JS之获取tocken

1、从cookie中获取

function getToken(){
//cookie是一个字符串
    var strcookie = document.cookie;//获取cookie字符串
    var arrcookie = strcookie.split("; ");//分割
    //遍历匹配
    for ( var i = 0; i < arrcookie.length; i++) {
        var arr = arrcookie[i].split("=");
        if (arr[0] == "token"){
            return arr[1];
        }
    }
    return "";
}

2、从url获取

function getTokenByUrl(){
	var token = GetQueryString("token");
	return token;
} 
 
//获取url参数
function GetQueryString(name)
{
    var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
    var r = window.location.search.substr(1).match(reg);
    if(r!=null)return  unescape(r[2]); 
    return null;
}
