/**

* 签名流程：
|
|
|
* 1. 前端先准备业务参数（不含 signature）
|
|
|
* 2. 调用签名服务（同样走 /public），传入 { tag, path, query, body, timestamp, nonce }
|
|
|
* 3. 后端用 secret key 计算 HMAC-SHA256，返回 signature
|
|
|
* 4. 前端携带 signature/timestamp/nonce 调用真正网关入口 /public
|
|
|
*
|
|
|
* @param {Object} options
|
|
|
* - tag: 路由标签（必填），如 'pad.auth'
|
|
|
* - path: map.path 子路径（必填），如 '/login'
|
|
|
* - method: 业务含义上的 method（必填），如 'GET' / 'POST'，会写入 map.head.method
|
|
|
* - query: 对应 map.query 对象
|
|
|
* - body: 对应 map.body 对象
|
|
|
* - traceId: 可选，自定义链路号；不传则自动生成
|
|
|
* - withToken: 是否携带 token（登录等接口传 false）
|
|
|
* - skipSign: 是否跳过签名（登录 /login 时传 true，不调 /api/sign、不校验签名）
|
|
|
* - loading: 是否展示 loading
|
|
|
* - loadingText: loading 文案
