我开始开发在Facebook，Twitter和Pinterest上分享编辑过的图像。
我们有一个学习管理系统（LMS），它是使用Angularjs开发的，Angularjs是一个使用Laravel开发的前端网站和一组API。
用户登录LMS后，用户可以在Facebook，Twitter和Pinterest上共享推荐代码。要共享引荐代码，我们使用图像。每次我们将用户的推荐代码添加到图像并共享它。图像处理由前端站点完成。因此，我正在设置前端站点视图的URL，该URL使用引用代码创建图像并使用它在社交媒体上共享。
共享代码如下（LMS）

<share-referrer></share-referrer>
skApi.directive('shareReferrer', function ($window, $cookies, skApiService, $location, $http) {
return {
restrict: 'E',
link: function (scope, element, attrs) {
scope.share_referral_url = "";
scope.share_pinterest_referral_url = "";
scope.share_referral_pinterest_image_url = "";
$http({
method: 'POST',
url: skApiService.getApiUrl('lms')+'/referrals/get-user-referral-details',
headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' }
}).then(function successCallback(respond) {
// this callback will be called asynchronously
// when the response is available
if (respond.data.success == true){
scope.refer_first_name = [];
scope.refer_first_name_email = [];
scope.share_referral_url = respond.data.share_referral_url;
scope.share_pinterest_referral_url = respond.data.share_pinterest_referral_url;
scope.referral_code = respond.data.data.code;
scope.share_referral_pinterest_image_url = respond.data.share_referral_pinterest_image_url;
console.log(scope.share_referral_url);
}else if (respond.data.success == false){
scope.hide_message = false;
scope.message_section_class = "alert alert-danger";
scope.error_message = respond.data.message;
}
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
scope.$watch(scope.share_referral_url ,function(newValue, oldValue){
console.log("share referral url ", newValue, oldValue);
});
/*Share on pinterest*/
scope.pinIt = function(){
var pinterest_url = scope.share_pinterest_referral_url+"&type=pinterest";
$http({
method: 'GET',
url: pinterest_url,
headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' }
});
//This code from pinterest
PinUtils.pinOne({
'url': pinterest_url,
'media': scope.share_referral_pinterest_image_url,
'description': 'Next stop: Pinterest!'
});
//End pinterest
};
},
scope: {
share_referral_url: '@',
share_referral_pinterest_image_url: '@',
referral_code: '@',
},
templateUrl: 'directives/social-media-share.html'
};

根据类型GET变量，我们在前laravel站点中识别一种社交媒体并向图像添加文本。我们在相关的视图文件中设置了该图像。有三个视图文件。

这些共享功能正常运行。在每个共享帖子中，这些社交媒体都设置了我从LMS共享的URL。但Facebook添加了fbid的URL结尾。但是其他人（twitter和Pinterest）没有设置参数来识别它。是否有参数或反正来识别它？
正如@ 04FS所说，我检查了laravel控制器中请求对象的'HTTP_REFERER'服务器变量，以识别referer如下
$data = $request->all();
$http_referrer = parse_url($request->server('HTTP_REFERER'));
//For facebook
if( isset($data['fbclid'])){
return redirect('/?return='.$data['fbclid']."&type=".$data['type']."&referral_code=".$data['referral_code']);
}
//For Twitter
if(isset($http_referrer['host']) && $http_referrer['host'] != NUll && $http_referrer['host'] == 't.co'){
return redirect('/?return=twitter&type='.$data['type']."&referral_code=".$data['referral_code']);
}
//For Pinterest
if( isset($http_referrer['host']) && $http_referrer['host'] != NUll && $http_referrer['host'] == 'www.pinterest.com'){
return redirect('/?return=pinterest&type='.$data['type']."&referral_code=".$data['referral_code']);
}
