如何使用 Node/Express 从客户端调用 ajax get 请求？

Question

I have a file shuffleRoute.js where I define this:

router.get("/shuffle?jokers=false", function (req, res) {
   cards['a','b','c'];
   let shuffledCards =  _.shuffle(cards);

    res.status(200).send(shuffledCards);

});

I have an index.js where I define:

app.get("/v1/game", require("./routes/shuffleRoute.js"));

I have a game.html where onload I need to do an ajax request to get the shuffled cards. How do I do that?

doing this

  $.get( "/v1/game", function(res) {
        console.log(res);
    });

does not work.

I am getting this error:

jquery-2.2.4.min.js:4 GET localhost:8080/v1/game 500 (Internal Server Error) –

I was using morgan to log things in the server which was incorrectly done.

However, commenting that out gives me this error.

jquery-2.2.4.min.js:4 GET http://localhost:8080/v1/game 404 (Not Found)

May be wrong but i see routes problem here.

When you define routes for express use app.use

var myRoute = require('PathToYourRouteFile');

app.use("/v1/game", myRoute);

In route file. Im asuming you use express router you need to define something like this

youRuoterName.get('/', function(req, res, next) { })

This request will be succes when you go to localhost/v1/game .

If you want another one just do

youRuoterName.get('/shuffle', function(req, res, next) { })

Which will be succes when you go to /v1/game/shuffle .

In your example i see only one route /v1/game/shuffle which clearly not match /v1/game and im not even sure that rest of code works as expected.

So please read docs carefuly http://expressjs.com/en/4x/api.html#router.route and all should work.

Hope this helps.
