HttpUrlConnection get,post傳輸

HttpUrlConnection get,post傳輸

這裡沒有寫UI操作，get請求中文亂碼問題這裡也沒有處理，如果做UI操作,需要在子線程中，這裡主要講解get,post如何傳遞數據，其他知識就不考慮了

package com.example.httpurlconnectiontest;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.ProtocolException;
import java.net.URL;

import android.content.Context;
import android.widget.Toast;
