UnrecognizedClientException","errorMessage":"在本地测试 lambda 函数时，请求中包含的安全令牌无效

Question

我正在尝试使用 aws sam 在本地调用我的 lambda 函数进行测试。该函数从 dynamodb table 中读取一个项目。我已经启动了一个本地 dynamodb 容器，其中创建了所需的 table。

运行以下命令创建本地 dynamodb 容器。

docker 网络创建 lambda-local
docker 运行 —-network=lambda-local —-name users -d -p 8000:8000 amazon/dynamodb-local
aws dynamodb create-table --table-name employees --attribute-definitions AttributeName=name,AttributeType=S --key-schema AttributeName=name,KeyType=HASH -- 键类型预配吞吐量 ReadCapacityUnits=5,WriteCapacityUnits=5 --endpoint-url=http://127.0.0.1:8000

然后使用下面的命令我能够验证就本地 dynamodb 而言一切正常。

aws dynamodb list-tables --endpoint-url http://localhsot:8000

但是，当我尝试运行下面的命令时，出现错误。

sam local invoke <lambdaFunctionName> --docker-network lambda-local

我得到的错误-

我在这里错过了什么？使用 sam 在本地调用 lambda 函数并将其连接到本地运行ning dynamodb 容器是否需要任何其他步骤？

lambda 代码

var AWS = require('aws-sdk');
AWS.config.update({region: 'us-east-1'});

exports.lambdaHandler = async (event, context) => {
    const dynamoDB = new AWS.DynamoDB.DocumentClient();
    const params = {
        TableName: 'employees',
        Key: {
            name: "naxi"
        }
    };

    const result = await dynamoDB.get(params).promise();
    if (result.Item) {
        return result.Item;
    } else {
        return { error: 'Task not found.' };
    }
};

您需要使用 AWS CLI 在本地机器上配置访问密钥和密钥以及区域。出现此错误是因为没有正确的访问密钥和密钥，或者没有配置它。

参考以下link： https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html
