手机系统android4.4
想上传图片到服务器
基本代码为：
public void addPart(final String key, final String fileName, final InputStream fis, String type, final boolean isLast)
{
writeFirstBoundaryIfNeeds();
try
{
type = "Content-Type: " + type + "\r\n";
out.write(("Content-Disposition: form-data; name=\"" + key + "\"; filename=\"" + fileName + "\"\r\n").getBytes());
out.write(type.getBytes());
out.write("Content-Transfer-Encoding: binary\r\n\r\n".getBytes());
final byte[] tmp = new byte[4096];
int l = 0;
//java.io.IOException: read failed: EBADF (Bad file number)
// Caused by: libcore.io.ErrnoException: read failed: EBADF (Bad file number)
while ((l = fis.read(tmp)) > 0)
{
out.write(tmp, 0, l);
}
if (!isLast)
out.write(("\r\n--" + boundary + "\r\n").getBytes());
else
{
writeLastBoundaryIfNeeds();
}
out.flush();
out.close();
fis.close();
}
catch (final IOException e)
{
e.printStackTrace();
}
}
报错点位于while ((l = fis.read(tmp)) > 0)这句代码。

很奇怪，这是什么引起的？
