+ *
+ * 提供两种模式，二选一即可：
+ *   · uploadDirect()  模式B：向后端取签名 → 小程序直接传 OSS（省服务器带宽，推荐）
+ *   · uploadViaServer() 模式A：文件先传后端，由后端转存 OSS（改动最小，兼容现有流程）
+ *
+ * 依赖：utils/api.js 里的 request / BASE_URL
+ *
+ * ⚠️ 用模式B之前，必须先把 OSS 域名加进微信后台「上传域名（uploadFile 合法域名）」，
+ *    否则真机上会直接 fail（errMsg: url not in domain list）。
