Question

我有一个带有此属性的Avro架构：

{"name": "whenDate", "type": ["date", "null"]}

我正在使用Python客户端和生产者

confluent_kafka.avro.AvroProducer

当我使用上述属性加载Avro架构时，我触发了这个错误：

not a valid Avro schema: Type property "[u'date', u'null']" not a valid 
Avro schema: Union item must be a valid Avro schema: Could not make an Avro Schema object from date.

我认为此错误说明了Avro架构的Confluent解析器中的限制。也就是说，date是指定为here的逻辑类型，但Confluent解析器尚未支持它。

任何人都可以确认吗？更一般地说，我应该假设Confluent解析器不处理Avro架构的逻辑类型吗？感谢。

这是一种逻辑类型，我认为你只需要将它声明为一个。

var app = {};

    app.character = (function() {
        // the character manipulation object
        // this will be used to create character objects
        function _createCharacter(name) {
            return {
                // Just an example
                name: name,
                stats: { health: 10, level: 1 },
                weapon: {}
            };
        }
        return {
            createCharacter: _createCharacter
        };
    })();

    app.items = {};

    app.items.gear = (function() {
        // the gear manipulation object
        // this will be used to create gear objects
        function _createGear() {
            return {
                name: 'Sword',
                mods: { damage: 3, strength: 1 } // In reality it's random
            };
        }
        return {
            createGear: _createGear
        };
    })();

    app.game = (function() {
        var _player = {};
        //this.character = character;
        // closed functions in this area
        function _giveWeapon() {
            _player.weapon = app.items.gear.createGear();
        }
        function _newPlayer(name) {
            //_player = this.character.createCharacter(name);
            _player = app.character.createCharacter(name);
            
            _giveWeapon();
        }
        function _getPlayer() {
            return _player;
        }
        return {
            getPlayer: _getPlayer,
            newPlayer: _newPlayer
        };
    })();
    
    app.game.newPlayer('Ryan');
    console.log(app.game.getPlayer());
