内容图文

我有一个简单的AngularJS应用程序,允许用户搜索Flickr照片.问题出在IE中我在调用Flickr API时得到以下消息：

此页面正在访问不受其控制的信息.这带来了安全风险.你想继续吗？

如果我单击是,该应用程序将工作并加载相关照片.但是,在Chrome和Firefox中,我没有收到任何消息,也没有任何反应 – 没有加载照片.

这是代码：

function PhotoController($scope, photoData) {
    $scope.thumbSize = 'small';
    $scope.setThumbSize = function (size) { $scope.thumbSize = size; };

    $scope.submitSearch = function getPhotos() {
        $scope.photos = [];
        $scope.items = [];

        photoData.getAllItems($scope.searchKeyword).then(function (data) {
            var parsedData = angular.fromJson(data);
            $scope.items = parsedData.photos.photo;

            for (var i = 0; i < $scope.items.length; i++) {
                var photo = $scope.items[i];
                $scope.photos.push({ title: photo.title, thumbUrl: ' http://farm' + photo.farm + '.staticflickr.com/' + photo.server + '/' + photo.id + '_' + photo.secret + '_m.jpg' });
            }
        },
        function (errorMessage) {
            $scope.error = errorMessage;
        });

    };
}

angular.module('photoApp').factory('photoData', function ($http, $q) {
    return {
        getAllItems: function (keyWord) {
            //Creating a deferred object
            var deferred = $q.defer();
            var apiUrl = 'http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=myAPIkey&tags=' + keyWord + '&format=json&nojsoncallback=1';

            //Calling Web API to fetch pics
            $http.get(apiUrl).success(function (data) {
                deferred.resolve(data);
            }).error(function () {
                deferred.reject("An error occured while fetching photos");
            });
            return deferred.promise;
        }
    }
});

如何摆脱消息并使其在Chrome / Firefox中运行？

更新：我基于joakimbl的plunker将代码更改为以下,现在它在Chrome和FF中运行,但IE仍然会抛出警告消息.

var app = angular.module("photoApp", []);

app.controller('PhotoController', function ($scope, photoData) {
    $scope.thumbSize = 'small';
    $scope.setThumbSize = function (size) { $scope.thumbSize = size; };

    $scope.submitSearch = function getPhotos() {
        $scope.photos = [];
        $scope.items = [];

        photoData.getAllItems($scope.searchKeyword).then(function (data) {
            var parsedData = angular.fromJson(data);
            $scope.items = parsedData.photos.photo;

            for (var i = 0; i < $scope.items.length; i++) {
                var photo = $scope.items[i];
                $scope.photos.push({ title: photo.title, thumbUrl: ' http://farm' + photo.farm + '.staticflickr.com/' + photo.server + '/' + photo.id + '_' + photo.secret + '_m.jpg' });
            }
        },
        function (errorMessage) {
            $scope.error = errorMessage;
        });
    };
});

app.config(function ($httpProvider) {
    delete $httpProvider.defaults.headers.common['X-Requested-With'];
});

app.factory('photoData', function ($http, $q) {
    return {
        getAllItems: function (keyWord) {
            //Creating a deferred object
            var deferred = $q.defer();
            var apiUrl = 'http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=84ad829261f6347dbfc4bf23fc1afdbd&tags=' + keyWord + '&format=json&nojsoncallback=1';

            //$http.defaults.useXDomain = true;
            //delete $http.defaults.headers.common['X-Requested-With'];

            //Calling Web API to fetch pics
            $http.get(apiUrl).success(function (data) {
                //Passing data to deferred's resolve function on successful completion
                deferred.resolve(data);
            }).error(function (error) {
                //Sending a friendly error message in case of failure
                deferred.reject("An error occured while fetching items");
            });
            //Returning the promise object
            return deferred.promise;
        }
    }
})

;

解决方法:

X-Requested-With请求标头导致问题 – see this question for more information.以下代码应该解决问题：

angular.module('photoApp').config(function($httpProvider){
  delete $httpProvider.defaults.headers.common['X-Requested-With'];
});
