Au cœur des protocoles

从连接配置、结构定义到响应校验，逐步构建可靠的结构化 JSON 流程，并处理模型兼容性、拒答、截断与降级。

用七个步骤构建模型接口集成测试，覆盖请求校验、响应夹具、重试、流式输出与工具调用，并明确模拟测试与真实契约验证的边界。

通过七个步骤正确理解请求与令牌配额、重置时间和重试提示，避免单位误读、重复重试与并发争抢。

从环境变量、客户端初始化到最小请求、错误排查和上线检查，逐步配置 Node.js SDK 的替代端点，避免路径、密钥和重试策略中的常见问题。

通过一个 OpenAI 兼容接口，逐步构建支持模型切换、流式输出和错误处理的轻量命令行工具。

用七个步骤排查企业代理、证书、鉴权与流式响应，让命令行工具和 API 客户端共享可验证、可维护的连接配置。
