尝试使用 OAuth2RestTemplate 访问 oAuth2 令牌时,我需要有关错误的帮助
下面提供了我的 java 代码。
我正在使用 Spring 4.3.4 版和 Spring Security oAuth 2.3.4 版
谢谢!
ClientCredentialsResourceDetails returnValue = new ClientCredentialsResourceDetails();
returnValue.setAccessTokenUri(xxx);
returnValue.setClientId(yyy);
returnValue.setGrantType("client_credentials");
returnValue.setClientSecret(zzz);
AccessTokenRequest atr = new DefaultAccessTokenRequest();
OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(returnValue , new DefaultOAuth2ClientContext(atr));
restTemplate.setRequestFactory(getClientHttpRequestFactory());
logger.debug(restTemplate.getAccessToken());
当我创建一个 JUnit 测试类并运行它时,我得到以下错误跟踪。oAuth2 REST API 使用 SOAP UI 工作。
error="access_denied", error_description="Error requesting access token."
