无法在 Kubernetes 设置中的 WSO2 API Manager 3.2.0 中找到请求目标错误的有效证书路径
unable to find valid certification path to requested target error in WSO2 API Manager 3.2.0 in Kubernetes setup
我们已经部署了 WSO2 API manager-3.2.0 并作为 Keymanager 与 Identity Server-5.10.0 集成。
我们正在 API 管理器中添加域证书，以使用以下步骤与 Identity Server-5.10.0 通信：
- 在路径中添加域证书：
/repository/resources/security 用于 IS 和 API 管理器
- 将证书的 public 密钥添加到 IS 和 API 管理器的
client-truststore.jks 文件中
- 在
/repository/confs/deployment.toml 文件中为 IS 和 APIM 添加以下配置
**[keystore.primary]**
file_name = "wso2carbon.jks"
type = "JKS"
password = "wso2carbon"
alias = "wso2carbon"
key_password = "wso2carbon"
**[keystore.tls]**
file_name = "domain.jks"
type = "JKS"
password = "cert_pwd"
alias = "domain_alias"
key_password = "cert_pwd"
添加以上配置后，我们在 API 管理器日志中出现以下错误：
