AWS SDK 配置中缺少凭据

Question

错误：可能未处理的承诺拒绝（id：0）： CredentialsError：配置中缺少凭据，如果使用 AWS_CONFIG_FILE，请设置 AWS_SDK_LOAD_CONFIG=1

我在 React Native (0.64.0) 项目中使用 "aws-sdk": "^2.918.0"。我是运行使用节点 v14.17.0 和 Windows 10 版本 21H1 OS build 19043.985:

的程序

// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');

AWS.config.update({
  region: 'us-east-1',
  maxRetries: 3,
  httpOptions: {timeout: 30000, connectTimeout: 5000},
});

// Create the DynamoDB service object
var ddb = new AWS.DynamoDB({
  apiVersion: '2012-08-10',
});

console.log('ddb: ', ddb);

~/.aws/config

[default]
region=us-east-1
output=json

[profile myName]
region = us-east-1
output = json

~/.aws/credentials

[default]
aws_access_key_id=XXX...
aws_secret_access_key=XXX...

[mateo\.lara]
aws_access_key_id=XXX...
aws_secret_access_key=XXX...

使用 ddb 查询数据库时，我收到此 CredentialsError，尽管我已在 AWS CLI 中配置了我的凭据 (aws-cli/2.2.6 Python/3.8.8 Windows/10 exe/AMD64 prompt/off)。你知道可能是什么问题吗？以及如何解决？

------------------------------------ 编辑 ------ ------------------------------

按照@nishkaush 的建议，我尝试将 AWS_SDK_LOAD_CONFIG=1 添加到配置文件中，并且尝试删除凭证文件并将 aws_access_key_id 和 aws_secret_access_key 添加到配置中文件没有成功。

这是 ddb 日志的输出：

ddb:  {"CALL_EVENTS_BUBBLE": [Function CALL_EVENTS_BUBBLE], "MONITOR_EVENTS_BUBBLE": [Function EVENTS_BUBBLE], "_clientId": 1, "_events": {"apiCall": [[Function CALL_EVENTS_BUBBLE]], "apiCallAttempt": [[Function EVENTS_BUBBLE]]}, "config": {"apiVersion": "2012-08-10", "apiVersions": {}, "clientSideMonitoring":

Answer 1

在您的 ~/.aws/config 文件中，您能否也尝试这样设置：

..
..
AWS_SDK_LOAD_CONFIG=1

或者，您可以尝试删除 ~/.aws/credentials 文件并将 aws_access_key_id 和 aws_secret_access_key 移动到 ~/.aws/config 文件，如下所示：

[default]
region=us-east-1
output=json
aws_access_key_id = XXX
aws_secret_access_key = XXX

Answer 2

首先感谢nishkaush和Jatin Mehrotra的帮助。最后，我解决问题的唯一方法是将 'accessKeyId' 和 'secretAccessKey' 直接添加到我的 AWS.config.update。这绝不是最终的解决方案，您应该避免将凭据直接放入您的代码（出于安全原因）。请注意，如果您打算使用此解决方案，则应通过 .env 文件设置您的凭据并将其添加到 gitignore 以保护您的凭据。我本来想使用共享凭据文件配置我的凭据，但我运行没时间了，问题仍然存在。如果对您有帮助，请查看：

话虽如此，问题可能与我正在使用 react native 有关，无论如何这是解决方案：

AWS.config.update({
  maxRetries: 3,
  httpOptions: {timeout: 30000, connectTimeout: 5000},
  region: 'us-east-1',
  accessKeyId: 'XXXX...',
  secretAccessKey: 'XXXX...',
});
