Hi Guys,

I am trying to test some microservices and first I need to get new token from the Keycloak server and when I am trying to run the below “keyword” I am getting the error: “No resource method found for GET, return 405 with Allow header”, but I don’t have any GET method on my keyword.

A valid token for "${client}" with secret "${client_secret}"
    ${auth} =    Create List    ${client}    ${client_secret}
    ${headers_dict} =    Create Dictionary    Content-Type=application/x-www-form-urlencoded    Accept=application/json
    ${data_dict} =    Create Dictionary    grant_type=client_credentials
    Create Session    req    http://keycloak.${domain}    auth=${auth}
    ${resp}=    POST On Session    req    /auth/realms/gdp/protocol/openid-connect/token    headers=${headers_dict}    data=${data_dict}
    Should Be Equal As Strings    ${resp.status_code}    200
    ${token}=    catenate    Bearer    ${resp.json()}[access_token]
    Set Suite Variable    ${EX_TOKEN}    ${token}
    Log    ${EX_TOKEN}

output.log result:

You are trying to get authenticated session with a token to work over HTTP (not encrypted) and backend tells you you thats not allowed - i wonder why :smiley:

Maybe change the url to HTTPS (encrypted) where you create the session ?

Reason for GET most likely could be that the response to POST will also return a redirect header that requests library will obey .
