我想将我的Spring Cloud Gateway应用程序与apereo CAS服务器(在8443端口上运行)集成,并且我将CAS服务器配置为充当Oauth2授权服务器。这是流程;
i请求网关
它与授权服务器进行交互(此处为CAS)
我检查网关跟踪日志,并且在获取访问令牌步骤时发生错误。
[ctor-http-nio-2] o.s.w.s.adapter.HttpWebHandlerAdapter : [33597172] Completed 302 FOUND, headers={masked}

显然,由于请求错误,它无法请求access_token。但是,我找不到有效的参数。而且,我不手动请求,而是在后台自动发生。我的错误在哪里?感谢您的帮助。
这是我的Spring Cloud Gateway配置:
spring:
security:
oauth2:
client:
registration:
login-client:
provider: uaa
client-id: first-client
client-secret: noonewilleverguess
authorization-grant-type: authorization_code
redirect-uri: "{baseUrl}/login/oauth2/code/{registrationId}"
provider:
uaa:
authorization-uri: http://localhost:8443/cas/oauth2.0/authorize
token-uri: http://localhost:8443/cas/oauth2.0/accessToken
user-info-uri: http://localhost:8443/cas/oauth2.0/profile
prefer-token-info: false
client-authentication-scheme: form
cas oauth2注册服务
{
"@class" : "org.apereo.cas.support.oauth.services.OAuthRegisteredService",
"clientId": "first-client",
"clientSecret": "noonewilleverguess",
"serviceId": "http://localhost:8085/.*",
"name": "OAuthService",
"bypassApprovalPrompt": true,
"id": 1003,
"supportedGrantTypes": [ "java.util.HashSet", [ "authorization_code" ] ],
"supportedResponseTypes": [ "java.util.HashSet", [ "code" ] ]
}

好,问题实际上很简单。 Spring Cloud Gateway会自动填充3个字段(grant_type,代码,redirect_uri),但是cas apereo服务器具有api,该API需要5个字段(grant_type,代码,redirect_uri以及client_id,client_secret)。为了解决这个问题,您可以定义您的api,该api在cas接受3个参数,其余逻辑相同。您唯一要做的就是覆盖访问令牌api字段behaivour。
