Gatling Создать токен OAuth2.0 с использованием обратного вызова URL не работает

Question

Вот мой сценарий.

val header = Map(
    "Accept" -> """application/json""", 
    "Content-Type" -> """application/x-www-form-urlencoded, charset=UTF-8""") 

val auth_token = scenario("POST Authentication") 
     .exec(
      http("POST OAuth Req") 
      .post("/validate/activationURL") 
      .formParam("oauth.token.client.secret", "*******") 
      .formParam("oauth.token.url", "https://myweb.com/as/token.oauth2") 
      .formParam("oauth.token.client.id", "my-test-user") 
      .formParam("oauth.token.grant.type", "client_credentials") 
      .formParam("oauth.token.scope", "my:test:activation") 
      .headers(header) 
    ) 

Но я получаю ошибку, как

========================= 
HTTP request:

headers= 
Accept: application/json 
Content-Type: application/x-www-form-urlencoded

Наконец, я полагаю, это, это answere помог мне здесь https://stackoverflow.com/a/41273020/1665592

То, что я изменился,

Заголовки

Да, заголовок так важны.

val header = Map(
    "Content-Type" -> """application/x-www-form-urlencoded""") 

Этих переменных имена OAuth 2.0 стандарты client_secret, client_id, grant_type, scope в то время как я пытался oauth.token.client.secret

val auth_token = scenario("POST Authentication") 
     .exec(
      http("POST OAuth Req") 
      .post("https://myweb.com/as/token.oauth2") 
      .formParam("client_secret", "*******") 
      .formParam("client_id", "my-test-user") 
      .formParam("grant_type", "client_credentials") 
      .formParam("scope", "my:test:activation") 
      .headers(header) 
      .check(status.is(200)).check(jsonPath("$.access_token").exists.saveAs("access_token")
