How to set up JIRA API to allow cross-origin HTTP request

I want to integrate my application with JIRA, so when I submit a request to the JIRA server, it returns an error saying " XMLHttpRequest cannot load https: // ********* / rest / api / 2 / project. Pre-flight request response fails access control check: the requested resource does not have an "Access-Control-Allow-Origin" header. '

This is my code

    $http({
        method: "GET",
        url: "https://***********/rest/api/2/project",
        headers: {
            'Content-Type': 'application/json',
            'Access-Control-Allow-Origin': 'https://duosoftware.atlassian.net',
            'Access-Control-Allow-Methods': 'GET, POST, DELETE, PUT, OPTIONS',
            'Access-Control-Allow-Headers':'X-Requested-With, Content-Type, X-Codingpedia,Authorization'
        },
        dataType: "jsonp",
    }).then(function mySuccess(response) {
        $scope.myWelcome = response.data;
        console.log(response.data);
    }, function myError(response) {
        $scope.myWelcome = response.statusText;
        console.log(response.statusText);
    });

};
