在 AWS Cloudfront 中创建一个新的行为，将该行为设置为允许所有的 HTTP 方法，然后将 Cookie 设置为“*”，然后将该行为与 AWS Cognito 连接。此外，在 AWS Cognito 中，确保“授权范围”中包含您允许用户从 Cloudfront 访问的资源。

以下是一个示例 Node.js 代码，用于设置 AWS Cloudfront 行为：

const AWS = require('aws-sdk');
const cloudfront = new AWS.CloudFront();

// 创建一个新的 Origin，连接到我们的 Cognito 用户池
const userPoolId = 'YOUR_USER_POOL_ID';
const cognitoOrigin = {
  Id: `cognito-${userPoolId}`,
  DomainName: `${userPoolId}.auth.us-east-1.amazoncognito.com`,
  CustomHeaders: {
    'host': [{
      Key: 'host',
      Value: `${userPoolId}.auth.us-east-1.amazoncognito.com`
    }]
  },
  OriginPath: '/oauth2',
  OriginProtocolPolicy: 'https-only',
  CustomOriginConfig: {
    HTTPPort: 443,
    HTTPSPort: 443,
    OriginSslProtocols: {
      Items: ['TLSv1.2'],
      Quantity: 1
    },
    OriginReadTimeout: 30,
    OriginKeepaliveTimeout: 5
  }
};

// 创建新的 Cloudfront 行为，将其设置为允许所有 HTTP 方法
const createBehavior = cloudfront.createDistribution.bind(cloudfront);
const newBehaviorParams = {
  DistributionId: 'YOUR_DISTRIBUTION_ID',
  IfMatch: 'ETAG_VALUE',
  DefaultCacheBehavior: {
    AllowedMethods: {
      Items: ['HEAD', 'GET', 'OPTIONS', 'PUT', 'POST', 'PATCH', 'DELETE'],
      Quantity: 7,
      CachedMethods: {
        Items: ['HEAD', 'GET', 'OPTIONS'],
        Quantity: 3
      }
    },
    CachedMethods: {
      Items: ['HEAD', 'GET', 'OPTIONS'],
      Quantity: 3
    },
    TargetOriginId: 'THE_ID_OF_YOUR_ORIGIN',
    ForwardedValues: {
      QueryString: true,
      Cookies: {
        Forward: 'all',
        WhitelistedNames: {
          Quantity: 0
        }
      },
      Headers: {
        Quantity: 0
      },
      QueryStringCacheKeys: {
        Quantity: 0
      }
    },
    MinTTL: 60,
    ViewerProtocolPolicy: 'redirect-to-https',
    Compress: true,
    SmoothStreaming: false,
    DefaultTTL: 86400,
    MaxTTL: 31536000,
    LambdaFunctionAssociations: {

    },
    FieldLevelEncryptionId: '',
    TrustedSigners: {
      Enabled: false,
      Quantity: 0
    }
  },
  CacheBehaviors: {
    Quantity: 0
  }
};

createBehavior(newBehaviorParams, (err, data) => {
  if (err) {
    console.error(err, err.stack);
  } else {
    console.log(data);
  }
});
