复制代码 代码如下:

import java.io.ByteArrayOutputStream;

import java.io.InputStream;

//从输入流中获取数据并以字节数组返回

public class StreamTool {

/**

* 从输入流获取数据

* @param inputStream

* @return

* @throws Exception

*/

public static byte[] readInputStream(InputStream inputStream) throws Exception{

byte[] buffer = new byte[1024];

int len = -1;

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

while((len = inputStream.read(buffer)) != -1){

outputStream.write(buffer, 0, len);

}

outputStream.close();

inputStream.close();

return outputStream.toByteArray();

}

}
