When you use axios to call the background interface, baseurl itself becomes localhost,. How to change it?

my axios function:
import axios from "axios"
import Qs from" qs"
export default {

post: function (url, data) {
    axios.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
    let config = {
        //axios.get(url,config);urlconfigurl
        url: url,

        // 
        method: "post", // default
        // url
        baseURL: "https://39.104.91.74:8080/",

        transformRequest: [function (data) {
            // form-dataQsaxios
             data = Qs.stringify({});
             return data;
             console.log(data)
        }],

        transformResponse: [function (data) {
            // 

            return data;
        }],

        // 
        headers: {
            "Authorization": sessionStorage.obj,
            "Content-Type":"application/x-www-form-urlencoded;charset=UTF-8"
        },

        //parameter
        params: {
            timestamp: Date.parse(new Date()) / 1000
        },

        withCredentials:true,

        //postaxios.post(url,{},config);
        data: data,

        //
        timeout: 5000,
        //
        responseType: "json", // default
    }
    return axios.post(url, data, this.config)
}

}

call the interface on the page:

selectpriceDate = () = > {

    let url="api/notice/list"
    let form={
        pageNo: "1",
        pageSize: "12",
        type:null
    }
    ajax.post(url, form)
        .then(function (res) {
            console.log(res)
        })
        .catch(function (err) {
            console.log(err)
        })
}
