AJAX方式发送远程请求报错：No 'Access-Control-Allow-Origin' header

AJAX GET方式发送远程请求,chrome开发者工具console中报错：XMLHttpRequest cannot load http://www.shikezhi.com/ajax/getData Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access.

解决办法：使用jsonp格式， ajax请求参数dataType:'JSONP'，如：

$.ajax({

   method: "GET",

   url: "http://www.shikezhi.com/ajax/getData",

   dataType: 'JSONP',//加入这个选项即可

   data:params,

   jsonpCallback: "jsonpcallback",

   beforeSend: function (xhr) {

   },

   success: function (response) {

  console.log(response);

   },

   error: function (jqXHR, textStatus, errorThrown) {

   }

});
