如何在VPN - AngularJS中找到主机名的IP地址

// 在AngularJS控制器中
app.controller('MainCtrl', function($scope, $http) {
    $scope.hostname = 'example.com'; // 替换为你想要查询的主机名
    $scope.ipAddress = '';

    $http.get('https://api.ipify.org?format=json')
        .then(function(response) {
            // 这里假设你有一个可以解析主机名的服务
            var ipifyResponse = response.data.ip;
            $http.get('https://dns.google/resolve?name=' + $scope.hostname)
                .then(function(resolveResponse) {
                    $scope.ipAddress = resolveResponse.data.Answer[0].data;
                }, function(error) {
                    console.error('Error resolving hostname:', error);
                });
        }, function(error) {
            console.error('Error getting public IP:', error);
        });
});
