How to avoid escaping of JSON in REST message POST call?

mg85 · ‎10-13-2014

There is a REST message defined in Service Now.

The POST call in the REST message has a variable ${content} in its content field.

And a REST Message Function Parameter called "content" is defined with a valid JSON as string:

{"result":{"upon_approval":"proceed","reason":"",................................

But, testing this service shows that all quotes in the JSON above are escaped. Input content sent to the REST Message call looks like this:

{"result":{"upon_approval&quot.................................

Is there a way to avoid this auto escape? I faced the same problem when I tried to call this REST message from a script too.

Some of the options I tried in the script:

JSONParser(), JSON.encode()

Hey,

I have checked a REST message that uses JSON in my system and here is a snippet, maybe this will help. This posts incidents to Jira..

So we start but running a business rule and create an object...

var issue = new Object();


issue.fields = new Object();


issue.fields.project = new Object();


issue.fields.project.key = gs.getProperty("com.snc.integration.jira.project");


issue.fields.summary = ""+current.short_description;


issue.fields.issuetype = new Object();


issue.fields.customfield_10025 = ""+current.number;


issue.fields.issuetype.name=""+current.subcategory;


issue.fields['customfield_'+j.sysidField] = j.getSysIdPrefix()+":"+current.sys_id;


issue.fields.priority = new Object();


issue.fields.priority.id = j.getJiraPriority(""+currentPriority);


if(j.verbose == "true"){


   JSUtil.logObject(issue);


}

We then pass that object into a script include and the function to create in incident via rest message is below..

var jiraIssue = j.createIssue(issue);




               var json = new JSON();


               var body = json.encode(issue);


               var r = new RESTMessage('Jira Issue', 'post');


               r.setBasicAuth(gs.getProperty('com.snc.integration.jira.jira_api_user'), gs.getProperty('com.snc.integration.jira.jira_api_password'));


               r.setXMLParameter('issuebody', body);


               r.setStringParameter('base_endpoint', gs.getProperty('com.snc.integration.jira.base_jira_instance_url'));


               var res = this._submitBodyTypeRequest(r, true);


               return res;

Let me know if this helps with your troubles?
