REST ガンマン

JAX-RS (Jersey) でRESTインタフェースを実現しました。

type=html/text/json(2種類)/jsonp のパターンを試しました。

クライアント記述 (jQuery ($.ajax) )

//    const endpoint = "https://35.225.1.11:8443/GunmanREST/rest/gunclock/jsonp/26";   //OK

    $.ajax({
        type: 'GET',
        url: endpoint,
        dataType: 'jsonp',
        data: {
        },
        success: out => {
//            alert(out.message);
            showJson(out.message);
            gunClockAsync(out.message);
        }
