我已经通过改造进行了一些 REST 调用，可以访问我本地 WiFi 网络上的本地 IP 地址，在移动端工作得很好，但是一旦在独立的穿戴应用程序上我有这个错误：

如果我用在线地址替换本地 IP 地址，它也可以在手表上正常工作。在移动应用程序上没问题，我可以正确访问本地或远程相同的 URL。两台设备都在同一个 WiFi 网络下。任何想法 ？

这个问题也一直困扰着我。情况似乎是，当 Android Wear 通过蓝牙（以及手机）连接到互联网时，http/web 调用会以某种方式被代理。

一个解决方案是禁用手机的蓝牙连接，这会强制 Android Wear 设备直接连接到您的本地 wifi（如果它首先支持 wifi），然后本地 API 请求就会神奇地开始工作。

一个更合适的解决方法（因为您不能真正要求您的用户在每次使用您的应用程序时断开与手机的蓝牙连接），似乎是使用NodeApi检查生成的电话节点是否在附近（使用Node.isNearby()），如果就是通过MessageClient自己代理API请求到你的手机，然后在手机上发出请求，最后回复结果。很麻烦，但对我来说，这是调用本地 API 的唯一可靠方法......

如果有人知道为什么 Google 会通过蓝牙代理这些呼叫，或者有其他解决此问题的建议，我也很想知道。

当与手机连接时，在这种情况下使用移动互联网 API 代码不起作用。请断开手机与磨损的连接，然后重试它会回复您。请查看此链接，我认为它对您有帮助：https ://www.sitepoint.com/connecting-to-web-services-with-android-wear/

Wear 将使用共享蓝牙连接，活动接口类型为 PROXY，而不是 WIFI。你可以检查它adb shell dumpsys netstats。在这种情况下，wear 与服务器不在同一个本地网络中，并且到服务器的套接字将超时。

一种解决方案是让您的服务器具有公共 IP 或主机名。另一个是在访问 API 之前使用 NetworkRequest 更改与 wifi 的连接。请看谷歌的示例：https ://github.com/googlesamples/android-WearHighBandwidthNetworking
