Question

当我使用http://localhost:3000/buyersearch运行此路线时，我得到＆＃34;请输入买方识别号码＆＃34;如预期的那样。但是当我跑步的时候 http://localhost:3000/buyersearch?buyerID=2447它应该使用我制作的ejs文件输出。但相反，我得到了＃34;没有找到带有该ID号的订单＆＃34;。 2447！它存在于我的数据库中。为什么它没有恢复？

由于

       **Here's my JSON**

       {"buyerID" : 2447,
        "name" : {
                "f" : "Jai",
                "s" : "Kishner"
        },
        "gender" : "Male",
        "birthDate" : "1996-08-13",
        "student" : true,
        "appOS" : "Android"}

继承我的buyerSearch.js以查询我正在做的

var express = require('express');
var router = express.Router();
var mongodb = require('mongodb');
var mongoClient = mongodb.MongoClient;
var url = 'mongodb://localhost:27017/WishList';


//http://localhost:3000/buyersearch?buyerID=2447


//buyerIDSearch
router.get('/', function (req, res) {
    var buyerID = req.query.buyerID;

    if (!buyerID) {
        res.render('error', {message: "Please enter an Buyer Identification Number", error: {status: "", stack: ""}});
    } else {
        mongoClient.connect(url, function (err, db) {
            if (err) {
                res.render('error', {message: "Failed to connect", error: {status: "", stack: ""}});
            } else {
                var WishListDB = db.collection('orders');
                WishListDB.find({"_buyerID": (buyerID)}).toArray(function (err, result) {
                    if (err || !result || result.length == 0) {
                        res.render('error', {
                            message: "No order found with that ID number",
                            error: {status: "", stack: ""}
                        });
                    } else {
                        res.render('order', {
                            order: result[0]
                        })
                    }

                });

            }

        })
    }

});

module.exports = router;


**Heres my buyerSearch.ejs file that I'm using to output the buyer ID once entered**

<!DOCTYPE html>
<html>
<head>
  <title></title>
  <link rel='stylesheet' href='/stylesheets/style.css' />
</head>
<body>
<h1></h1>
<p>Welcome</p>

<p><%buyerSearch.buyerID %></p>
</body>
</html>

Answer 1

对您的收藏集的查询应使用"buyerID"而不是"_buyerID"，如下所示：

WishListDB.find({"buyerID": buyerID}).toArray()
