解决“No 'Access-Control-Allow-Origin' header is present on the requested resource”

1. 问题描述

在js中使用ajax请求在网页控制台下打印以下错误信息：

XMLHttpRequest cannot load http://192.168.2.46:8000/account/getjson/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access.

本人的ajax代码如下

var jsontree = [];
$.ajax({
    url: "http://192.168.2.46:8000/account/getjson/",
    type: "GET",
    dataType: 'JSON',
    success: function(result){
        jsontree = result;
    }
});1
