如何配置密钥斗篷以保护URL上托管的所有服务

I have multiple services running on localhost:8080. For e.g:

a) GET localhost:8080/idtest/{id}

b) POST localhost:8080/idtest

and to test them I use POSTMAN.

I want to protect these services by keycloak authentication when they are triggered. Hence, I got the keycloak server installed, created realm,client and rolemapping.

Is there a possibility to add authentication in general to all API's with the same root path just at one place?

Using Golang for implementation.

In keycloak client page:

Base URL: localhost:8080

Redirect URL: localhost:8080/test

I have followed this procedure in my localhost client.

As per it, when I am running localhost:8080 on my browser, I get redirected to http://localhost:8080/test and I get below json:

  {
    "OAuth2Token": {

    "access_token": "eyJhbGciOiJSUzI1Ni",
    "token_type": "bearer",
    "refresh_token": "eyJhbGciOiJIUzI1NiIs",
    "expiry": "2019-07-16T17:41:43.4884786-04:00"

    },
    "IDTokenClaims": null
  }

Now when I am using POSTMAN with my header type authorization - bearer "accesstoken retrived from above JSON" for

1) http://localhost:8080 I again get HTML for keyclaok login, but when I am using browser to hit http://localhost:8080 it is redirecting me to localhost:8080/test page.

How can I test it from POSTMAN? What am I doing wrong?

2) http://localhost:8080/idtest/12345 this service runs seamless irrespective of access token. I want to know how can I add this under the umbrella of same authentication ? I read about single sign on for multiple clients but these services belong to same client.

I tried adding them as resources under authorization tab of client. Do I need to make any changes in the code as well ? How can I do it ?
