无法从@aws/凭据提供程序导出fromIni

Question

我正在开发一个React/Node.js应用程序，并试图从~/..aws/凭据文件中读取我的IAM用户凭据。我正在尝试使用@aws/凭证提供者节点包中的fromIni。根据AWS v3文档，我可以做以下工作：

import { fromIni } from "@aws-sdk/credential-providers"; // ES6 import
// const { fromIni } = require("@aws-sdk/credential-providers"); // CommonJS import

const client = new FooClient({
  credentials: fromIni({
    // Optional. The configuration profile to use. If not specified, the provider will use the value
    // in the `AWS_PROFILE` environment variable or a default of `default`.
    profile: "profile",
    // Optional. The path to the shared credentials file. If not specified, the provider will use
    // the value in the `AWS_SHARED_CREDENTIALS_FILE` environment variable or a default of
    // `~/.aws/credentials`.
    filepath: "~/.aws/credentials",
    // Optional. The path to the shared config file. If not specified, the provider will use the
    // value in the `AWS_CONFIG_FILE` environment variable or a default of `~/.aws/config`.
    configFilepath: "~/.aws/config",
    // Optional. A function that returns a a promise fulfilled with an MFA token code for the
    // provided MFA Serial code. If a profile requires an MFA code and `mfaCodeProvider` is not a
    // valid function, the credential provider promise will be rejected.
    mfaCodeProvider: async (mfaSerial) => {
      return "token";
    },
    // Optional. Custom STS client configurations overriding the default ones.
    clientConfig: { region },
  }),
});

但是，当我在我的index.js文件中尝试这个时：

import { fromIni } from '@aws-sdk/credential-providers';

const createLink = {
  url: config.aws_appsync_graphqlEndpoint,
  region: config.aws_appsync_region,
  auth: {
    type: config.aws_appsync_authenticationType,
    credentials: fromIni()
  }
};

然后运行npm start，得到以下错误：

export 'fromIni' (imported as 'fromIni') was not found in '@aws-sdk/credential-providers' (possible exports: fromCognitoIdentity, fromCognitoIdentityPool, fromTemporaryCredentials, fromWebToken)

我想要的函数似乎不是从包中导出的，但是文档中却不这么说。

编辑:输出到@aws-sdk/credential-providers @aws-sdk/credential-provider-ini

更新:在做了更多的研究并与一些AWS专家交谈后，我们发现我们需要使用Amazon来获得基于浏览器的应用程序的凭据。

在使用fromIni()对简单的CreateInvalidationCommand使用CloudFrontClient时，我也会遇到同样的错误。

尝试在没有credentials键的情况下配置客户端会导致Error: Credential is missing

我当前在本地开发的解决方法是使用.env.local文件，并使用accessKeyId和secretAccessKey属性来配置：

const cloudfront = new CloudFrontClient({
  credentials: {
    accessKeyId: process.env.REACT_APP_AWS_ACCESS_KEY_ID,
    secretAccessKey: process.env.REACT_APP_SECRET_ACCESS_KEY,
  },
  region: "us-east-1",
});

这显然并不理想，但它在本地用于测试和开发。

我还想指出，出口产品中也缺少fromEnv()。这会在EC2实例中引发此解决方案的问题。

不管是哪种方式，都希望能在不久的更新中看到这个问题得到解决。
