Consuming a webservice with headers

RLOMASKY

I'd like to consume a webservice from Aware. I don't need to process the output, just call it. I have a couple of headers to send along. I've found a lot on this forum about how to publish a webservice, not not how to consume it. Please point me in the right direction. I've seen mentions of plug-ins. Any examples of those?

Thanks,
Rachel

Rachel, you should join your dad in the upcoming conference. It's a new up coming feature that will be showcased there.

In other words, it's not possible now?

I can not answer that question with 100% conviction. But Vlad will be covering a session on this new feature for V8.1

Are you trying to make two AwareIM programs "talk" to each other, Rachel?

RLOMASKY

No, I'm trying to make an Aware program trigger something in an external (nothing to do with Aware) API. I used to do with a DISPLAY URL: DISPLAY URL 'https://api.mycompany.com/import/' + AS_STRING(BO.EXT_id, '####')

But now it needs authentication, with a couple of simple JSON headers, so I need to be able to pass those as well.

Sorry I can't help you with that, Rachel.

Rachel,

If you have access to a server with php loaded on it:
Create a php program to call the web service
Inside Aware use DISPLAY URL to call your php program.

Hi Rachel,

My understanding is that until v8.1 arrives the best way to do this is through development of a Java plugin. I don’t know how to write Java so as an interim I’ve developed a technique to consume REST services that uses Python scripts. I gave an example at https://forum.awareim.com/d/9717/2&hilit=Python#p43966.

There are heaps of examples on the web of Python scripts interacting with web services with minimal code. Anyway my basic scheme is :

Outside of AwareIM develop a hard coded Python script that achieves your requirment and reports its results in the form of a AwareIM import friendly CSV file.
Convert that script into an AwareIM document template that uses <<Object.Attribute>> tokens to inject variable data into the script
Write a process that does the following :
Exports the Python document template onto your server
Executes that Python script
Imports the CSV file output by the Python

The beauty of Python is it has lots of simple ways to deal with things like parsing JSON and XML, constructing headers for REST requests, construct text files etc. And it’s relatively easy to code. I’ve used it to Geocode addresses and interact with web services that send SMS messages.

Looking forward to the conference in Providence 😃

Actually, I showed Rachel how to do it. Its is fairly simple AS LONG as you do not need custom headers. (I was able to handle cross-domain issues on the server).

How did you accomplish it, Bruce?

Is this discussion about consuming a SOAP web service or REST web service?

Consuming a REST service is only fully supported in the upcoming 8.1 version (where you will be able to explicitly specify the headers of the request).

In 8.0 you need a Java plugin for this.

Rachel did NOT need any results sent back, so this works:
EXEC_SCRIPT $.ajax({ type: 'POST', url: 'http://localhost:3301/printOrderAck', contentType: 'application/json', data: JSON.stringify({ option : 'email', orderNo : + LoggedInRegularUser.lastOrderNumber + , outputFile : 'orderAck.pdf', email : 'bruce@bruceL.com' }), dataType: 'text', success: function( response ){ console.log( response); }, error: function( error ){ // Log any error. console.error( 'ERROR:', error ); }, });
