我正在尝试对使用 Node.js/Express 运行的 Amazon SimpleDB 进行非常简单的测试。这是我正在使用的代码(当然,AWS 密钥/秘密已消毒):
var express = require('express');
var simpledb = require('simpledb');
var app = express.createServer();
var sdb = new simpledb.SimpleDB(
{keyed:'MYKEY', secret:'MYSECRET'}, simpledb.debuglogger);
app.get('/', function(req, res) {
console.log("about to list domains...");
sdb.listDomains(function(error, result, meta) {
console.log("listing domains, I think?");
});
});
app.listen(8888);
这是我得到的错误:
DEBUG: simpledb: 2012-04-06T01:34:24.856Z create {"keyid":"MYKEY","secret":"MYSECRET","secure":false,"consistent":true,"test":false,"maxtry":null,"expbase":null,"delaymin":null,"delayscale":null,"randomdelay":null} {"secure":false,"host":"sdb.amazonaws.com","path":"/","version":"2009-04-15","port":80}

我对 Node.js、simpledb 模块和 SimpleDB 本身还是很陌生,但这对我来说似乎是 simpledb 模块中的一个错误。否则我无法弄清楚我做错了什么 - 我相信我的密钥/秘密是有效的(因为我已经分别和一起测试了无效的设置,并且我从亚马逊返回了实际错误,表明密钥/秘密无效)。
不过,这个错误让我很困惑。有任何想法吗?
