java如何調用接口方式

URL url = new URL(接口);

創建鏈接對方接口對象

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

設置請求屬性

conn.setRequestProperty("accept", "*/*");

conn.setRequestProperty("connection", "Keep-Alive");

conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");

設置是否向httpUrlConnection輸出，設置是否從httpUrlConnection讀入

conn.setDoOutput(true);

conn.setDoInput(true);

最後斷開鏈接,保證速度

conn.disconnect();

基本就這樣用需要更多的就要自己看api了
