jQuery AJAX错误：跨域请求被阻止

Question

我正在尝试向运行在localhost上的API发送ajax请求，但出现错误

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at 
http://127.0.0.1:9100/api/banks. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

HTML页面的运行位置：http://localhost/jqmob/

尽管相同的代码在邮递员上工作正常，但如何解决此问题？

var form = new FormData();
form.append("lang", "en");

var settings = {
  "async": true,
  "crossDomain": true,
  "url": "http://127.0.0.1:9100/api/banks",
  "method": "POST",
  "headers": {
    "Cache-Control": "no-cache",
    "Postman-Token": "b246c9ad-ce2d-4e39-bbef-5df0af6476e0"
  },
  "processData": false,
  "contentType": false,
  "mimeType": "multipart/form-data",
  "data": form
}

$.ajax(settings).done(function (response) {
  console.log(response);
});

在本地主机的HTML页面中，我使用jQuery 1.11.3

在.htaccess中的API应用中

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>
