大家好，我正在自学android开发。首先，我使用ApacheHTTPUTILS在android上实现了一个Web服务器，当在emulator上浏览到localhost:8080时，它会提供一个登录页面

我想知道如何在android服务器端解析登录请求。此web服务器根据请求的Uri动态提供内容。例如，当提交登录页面时，表单将发布到本地主机上的/login.do:8080

我已经为该操作注册了一个处理程序，如下所示。我想知道是否有办法在我的处理程序中解析请求体并相应地提供html。我在表单中只有一个字段要解析，即密码。我只能读取请求头

如果您有任何正确的想法或建议，我们将不胜感激。谢谢

我在apache站点上找不到任何适用于我的案例的资源。是否可以直接从url读取requestbody？

在查找了很久之后，我找到了解决方案。在handle方法中添加以下内容可以实现此目的。多亏了原始海报
