BYOK (自带密钥)** - 在控制面板存储密钥 (Provider Keys > Add)，代码中无需密钥 **3. 请求头** - 每次请求传递提供商密钥： typescript const client = new OpenAI({ apiKey: process.env.OPENAI_API_KEY, baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`, defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` } }); ## API 令牌权限 - **网关管理：** AI Gateway - Read + Edit - **网关访问：** AI Gateway - Read (最低权限) ## 网关管理 API bash # 列表 curl https://api.cloudflare.com/client/v4/accounts/{account_id}/ai-gateway/gateways -H "Authorization: Bearer $CF_API_TOKEN" # 获取 curl .../gateways/{gateway_id} # 更新 curl -X PUT .../gateways/{gateway_id} -d '{"cache_ttl":7200,"rate_limiting_limit":200}' # 删除 curl -X DELETE .../gateways/{gateway_id} ## 获取 ID - **账户 ID：** 控制面板 > Overview > 复制 - **网关 ID：** AI Gateway > Gateway name 列 ## Python 示例 python from openai import OpenAI import os client = OpenAI( api_key=os.environ.get("OPENAI_API_KEY"), base_url=f"https://gateway.ai.cloudflare
