OpenAI GitHub Actions 身份联合配置
2026-11-09 15:42 更新
通过 GitHub Actions 签发的 OIDC 令牌换取短期 OpenAI 访问令牌，使工作流无须在 GitHub secrets 保存长期 API 密钥。具有 id-token: write 且主动请求身份令牌的 job 可获得 GitHub 签名 JWT；OpenAI 验证 issuer、audience、签名和映射属性后签发访问令牌。
设置 GitHub Actions
为工作流或 job 授予令牌请求权限：
来源示例 1（yaml）：
## [中文] 按本节配置受众、工作负载身份和令牌挂载；受众必须与OpenAI提供商一致，生产环境须限定账户及权限。
permissions:
id-token: write
contents: read
id-token: write 不赋予仓库内容写权限；contents: read 用于 actions/checkout。请求 audience 必须与 OpenAI 提供商完全一致。自定义 JS action 可调用 core.getIDToken("your-wif-audience")；Shell 可直接调用 GitHub OIDC 请求 URL。https://api.openai.com/v1 等含保留字符的 audience，追加到 URL 前须编码。
来源示例 2（bash）：
## [中文] 按本小节获取或重读当前外部身份令牌，交由SDK交换为短期OpenAI令牌；提供商与服务账户ID是配置，令牌本身不得记录或提交版本库。
AUDIENCE="https://api.openai.com/v1"
ENCODED_AUDIENCE=$(jq -rn --arg audience "$AUDIENCE" '$audience | @uri')
TOKEN=$(curl -sSf -H "Authorization: bearer $ACTIONS_ID_TOKEN_REQUEST_TOKEN" \
"${ACTIONS_ID_TOKEN_REQUEST_URL}&audience=${ENCODED_AUDIENCE}" | jq -r .value)
export TOKEN
主要声明：iss 是 https://token.actions.githubusercontent.com；aud 是请求的精确受众；sub 由仓库、分支、标签、PR 或环境等元数据生成；repository 如 my-org/my-repo，repository_owner 如 my-org；ref 如 refs/heads/main 或 refs/tags/v1.0.0；workflow 使用真实签发值（例如 deploy）；workflow_ref 如 my-org/my-repo/.github/workflows/deploy.yml@refs/heads/main；使用环境时有 environment（如 production）。run_id、run_number、run_attempt、job_workflow_ref 可辅助审计或高级规则。完整字段与主体格式见 GitHub OIDC 参考。
检查令牌
配置前导出 TOKEN，在 runner 本地检查：

来源示例 9（json）：
中文说明：来源的JSON数据或配置/输出片段，保留字段和值；令牌声明中的iss/aud/sub等须对照真实工作负载，解码本身不等于验签。
{
"iss": "https://token.actions.githubusercontent.com",
"aud": "https://api.openai.com/v1",
"sub": "repo:my-org/my-repo:environment:production",
"repository": "my-org/my-repo",
"repository_owner": "my-org",
"ref": "refs/heads/main",
"workflow": "deploy",
"workflow_ref": "my-org/my-repo/.github/workflows/deploy.yml@refs/heads/main",
"environment": "production",
"run_id": "1234567890",
"run_attempt": "1"
}
重点比较 iss、aud、repository、ref、workflow_ref 与配置。
设置身份联合
先创建 GitHub 提供商，再添加可信工作流的服务账户映射。
设置工作负载身份提供商
- Name 唯一，例如
github-actions-prod，Description 标明生产工作流。 - OIDC Issuer URL 为
https://token.actions.githubusercontent.com；Audience 与工作流请求完全相同，例如your-wif-audience或https://api.openai.com/v1。 - 关闭上传 JWKS，使用 GitHub OIDC 发现与公钥。
repository、ref、workflow等可直接匹配，仅按需转换。名称github_repository配assertion.repository，自动存为openai.github_repository；未经匹配转换的原始openai.*声明不会用于该前缀映射。
设置服务账户映射
- Name 在提供商内唯一，例如
github-actions-main-deploy，Description 说明 main 的生产部署。 - 每个必须匹配的声明添加 Key/Value 行，所有行都须通过。例如：
来源示例 10（text）：
中文说明：来源的JSON数据或配置/输出片段，保留字段和值；令牌声明中的iss/aud/sub等须对照真实工作负载，解码本身不等于验签。
iss == "https://token.actions.githubusercontent.com"
aud == "https://api.openai.com/v1"
repository == "my-org/my-repo"
ref == "refs/heads/main"
workflow_ref == "my-org/my-repo/.github/workflows/deploy.yml@refs/heads/main"
高权限映射优先 workflow_ref，因为它锁定文件路径和 ref；工作流名称可改且多个文件可同名。界面分别输入 repository = my-org/my-repo、ref = refs/heads/main、workflow_ref = my-org/my-repo/.github/workflows/deploy.yml@refs/heads/main；使用环境时再加 environment = production。除非整个 owner 命名空间的仓库都应获得访问，否则不要只匹配 repository_owner == "my-org"。
- 选择目标 Project 与 Service account，例如
github-actions-prod-deploy。 - Permissions 可用
api.model.request、api.vector_store.read收窄；留空不增加 WIF scope 限制，但仍受服务账户权限约束。
在工作流中使用令牌
SDK 请求 GitHub OIDC，再交换为 OpenAI 令牌。工作流授予 id-token: write 并传递 WIF 设置；SDK 使用 job 暴露的 ACTIONS_ID_TOKEN_REQUEST_URL 与 ACTIONS_ID_TOKEN_REQUEST_TOKEN。示例工作流：
来源示例 11（yaml）：
## [中文] 按本节配置受众、工作负载身份和令牌挂载；受众必须与OpenAI提供商一致，生产环境须限定账户及权限。
name: deploy

push:
branches:

workflow_dispatch:
permissions:
id-token: write

run: node ./scripts/call-openai.js
将 OPENAI_WIF_AUDIENCE、OPENAI_IDENTITY_PROVIDER_ID、OPENAI_SERVICE_ACCOUNT_ID 存为 Actions variables；它们是配置 ID，不是 bearer 凭证。下列自定义主体令牌提供函数请求所配受众的 GitHub JWT，并交由 SDK 交换：

生产使用环境保护、审批或分支限制；按仓库与 repository、ref、environment、workflow_ref 约束映射，避免组织级广泛信任；CI/CD 与生产用不同 OpenAI 服务账户；不要给不可信 fork PR 生产凭证，因其可能运行攻击者代码；短期令牌仅按需交换；审计仓库转移、改名和权限变化，定期核对信任假设；优先精确声明匹配。
