网上的图片用流读取
如果path 是一个 网址路径
如 http://www.javaweb.top/images/shuji.png
path= http://www.javaweb.top/images/shuji.png;
File file=new File(path);
InputStream in = new FileInputStream(file);
InputStream in = new FileInputStream(file);
这个会报错。。
用这个转就行
URL url=new URL(path);
InputStream in = url.openStream();
InputStream in = url.openStream();
