Rest service param passing

aqaadi · November 8, 2017, 10:38pm

Hi Team,

I’m trying to consume a rest service in my camunda flow.

I need help in passing the context root part for the rest from “http-connector” in BPMN flow.

For example my rest service could be like : http://feiertage.jarmedia.de/api/<DYNAMIC_TEXT_PARAM>

I want to pass the above bold part as a dyanmic text param. Any idea how i can do it and how to store the result of the rest service in a variable.

Below is the sample screen shot of config.

Save your dynamic part as a process variable and then use the expression:

http://example.com/dog=${myProcessVarName}

see https://medium.com/@stephenrussett/handling-government-business-processes-across-administrative-divisions-digitalstate-406f86d4fd56 for further examples.

See the response variable name which is that you return or process in your output parameter.

Hi Stephenn,

I tried passing the param as suggested in your example and I see this:

Ya sorry that was not the right way to do that.

Better way:

use Script type. javascript

var base = 'http://54.169.27.73:5000/fuzzyMatch/';
var value = execution.getVariable('CaseType');
var url = base + value;
url;

aqaadi · November 9, 2017, 2:55am

This would work ?

StephenOTT · November 9, 2017, 3:03am

well make sure the var value = is on the second row.
and the var url stuff is on the third row

but yes

aqaadi · November 9, 2017, 3:10am

Thanks alot Stephen. This went through.

However the response variable is getting set to NULL. The ideal value it could hold based on rest service response in “UNKNOWN”.

Any idea how we can obtain this?

Config:

StephenOTT · November 9, 2017, 3:13am

Whats the json look like that is the response?

See the medium article again for the response pattern.

typically you can do this with:

Script:javascript

response;

Use Camunda SPIN https://docs.camunda.org/manual/7.7/reference/spin/json/01-reading-json/ to convert the string into a json object.

aqaadi · November 9, 2017, 3:21am

The rest service response is string, should I be converting the response to json

StephenOTT · November 9, 2017, 3:32am

Generally i feel its better to always have a JSON response. Things tend to be a lot easier

aqaadi · November 9, 2017, 3:36am

Using spin can I convert the string response to json object. I’m trying it let me share the results

aqaadi · November 9, 2017, 3:44am

Tried the below but was not successful:

Config

script:

// fetch execution variables
var response = connector.getVariable(“CaseType”);
// parse response variable with camunda-spin
var CaseType = S(response);
CaseType;

its just S(response); which foes in the parseHoliday.js file.

No need for the extra.

aqaadi · November 9, 2017, 4:07am

So are we saying S(response); and the response object would be assigned to CaseType output parameter ?

aqaadi · November 9, 2017, 4:33am

Hi Stephen,

I tried with S(response) as well and still it throws the same exception.

If I have to get the response in JSON. Any idea how should the JSON response structure be for ease of use.

Thanks in advance for your valuable inputs.

StephenOTT · November 9, 2017, 4:36am

Any JSON you want. But it needs to be valid json.

This worked thanks @StephenOTT
