Question

在使用基于websockets的编码器和解码器发送包含base64图像字符串的json对象期间，获得以下异常跟踪。从ClientEndpoint到ServerEndpoint

问题：如何避免这个或任何替代解决方案通过websockets发送base64图像字符串？

import javax.websocket.EncodeException;
import javax.websocket.Encoder;
import javax.websocket.EndpointConfig;



public class MessageEncoder extends ServerObject implements    Encoder.Text<Message> {

    @Override
    public String encode(Message message) throws EncodeException {
        info("MessageEncoding -- {}",message.getJson());
        return message.getJson().toString();
    }

    @Override
    public void init(EndpointConfig config) {
        info("MessageEncoder init ");
    }

    @Override
    public void destroy() {
       info("MessageEncoder destroy ");
    }

}

可记录错误：

javax.json.stream.JsonParsingException：org.glassfish.json.JsonTokenizer.readString期间出现意外的Char = Parse错误
