I used GenericData like these instead of a String:

        GenericData myData = new GenericData();
        
        GenericData projectData = new GenericData();
        projectData.put("key", "HELLO");

        GenericData issueTypeData = new GenericData();
        issueTypeData.put("name", "Bug");        
        
        GenericData fieldsData = new GenericData();
        fieldsData.set("summary", "TEST SUMMARY");
        fieldsData.set("issuetype", issueTypeData);
        fieldsData.set("project", projectData);
        
        myData.put("fields", fieldsData);

For the HttpContent:

HttpContent content = new JsonHttpContent(new JacksonFactory(), myData);

That should solve the challenges you faced. Cheers!
Ian

It works. Thank you. Can you point me to the documentation for GenericData and its use. I am looking for a better way to generate GenericData or JsonData from a JSON string or JSON Object.

Edit – actually, I was able to make this work by converting the JSON string into a JSON object.

Glad you made it work @alex.phung. Yes, JSONObject is also a valid (and sometimes a cleaner) approach.

In order to help other people who might experience the same problem, kindly mark the answer to guide them. Thanks!

I use com.google.gson.Gson to convert objects to/from JSON:
private final Gson GSON = new GsonBuilder().setPrettyPrinting().create();

Instead of passing in a string or GenericData, I pass in a JSON object. Convert the JSON string into Object.class:
Object jsonObject = GSON.fromJson(jsonString, Object.class);
HttpContent content = new JsonHttpContent(new JacksonFactory(), jsonObject);

This is a little awkward in converting an object (e.g., JIRAIssue) to a JSON string and then back to an OBJECT, but I have existing code that passing in a string to POST/PUT when using basic authentication. I may refactor my code to cleanly handle both basic authentication and OAuth later.

Code to POST (or PUT) is the same:
HttpRequestFactory requestFactory = nt.createRequestFactory(parameters);
HttpRequest request = requestFactory.buildPostRequest(jiraUrl, content);
request.execute();

I confirm that this solution works.

In order to help people, I’ll soon provide full source code with spring boot application.
