Question

我正在自学android开发。首先，我使用apache http utils在android上实现了一个web服务器，它在模拟器上浏览到localhost:8080时提供登录页面。

我想知道如何在Android服务器端解析登录请求。这个Web服务器基于Uri请求即时提供内容。当提交登录页面时，表单被发布到/login.do ，在localhost: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主体并相应地提供html。我在表单中只有一个字段解析即password。我只能读取请求标题。

任何有正确方向的想法或指示都会非常感激。谢谢

我在apache网站上找不到任何适用于我的案例的资源。是否可以直接从网址读取请求者？

环顾四周后，我找到了解决方案。在handle方法中添加以下内容就可以了。感谢原始海报。http://www.androiddevblog.net/android/a-bare-minimum-web-server-for-android-platform

            if (request instanceof HttpEntityEnclosingRequest) {
    HttpEntity entity = ((HttpEntityEnclosingRequest) request).getEntity();
    if (entity != null) {
    Log.v("RequestBody", EntityUtils.toString(entity, "UTF-8"));
    entity.consumeContent();
    }
    }
