问题发生在服务器端,parseDelimitedFrom()调用.

客户端：

    C2SGainCard.Builder s = C2SGainCard.newBuilder();
    C2SGainCard c2s = s.build();

    GameRequest.Builder  reqBuilder=GameRequest.newBuilder();
    reqBuilder.setBody(c2s.toByteString());
    reqBuilder.setName(C2SGainCard.class.getSimpleName());
    reqBuilder.setPlayerId("3");
    GameRequest request=reqBuilder.build();

    DataOutputStream os = new DataOutputStream(socket.getOutputStream());
    os.write(request.toByteArray());
    os.flush();
    os.close();
    socket.close();

服务器端：

    try{
        DataInputStream is = new DataInputStream(socket.getInputStream());
        GameRequest gameRequest = GameRequest.parseDelimitedFrom(is);
    }catch(Exception ex){
        System.out.println(ex.getMessage());
    }

这是另一个类似的问题：

客户端：

    C2SSell.Builder s = C2SSell.newBuilder();
    CardOnSell.Builder cardOnSell = CardOnSell.newBuilder();
    cardOnSell.setId(1);
    cardOnSell.setPlayerId(3);
    cardOnSell.setCardId(1);
    cardOnSell.setCurrentPrice(111);
    cardOnSell.setFixedPrice(555);
    cardOnSell.setDescription("cao");

    s.setCardOnSell(cardOnSell.build());

    C2SSell c2s = s.build(); 

套接字处理是一样的.

服务器端：

    DataInputStream is = new DataInputStream(socket.getInputStream());
    byte[] b = new byte[1024];
    int len=is.read(b);
    String as = new String(b,len);
    GameRequest gameRequest=GameRequest.parseFrom(as.getBytes());

事实证明服务器端将在parseFrom()再次调用时中断.但是当我评论两行时：

cardOnSell.setCurrentPrice(111);
cardOnSell.setFixedPrice(555);

在客户端上,parseFrom()调用刚刚工作没有问题.在frist我怀疑.proto文件有一些问题,并且已经证明那里没有问题……那么这个问题是怎么来的？那是因为我在parseFrom()调用之前错过了一些数据？
