let urlArray=queryURLParameter(location.href);
            let urlCode=urlArray.code;//通過url獲取到的code
            let authCode=getSession("authCode");//通過session獲取code
            if(!urlCode){
                setSession("authCode",urlCode);
                window.history.back();
            }
            if
 
(!urlCode&&!authCode){
                let authUrl=api.authUrl.replace("REDIRECTURL",encodeURIComponent(location.href));//授權回撥地址
                console.log(authUrl);
