Oracle SOA - Invoking a service with x-form-urlencoded

Need your help!

Goal: Invoke an API that will generate a token with body type as x-form-urlencoded.

Result: 400-Bad request

What we done so far is the ff:

  1. Indicate in the invoke property (to) that Content-Type : apppication/x-form-urlencoded.
  2. Assign the value of grant_type and assertion in a variable like below.

grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer&assertion=eyJhbGciOiJSUzI1NiJ9.eyJpc3MiOiAiM01WRzlMekt4YTQzenFkSWR4TGJaRVlQOUFnMzNOS0FGcVJ6aDdRM21hTWRJSjAwVmxMakI4bE5oaFRMN0M1Tm1OT0M4eUN6c1F1RUdEbVlVcTVzVyIsICJzdWIiOiAisdasdbi5sb3JlbnpvQGhvZWdoLmNvbS5zb2FhdXRoIiwgImF1ZCI6ICJodHRwczovL3Rlc3Quc2FsZXNmb3JjZS5jb20iLCAiZXhwIjogIjE2Mjk5NDQwMDcifQ.JiAEVW0sP96If24-oYTiCVMK8oyDlo_xfT4Yei44AYAwH0trfRtJCDZOsuDdOLkdAz0kRValqrPcOuPzPIfyWtrSAHU0bUWwmAc9XK5pV4MLgfKuZ_AfkLSygdu0Z9Tk9eG4WYyj953STNY316vTXQwa_uWG

  1. In the trace. & is converted to '&' not sure if this is the issue here. We are sure that the assertion key is valid tried it by postman/soapui to call the api.

  1. Additionally, we also tried wrapping the grant type and assertion in cdata using toCdata of oracle but no luck!!! argh!

Anyyyy suggestions/recommendation?

Solution

  • Solution:

    1. In the reference swim lane, ensure that in request payload the url-encoded is selected. add grant_type, and assertion as query param.
    2. In the bpel, invoke > property tab, select rest.query.grant_type value is urn:ietf:params:oauth:grant-type:jwt-bearer . do the same process in assertion.
