Keycloak: curl で access_token を取得

get_access_token.sh

#
curl -X POST http://localhost:8080/realms/myrealm/protocol/openid-connect/token \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=password" \
  -d "client_id=myclient01" \
  -d "client_secret=U7NTfODXUhLd4K9JwAVYpTvX6ghlRIu6" \
  -d "username=scott" \
  -d "password=hello9" > access_token.json

実行

./get_access_token.sh

パスワードが違った時の実行結果

{"error":"invalid_grant","error_description":"Invalid user credentials"}

Httpie を使った場合

go_httpie.sh

URL="http://localhost:8080/realms/myrealm/protocol/openid-connect/token"
#
http --form POST $URL \
	"grant_type=password" \
	"client_id=myclient01" \
	"client_secret=U7NTfODXUhLd4K9JwAVYpTvX6ghlRIu6" \
	"username=scott" \
	"password=hello9" > access_token.json
