javascript - Safari 中 Express 服务器响应数据中的 HTTP header

Question

我的 Angular 应用程序正在从 ui-router 解析调用我的 API:

...
$stateProvider
    .state('gallery',{
        abstract: true, 
        templateUrl: 'components/gallery/gallery.html'
    })
    .state('gallery.views', {
        url: "/{gallery:shades-of-gray|color}",
        views: {
            'left@gallery': {
                templateUrl: 'components/gallery/partials/gallery-slider.html',
                controller: 'SliderController'
            },
            'right@gallery': {
                templateUrl: 'components/gallery/partials/gallery-img.html',
                controller: 'GalleryImgController'
            }
        },
        resolve: {
            apiFactory: 'apiFactory',
            drawings: function(apiFactory, $stateParams){
                var param = $stateParams.gallery === 'color' ? 'color' : 'bw';
                return apiFactory.getImageUrls(param);
            }
        }
    });
...

我的 ApiFactory 只是进行 API 调用并解决 promise :

apiFactory.getImageUrls = function(gallery){
    if (gallery === undefined)
        var gallery = 'all';

    return $http({
        method: 'GET',
        url: API_URL + '/drawings/' + gallery,
    }).then(function(response){
        return response.data.gallery;
    });
};

我的两个 Controller 使用我的解析注入(inject)的数据:

.controller('SliderController', function($scope, drawings){
    $scope.drawings = drawings;
    ...
}
controller('GalleryImgController', function($scope, drawings){
   $scope.currentDrawing = drawings[0];
   ...
}

在 Safari 中，我等待 120 秒来解决 $http promise ，此时我会看到带有正确状态代码、 header 等的响应。但是(与Chrome 中的 Firefox)，response.data 是包含 HTTP header 的字符串:

我无法可靠地解析它(因为我将有一个带有一些响应的 Authorization header )。是什么赋予了？为什么 Safari 上会出现此问题？我该怎么办？

如果有帮助，这里是响应请求的 Express 代码:

...
getDrawingSet(gallery, (err, drawings) => {
    if (err)
        return next(err);
    let ret = {};
    ret["gallery"] = drawings;
    res.status(httpStatus[200]).json(ret);
});
...

其中 drawings 只是一个 JSON 对象数组。谢谢。

In Safari, I wait 120 seconds for the $http promise to resolve, at which point I see my response with proper status code, headers etc. However (unlike Firefox in Chrome), response.data is a string containing the HTTP headers:

HTTP/1.1 OK unknown

-> 这不是有效的 HTTP response header .

6.1 Status-Line

The first line of a Response message is the Status-Line, consisting of the protocol version followed by a numeric status code and its associated textual phrase, with each element separated by SP characters. No CR or LF is allowed except in the final CRLF sequence.

   Status-Line = HTTP-Version SP Status-Code SP Reason-Phrase CRLF

应该是:

HTTP/1.1 200 OK

也许 Safari 不接受此作为 header 并将 header 数据推送到响应？或者您在此之前收到其他 header 吗？
