有人可以分享有关如何vogels dynalite工作的信息吗?
以下是我在计算机上本地实例化数据库服务器的方法:
import dynalite from 'dynalite';
import packageJSON from '../package.json'
// Returns a standard Node.js HTTP server
const dynaliteServer = dynalite({ path: '../mydb', createTableMs: 50 })
dynaliteServer.listen(packageJSON.config.endpointPort, function (err) {
if (err) throw err
console.log('Dynalite started on port ' + packageJSON.config.endpointPort);
});
以下是我尝试初始化vogels的内容:
import packageJSON from '../package.json';
import AWS from 'aws-sdk';
import vogels from 'vogels';
export default function initContext() {
const AWSConfig = {
accessKeyId: packageJSON.config.KEY,
secretAccessKey: packageJSON.config.SECRET,
region: packageJSON.config.region,
endpoint: packageJSON.config.endpoint
};
//config AWD
AWS.config.update(AWSConfig);
//create dynamodb instance
const dynamodb = new AWS.DynamoDB(AWSConfig);
//config vogels AWS
vogels.AWS.config.update(AWSConfig);
vogels.dynamoDriver(dynamodb);
return {
dynamodb,
vogels
};
}
我已经定义了一个模型并尝试在名为initDB.js
的文件中创建它:
initContext();
myVogelsModel.create({
name: 'foo',
email: 'foo@example.com',
}, function (err, model) {
console.log(err);
});
但它只返回了我的错误:
{ [ResourceNotFoundException: Requested resource not found]

任何提示都将不胜感激:)

问题已解决。
问题似乎是我用一个定义为Number的键创建了表(使用aws-sdk-js dynamodb.createTable
函数),而我的Vogels模型的键是UUID
(又名string
)
当尝试使用vogels在表中添加项时:它不起作用:因为使用命令aws dynamodb list-tables --endpoint-url http://localhost:4567
而感到困惑:我得到了正确的表列表。
所以我尝试使用函数vogels vogels.createTables
创建表。之后,调用myVogelsModel.create函数完全正常。
