the console shows values undefined instead of input data
I want to take data from an html file and insert into the mongo database using get method. But I am not able to fetch data from the textbox.
nodejs(index.js)中的代码
const express = require('express');
const path = require('path');
const bodyparser = require("body-parser");
const mongoose = require('mongoose');
const app = express();
app.use(bodyparser());
app.use(bodyparser.urlencoded({
extended: false
}));
app.use(bodyparser.json());
app.set('port', (process.env.PORT || 1000));
mongoose.connect('mongodb://localhost/TrackDB');
var Schema = new mongoose.Schema({
username: String
, pass: String
});
var users = mongoose.model('users', Schema);
app.get("/register", function (req, res) {
var userID = req.userid;
var pwd = req.pwd;
console.log("userid = " + userID + "pass = " + pwd);
new users({
username: userID
, pass: pwd
}).save(function (err, doc) {
if (err) {
res.json(err);
}
else res.send("Successfully Registerd!");
});
console.log("users = " + users);
});
app.get("/", (req, res) => {
res.sendFile(path.join(__dirname, './public/index.html'));
});
app.listen(1000, () => {
console.log("Server Start......");
});

最佳答案
Try this code
var userID =req.query.userid;
var pwd = req.query.pwd
关于javascript - 我无法使用 nodejs 和 mongodb 中的 get 方法从 html 控件中获取数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45369502/
