keycloak - 身份提供者oauth回调失败；无法找到到所请求目标的有效认证路径

Question

我正在使用 Keycloak 通过另一个代理针对 Google 对用户进行身份验证。当keycloak收到broker的回调（成功登录谷歌并回调broker后），出现如下错误：

使用身份提供者进行身份验证时出现意外错误。

在终端上，日志显示：

对可能出了什么问题有任何想法吗？

Answer 1

好像您在后端服务中使用密钥斗篷的 https 端点。由于握手失败，您的后端不信任连接。如果您没有提供任何配置，Keycloak 默认会生成一个信任库并使用其自签名证书，请在此处找到详细信息。你能做的是；

• 将您的密钥斗篷配置为使用您的密钥库和信任库
• 或继续使用您的密钥斗篷的自签名证书，但将该证书导入您的应用程序的信任库

为简单起见，我将显示第二个选项仅用于测试目的，您可以通过以下方式导出 Keycloak 的证书

• 在浏览器中转到 Keycloak 主页
• 点击安全图标
• 点击证书
• 点击详情
• 单击复制到文件

然后将其导入您的信任库，如果您的安全后端是 java，那么它就是；

keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias yourAliasName -文件路径\to\yourDownloadedCertificate.cer

重要的一点是，这里 keytool 是从你的 ${JAVA_HOME} 使用的，所以如果你的服务使用其他 JDK 版本，你应该使用 /path/to/your/jdk/keytool 来使用上面的命令。此外，如果您的密钥库不同，则默认 jvm 密钥库（在本例中为 cacerts）然后在上面的示例中也更改该密钥库
