php - 尝试将数据发送到本地主机 :8000 from localhost 时 ajax 调用不起作用

Question

当我尝试从 php (localhost) 到 django (localhost:8000) 进行 AJAX 调用时，它会抛出以下错误。

XMLHttpRequest cannot load http://localhost:8000/project/login/uid=bimt;token=KAMWMS151UWP67Q. Origin http://localhost is not allowed by Access-Control-Allow-Origin.

$(document).on('click', '.login', function(event) {
    var username = $('#username').val();
    var token = $('#token').val();
    $.ajax({
       type: "POST",
       url: "http://localhost:8000/project/login/uid=" + username + ";token=" + token,
       success: function (html) {
         alert(html);
        }
     });
});

因为端口不一样，所以被认为是跨源请求。您必须在请求的脚本中设置 Access-Control-Allow-Origin header 。

或者，专门针对 django:
