从节点+ Express重定向时的挂起类型

Question

I am sending POST request from client using JQuery and redirecting to root using node.js. But in my developer console i am getting the status : 302 (temporarily) and type : Pending

Client Code:

$.ajax({ 
    type: "POST",
    dataType: "json",
    data: JSON.stringify({
            username_var:username_var,
            password_var:password_var          
        }),
    url: "/login",
    success: function(data){ 
        alert(data)       
        console.log(data);
        alert(data.name);
    }
});

Server Code:

if (req.method == 'POST'){
    console.log("[200] " + req.method + " to " + req.url);
    req.on('data', function(chunk) {
        console.log("Received body data:");
        console.log(chunk.toString());
        var userLoginObject = JSON.parse(chunk);
        console.log(userLoginObject.username_var);
        console.log(userLoginObject.password_var);
        var status = {
            name: "CHATEAU DE SAINT COSME",
            year: "2009",
            grapes: "Grenache / Syrah",
            country: "France",
            region: "Southern Rhone",
            description: "The aromas of fruit and spice...",
            picture: "saint_cosme.jpg"
        };
        res.redirect("/");
        res.end();
      // //res.send(status);
      // res.writeHead(301, {"Location": "http://localhost:8000/"});
      // res.end("Test");
    });

Unless things have changed (over the last year or so), redirect from the server (using expressJS) will not work for a POST operation from the client. You can redirect from the client side using something like this (essentially, when you need to redirect, send a certain message that you can check on in the callback handler for the post operation):

$.post('/login',function(){  //window.location to be called upon message from server
 window.location = 'page to redirect to';  //you can check for a certain message from server
});

In your case, it will be this part:

    success: function(data){ 
 window.location = 'page to redirect to';
}

Hope it helps.
