InputStream、byte[]互转

InputStream转byte[]

 

private byte[] InputStreamToByte(InputStream is) throws IOException { ByteArrayOutputStream bytestream = new ByteArrayOutputStream(); int ch; while ((ch = is.read()) != -1) { bytestream.write(ch); } byte imgdata[] = bytestream.toByteArray(); bytestream.close(); return imgdata; }  

====================================================

byte[]转InputStream

 

byte[] data;InputStream is = new ByteArrayInputStream(data);  

 

 

PS：这个在apache的commons-io里面有工具

org.apache.commons.io.IOUtils
InputStream is ....
byte[] data = IOUtils.toByteArray(is);
