使用JavaScript SDK的AWS Cognito Developer身份驗證身份

Question

我需要使用JavaScript SDK實現Developer Authenticated Identities，但我遇到了問題。 我已經使用自定義身份驗證提供程序配置了標識池

在服務器上：

AWS.config = new AWS.Config({
    region: 'ap-northeast-2',   
    credentials: new AWS.Credentials('XXXXXS7FJBAOO5IXXXXX', 'XXXXXYBo4jmfsu7K0qJSFvu3nlVvYOcVz4GXXXXX')
});

var params = {
    IdentityPoolId: 'ap-northeast-2:a383cb2e-e302-4ff6-8d8f-70e3185XXXXX',
    Logins: {
        'com.abc.xyz': '9876543210' // different value for each user
    }
};

var cognitoidentity = new AWS.CognitoIdentity();
cognitoidentity.getOpenIdTokenForDeveloperIdentity(params, function(err, data) {
    if (err) {
        console.log(err, err.stack); // an error occurred
    }
    else {
        console.log(data);           // successful response
    }
});

服務器結果：

IdentityId: "ap-northeast-2:5cf7f3cd-b370-416b-bed8-f7f8c7aXXXXX"
Token: "eyJra.....sL8bg"

在瀏覽器上：

AWS.config = new AWS.Config({
    region: 'ap-northeast-2'
});

var params = {
    IdentityId: 'ap-northeast-2:5cf7f3cd-b370-416b-bed8-f7f8c7aXXXXX',      //Received from server
    CustomRoleArn: 'arn:aws:iam::356127965XXX:role/XXXXX_Customer',
    Logins: {
        'com.abc.xyz': '9876543210'
    }
};

var cognitoidentity = new AWS.CognitoIdentity();
cognitoidentity.getCredentialsForIdentity(params, function(err, data) {
    if (err) {
        console.log(err, err.stack); // an error occurred
    }
    else {
        console.log(data);           // successful response
    }
});

瀏覽器結果：

Please provide a valid public provider

身份池配置

Answer 1

基於這篇文章 ，我在瀏覽器部分進行了以下更改

AWS.config.credentials = new AWS.CognitoIdentityCredentials({
    IdentityId: 'ap-northeast-2:5cf7f3cd-b370-416b-bed8-f7f8c7aXXXXX',      //Received from server
IdentityPoolId: 'ap-northeast-2:a383cb2e-e302-4ff6-8d8f-70e3185XXXXX',
    Logins: {
        'cognito-identity.amazonaws.com': '9876543210'
    }
});

AWS.config.credentials.get(function(err, data) {
    if (err) {
        console.log(err); // an error occurred
    }
    else {
        console.log(data);           // successful response
    }
});

AWS.config.credentials

現在我能夠收到包含accessKeyId，expireTime，secretAccessKey和sessionToken的響應

我意識到這是一個老帖子，但是如果有人遇到這個問題，我相信如果你改變了，你的第一種方法會有效：

Logins: {
    'com.abc.xyz': '9876543210'
}

至

Logins: {
    'cognito-identity.amazonaws.com': "eyJra.....sL8bg"
}

我覺得沒有使用您在步驟1中生成的令牌的任何解決方案都是不完整的。
