KEYCLOAK是一套用戶、WEB API登錄管理，授權(quán)管理的WEB應(yīng)用。
如果要訪問(wèn)受KEYCLOAK保護(hù)的REST API服務(wù)，則需要夾帶一個(gè)ACCESS_TOKEN。
前端頁(yè)面：
- 前端頁(yè)面一般是給用戶使用的，則需要用戶輸入在KEYCLOAK中有效的用戶名和密碼，并提供CALL BAK的URL，提交給KEYCLOAK
http://10.80.27.69:8180/auth/realms/quickstart/protocol/openid-connect/auth?client_id=app-springboot-confidential&redirect_uri=http://10.80.27.69:8183/&response_type=code&scope=openid
- 如果KEYCLOAK驗(yàn)證通過(guò)，則通知頁(yè)面重導(dǎo)向回調(diào)的URL，并附上code=xxx，此code則是AUTHORIZATION_CODE
http://10.80.27.69:8183/?session_state=2ad9ab98-6c39-43a8-872f-2112c27b74df&code=3f48ce19-58f9-45d9-8c09-30d492bf4b24.2ad9ab98-6c39-43a8-872f-2112c27b74df.bd7526ef-b1bf-447f-baef-b7dfd6f0df93
- 回調(diào)的URL對(duì)應(yīng)的SERVELET，取得AUTHORIZATION_CODE，并加上client_id和client_secrect，調(diào)用KEYLOAK的取ACCESS_TOKEN的HTTP API，取得ACCESS_TOKEN，返回給頁(yè)面
http://10.80.27.69:8180/auth/realms/quickstart/protocol/openid-connect/token
client_id=app-springboot-confidential&client_secret=3acf7692-49cb-4c45-9943-6f3dba512dae&redirect_uri=http://10.80.27.69:8183/&grant_type=authorization_code&code=cc7ac566-90f9-404e-b88e-fa28037b07d1.591311e1-5380-46a2-9363-834f17337922.bd7526ef-b1bf-447f-baef-b7dfd6f0df93
- 頁(yè)面保存此ACCESS_TOKEN，就可以調(diào)用后臺(tái)的各種API獲取數(shù)據(jù)
