add watcher json syntax used for jira rest api (java jersey classes)

[TraollyX]

Hello Community,

I'm trying to add a watcher to an existing jira issue with java jersey classes (JIRA Rest api).

I need to pass in the json syntax to get it work, but it keeps returning a 400. Any help on what the correct json syntax to use?

ex)

//**************************************************************

// Add watcher to an existing JIRA issue

//**************************************************************

public void add_jira_Watcher(String issue_ID, String watcher) {

try {

String ji_rest_edit_URL = "http://"+ji_Host+"/rest/api/2/issue/"+issue_ID+"/watchers";

final String json_add_Watcher = "{\"username\": \"+watcher+\"}";

System.out.println("URL: " + ji_rest_edit_URL);

WebResource webResource = client.resource(ji_rest_edit_URL);

ClientResponse response = webResource.header("Authorization", "Basic " + auth_base_64).type("application/json").accept("application/json").post(ClientResponse.class, json_add_Watcher);

@SuppressWarnings("deprecation")

int statusCode = response.getResponseStatus().getStatusCode();

if (statusCode != 204) {

jrest_API_Logger.info("add_jira_Watcher() --> Watcher added failed to issue "+issue_ID+": "+statusCode);

} else {

System.out.println("wachter: " + watcher + " was added to jira issue: "+issue_ID+": "+statusCode);

}

} catch (ClientHandlerException ex) {

jrest_API_Logger.info("add_jira_Watcher() ClientHandlerException ex.getMessage(): " + ex.getMessage() + ": " + issue_ID);

} catch (Exception ex) {

jrest_API_Logger.info("add_jira_Watcher() Exception ex.getMessage(): " + ex.getMessage() + ": " + issue_ID);

}

}

Thanks in advance.

I found that the parameter variable needed the quotes. Code solution below:

....

public void add_jira_Watcher(String issue_ID, String watcher) {

try {

.....

ClientResponse response = webResource.header("Authorization", "Basic " + auth_base_64).type("application/json").accept("application/json").post(ClientResponse.class, "\""+watcher+"\"");

.......

}

.....

Hope this helps anyone.

Yes I've tried that as well and still get an 400 error response.

final String json_add_Watcher = "\"trx\"";

Thoughts?

change the input string something like this

final String json_add_Watcher = "{\"+watcher+\"}";

the input param should allow only name of th watcher, check here for input params

I've tried both the below and still get an 400 error for both.

final String json_add_Watcher = "{\"+watcher+\"}";

final String json_add_Watcher = "{"+watcher+"}";

Thoughts on other things I can try?
