我试图实施DotNetty但有一个奇怪的问题？
错误讯息：
DotNetty.Buffers.IllegalReferenceCountException：＆＃39;此对象的非法引用计数为0＆＃39;

它在哪里发生？
class RankingForm(forms.ModelForm):
rank = forms.IntegerField(max_value=3, min_value=1)
position = forms.ModelMultipleChoiceField(queryset=Positions.objects.none())
class Meta:
model = Ranking
exclude = ['applicant']
fields = ['rank', 'position']
def __init__(self, *args, **kwargs):
super(RankingForm, self).__init__(*args, **kwargs)
self.fields['rank'].widget.attrs.update({'class': 'form-control'})
self.fields['position'].queryset = self.instance.positions.all()
这是完整的课程。
public bool HasLength => Buffer.GetInt(0) > -1;
这是调用public class ServerPacket
{
public IByteBuffer Buffer { get; }
public short Id { get; private set; }
public ServerPacket(short id)
{
Buffer = Unpooled.Buffer();
Id = id;
Buffer.WriteInt(-1);
Buffer.WriteShort(id);
}
public bool HasLength =>
Buffer.GetInt(0) > -1;
public void WriteByte(int b) =>
Buffer.WriteByte((byte)b);
public void WriteDouble(double d) =>
WriteString(d.ToString());
public void WriteString(string s) // d
{
Buffer.WriteShort(s.Length);
Buffer.WriteBytes(Encoding.Default.GetBytes(s));
}
public void WriteShort(int s) =>
Buffer.WriteShort(s);
public void WriteInteger(int i) =>
Buffer.WriteInt(i);
public void WriteBoolean(bool b) =>
Buffer.WriteByte(b ? 1 : 0);
}
方法的类。
HasLength如何发送ServerPacket实例？
public class Encoder : MessageToMessageEncoder<ServerPacket>
{
protected override void Encode(IChannelHandlerContext context, ServerPacket message, List<Object> output)
{
if (!message.HasLength)
{
message.Buffer.SetInt(0, message.Buffer.WriterIndex - 4);
}
output.Add(message.Buffer);
}
}
发送ServerPacket实例时会发生此错误，此处为代码。
public void SendPacket(ServerPacket packet)
{
_context.WriteAndFlushAsync(packet);
}
