Https 在 Android 上使用 DefaultHttpClient 返回 404？

Question

我有一个使用 http://blah.com 的 http 请求，现在我被要求使用 https://blah.com

前者有效，后者因网络 I/O 错误而失败。客户端是否缺少我需要的参数设置？

网址请求：

D/MyAppWebservice(23142): http-transform :) [https://cdp.mobibob.com:8151/DoTransaction]

以下是日志：

Https 几乎总是意味着正在使用不同的端口（标准 http=>80；标准 https=>443）。您有一个硬编码端口 (8151)。我猜 https servlet 正在侦听不同的端口。

或者您正在尝试连接到不支持 https 的服务器。
