Http-connector and assigning output results to an instance variable

Hello,

I am generally new to Camunda and not a developer.

We are trying to approach the creation of a user task to perform a REST GET from a webservice using the Connector and http-connector type and trying to capture the results in an output variable.

Following the REST example on GitHub, the “url” and “method” input parameters are added.

We are also trying to capture the results in a text variable called WSresults.

So far all the attempts, have not produced any values when inspected the WSresults variable using Cockpit to look at the instance data.

Further, we have not seen any entries in the log files to indicate any failures.

Is what what we would like to do possible?

Thank you

Hi,

I am assuming you are using a service task with a connector? That being the case, I tend to use a script in the connector config to process the result. Your script can return a single result which will populate the value of a return variable. If you need to parse the response to break it into multiple pieces and thus create multiple process variables, you can call connector.setVariable(,). At its simplest, a groovy script such as the one below may help you debug…

//
// print response to console…
//
println response

//
// Create a new process variable
//
connector.setVariable(“MyConnectorVariable”,response)

//
// return response
response

regards

Rob

Check out: https://medium.com/@stephenrussett/handling-government-business-processes-across-administrative-divisions-digitalstate-406f86d4fd56#.q5uqxq1la and use that bpmn example as a base for connecting and manipulating data from the web service.

Also: add a “placeholder” user task at the end of your process to place your process in a wait state so you can inspect the process variables through Cockpit

Rob,

Thank you. I am working through the examples.

Stephen,

This example is very helpful and I am making progress.

The service results are now collected in the instance variable and we are now attempting to figure out the proper way to navigate the JSON nodes to select the data parts we want from that result set.

We are looking for some good references to understand the .prop, .elements, parsing.

Thank you

Paul

See: https://docs.camunda.org/manual/7.6/reference/spin/json/01-reading-json/

Stephen,

We now have a working request and are able to parse the JSON.

Since your examples are so great … :slight_smile:

Do you have examples of:

  1. The ability to parameter-ize the url input parameters from a business flow instance and
  2. A way to capture/map many of the JSON values and store then into individual business flow variables

Example
Var 1 = node.element.prop1.value
Var 2 = node.element.prop2.value
etc

Thank you again

Paul

Stephen,

I have this working …

//DOT Authority
var DOTAuthority = S(response).prop(“content”).elements().get(0).prop(“carrierAuthority”).prop(“authority”).value();
connector.setVariable(“DOTAuthority”, DOTAuthority );

//DOT Number
var DOTNumber = S(response).prop(“content”).elements().get(0).prop(“carrierAuthority”).prop(“dotNumber”).value();
connector.setVariable(“DOTNumber”, DOTNumber );

Is there a more efficient way?

Thank you for all your help.

Paul

@Paul_McCauley i would say thats the most efficient way. Looks good.

You could write

var carrier = S(response).prop("content").elements().get(0).prop("carrierAuthority");
var authority = carrier.prop("authority").value();
// do something

var number = carrier.prop("dotNumber").value();
// do something

as a micro optimization :cocktail:

To select the carrier, you could use json path (via S(response).jsonPath(...)) to make the code more concise.

That is better :slight_smile:

Thank you all.

The feedback is very helpful.

Any ideas on how to create a parameterized URL request?

the URL I am currently testing with is …

The root of the url is: https://mobile.fmcsa.dot.gov/qc/services/
the endpoint is: carriers/44110/authority?
access key: webkey=longnumberhere

We would like to be able to:

  1. use an instance variable in the endpoint like: carriers/$ { dotNumber } /authority?
  2. use a variable to include the webkey value

So in the end, a url call something like:

https://mobile.fmcsa.dot.gov/qc/services/carriers/${ dotNumber }/authority?webKey=$ { accesskey }

Any ideas on how this might be accomplished?

Thank youj

Paul

@Paul_McCauley
pulled from another example: Send Email through Service Task and MailGun (Script Based)

var data = {
    "from": execution.getVariable("fromEmail"),
    "to": execution.getVariable("email"),
    "subject": execution.getVariable("subject"),
    "text": execution.getVariable("reason")
    };

// Converts the JSON into a friendly params string
params = Object.keys(data).map(function(k) {
    return encodeURIComponent(k) + '=' + encodeURIComponent(data[k])
}).join('&')

returnedURL = url + '?' + params;
returnedURL;

Where url is your base url

This was working great on Camunda 7.5 and then I tried it on 7.6 and have run into the conector.setVariable issue and have tried the execution.setVariable as shared in this forum. I continue to get an error when trying to use the execution version instead of the connector version.

I can create many output variables and run a script for each output variable, but that seems like a lot of cut and paste and inefficient processing.

Are any of you still running into the execution/connector issue?

Thank you

Paul

@Paul_McCauley can you give more info about the error?

Can you share a sample BPMN file that recreates the issue?

Stephen,
Test 6 is an iteration/attempt using the execution.setVariable
The image represents what tasklist displays upon starting the Test 6 process
I also tried some of the outputvariable.elementname as suggested in the workaround without any success also

Test 5 is creating multiple output variables and repeating the scripts

Thank you
Paul

Hi Paul,

inside your connector script to handle the response, you need to use connector.setVariable(…) rather than execution.setVariable(…)

regards

Rob

Rob,

Thank you. However, I am confused about this. There is apparently a bug in version 7.6 that broke the connector.setVariable and was instructed in another post to use execution.setVariable.

Are you seeing a different result?
