CAS单点登录：开启OIDC协议（八）

1.引入依赖

<dependency>
  <groupId>org.apereo.cas</groupId>
  <artifactId>cas-server-support-oidc</artifactId>
  <version>${cas.version}</version>
</dependency>

2.生成jwks

官方提供的用于生产JWK文件工具：https://mkjwk.org/

复制出来如下：

        {
            "p": "-8Jzd4q1UBRcAYsHbgsJzODtZQWuoIQhZ-PphuyUaQVQXTF466FZjeKkvlGkf3H-TgxlQxgb5S0rfbNKxlR3NO4xdGwtuv8hvzI1FJFmCA2Ap78u0-9UCvmpmiJ--SREF6r50_-kXOg_RIvEmH_mEVjHWMN7k4ajwL5jnWr1R0M",

            "qi": "WUYT1z4nJ6pI3KS5SjWneZf-RAioAvh-d2k-y2tKpgQOSQX_E-n8YqAxVBZrbXRt5mcM4Tr39E65jmQQKkIbxylOyzh0yffnSjLpsi1vZa1ZoTtO2ae2hlk9NvCHjKi0xd4K-A_v93VUZERIV_A2ZeMMfw7u0waLvgJCWn90DmU",

        }
    ]
}

在static下新建keystore.jwks文件，将以上内容复制进去。

3.修改application.properties

##
# OIDC
#
#签名文件路径
cas.authn.oidc.jwksFile=classpath:/static/keystore.jwks
#签发端地址
cas.authn.oidc.issuer=${cas.server.name}/oidc/
#-------------------开启动态注册客户端------------------
cas.authn.oidc.dynamicClientRegistrationMode=OPEN
#-------------------自定义字段------------------
cas.authn.oidc.userDefinedScopes.hbtvprofiles=id,name,mobile,email,avatar

4.在service下新建OIDC-1002.json

{
  "@class" : "org.apereo.cas.services.OidcRegisteredService",
  "clientId": "abcd",
  "clientSecret": "xyz",
  "serviceId" : "^(https|http|imaps)://app1.cas.com.*",
  "name": "ODICService",
  "id": 1002,
  "scopes" : [ "java.util.HashSet",
    [ "profile", "email", "address", "phone", "offline_access", "displayName", "eduPerson" ]
  ]
}

5.OIDC所有节点信息

6.测试

请求：https://server.cas.com:8443/cas/oidc/.well-known，可以如下信息：

{
    "issuer":"https://server.cas.com:8443/cas/oidc/",
    "scopes_supported":[
        "openid",
        "profile",
        "email",
        "address",
        "phone",
        "offline_access"
    ],
    "response_types_supported":[
        "code",
        "token",
        "id_token token"
    ],
    "subject_types_supported":[
        "public",
        "pairwise"
    ],
    "claim_types_supported":[
        "normal"
    ],
    "claims_supported":[
        "sub",
        "name",
        "preferred_username",
        "family_name",
        "given_name",
        "middle_name",
        "given_name",
        "profile",
        "picture",
        "nickname",
        "website",
        "zoneinfo",
        "locale",
        "updated_at",
        "birthdate",
        "email",
        "email_verified",
        "phone_number",
        "phone_number_verified",
        "address",
        "gender"
    ],
    "grant_types_supported":[
        "authorization_code",
        "password",
        "client_credentials",
        "refresh_token"
    ],
    "id_token_signing_alg_values_supported":[
        "none",
        "RS256"
    ],
    "introspection_endpoint_auth_methods_supported":[
        "client_secret_basic"
    ],
    "jwks_uri":"https://server.cas.com:8443/cas/oidc/jwks",
    "token_endpoint":"https://server.cas.com:8443/cas/oidc/accessToken",
    "authorization_endpoint":"https://server.cas.com:8443/cas/oidc/authorize",
    "userinfo_endpoint":"https://server.cas.com:8443/cas/oidc/profile",
    "registration_endpoint":"https://server.cas.com:8443/cas/oidc/register",
    "end_session_endpoint":"https://server.cas.com:8443/cas/logout",
    "introspection_endpoint":"https://server.cas.com:8443/cas/oidc/introspect",
    "revocation_endpoint":"https://server.cas.com:8443/cas/oidc/revoke"
}

从response_types_supported，可知相较于OAuth模式，OIDC多了一种id_token。

6.1.id_token模式

1.请求以下地址获取id_token：

　　https://server.cas.com:8443/cas/oidc/authorize?response_type=id_token token&scope=openid&client_id=abcd&redirect_uri=http://app1.cas.com

　　response_type：获取的响应类型，id_token token，中间有空格

返回如下：

http://app1.cas.com/#access_token=AT-2-C3bFdo7yBqgR0-kfQZn2GTT54BDE-k8I&token_type=bearer&expires_in=28800&refresh_token=RT-2-XRmagsTk9HsVfty-uOo-ffT-mM0bwuWH&id_token=eyJhbGciOiJSUzI1NiIsImtpZCI6ImNhcyJ9.eyJqdGkiOiJUR1QtMS14V1pYUlgwNEpUazdWT3BVQlpGajk2MFBSeGJPT2VpVVRDLWhnSzg1cUdxZm13T3lDLXNHVTV2R3hSRlFYWE1OUnlNYW5nZWwtUEMiLCJpc3MiOiJodHRwczovL3NlcnZlci5jYXMuY29tOjg0NDMvY2FzL29pZGMvIiwiYXVkIjoiYWJjZCIsImV4cCI6MTU5MDQzNTA3NSwiaWF0IjoxNTkwNDA2Mjc1LCJuYmYiOjE1OTA0MDU5NzUsInN1YiI6ImFkbWluIiwiYW1yIjpbIlJlbWVtYmVyTWVVc2VybmFtZVBhc3N3b3JkQ2FwdGNoYUF1dGhlbnRpY2F0aW9uSGFuZGxlciJdLCJzdGF0ZSI6IiIsIm5vbmNlIjoiIiwiYXRfaGFzaCI6IjZ0bkgyejk5SUQ4ZkVIWmhnSHI5aFEiLCJwcmVmZXJyZWRfdXNlcm5hbWUiOiJhZG1pbiJ9.brHP9rswVSNFWLorJnAlGqkU7xrPa9CxR255d8VKJjJMqfjRcDxVKjEGQgztSR-upX2PNFqLG7PZMi1mWbZ86NV_4f3wQ9ywQiB59wE4Qe5W_v0kgEz5wF9gi9oWLExKI9sj2EPeU7L-AKVPz-5oRGl20Vs8_bJOqJaPnBVz1jojTsdBgPW4EcEiKv8tU6FA7KXuC_61kXVCCBj8vCLDIOWZETep8KFN_3tLfJ5CcmzC3MioG7Jmg60YhstsS9W2HZV_faxQFV44HgxnuWV-G4wp4_bhs6GorJqCQCNKjE2r1ZFC6bm3jRHQvRWvDDIoyk79HBrQW-noKk5NA8N_wg

整理如下：

access_token：AT-2-C3bFdo7yBqgR0-kfQZn2GTT54BDE-k8I

refresh_token：RT-2-XRmagsTk9HsVfty-uOo-ffT-mM0bwuWH

2.根据accessToken获取用户信息，请求如下：

　　https://server.cas.com:8443/cas/oidc/profile?access_token=AT-2-C3bFdo7yBqgR0-kfQZn2GTT54BDE-k8I

得到响应如下：

{
  "sub" : "admin",
  "auth_time" : 1590406275,
  "attributes" : {
    "credentialType" : "RememberMeUsernamePasswordCaptchaCredential"
  },
  "id" : "admin"
}
