android eclipse针对web服务器设置http POST和GET

我需要帮助在android中使用eclipse设置应用程序

我以前没有在JAVA开发中使用eclipse，所以对于如何将这一切与android结合在一起，我有点生疏

我下载了一个脚本，用我的web服务器进行测试，该脚本被设置为在访问时生成输出（此时为JSON命名的值对）

我正在使用-
面向Java开发人员的Eclipse IDE
版本：Helios Service Release 2
构建id:20110218-0911

Android开发工具包
版本：10.0.1.v201103111512-110841

到目前为止的JAVA代码-

我在android.jar中看不到这些类

是否有一个更简单的示例，可以针对web服务器实现一个事务，以获取用于android java应用程序的namevaluepair（JSON）？

这些错误是因为您引用的类不是标准android发行版的一部分：请参阅和

Android重新打包Apache HTTP库的特定版本。如果您想使用这些类，您需要包含这些jar。

如何包含这些jar？如果我包含非标准的android jar，我会在android设备上运行时遇到问题吗？我不知道您需要包含哪些特定的Apache jar：我假设您使用的是以前的代码，所以无论从哪里获得代码，都应该指向正确的jar文件。只需将它们添加到eclipse项目中，您就可以开始了。你的设备应该没有问题。好的，我现在就把它整理好了。我已经将这些额外的包作为构建路径的一部分包含在内，不再出现这些错误
