一.通过URL获取网络图片
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.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
