Keycloak 身份代理（到 Azure AD）在授权码交换上被公司代理阻止

Question

我在Keycloak 注册了AzureAD 作为外部OIDC 提供商。 Keycloak 将客户端授权请求重定向到 AzureAD 以提供授权。 Keycloak 在公司代理后面的工作站上运行，相应的 Azure AD 托管在公共 Internet 中。我可以从本地工作站使用 Postman 连接到 Azure AD。

通过AzureAD 的授权按预期工作（提示用户输入她/他的凭据并接受同意）。授权成功后AzureAD会返回一个authorization_code到定义的Keycloakreturn-url:

http://localhost:5000/auth/realms/lsp-api/broker/ms-azure-ad/endpoint?code=AQABAAIAAADX8GCi6Js6SK82TsD2Pb7rL__pDRDcKAqDqyTeTdzmbC9n3kcz5flc0q7zDRbK-WVLUpcUU65tWSh9C-opFiwtMZOACwGLQDgh4y4ScLW-dUGN7g3Ad3_aBqK-uHPgS3uKM1OlAIeSw3NSl1DMTKhH7SGQRGITP6ARIrCL9snqNRDUbHvhfKVlLMxmJTUk0bKDIT3PzM4nBSd1NwdXc9VZ9cCFnRMjlKfpRUx3guo-58tgSL5Vsaf8TvKg8B5TSYbiDzS49epFsU0Eg_PBs1JU4Q-8vOrN_wlV1zs1IUDYbUv8EdlMdqJkaT-nBTv-4Ab2Jf3X39u4m666kvcWmezGJ-NkjPqaOSK6eglWJfjW_z9-vHFQl6F9JxdCIlGbolyZyUpo0-a0LlnVVg2gyl1wJEOSnv5RvhmTZOqa1qWxZNsyG15JeQBkcK-J0XzWmn8CaeqzsJwFlNwkpzK_XaZW-KIsWayZ0Rz2HdDYh3Mre2I4uRmDyoQLiP60lYDaYowZZ11jSBy_87vFL2alK-5sGyUajs6kODfsoSlEGHhWJeHMiC2-jYm0gMNTQIvUMYpLJRpgKX6v3n-E3Q7ZlYD_VAWOnDZBCR5iaTsUOxuXN6CiC4p01N47c4QG4Y8A9lTbVXDvVcxSBz8H7uM5DfawFGUKpSCobI9V1XKnyw1R8UXTObqmEq8gA4jBzaRZb89qAnlZ6X-w39LbLWE7MUlL0Ok8LP-7omQlVei6AdEMfrIaHNIBUFimHLgKjiqcG2ogAA&state=FevrPXHHXkICQjFEYJ_3ZyvfZ2Y9E6iM5foCcOvk5C8.jXAAgdz4mnA.lsp-api&session_state=8cb0539a-b775-4de6-b334-5cb24caeb685

此响应与状态代码 502, Bad Gateway 一起发送。此外，还会显示错误消息“使用身份提供者进行身份验证时出现意外错误”。

我已经尝试将返回的 authorization_code 手动发送到 AzureAD /token 端点，我收到了 access_token 和 id_token 回复。所以问题似乎是Keycloak 端的响应处理。

预期的行为是：

1. AzureAD 以 authorization_code 回复 Keycloak
2. Keycloak 能够将authorization_code 交换为access_token（mb。此外还有id_token）

什么不起作用：

Keycloak 无法将 authentication_code 交换为 access_token，但会抛出“使用身份提供者进行身份验证时出现意外错误”错误消息。

Keycloak 设置：

Keycloak 版本：4.1.0.Final

AzureAD Reply-URL 设置为 http://localhost:5000/auth/realms/lsp-api/broker/ms-azure-ad/endpoint。

编辑

我做了更多研究，发现这可能是公司代理问题。代理位于Keycloak（在我的机器本地主机上运行）和AzureAD 之间。那么如何设置Keycloaks Identity Brokering 的代理呢？相关Keycloak日志：

此异常意味着没有服务在您尝试连接的 IP/端口上侦听：

1. 您正在尝试连接到错误的 IP/端口。
2. 您尚未启动服务器。
3. 您的服务器没有监听连接。
4. 在 Windows 服务器上，侦听积压队列已满。

您可以尝试将 localhost 替换为您的 IP 地址。还要确保没有防火墙阻止连接。

你应该可以为JVM设置代理

-Dhttp.proxyHost=proxy.example.com -Dhttp.proxyPort=3128
