fix(assistant): 关联 id 统一走安全上下文兜底，修 test_model 在非安全上下文下不可用 by SwrodKing · Pull Request #568 · aimod-cc/Agent2API

SwrodKing · 2026-11-11T12:46:56Z

内置助手的 test_model 工具裸调 crypto.randomUUID()。该 API 只在安全上下文（HTTPS / localhost / WebView2）可用；面板经反代以普通 HTTP + 非 localhost 地址打开时（内网 IP、自建域名），它是 undefined，裸调抛 TypeError，整只工具直接报错，一条请求都发不出去。

同一个面板里的「测试」对话框（model-test-dialog.tsx）早就用自拼 UUID 兜底了 —— 于是出现两条路径行为不一致：对话框能测，助手工具不能测。

复现

用反代把面板挂在 http://<内网IP>:<端口>（非 localhost、非 HTTPS）
打开内置助手，让它调用 test_model
报错（crypto.randomUUID is not a function），工具完全不可用

同一环境下 generate_images 正常 —— 因为它不需要生成随机 UUID。

改动

新增 ui-shared/correlation-id.ts，把兜底收敛到一处：

newCorrelationId() // 优先 globalThis.crypto?.randomUUID?.()，退化到形态合法的 v4

退化实现拼的是形态合法的 v4（第 3 组以 4 开头、第 4 组以 a 开头），不是任意随机串 —— 上游若按 UUID 格式校验也能过。

随后把散落的裸调用收编到它（共 12 处 → 0 处）：

文件	位置
`ui-islands/src/islands/assistant-tools.ts`	`test_model` —— 本次故障点
`mobile/src/lib/assistantTools.ts`	`test_model`（手机端同款）
`ui-islands/src/islands/model-test-dialog.tsx`	删除本地 `newTestId()`，改用共享函数
`ui-islands/src/islands/agent-model-fields.tsx`	行 key（2 处）
`ui-islands/src/islands/agent-model.ts`	profile id
`mobile/src/pages/AssistantPage.tsx`	会话 / 消息 / 轮次 id（5 处）
`mobile/src/api/assistant.ts`	会话 fork id

routing-group-form.tsx 的 newRouteId() 与 assistant-state.ts 的 newSessionId() 本就有各自的兜底（形态不同但功能正确），本次不动，避免扩大改动面。

影响面

纯前端 id 生成。安全上下文中行为完全不变（仍走 randomUUID）；只在原来必然抛错的非安全上下文里，从「崩溃」变成「可用」。

useRef<string>(crypto.randomUUID()) → useRef<string>(newCorrelationId()) 是 1:1 行为替换：原本就是每次渲染求值后丢弃，改动不改变这一点。

验证

全仓库裸 crypto.randomUUID() 调用：12 处 → 0 处（余下 2 处均自带兜底）
7 个文件的 import 路径逐个解析确认可落地；新文件零依赖，不引入循环
兜底逻辑独立验证：10000 次生成形态 100% 合规，20000 次无重复
tsc --noEmit 对比基线（两处子项目均逐条比对）：
- ui-islands：基线 316 → 改动后 316
- mobile：基线 139 → 改动后 139
- 零新增类型错误；本次改动的文件在过滤后均无新增报错

Summary

1. 📌 通俗总结（这个 PR 做了什么？）

这个 PR 统一了桌面端和移动端的关联 ID 生成方式。

新增共享方法 newCorrelationId()。
优先使用 globalThis.crypto?.randomUUID?.()。
不支持时生成 v4 形态的备用 ID。
替换 7 个文件中的直接 crypto.randomUUID() 调用。
覆盖会话、消息、模型配置和模型测试等场景。

这样可以避免面板通过非 localhost 的普通 HTTP 地址打开时，因 crypto.randomUUID() 不可用而导致模型测试工具无法发送请求。

2. 💡 产品与技术方案评估

这是合理的兼容性修复。它直接解决特定部署环境下的功能中断，不需要用户调整浏览器或部署方式。

技术方案整体清晰：

统一生成逻辑，避免桌面端、移动端和模型测试对话框各自实现。
在安全上下文中继续使用原生 UUID。
备用 ID 保留 UUID v4 的格式，可继续用于请求关联和取消请求。

