Node.js 来自 Nodeaws 的 Dynamo Local：所有操作都失败无法对不存在的表执行操作

我有一台本地发电机正在运行.我已经使用JavaScript控制台设置了我的表，它们从那里列出OK.

我还可以从JavaScript控制台向我的表中放置和获取项目:

var params = { TableName:"environmentId", Item: { environmentId: {"S":"a4fe1736-98cf-4560-bcf4-cc927730dd1b"} }};
dynamodb.putItem(params, function(err, data) {
    console.log("put : err was " + JSON.stringify(err) + " and data is " + JSON.stringify(data));
});

打印put : err was null and data is {}张我认为是"成功"的因为

params = { "Key":{"environmentId":{"S":"a4fe1736-98cf-45e0-bcf4-cc927730dd1b"}},"TableName":"environmentId"}
dynamodb.getItem(params, function(err, data) {
    console.log("get : err was " + JSON.stringify(err) + " and data is " + JSON.stringify(data));
});

打印get : err was null and data is {"Item":{"environmentId":{"S":"a4fe1736-98cf-45e0-bcf4-cc927730dd1b"}}}张，即检索我刚刚放在桌子上的对象.

但是，如果启动 node REPL并键入:

var AWS = require('aws-sdk');
AWS.config.loadFromPath("./config/credentials.js");
endpoint = new AWS.Endpoint("http://localhost:8000");
var dynamoOpts = {apiVersion: '2012-08-10', 'endpoint':endpoint};
var dynamodb = new AWS.DynamoDB(dynamoOpts);
var params = { TableName:"environmentId", Item: { environmentId: {"S":"a4fe1736-98cf-4560-bcf4-cc927730dd1b"} }};
dynamodb.putItem(params, function(err, data) {
    console.log("put : err was " + JSON.stringify(err) + " and data is " + JSON.stringify(data));
}

我得到一个未找到资源错误:

{ "message":"Cannot do operations on a non-existent table",
    "code":"ResourceNotFoundException",
    "time":"2015-04 10T10:01:26.319Z",
    "statusCode":400,
    "retryable":false,
    "retryDelay":0
}

ASW.putCommand返回的请求对象具有正确的端点:

{ protocol: 'http:',
    host: 'localhost:8000',
    port: 8000,
    hostname: 'localhost',
    pathname: '/',
    // etc.

同样的事情也发生在我的 node 应用程序中，但是连接到真正的AWS托管dynamo的代码是一样的.
