Node.js express4.x 登录验证中间件

使用post来登录

  function  nodejs_loging()    {        var  x = new XMLHttpRequest();        x.onreadystatechange =function()        {            if(x.readyState == 4) {                if(x.status == 200) {                    console.log("The server replied with: " + x.responseText);                    txt.text = x.responseText;                }else{                    console.log(x.status)                }            }        };        var xxx =new Object;        var d="test.jpg"        console.log(typeof d)        x.open("POST","http://192.168.0.105:1236/test",true,"admin","123");         x.setRequestHeader("Content-Type","application/x-www-form-urlencoded");        x.send("数据");    }

发送post请求,调用test,服务器接收请求并且检验登录状态,然后处理请求做响应操作,例子中简单返回ok字符串
