1.AJAX发送一个请求
2.node的server是否能获取响应.
    注意:发送请求的格式.


爬坑1:当最简单设置ajax格式时候,报错.
     $.ajax({
                url: 'http://127.0.0.1:1000/',
                success: function (data) {
                    console.log('Success: ')
                },
            });
    Failed to load http://127.0.0.1:1000/: The 'Access-Control-Allow-Origin' header has a value 'http://127.0.0.1' that is not equal to the supplied origin. Origin 'http://localhost:63342' is therefore not allowed access.
    解析:
    浏览器默认禁止跨域.
    为设置Access-Control-Allow-Origin的url

爬坑2:node.js提示.
