读取网络数据流

public static void readAsFile(InputStream inStream, File file) throws Exception
{//读取网络InputStream
FileOutputStream outStream = new FileOutputStream(file); //自定义FileOutputStream对象
byte[] buffer = new byte[1024]; //自定义byte[]缓冲
int len = -1; //用于记录InputStream流的读入字节长度
while( (len = inStream.read(buffer)) != -1 )
{
outStream.write(buffer, 0, len); //写入文件
}

outStream.close(); //关闭FileOutputStream流
inStream.close(); //关闭InputStream流
}
