如何發送請求標題？

Question

如何發送請求標頭？假設我想向網站發送HTTP請求時發送自己的請求標頭。

我該怎麼做？

URL url = new URL(urlString); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection(); 

// HOW DO I SEND REQUEST HEADER LIKE Date,Cookie,Cache-Control ??? 

Answer 1

connection.setRequestProperty("HeaderName", "Value"); 

Answer 2

獲得HttpURLConnection的連接後，你可以做如下

//adding headers 
con.setRequestProperty("headername", value);
