Question

我的Android应用程序出现了一个奇怪的问题。我在硬编码服务器的IP地址时可以连接和发送数据，但是当我尝试使用主机名时，我会收到以下错误。我一直在Windows服务器2003上通过android的模拟器测试这个。我还确保地址以http开头并且应用程序使用了互联网的许可。关于为什么会这样的任何想法？ E.G我可以在使用123.45.678 / test.php而不是servername / test.php时连接

我的问题是我公司的特殊权限，我不明白。出于安全考虑，我无法使用我的应用程序进行连接。但是，如果其他人遇到了我遇到的同样问题（我只想托管一个PHP脚本来使用POST），请使用Google App Engine。我现在一直在使用它，这是我一直在寻找的一切。 https://appengine.google.com/

Android应用无法连接到主机名，但可以连接到服务器上的IP
