WSo2 APIM 在尝试生成密钥时出现错误 401

如何解决WSo2 APIM 在尝试生成密钥时出现错误 401

当我尝试在 WSO2 API 管理器中为创建的应用程序生成密钥时出现以下错误，不知道为什么或如何解决这个问题。我在与网关和 KM 节点不同的实例上运行 WSO2 AM，到目前为止，其他一切似乎都很好，只是当我尝试通过密钥生成向导或手动生成它们时出错：

解决方法

根据共享的跟踪记录，API 管理器无法通过 (401) 密钥管理器组件进行身份验证以注册客户端。

这可能是由于 TOML 配置中的用户名和密码配置错误所致。如果您更改了超级管理员凭据，请务必使用您环境中的正确凭据集更新以下配置

[apim.key_manager]
username = "superadmin-username"
password = "superadmin-password"

要么使用正确的凭据集更新上述配置，要么对 username 和 password 配置进行评论，以使用默认映射自行选择超级管理员凭据（因为您拥有与 Devportal 位于同一节点中的密钥管理器）。

请尝试建议的方法并告诉我们
