Hello,

we have to connect to a Webservice with an OAuth 1.0 Authentication.

We can receive the consumer-token, but we are not able to get the correct request token.
We always receive an "HTTP/1.1 401 Unauthorized" Error.

Has someone already succeeded an OAuth 1 Authentication with Genero Webservice?

Any help is welcome.

Stefan

Hello Stefan,

Our Documentation and Examples are all naming 'OAuth2' (mainly because it is referring to Google Services). Do you have test credentials so you can share a basic sample?
I would recommend you contact your local Four Js support center while you're waiting for some feedback from the community

Best

Hello Laurent,

attached our testprogram.

I think our Problem is in generating the signature.

We have to build a signature with HMAC-SHA1 (https://tools.ietf.org/html/rfc5849#section-3.4.2)
This should be done like this: digest = HMAC-SHA1 (key, text)

In the Genero-Docu we found the function “security.Digest.CreateDigestString”
This function requires a Base-64 String as Input.
We think that this can be the Problem.


Before you start the program, you have to add the following lines to the fglprofile:


ws.discovergy.url = "https://api.discovergy.com/public/v1/oauth1/consumer_token"
ws.discovergy.verifyserver = "FALSE"

ws.discovergy1.url = "https://api.discovergy.com/public/v1/oauth1/request_token"
ws.discovergy1.verifyserver = "FALSE"

Hi,

Just to let you know that we provided Stephan with a sample.
Indeed, to build the signature there are specifications/conventions you need to comply to.

It is not a complete implementation of OAuth 1.0.
There are 2 main functions
- DoAuth1Request: to do the OAuth request with the signature
- ParseOAuth1RequestTokenResponse: to get the OAuth response

Find attached an excerpt of the sample.

Best regards,
Sisa.
