我使用与 winapi 一起使用的桌面程序开发了一个 android 应用程序，并且我尝试在没有应用程序服务器的情况下访问 google GCM 服务器。我找到了一个很好的例子，而且效果很好。但我需要通过 winapi 应用程序访问 GCM 服务器。我还开发了 android 应用程序，这有助于我理解如何使用这个示例，但是我无法转换为 winapi java 并且 winapi 是如此不同，而且我从未使用过诸如 Get、Post 之类的 winapi http 连接之类的东西。

...来人帮帮我。

public class TestSender {

你的问题对我来说不是很清楚。在windows中，如果你想访问Internet(http)，你可以使用WinInet或者WinHttp api set。
