测试代码如下:
import java.io.ByteArrayOutputStream; import java.io.InputStream; import java.net.URL; public class TestNowapi { public static void main(String args[]) throws Exception { String longUrl = "http://www.baidu.com"; String SIGN = "4a9331cccbc3ff30dde78d0b51fb4239"; String APPKEY = "26835"; // URL u=new URL("http://api.k780.com/?app=shorturl.set&url=需要缩短的网址(需要urlencode)&appkey={APPKEY}&sign={SIGN}&format=json"); URL u=new URL("http://api.k780.com/?app=shorturl.set&url="+longUrl+"&appkey="+APPKEY+"&sign="+SIGN+"&format=json"); InputStream in=u.openStream(); ByteArrayOutputStream out=new ByteArrayOutputStream(); try { byte buf[]=new byte[1024]; int read = 0; while ((read = in.read(buf)) > 0) { out.write(buf, 0, read); } } finally { if (in != null) { in.close(); } } byte b[]=out.toByteArray( ); System.out.println(new String(b,"utf-8")); } }
