我不能使用ajax从我的网站上使用Rest API，其中API和网站的端口不同

I have a Rest API developed in spring boot.It is running on port 9090.I have to consume the api from my website to get some data using angluarjs.The website is hosted in a shared hosting server which port is 80.Now there occurs problem in consuming the API from 80 port to a different port 9090.

I also tried using curl from php there is same issue occurs.

Here is my API : https://****url****:9090/aubwebsite-0.0.1-SNAPSHOT/api/document/alldocuments

AngularJs Controller is :

$scope.getDocuments = function(){
                var search  = {
                    pageNo : 1,
                    studentId:"",
                    studentName:"",
                    rowPerPage:11
                };
                $http({
                    method: "POST",
                    url: 'http://****url****:9090/aubwebsite-0.0.1-SNAPSHOT/api/document/alldocuments',
                    data: $httpParamSerializerJQLike(search),
                    headers: {
                        'Content-Type': 'application/x-www-form-urlencoded'
                    }
                }).then(function(response) {
                    console.log(response.data.documentList);
                    if(response.data.documentList === undefined || response.data.documentList.length == 0){
                        $scope.documents = [];
                    }else {
                        $scope.documents = response.data.documentList;
                        $scope.quantity = response.data.itemQuantity;
                    }
                    console.log($scope.documents,'All documents List');
                    console.log(response.data);
                });
            }

From the above call there is no api call take place.

How to consume an API from website whereas the port of the API and website deployed are different?

You need to implement Cross-Origin Resource Sharing, known as CORS.

At its simplest, implement something like the following as a response to OPTIONS request:

Access-Control-Allow-Origin: http://your-origin-website
Access-Control-Allow-Methods: POST, OPTIONS
Access-Control-Allow-Headers: Content-Type
Access-Control-Max-Age: 86400

However, you claim you have the same issue when using curl from PHP. That shouldn't happen.
