#!/usr/bin/env bash
# gh-app-token.sh —— 用 cloudbird-agent App 私钥换取 1 小时有效的安装令牌
#
# 这是 agent 与 GitHub 交互的唯一推荐认证方式:
# - 权限最小:Contents / Pull requests / Issues 读写,无 admin、无 Workflows 改动权
# - 令牌 1 小时自动过期,磁盘上不落任何长期凭据(私钥妥善保管即可)
# - 所有操作以 cloudbird-agent[bot] 身份进入审计日志,与人类账号区分
# - ruleset 照样生效:App 不能直推 main,必须走 PR 过 gate
#
# 依赖:bash curl openssl jq(无需任何 GitHub SDK)
#
# 用法:
# export CB_APP_ID=123456 # App 详情页的 App ID
# export CB_APP_KEY_FILE=~/.config/cloudbird/cloudbird-agent.pem
# # CI / secret 场景改用字面量: export CB_APP_KEY="<PEM 全文>"
#
# GH_TOKEN=$(bash gh-app-token.sh) # 作用域=安装的全部仓库
# GH_TOKEN=$(REPO=template-service bash gh-app-token.sh) # 作用域=单仓库(推荐)
# gh api user # 验证:应显示 cloudbird-agent[bot]

🌐 Web query:

GitHub REST API GET /orgs/{org}/installation authenticated as GitHub App JWT response installation id pagination /app/installations

💡 Result:

To retrieve an organization's installation ID while authenticated as a GitHub App using a JSON Web Token (JWT), you use the GET /orgs/{org}/installation endpoint [1][2]. Authentication Process: 1. Generate a JWT using your GitHub App's private key and App ID [3][4]. 2. Include the JWT in the Authorization header of your request as a Bearer token: Authorization: Bearer YOUR_JWT [3][4]. 3. Call the endpoint: GET /orgs/{org}/installation [1][2]. The response will be a JSON object containing the installation details, including the installation id (found under the id key) [5]. Regarding Pagination: - The GET /orgs/{org}/installation endpoint returns a single installation object for the specified organization, so it does not require pagination [1]. - In contrast, the GET /app/installations endpoint, which lists all installations for your authenticated app, does support pagination [6][7]. This endpoint accepts per_page and page query parameters (default per_page is 30, max 100) and provides paginated results [8][9]. You can use the Link header in the response to fetch additional pages or use the GitHub Octokit SDK's built-in pagination methods [10].

改用组织 Installation 查询端点。

/app/installations?per_page=100 只读取第一页。目标组织不在第一页时,脚本会找不到 INSTALL_ID 并退出。改用 GET /orgs/{org}/installation 直接查询目标组织的 Installation。

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

默认要求 REPO。严重级别:高。

REPO 为空时,BODY='{}' 会创建可访问 installation 全部仓库的写入令牌。该令牌可写入 manifest 授权的每个仓库。GitHub 仅在请求指定 repositoriesrepository_ids 时才限制令牌仓库范围。(docs.github.com)

默认拒绝空 REPO。如果确实需要全仓库令牌,要求调用方显式设置确认变量。

建议修改
+if [[ -z "${REPO:-}" && "${ALLOW_ALL_REPOSITORIES:-}" != "1" ]]; then
+  echo "错误:需要 REPO。全仓库令牌请显式设置 ALLOW_ALL_REPOSITORIES=1" >&2
+  exit 1
+fi
+
 BODY='{}'
 [[ -n "${REPO:-}" ]] && BODY=$(jq -nc --arg r "$REPO" '{repositories: [$r]}')

同时更新 Line 17 的用法说明,避免将全仓库令牌作为默认调用方式。

为所有 GitHub API 调用设置连接和总超时。

scripts/gh-app-token.sh 中的两个 curl 调用均未设置 --connect-timeout--max-time。网络请求停滞时,认证流程可能无限等待。请为 gh_api 和创建安装令牌的调用统一添加超时参数。
