一.通过URL获取网络图片
import java.io.IOException;import java.io.InputStream;import .HttpURLConnection;import .URL;/*** 获取网络图片流* * @param url* @return*/public InputStream getImageStream(String url) {try {HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();connection.setReadTimeout(5000);connection.setConnectTimeout(5000);connection.setRequestMethod("GET");if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {InputStream inputStream = connection.getInputStream();return inputStream;}} catch (IOException e) {System.out.println("获取网络图片出现异常，图片路径为：" + url);e.printStackTrace();}return null;}
二. 注意事项
传入的URL必须是以http://开头的,因为我们使用了HttpURLConnection，示例：
