angular.js - The same execution request using $http will prompt a cross-domain request, but using jquery's ajax will be normal.

Question

{code...} {code...} Shouldn't these two have exactly the same meaning? Why can it be executed successfully when using ajax, but when using $http, it prompts a cross-domain error?

postCfg = {
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
  },
  transformRequest: function(data) {
    return $.param(data);
  }
}

app.config([
  '$httpProvider',
  function($httpProvider) {
    $httpProvider.defaults.useXDomain = true;
    delete $httpProvider.defaults.headers.common['X-Requested-With'];
   }
]}

$http.post(url, {}, postCfg)

The method I found, the speed test was successful

Angular uses jsonp cross-domain, of course, the premise is that your server returns jsonp format.

$http.jsop(url).success(fn).error(fn);
