jQuery Ajax数据未显示

Question

In the following ajax request, I am sending a request to my node server to do some work on the file with name fileName.

Ajax

$.ajax({
    type: "POST",
    data: {'imageFileName': fileName},
    contentType: "json",
    url: '/myRoute',
    success: function(data){
        if(!data){
            errorMessage();
        }
        else{
            display(data);
        }
    }
})

Router

router.post('/myRoute', function(req, res){
    console.log(req.imageFileName) //Undefined
    res.end();
})

However, when I log the request on the server-side, I get a giant object without the fileName. Given that the request is named req, req.imageFileName yields undefined. What am I doing wrong such that I can't access fileName on the server side?

Try removing quote in data. Also cross check oncec what is in the filename.

$.ajax({
    type: "POST",
    data: {imageFileName: fileName},
    contentType: "json",
    url: '/myRoute',
    success: function(data){
        if(!data){
            errorMessage();
        }
        else{
            display(data);
        }
    }
})
