需要使用AWS Cognito SDK，执行以下步骤：

1.创建CognitoUser对象：

var poolData = {
    UserPoolId: '...', // your user pool id here
    ClientId: '...' // your app client id here
};
var userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
var userData = {
    Username: 'USERNAME',
    Pool: userPool
};
var cognitoUser = new AmazonCognitoIdentity.CognitoUser(userData);

2.检查CognitoUser对象的SoftLock状态：

cognitoUser.checkAuthentication = function(callback) {
    var cognitoUser = this;
    if (cognitoUser && cognitoUser.signInUserSession && cognitoUser.signInUserSession.isValid()) {
        callback(cognitoUser);
    } else {
        cognitoUser.getSession(function(err, session) {
            if (err) {
                alert(err);
                return;
            }
            callback(cognitoUser);
        });
    }
};

3.创建软锁定解除请求：

var params = {
    AccessToken : "...", // your access token here
    UserPoolId : "...", // your user pool id here
    Username : "USERNAME" // the user you want to unlock here
};
var cognitoidentityserviceprovider = new AWS.CognitoIdentityServiceProvider();
cognitoidentityserviceprovider.adminUserUnblock(params, function(err, data) {
    if (err) console.log(err, err.stack); // an error occurred
    else     console.log(data);           // successful response
});
