有时，我在初始化时遇到了Newtonsoft.Json.JsonReaderException。我正在使用Git的PusherClient库。异常抛出在另一个线程上，这特别麻烦。我在init中没有做任何特别的事情。我想我直接从Pusher .NET示例得到了这段代码：
if (!_isInitialized)
{
_pusher = new Pusher(_pusherKey);
_pusher.Connected += PusherConnected;
_pusher.ChannelAuthEndpoint = _authUri + HttpUtility.UrlEncode(_clientName);
_pusher.ConnectionStateChanged += PusherOnConnectionStateChanged;
_pusher.Connect();
}
Pusher Auth Endpoint是我在此初始化链中唯一的其他组件，它使用PusherProvider（在PusherRESTDotNet库中提供）来验证私有和在线通道请求。在auth提供程序中没有抛出异常。
我可以向这些库添加额外的日志记录，以发现正在发送的内容，以及导致JSON库出现打嗝的原因，但我不确定从Pusher角度来看应该是什么样的恢复路径;我试图保持Pusher .NET库的黑盒消费者。任何想法/想法都表示赞赏。
成功后，我从Pusher跟踪日志中获得以下内容：
Pusher Information: 0 : Websocket opened OK.
Pusher Information: 0 : Websocket message received: {"event":"pusher:connection_established","data":"{\"socket_id\":\"24213.760310\"}"}

以下失败时：

Pusher Information: 0 : Websocket message received: {"event":"pusher:connection_established","data":"{\"socket_id\":\"24102.767432\"}"}

Pusher Information: 0 : Websocket message received: {"event":"pusher:error","data":{"code":null,"message":"Cannot broadcast client event (connection not subscribed to channel private-HW-PusherChannel)"}}
