Http工具类

    1.get 方式访问数据接口
    2.post 方式范围数据接口

function Request(e) {
    return new Promise(function (t, i) {
        var n = new XMLHttpRequest;
        n.open(e.method || "GET", e.url), e.headers && Object.keys(e.headers).forEach(function (t) {
            n.setRequestHeader(t, e.headers[t]);
        }), n.onload = function () {
            n.status >= 200 && n.status < 300 ? t(n.response) : i(n.statusText);
        }, n.onerror = function () {
            return i(n.statusText);
        }
        n.send(JSON.stringify(e.body));
    })
}

// 获取商品信息
