NodeJS - expressJS - req.body 只得到一个变量
[英]NodeJS - expressJS - req.body only get one variable
问题描述
我正在尝试创建登录和注册页面，登录页面可以正确获取所有变量，而注册仅出于某种原因传输密码。
应用程序.JS：
var express = require("express");
var app = express();
var bodyParser = require("body-parser");
// configure the app to use bodyParser()
app.use(bodyParser.urlencoded({extended: true,}));
app.use(bodyParser.json());
const port = process.env.PORT || 5555;
const usersSignup = [];
const { Client } = require("pg");
//Create static files
app.use(express.static(__dirname));
app.post("/sign-in", function (req, res) {
let email = req.body.email;
let pass = req.body.psw;
index = usersSignup.findIndex((x) => x.user === email && x.pass === pass);
if (index != -1) {
if (email == "Admin@g.com" && pass == "Admin") {
res.redirect("/contact");
}
res.send(
`Welcome!` + JSON.stringify(email) + "Password:" + JSON.stringify(pass)
);
console.log("Hello");
} else {
res.send("User not found");
console.log("User not found");
}
});
app.post("/sign-up", function (req, res) {
console.log(req.body);
var Fname = req.body.firstName;
var Lname = req.body.lastName;
var pass = req.body.Password;
var email = req.body.email;
var pCode = req.body.promoCode;
con.query("select * from users where email=$1", [email], (err, res) => {
var result = JSON.stringify(res.rows[1]);
if (result != null) {
console.log("User exists");
} else {
con.query(
"INSERT INTO users (Name,FamilyName,Email,PromoCode,Password) values($1,$2,$3,$4,$5)",
[Fname, Lname, email, pass, pCode]
);
}
});
注册表单- req.body 只获取密码（psw），没有别的......我试图禁用模式但同样的问题。 相关的 function 用于检查两个密码是否相同并检查密码限制（6 位数字、大写等...）

<div class="form-group row">

您没有为注册设置名称属性！
<form method="POST" action="sign-up">

<div class="col-sm-6">
<input type="text" class="form-control form-control-user" id="lastName" name="lastName"
placeholder="Last Name">
</div>
</div>
<div class="form-group">
<input type="email" class="form-control form-control-user" id="email" name="email"
placeholder="Email Address">
</div>
<div class="form-group row">
<div class="col-sm-6 mb-3 mb-sm-0">

您忘记了name属性
<input type="text" class="form-control form-control-user" id="firstName"
placeholder="First Name">
应该
<input type="text" class="form-control form-control-user" id="firstName" name="firstName"
placeholder="First Name">
HTML forms 使用name发送数据，而不是id
对所有输入执行此操作，您也在 HTML 上写了name="psw"但在服务器部分执行req.body.Password ，您也需要更正此问题。
固定 HTML：
<form method="POST" action="sign-up">
<div class="form-group row">
<div class="col-sm-6 mb-3 mb-sm-0">
<input type="text" class="form-control form-control-user" id="firstName" name="firstName"
placeholder="First Name">
</div>
<div class="col-sm-6">
<input type="text" class="form-control form-control-user" id="lastName" name="lastName"
placeholder="Last Name">
</div>
</div>
<div class="form-group">
<input type="email" class="form-control form-control-user" id="email" name="email"
placeholder="Email Address">
</div>
<div class="form-group row">
<div class="col-sm-6 mb-3 mb-sm-0">
<input type="password" onclick="validFunc()" class="form-control" id="Password" name="Password"
placeholder="Password" required>
</div>
<div class="col-sm-6">
<input type="password" class="form-control form-control-user" id="RePassword"
placeholder="Repeat Password">
</div>
</div>
<div class="form-group">
<input type="test" class="form-control form-control-user" id="promoCode" name="promoCode"
placeholder="Promo Code">
</div><br>
<button type="button" onclick="displayForm()" class="btn btn-primary" data-toggle="modal"
data-target="#ModalMessage">Sign Up</button>
<div class="signUp"><br>

您可以发布您用于密码onClick的validFunc()的内容，以及表单提交时使用的displayForm()的内容吗？ 我怀疑缺少的字段以某种方式在您的内容检查代码中undefined 。
