Android 以 HTTPS 方式連結讀取 PHP 網頁資訊

//因網路上的解決方案大都以 http 方式處理,但為了安全上的考量我才試著用 https 的方式!

//以下程式碼為正式在使用中的部分代碼

//實際環境為 Android 2.1,2.2 搭配 php5.3 使用

import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;

import javax.net.ssl.SSLContext; //與 HTTPS 有關
import javax.net.ssl.TrustManager; //與 HTTPS 有關
