axios请求之前带上全局参数

// 测试地址
const API = {
    local:'XXXXX',
    online:'XXXXX',       
};

//axios固定参数，定义全局变量
//方法一：
var login_key,uid;
function getUrlParam(name){
    var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
    var r = window.location.hash.substr(1).match(reg);
    if (r!=null) return unescape(r[2]); return null;
}

function getQueryVariable(val) {
    var query = window.location.hash.substring(1);
    var vars = query.split("&");
    if( val == 'uid'){
        for (var i=0;i<vars.length;i++) {
            var rps = vars[0];
            return rps.split("=")[1];
        }
        return(false);
    }
}
login_key = getUrlParam('login_key');
uid = getQueryVariable('uid');

//方法二：
var login_key,uid;
function request(paramName) {
    var paramValue = "";
    var params = window.location.href.split('?')[1];
    if (params == null || params == "")
        return paramValue;
    var arr = params.split('&');
    if (arr.length >= 1) {
        for (var i = 0; i < arr.length; i++) {
            var name = arr[i].substring(0, arr[i].indexOf("="));
            if (name == paramName) {
                var begin = arr[i].indexOf("=");
                var end = arr[i].length;
                paramValue = arr[i].substring(begin + 1, end);
                break;
            }
        }
    }
    return paramValue;
}

login_key = request('login_key');
uid = request('uid');
