你基本上需要一个辅助方法将流读入内存。这很好用:
You basically need a helper method to read a stream into memory. This works pretty well:
public static byte[] readFully(InputStream stream) throws IOException
{
byte[] buffer = new byte[8192];
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int bytesRead;
while ((bytesRead = stream.read(buffer)) != -1)
{
baos.write(buffer, 0, bytesRead);
}
return baos.toByteArray();
}
然后你打电话给:
public static byte[] loadFile(String sourcePath) throws IOException
{
InputStream inputStream = null;
try
{
inputStream = new FileInputStream(sourcePath);
return readFully(inputStream);
}
finally
{
if (inputStream != null)
{
inputStream.close();
}
}
}
不要混合文本和二进制数据 - 它只会导致眼泪。
Don't mix up text and binary data - it only leads to tears.