需要注意以下问题：

备用实现使用 Math.random()，不具备加密安全性。该 ID 不能用于认证、授权或安全令牌。
备用 ID 是 v4 形态，但实现只固定了变体位 a。如果上游严格按 UUID 标准校验，建议增加单元测试确认兼容性。
当前改动未增加测试文件。建议补充对 crypto.randomUUID() 可用和不可用两种环境的测试，并验证 test_model 的请求与取消流程。
现有验证报告对 tsc --noEmit 是否实际执行存在冲突，因此编译结果暂不能确认。

新增共享的 newCorrelationId()，并将手机端和 UI islands 中多个会话、消息、模型及测试关联 ID 的生成方式改为调用该函数。

Changes: 关联 ID 生成

Layer / File(s)	Summary
共享关联 ID 生成器 `desktop-tauri/ui-shared/correlation-id.ts`	新增 `newCorrelationId()`。该函数优先调用 `crypto.randomUUID()`；当 API 不可用或返回假值时，生成 UUID 形态的随机字符串。
手机端 ID 生成调用 `desktop-tauri/mobile/src/api/assistant.ts`, `desktop-tauri/mobile/src/lib/assistantTools.ts`, `desktop-tauri/mobile/src/pages/AssistantPage.tsx`	分叉会话、模型测试、会话和消息 ID 改为通过共享生成器生成。
UI islands ID 生成调用 `desktop-tauri/ui-islands/src/islands/agent-model-fields.tsx`, `desktop-tauri/ui-islands/src/islands/agent-model.ts`, `desktop-tauri/ui-islands/src/islands/assistant-tools.ts`, `desktop-tauri/ui-islands/src/islands/model-test-dialog.tsx`	模型行、方案和模型测试关联 ID 改为通过共享生成器生成。模型测试对话框移除本地 ID 生成函数。

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Suggested reviewers: aimod-cc

Merge Risk: Moderate · up to 7ad92

The shipped UI still runs the old code, so the test_model failure over plain HTTP is not fixed, and the artifact consistency check is likely to fail for PRs targeting main or beta. Rebuild the UI islands and mobile bundles and commit them, including the updated sw.js, before merging.

Security architecture risk: Low · up to 7ad92

The change enables previously failing operations without changing their existing access checks or persistence sequencing. No new authorization bypass was established. The non-cryptographic fallback now also generates persistent conversation identifiers, whose behavior across supported environments is not fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The traced impact is client identifier creation and its existing gateway consumers: saved conversations, message selection, model-test records, and in-flight cancellation. The comparison does not change server credentials, privileges, network policy, or deployment configuration. Deployment-specific identity and tenant assumptions were not supplied.

Security Findings and Attack Paths

inferred — The non-cryptographic fallback alone does not establish a new unauthorized-cancellation attack path. Request listing and termination use the same management admission checks, and admitted callers can obtain request identifiers without predicting them. The supplied rejected cryptography candidate is therefore not retained as an introduced concern; its incomplete verification-context receipt remains a coverage limitation.

Trust Boundaries and Controls

observed — Model tests independently require a usable selected API key and enforce model and provider scope. Restricted keys without an administrator session cannot access management-only routes such as request termination. Management admission also retains its existing deployment-dependent local and compatibility branches; this PR does not strengthen or weaken those branches.

Resilience and Maintainability Implications

observed — Existing model-test recovery controls remain: dialog cancellation invalidates stale callbacks, tool abort listeners are removed in finally blocks, and server completion or handler interruption unregisters cancellation tokens. Duplicate identifiers still encounter existing ID-keyed registry and session-upsert behavior; practical fallback collision or prediction exposure was not established.

Hardening Proposals

proposed — Consider preferring crypto.getRandomValues when randomUUID is unavailable, where supported, and documenting that these identifiers are not authorization credentials. This would preserve stronger randomness for persistent identifiers without treating the current fallback as a verified vulnerability.

重新构建并提交前端产物

本次提交只改了源码，没有更新 ui/islands/ui.js 和 ui/m/mobile.js。桌面端、服务端和 PWA 直接使用入库的静态产物，因此用户仍会运行旧代码，HTTP 下的 test_model 修复不会生效。(github.com)

请重建并提交两端产物及更新后的 ui/sw.js。否则，即使类型检查通过，产物一致性检查也会失败。(raw.githubusercontent.com)
