3.7. OAuth API 事件故障排除

在有些情况下，API 服务器会返回一个 unexpected condition 错误消息；若不直接访问 API 主日志，很难对此消息进行调试。该错误的基本原因被有意遮挡，以避免向未经身份验证的用户提供有关服务器状态的信息。

这些错误的子集与服务帐户 OAuth 配置问题有关。这些问题在非管理员用户可查看的事件中捕获。OAuth 期间遇到 unexpected condition 服务器错误时，可运行 oc get events 在 ServiceAccount 下查看这些事件。

以下示例警告缺少正确 OAuth 重定向 URI 的服务帐户：

$ oc get events | grep ServiceAccount

1m         1m          1         proxy                    ServiceAccount                                  Warning   NoSAOAuthRedirectURIs   service-account-oauth-client-getter   system:serviceaccount:myproject:proxy has no redirectURIs; set serviceaccounts.openshift.io/oauth-redirecturi.<some-value>=<redirect> or create a dynamic URI using serviceaccounts.openshift.io/oauth-redirectreference.<some-value>=<reference>

运行 oc describe sa/<service_account_name> 可以报告与给定服务帐户名称关联的任何 OAuth 事件。

$ oc describe sa/proxy | grep -A5 Events
