Generic REST API changed?

Support
#1

Hello,

After I add it Generic REST API add-on in Cuba 7 I have this error in Postman (POST):

{
“error”: “unauthorized”,
“error_description”: “Bad credentials”
}

Until now, it worked. Did you make some changes?
I added these lines in webb-app.properties

cuba.rest.client.id=client
cuba.rest.client.secret={noop}secret

but is the same result (eather I make call in url or in body)

Hi,

What has changed? Have you updated the CUBA version? What is the auth header for your request?

#3

Hi,

I make this request from Postman.
Should I add in Cuba something like this:

URL myURL = new URL(serviceURL);
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();

String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

myURLConnection.setRequestProperty ("Authorization", basicAuth);
myURLConnection.setRequestMethod("POST");
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
myURLConnection.setUseCaches(false);
myURLConnection.setDoInput(true);
myURLConnection.setDoOutput(true)

?

Yes, I updated the Cuba version to 7.2.8. Should I downgrade?

#4

Did you do a major update?

As for the code - don’t add to your program. When using postman, don’t forget to specify

POST /oauth/token
Authorization: Basic {here you should use Base64Encoded cuba.rest.client.id:cuba.rest.client.secret}
Content-Type: application/x-www-form-urlencoded

as specified in documentation. And it should work.

#5

Could you be more specific please?
I have choosen Basic Authorization.
However with or without these lines is the same thing.

cuba.rest.client.id=client
cuba.rest.client.secret={noop}secret

What means these lines and what changes did you make in REST Add on?

Here is the header for the request:

And this is body

#7

How did you get Header value: c2Vzc…?

#8

It is base64-encoded string “client:secret” - ARC client (I use it instead of Postman) generates it automatically when you define authorization header

#9

Thank you! Finally works.
In order to make queries from fromtend (ReactJS) to Cuba Middleware it is necesarry authentication?
Or it is enough to use anonymousAllowed = true in the rest-services.xml method?

Please take a look here (maybe you give me a hint, please):

You need to do it only once and after that, you can use a token in order to access REST endpoints. If you use CUBA SDK and generated REST client, it should happen transparently.

As for the anonymous access, I wouldn’t recommend using it for all REST API endpoints.

#11

Can you give me an example, please?
I struggle a lot but it’s very difficult only with several code snippets.
What should I add in my code in order to run?

#12

If you have the generated ReactJS client, it should be in the sources. I guess guys from the referenced thread will help you I guess.

There is a working CUBA PetClinic Live React Demo with nice examples of various browsers and editors:
https://demo10.cuba-platform.com/petclinic-front/index.html#/

Its source code is here: GitHub - cuba-guides/cuba-petclinic-online-demo
(check for frontend module)

This sample is launched without problem on my machine.
