use webpack to open the front page on the local localhost:8080 port
proxy is configured like this:

    devServer: {
        port: 8080,
        contentBase: "./dist",
        proxy: {
            "/abc": {
                target: "http://122.79.10.259:8080"
            }
        }
    },

the code that uses the ajax request on the page looks like this:

    $.ajax({
        url: "/abc/signup/video",
        type: "get"
    }).done(res => {

    }).fail(err => {

    })

at this point, the browser still asks for http://localhost:8080/abc/signup/video, instead of http://122.79.10.259:8080/abc/signup/video
, ask the gods to help solve the problem.
