props.preCreate 大兄弟这个函数有坑

[bughp]

版本信息："version": "1.1.9"
函数：props.preCreate = function (opts) {
var biz_content = {
out_trade_no: opts.outTradeId,
subject: opts.subject,
total_amount: opts.amount,
body: opts.body,
timeout_express: opts.timeout,
goods_detail: opts.goodsDetail,
extend_params: opts.extendParams,
enable_pay_channels: opts.enablePayChannels,
disable_pay_channels: opts.disablePayChannels
};

var params = this.makeParams('alipay.trade.precreate', biz_content);
params.notify_url = this.notifyUrl;
// params.return_url = opts.return_url;

var body = utl.processParams(params, this.rsaPrivate, this.signType);

//缺少步骤
return utl.request({
    method: 'GET',
    url: (this.sandbox? alipay_gate_way_sandbox : alipay_gate_way) + '?' + body
});
//原步骤已注释
// return utl.processParams(params, this.rsaPrivate, this.signType);

};

望修复
