使用REST API与KEYCLOAK进行OUATH2协议的登录认证

• 前端页面一般是给用户使用的，则需要用户输入在KEYCLOAK中有效的用户名和密码，并提供CALL BAK的URL，提交给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验证通过，则通知页面重导向回调的URL，并附上code=xxx，此code则是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
• 回调的URL对应的SERVELET，取得AUTHORIZATION_CODE，并加上client_id和client_secrect，调用KEYLOAK的取ACCESS_TOKEN的HTTP API，取得ACCESS_TOKEN，返回给页面
  
  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
• 页面保存此ACCESS_TOKEN，就可以调用后台的各种API获取数据

• 这就是authorization_code流程

• 如果是在一个API中要请求另外一个API的数据，不存在具体用户的情况
• 需提供如下参数：client_id、client_secrect和grant_type，且grant_type=client_credentials，调用KEYLOAK的取ACCESS_TOKEN的HTTP API，取得ACCESS_TOKEN
  
  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&grant_type=client_credentials
• 再将此ACCESS_TOKEN以Bearer TOKEN的方式调用别的的API
• 这就是client_credentials流程

• http://10.80.27.69:8180/auth/realms/quickstart/protocol/openid-connect/token/introspect
  client_id=app-springboot-confidential&client_secret=3acf7692-49cb-4c45-9943-6f3dba512dae
• Access Token无效时返回：
  
  {
      "active": false
  }

• 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&grant_type=refresh_token&refresh_token=asdfasd
• 返回
