byte[]和InputStream的相互转换如下:
1:byte[]转换为InputStream流
InputStream sbs = new ByteArrayInputStream(byte[] buf);
2:InputStream转换为byte[]数组
ByteArrayOutputStream swapStream = new ByteArrayOutputStream();
byte[] buff = new byte[100]; //buff用于存放循环读取的临时数据
int rc = 0;
while ((rc = inStream.read(buff, 0, 100)) > 0) {
swapStream.write(buff, 0, rc);
}
byte[] in_b = swapStream.toByteArray(); //in_b为转换之后的结果

}
