Sending a REST Message with no REST Message Record for incident records

[arulvelu]

Hi Folks , I   have written this script to check for active incidents that had happened few minutes ago and send this details to 3rd party rest api (   node server   written by me) .

sendNewIncidents();

function sendNewIncidents() {

  var d = new Date();

  var gr = new GlideRecord('incident');

  gr.addQuery('priority',1);

  gr.addQuery('impact',1);

  gr.addQuery('active',true);

  gr.addQuery('sys_created_on','>=', gs.minutesAgo(560));

      gr.query();

  var incident = {};

      var incidentList = [];

  while (gr.next()) {

  incident = {};

      gs.addInfoMessage(gr.number);

  gs.addInfoMessage(gr.short_description);

  gs.addInfoMessage(gr.category);

  gs.addInfoMessage(gr.cmdb_ci);

  incident.number =   gr.number + '';

  incident.cmdb_ci = gr.cmdb_ci.value + '';

  incident.desc = gr.short_description +'';

      incident.openTime = gr.opened_at + '';

  incident.category = gr.category+ '';

  incidentList.push(incident);

  }

      gs.log("Lenght is:"+incidentList.length);

      for(i=0;i<incidentList.length;i++) {

  var incidentDetails = incidentList[i];

  gs.log (JSON.stringify(incidentDetails));

      var dataSend =   JSON.stringify(incidentDetails);

  var stringData= new global.JSON().encode(dataSend);

  gs.log(stringData);

  var restMessage =   new sn_ws.RESTMessageV2();

      restMessage.setHttpMethod("post");

      restMessage.setEndpoint("http://12.12.14.25/incident/");

      restMessage.setRequestBody(stringData);

      var response = restMessage.executeAsync();

  gs.log(JSON.stringify(response));

  }

}

I am creating a restmessage with no message record in the forloop and posting it to my http endpoint "http://12.12.14.25/incident/" and doing this in async way. When i execute this script, i am debugging the response in node server where i get only { } . This as result. Please let me know where i have gone wrong. Thanks Arul

1. What is this target "http://12.12.14.25/incident/" ?

2. Do you see an inbound JSON at target?

3. Do you see a response being sent out from Target?

4. What is your ServiceNow instance version? If you are on Istanbul/Jakarta: we have something called HTTP logging:

Outbound web services logging

5. What do you see in these logs?

6. Have you tried testing REST Requests to your target "http://12.12.14.25/incident/" via tools like POSTMAN? I recommend Test and debug.

1.   What is this target "http://12.12.14.25/incident/" ? - This Http endpoint created by me which accepts the Post requests. 2. Do you see an inbound JSON at target? No sure what u are asking 3.Do you see a response being sent out from Target? whne i log the response . I am seeing {} this . 4 and 5 the point. I am will use this logging and post the results. 6. Have you tried testing REST Requests to your target "http://12.12.14.25/incident/" via tools like POSTMAN? I recommend Test and debug -   I have tried posting array of json object using postman and my http endpoint is able to receive it. Vab singhal , My query is am i following the correct way to send a rest message using RestMessageV2() or any other method is available for it. Thanks Arul

hi,

it is working without any problem.

// now script - run in background

var gr = new GlideRecord('incident');

gr.get('d71f7935c0a8016700802b64c67c11c6');

var str = JSON.stringify(gr);

var restMessage = new sn_ws.RESTMessageV2();

restMessage.setHttpMethod("post");

restMessage.setEndpoint("http://localhost:4000/incident");

restMessage.setRequestBody(str);

var response = restMessage.execute();

gs.addInfoMessage(JSON.stringify(response.getBody()));

node - server:

var http = require('http');

//create a server object:

http.createServer(function (req, res) {

    req.on('data', function(data){

    var str = data.toString();

    res.write('Hello World!'); //write a response to the client

    res.write(str);

    res.end(); //end the response

  })

}).listen(4000); //the server o

But if i use the "express" server , then i am getting empty response just like you said. Hope this helps.

updated script:-

now script:-

var gr = new GlideRecord('incident');

gr.get('d71f7935c0a8016700802b64c67c11c6');

var str = JSON.stringify(gr);

var restMessage = new sn_ws.RESTMessageV2();

restMessage.setHttpMethod("post");

restMessage.setEndpoint("http://localhost:4000/incident");

restMessage.setRequestBody(str);

var response = restMessage.executeAsync();

response.waitForResponse(60);

gs.addInfoMessage(JSON.stringify(response.getBody()));

express router for "incident" path:-

router.post('/', function(req, res, next) {

    var body = [];

    req.on('data', function(data) {

    /*console.log(JSON.stringify(data));

  this is working for postman

  var msg = {

  msg: 'incident list recieved',

  body: JSON.stringify(data),

  body1: req.body

  }

  res.send(msg); */

    body.push(data);

  }).on('end', function() {

    var str = JSON.parse(body.toString());

    res.send({

    msg: 'hello world',

    body: str

  });

  });

Thanks

Hi Lakshmi , I have slightly modified my code . I used setRequestHeader("Content-Type","text/plain") in the script actions code and modified my node js code ( i am using express )   var   app = express(); var bodyParser = require('body-parser'); app.use(bodyParser.urlencoded({ extended: false})); app.use(bodyParser.text({ type: 'text/*' })); with this modification i am getting body content as "{\"number\":\"INC0010039\",\"cmdb_ci\":\"alex-test\",\"comments\":\"\",\"desc\":\"Mobile not working due to Low battery\",\"openTime\":\"2017-09-05 08:42:17\",\"category\":\"software\"}" Appreciate your help and thanks for your response 🙂 Regards Arul
