AWS Cognito Identity JS：忘记/记住/不记得设备 [英] AWS Cognito Identity JS: Forget/Remember/Do Not Remember Device

问题描述

我正在使用AWS Cognito Identity JS SDK（ https：// github .com / aws / amazon-cognito-identity-js ），而我试图设置一些按钮来测试 setDeviceStatusRemembered ， setDeviceStatusNotRemembered 和 forgetDevice 功能，但我不断收到错误消息：

I'm working with the AWS Cognito Identity JS SDK (https://github.com/aws/amazon-cognito-identity-js) and I'm trying to set up a few buttons to test the setDeviceStatusRemembered, setDeviceStatusNotRemembered, and forgetDevice functionality but I keep getting an error saying:

MissingRequiredParameter：在参数中缺少必需的键'DeviceKey'

以下是其中一个功能的实现：

Here is an implementation of one of the functions:

forgetDevice = function(){

var cognitoUser = userPool.getCurrentUser();

if (cognitoUser != null) {
    cognitoUser.getSession(function(err, session) {
        if (err) {
            alert(err);
            signOut();
            return;
        }

        console.log('session validity: ' + session.isValid());

        cognitoUser.forgetDevice({
            onSuccess: function (result) {
                console.log('call result: ' + result);
            },
            onFailure: function(err) {
                alert(err);
            }
        });
    });
  } 
}

如果我更改如下功能：

forgetDevice = function(cognitoUser){
    cognitoUser.forgetDevice({
        onSuccess: function (result) {
            console.log('call result: ' + result);
        },
        onFailure: function(err) {
            alert(err);
        }
    });
}

然后我从 cognitoUser.authenticateUser调用该函数 成功回调函数，将 cognitoUser 作为参数传递给 forgetDevice 函数在所有功能上都工作完美。

and I call the function from the cognitoUser.authenticateUser success callback function, passing cognitoUser as argument into the forgetDevice function above everything works perfectly.

从第一个对象中查看 session 对象实现，看来 session 对象不包含 DeviceKey 属性，因此 cognitoUser.forgetDevice （）调用失败。

From looking at the session object in the first implementation it appears that the session object does not contain the DeviceKey property so the cognitoUser.forgetDevice() call fails.

我要弄清楚的是，我应该只调用 setDeviceStatusRemembered吗？ ， setDeviceStatusNotRemembered 和 forgetDevice 函数在登录时有效，或者我应该能够调用它们在我的申请表中有任何时间？希望这是有道理的。任何帮助将不胜感激。谢谢！

What I'm trying to figure out is, should I just be calling the setDeviceStatusRemembered, setDeviceStatusNotRemembered, and forgetDevice functions on login, or should I be able to call them any time within my application? Hopefully that makes sense. Any help would be greatly appreciated. Thanks!

推荐答案

此帮助吗？

请注意，如果设备使用要求用户选择加入的设置为用户池启用了跟踪，您需要实现onSuccess（result，userConfirmationNecessary）回调，收集用户输入并调用setDeviceStatusRemembered记住设备或setDeviceStatusNotRemembered记住设备。

Note that if device tracking is enabled for the user pool with a setting that user opt-in is required, you need to implement an onSuccess(result, userConfirmationNecessary) callback, collect user input and call either setDeviceStatusRemembered to remember the device or setDeviceStatusNotRemembered to not remember the device.

还可以尝试调用getCachedDeviceKeyAndPassword填充CognitoUser对象中的deviceKey吗？

Also can you attempt calling getCachedDeviceKeyAndPassword to populate the deviceKey in the CognitoUser object?
