//! 微软轨:device-code 全流程 + 会话/刷新语义(`PlanDoc/07-accounts.md` §1、`analyse/04` §4–§5)。
|
||||
//!
|
||||
//! 分四块,各管一件事:
|
||||
//! - [`session`]:`MicrosoftSession`(凭据载荷)与**刷新判定**(纯函数,可脱离网络单测);
|
||||
//! - [`endpoints`]:端点表(生产 = 微软消费版直连;测试 = 整表指向 mock);
|
||||
//! - [`flow`]:device-code 发起 / 轮询 / refresh(OAuth 层);
|
||||
//! - [`chain`]:XBL → XSTS → login_with_xbox → entitlements → profile(Xbox/MC 层)。
|
||||
//!
|
||||
//! # client id 从哪来
|
||||
//!
|
||||
//! device-code 流必须带一个**已在 Azure 注册的公共客户端 id**。HMCL 把它烘进 jar 的
|
||||
//! manifest(`hmcl.microsoft.auth.id`),我们同理:二进制里不硬编码,改由
|
||||
//! `ULL_MSA_CLIENT_ID`(运行期)或构建期 `option_env!` 提供。没有配时
|
||||
//! [`MicrosoftAuth::from_env`] 返回 [`AuthError::Unsupported`] 并说清要配什么——
|
||||
//! 这比编一个假 id 让用户看到 `invalid_client` 诚实。
