使用 API 接入 Github Copilot 提供的模型

1. 获取 GitHub access token（Device Flow）

1.1 申请 device code

export CLIENT_ID="Iv1.123456"
export SCOPE="read:user"

curl -sS -X POST "https://github.com/login/device/code" \
  -H "Accept: application/json" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  --data-urlencode "client_id=${CLIENT_ID}" \
  --data-urlencode "scope=${SCOPE}"
{"device_code":"9c2e1edec2cb88521acfeda02f1cb23sb4ceedfa","user_code":"E12E-8762","verification_uri":"https://github.com/login/device","expires_in":899,"interval":5}

你会得到 JSON：device_code, user_code, verification_uri, expires_in, interval。

1.2 打开浏览器授权

访问 verification_uri，输入 user_code，同意授权。

1.3 轮询换 GitHub access token

export DEVICE_CODE="9c2e1edec2cb88521acfeda02f1cb23sb4ceedfa"

curl -sS -X POST "https://github.com/login/oauth/access_token" \
  -H "Accept: application/json" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  --data-urlencode "client_id=${CLIENT_ID}" \
  --data-urlencode "device_code=${DEVICE_CODE}" \
  --data-urlencode "grant_type=urn:ietf:params:oauth:grant-type:device_code"
{"access_token":"ghu_af2cHWUGwwyJ3SOKh7crBAHUplj72900zMne","token_type":"bearer","scope":""}

成功返回 access_token 后：

export GH_OAUTH_TOKEN="ghu_af2cHWUGwwyJ3SOKh7crBAHUplj72900zMne"

2. 用 GitHub token 交换 Copilot token

curl -sS -X GET "https://api.github.com/copilot_internal/v2/token" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer ${GH_OAUTH_TOKEN}"
{
  "agent_mode_auto_approval": true,
  "annotations_enabled": true,
  "azure_only": false,
  "blackbird_clientside_indexing": false,
  "chat_enabled": true,
  "chat_jetbrains_enabled": true,
  "code_quote_enabled": true,
  "code_review_enabled": true,
  "codesearch": true,
  "copilotignore_enabled": false,
  "endpoints": {
    "api": "https://api.individual.githubcopilot.com",
    "origin-tracker": "https://origin-tracker.individual.githubcopilot.com",
    "proxy": "https://proxy.individual.githubcopilot.com",
    "telemetry": "https://telemetry.individual.githubcopilot.com"
  },
  "expires_at": 1772778126,
  "individual": true,
  "limited_user_quotas": null,
  "limited_user_reset_date": null,
  "prompt_8k": true,
  "public_suggestions": "disabled",
  "refresh_in": 1500,
  "sku": "free_engaged_oss_quota",
  "snippy_load_test_enabled": false,
  "telemetry": "enabled",
  "token": "tid=ssadead212edf672efe596beb27864df;exp=1772778126;sku=free_engaged_oss_quota;proxy-ep=proxy.individual.githubcopilot.com;st=dotcom;chat=1;cit=1;malfil=1;editor_preview_features=1;agent_mode=1;agent_mode_auto_approval=1;mcp=1;ccr=1;rt=1;8kp=1;ip=144.17.10.158;asn=AS14618:72k39821h13236e651efeed9hjyuuyj8fa5927f4ac7f2cddfasdfasd882baec02",
  "tracking_id": "ssadead212edf672efe596beb27864df",
  "vsc_electron_fetcher_v2": false,
  "xcode": true,
  "xcode_chat": false
}

把返回 JSON 里的 token 保存：

export COPILOT_TOKEN="tid=ssadead212edf672efe596beb27864df;exp=1772778126;sku=free_engaged_oss_quota;proxy-ep=proxy.individual.githubcopilot.com;st=dotcom;chat=1;cit=1;malfil=1;editor_preview_features=1;agent_mode=1;agent_mode_auto_approval=1;mcp=1;ccr=1;rt=1;8kp=1;ip=144.17.10.158;asn=AS14618:72k39821h13236e651efeed9hjyuuyj8fa5927f4ac7f2cddfasdfasd882baec02"

同时你也可以验证 Copilot internal 用户信息（这一步用的是 GitHub token，不是 Copilot token）：

curl -sS -X GET "https://api.github.com/copilot_internal/user" \
  -H "Authorization: token ${GH_OAUTH_TOKEN}" \
  -H "Editor-Version: vscode/1.96.2" \
  -H "User-Agent: GitHubCopilotChat/0.26.7" \
  -H "X-Github-Api-Version: 2025-04-01" \
  -H "Accept: application/json"

3. 用 Copilot token 调用模型（验证连通性）

3.1 测试 /models 模型列表接口

export COPILOT_BASE_URL=https://api.individual.githubcopilot.com

curl -i -sS -X GET "${COPILOT_BASE_URL}/models" \
  -H "Authorization: Bearer ${COPILOT_TOKEN}" \
  -H "Accept: application/json" \
  -H "Editor-Version: vscode/1.96.2" \
  -H "User-Agent: GitHubCopilotChat/0.26.7"
