1.1 商户扫用户统一下单接口
<h2>商户扫用户统一下单接口</h2>
<p><strong>接口地址</strong>:<code>/pay/api/1.0/b2cUnifiedOrder</code></p>
<p><strong>请求方式</strong>:<code>POST</code></p>
<p><strong>请求数据类型</strong>:<code>application/json</code></p>
<p><strong>响应数据类型</strong>:<code>application/json</code></p>
<p><strong>接口描述</strong>:</p>
<p><code>步骤1：</code>用户和商户确认订单金额
<code>步骤2：</code>用户向商户展示支付二维码(微信、支付宝等)
<code>步骤3：</code>商户使用扫码枪，扫描用户二维码并提交到招联扫码，并实时返回支付结果</p>
<p><code>注：</code>条码支付存在需要用户输入支付密码的场景(实时返回用户支付中)，是否需要输入支付密码，与支付宝、微信的风控规则有关。此时需要商户主动发起查询来确定最终的订单状态。(建议：交易发起5S以后开始查询。查询间隔5S以上)</p>
