AmazonError：我们计算的请求签名与您提供的签名不匹配

Question

我正在尝试连接到 aws 服务器，但我从 dynamo DB connect 收到此错误。

代码是这样的。

vuaws.dbclient().getItem('users', usrname, opts, function(err, data) {
      if (err || !data) {
        vulog.error('ddb: error in finding user \n',err);
      } else {
        vulog.debug('user got from db: ');

DB客户端就是这样一个函数。

  dbclient: function() {
    return dynode;
  },

参数是这个。

users admin@gmail.com { ConsistentRead: true,
  AttributesToGet: [ 'role', 'password' ] }

我收到的完整错误是这样的。

{ AmazonError: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

  message: 'The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.',
  statusCode: 400,
  action: 'GetItem',
  retry: [Getter] }

在 vuaws.js 中的 dynamodb 就是这样定义的。

  dynode.auth(vuconst.dynodeauth);
    vulog.info('dynode.attached');
    var dynamodb = new AWS.DynamoDB();
    vulog.info('dynamodb connected:');

vuconst.dynodeauth

是这样的。

dynodeauth: {
    "accessKeyId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "secretAccessKey": "xxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "region": "us-west-2"
  },

有什么帮助吗？

当我在 aws-cli 和我的程序中使用其他凭据时，我曾经遇到过这个错误。只需从 aws-cli 注销即可。
