message: 'Missing region in config',
code: 'ConfigError',
我的代码是:
//Authenticate AWS:
var myCredentials = new AWS.CognitoIdentityCredentials(IdentityPoolId:'us-west-2a:"Identity Pool ID"');
var myConfig = new AWS.Config(
credentials: myCredentials, region: 'us-west-2a'
);
这是在使用 ejs 和节点的快速服务器上运行的。我正在使用 Amazon javascript SDK。
我在这里尝试了解决方案:
AWSCognito Missing region in config error
这没有帮助。
编辑 1:
根据下面的要求,我附上了完整的代码:
var express = require('express');
var AWS = require('aws-sdk');
var EC2 = require('aws-ec2')('access key', 'secret');
var scale = require('aws-scale');
var router = express.Router();
//Authenticate AWS:
var myCredentials = new AWS.CognitoIdentityCredentials(
IdentityPoolId:'us-west-2:b0efe3c7-e4c9-420f-836b-6d776e2a9271'
);
var myConfig = new AWS.Config(
credentials: myCredentials, region: 'us-west-2'
);
AWS.config = myConfig
var minInst = 1;
var maxInst = 3;
var ec2 = new AWS.EC2();
//Set up parameters for EC2 Instances:
var params =
ImageId: 'ami-6e1a0117',
MaxCount: minInst,
MinCount: maxInst,
InstanceInitiatedShutdownBehavior: 'terminate',
InstanceType: 't2.micro',
Monitoring:
Enabled: true
,
NetworkInterfaces: [
AssociatePublicIpAddress: true,
DeleteOnTermination: true,
],
Placement:
AvailabilityZone: 'us-west-2',
,
SecurityGroupIds: [
'sg-b0307ccd',
],
SecurityGroups: [
'CAB432Assignment2SG',
],
;
ec2.runInstances(params, function(err, data)
if (err)
console.log(err, err.stack); //An error occurred
else
console.log(data); //Successful Response
);
【问题讨论】:
另见:Configuring region in Node.js AWS SDK 【参考方案1】:像这样在你的配置中添加区域:
AWS.config.update(
region: "REGION" //Here add you region
);
请将其添加到最顶层(var ec2 = new AWS.EC2();
行上方)
【讨论】:
当我添加这个时它给了我一个凭据错误,我该如何添加凭据呢?【参考方案2】:俄勒冈地区的正确代码是us-west-2
。您在两个地方都设置为us-west-2a
。
在提及身份池ID的同时,更正如下代码并尝试:
AWS.config.update(region:'us-west-2');
var myCredentials = new AWS.CognitoIdentityCredentials(
IdentityPoolId:'us-west-2:"Identity Pool ID"'
);
如果您没有为 API CognitoIdentityCredentials 传递 区域,那么它将从 AWS.config。
另外,在您的代码中,在使用 region 名称初始化 AWS.CONFIG 时,您使用了 us-west-2a
。更正它,如果您打算使用它而不是 AWS.config.update。
var myConfig = new AWS.Config(
credentials: myCredentials, region: 'us-west-2'
);
更新
我发现了另一个问题。问题是,您正在使用 var myConfig = new AWS.Config()
初始化 AWS.config,但您不更新 AWS.config 类回来了。缺少的代码是:AWS.config = myConfig
。
由于您没有将其更新回来,并且您也没有使用 AWS.config.update(region:'us-west-2');
更新现有的默认类,因此它会引发 Missing region in config
错误。
正确的代码 sn-p
var AWS = require('aws-sdk');
var myCredentials = new AWS.CognitoIdentityCredentials(
IdentityPoolId:'us-west-2:identity-pool-id'
);
var myConfig = new AWS.Config(
credentials: myCredentials, region: 'us-west-2'
);
AWS.config = myConfig
【讨论】:
我已经更正了它,但我仍然得到同样的错误。 @ChristopherLittlewood 我已经更新了答案部分。 我现在收到错误消息:missing credentials in config
当我向下滚动时,它显示message: 'XMLHttpRequest is not defined'
。我已将您更正的解决方案复制到我的代码中。我唯一改变的是我的身份池 ID。
当我注释掉启动 EC2 机器的请求时,它似乎没有收到此错误。
这太令人惊讶了!!能够成功请求新的 EC2 实例。 config initialization 和 ec2.runInstances() 代码块都在同一个 .js 脚本中,对吗?你能附上你的整个代码吗?【参考方案3】:
上面的答案是正确的。
但是,对于aws-sdk-js-v3
,您不能全局设置AWS.config
。
因此,解决方法是:
process.env.AWS_REGION = 'us-west-2'
此外,如果您在 CI 构建期间收到有关无法访问 "169.254.169.254:80/latest/meta-data/iam/security-credentials/"
的错误,您可能希望以相同的方式设置虚假凭据:
process.env.AWS_REGION = 'us-west-2'
process.env.AWS_ACCESS_KEY_ID = 'test-key'
process.env.AWS_SECRET_ACCESS_KEY = 'test-secret'
【讨论】:
【参考方案4】:在您的情况下,这是执行顺序(这就是副作用不好的原因)。
错误:
var myCredentials = new AWS.CognitoIdentityCredentials(
IdentityPoolId:'us-west-2:b0efe3c7-e4c9-420f-836b-6d776e2a9271'
);
var myConfig = new AWS.Config(
credentials: myCredentials, region: 'us-west-2'
);
正确:
// update the config
var myConfig = new AWS.Config(
credentials: myCredentials, region: 'us-west-2'
);
// then create the instance
var myCredentials = new AWS.CognitoIdentityCredentials(
IdentityPoolId:'us-west-2:b0efe3c7-e4c9-420f-836b-6d776e2a9271'
);
