Question

我正在尝试做一个简单的thrift序列化/反序列化但是如果我的反序列化失败，则显示以下消息：

/home/przemek/workspace/leviathan/node_modules/thrift/lib/thrift/protocol.js:350
      throw Error("Invalid type: " + type);
            ^
Error: Invalid type: 
    at Error (unknown source)
    at TBinaryProtocol.skip (/home/przemek/workspace/leviathan/node_modules/thrift/lib/thrift/protocol.js:350:13)
    at Object.Profile.read (/home/przemek/workspace/leviathan/gen-nodejs/Profile_types.js:49:15)
    at deserialize (/home/przemek/workspace/leviathan/client.js:43:13)
    at /home/przemek/workspace/leviathan/client.js:51:2
    at serialize (/home/przemek/workspace/leviathan/client.js:35:3)
    at Object.<anonymous> (/home/przemek/workspace/leviathan/client.js:49:1)
    at Module._compile (module.js:449:26)
    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:356:32)

我不明白为什么会这样。对我来说，这个错误消息听起来像是错误的类型，但我的序列化工作，所以序列化的对象应该具有正确的类型。执行TBinaryProtocol.prototype.skip时，protocol.js文件会抛出此错误。这是我的代码：

function serialize(data, callback) {
    var buffer = new Buffer(data);
    var transport = new thrift.TFramedTransport(buffer);
    var protocol = new thrift.TBinaryProtocol(transport);

    data.write(protocol);

    callback(transport.outBuffers)
 }

 function deserialize(data, callback){
    var transport = new thrift.TFramedTransport(data);
    var protocol  = new thrift.TBinaryProtocol(transport);
    var aProfile = new profile.Profile();

    aProfile.read(protocol);

    callback(aProfile);
 }

var aProfile = new profile.Profile({exposure:2,kineticCycleTime:3});
serialize(aProfile, function(serialized){
    log('serialization complete:' + serialized);
    deserialize(serialized, function(deserialized){
        log('deserialization complete');
        log(JSON.stringify(deserialized));
    });
});

我们在node.js中有一些thrift问题（使用一些差异库）我们编写了一些示例，其中添加了一些修复，请在那里查看 - https://github.com/imysak/using-thrift
