为什么需要它:当用户走「唤起 LINE App / 系统浏览器」授权时,LINE 把重定向发给 * 注册的 redirect_uri(后端 https URL),uniapp(另一个 App)无法在中间截获 code。这时必须由 * 后端接住回调、换 token、完成登录,再把结果 302 跳回 App(自定义 scheme)。原 {@code /oauthLogin} * 保留不动,覆盖「前端自己拿到 code 再 POST 给后端」的另一种场景(H5 / webview / SDK)。 * *

流程:LINE → {@code GET /auth/line/callback?code=...&state=...} * → {@link OAuthVerifyService#verify verify("line", code)}(code 换 token 取 userId) * → 查 info_user_oauth:已绑定→签 JWT token;未绑定→生成 tempKey(needPhone) * → 302 跳到 {@code oauth.line.app-redirect}(如 com.twanmsdyh.app://oauthLogin)带结果: *

* *
