// 此处的attach不能为空值 否则微信提示签名错误 
  order: function(attach, body, mch_id, openid, bookingNo, total_fee, notify_url) { 
    var deferred = Q.defer(); 
    var appid = config.member_config.appid; 
    var nonce_str = this.createNonceStr(); 
    var timeStamp = this.createTimeStamp(); 
    var url = "https://api.mch.weixin.qq.com/pay/unifiedorder"; 
    var formData = "<xml>"; 
    formData += "<appid>" + appid + "</appid>"; //appid 
    formData += "<attach>" + attach + "</attach>"; //附加数据 
    formData += "<body>" + body + "</body>"; 
    formData += "<mch_id>" + mch_id + "</mch_id>"; //商户号 
    formData += "<nonce_str>" + nonce_str + "</nonce_str>"; //随机字符串，不长于32位。 
    formData += "<notify_url>" + notify_url + "</notify_url>"; 
    formData += "<openid>" + openid + "</openid>"; 
    formData += "<out_trade_no>" + bookingNo + "</out_trade_no>"; 
    formData += "<spbill_create_ip>61.50.221.43</spbill_create_ip>"; 
    formData += "<total_fee>" + total_fee + "</total_fee>"; 
    formData += "<trade_type>JSAPI</trade_type>"; 
    formData += "<sign>" + this.paysignjsapi(appid, attach, body, mch_id, nonce_str, notify_url, openid, bookingNo, '61.50.221.43', total_fee, 'JSAPI') + "</sign>"; 
    formData += "</xml>"; 
    var self = this; 
    request({ 
      url: url, 
      method: 'POST', 
      body: formData 
    }, function(err, response, body) { 
      if (!err && response.statusCode == 200) { 
        console.log(body); 
        var prepay_id = self.getXMLNodeValue('prepay_id', body.toString("utf-8")); 
        var tmp = prepay_id.split('['); 
        var tmp1 = tmp[2].split(']'); 
        //签名 
        var _paySignjs = self.paysignjs(appid, nonce_str, 'prepay_id=' + tmp1[0], 'MD5', timeStamp); 
        var args = { 
          appId: appid, 
          timeStamp: timeStamp, 
          nonceStr: nonce_str, 
          signType: "MD5", 
          package: tmp1[0], 
          paySign: _paySignjs 
        }; 
        deferred.resolve(args); 
      } else { 
        console.log(body); 
      } 
    }); 
    return deferred.promise; 
  }, 
 
  //支付回调通知 
  notify: function(obj) { 
    var output = ""; 
    if (obj.return_code == "SUCCESS") { 
      var reply = { 
        return_code: "SUCCESS", 
        return_msg: "OK" 
      }; 
 
    } else { 
      var reply = { 
        return_code: "FAIL", 
        return_msg: "FAIL" 
      }; 
    } 
 
    output = ejs.render(messageTpl, reply); 
    return output; 
  }, 
}; 
module.exports = WxPay;

三、在express router中调用wxpay

//微信支付demo 
router.get('/order', function(req, res, next){ 
  var attach = "1276687601"; 
  var body = "测试支付"; 
  var mch_id = "1111111"; ／／商户ID 
  var openid = "111111"; 
  var bookingNo = "201501806125346"; ／／订单号 
  var total_fee = 10; 
  var notify_url = "http://localhost/wxpay/notify"; //通知地址 
  wxpay.order(attach, body, mch_id, openid, bookingNo, total_fee, notify_url).then(function(data){ 
    res.render('wxpay', {args: data}); 
  }); 
});
