我正在使用retrofit构建android应用程序作为我的httprequest连接到我的hapi服务器。我的服务器工作正常，我已经在邮递员和我的WebApps上测试过了。但我的改造无法连接到它。下面是我的代码。为了简单起见阅读我删除线是没有必要的：改装无法连接到hapi服务器本地主机？

我的服务器API链接：http://127.0.0.1:3000/auth

通知从我Log.w()方法的错误，以前说：

java.net.ConnectException：无法连接到/127.0.0.1:3000

也许这是只是我常见的错误，请帮助。

回答：

127.0.0.1是您的机器的本地主机/回送地址a（托管在哪台服务器上）。 127.0.0.1映射到机器的IP地址，因此http://127.0.0.1:3000/auth只能从您的机器访问。

现在，为了从任何其他机器（例如您的手机）访问http://127.0.0.1:3000/auth，您的机器（服务器）和设备（电话）应该在同一个网络上（例如相同的Wi-Fi）通过http://IPAddressOfYourMachine:3000/auth访问它。

在MacOs/Linux上，您可以在终端上使用ifconfig命令找出IP地址。在Windows机器上，命令是ipconfig。 IP地址的格式应为192.168.x.y.

因此，最终BASE_URL应该像http://192.168.x.y:3000

回答：

改造也没有任何问题。问题出在BASE_URL从你的android设备到你的服务器。

请检查服务器安装在您的计算机的本地IP地址（例如：192.168.1.103），然后更换与BASE_URL是如下面的例子

public static final String BASE_URL = "http://192.168.1.103:3000";
