Question

index.html

<form action="http://127.0.0.1:5555/sign" method="POST">
      <div class="main">
        <div class="name-container">
          <input type="text" class="input" placeholder="First Name" id="fname" />
          <input type="text" class="input" placeholder="Last Name" id="lname" />
        </div>
        <div class="gender_date">
          <div class="gen">
            <input type="radio" name="gender" value="male" id="male" />
            <label for="male">Male</label>
            <input type="radio" name="gender" value="female" id="female" />
            <label for="female">Female</label>
            <input type="radio" name="gender" value="other" id="other" />
            <label for="other">Other</label>
          </div>
          <div class="date-con">
            <input type="date" class="input" id='date' name="bday" />
          </div>
        </div>
      </div>
    </form>

post 请求正常工作，但名称未显示。后端nodejs文件=> serve.js

const express = require("express");
const fs = require("fs");
const bodyParser = require("body-parser");
const app = express();
var urlencodedParser = bodyParser.urlencoded({ extended: false });

app.get("/sign", (req, res) => {
  res.send("Hello");
});
app.post("/sign", urlencodedParser, (req, res) => {
  res.send(req.body);
  let student = req.body;
  let students = [];
  students.push(student);
  let data = JSON.stringify(students, null, 2);

  fs.writeFile("./file.json", data, err => console.log("success"));
  console.log(students);
});

const PORT = 5555;
app.listen(PORT, err => {
  console.log(`Server Running at port: ${PORT}`);
});

file.json: 输出

[
  {
    "gender": "male",
    "bday": "1999-07-05"
  }
]

来自 "First Name" 和 "Last Name" 字段的值未显示在最终输出中。无论我改变什么，我都无法让它正常工作。提前谢谢你。

<form action="http://127.0.0.1:5555/sign" method="POST">
  <div class="main">
    <div class="name-container">
      <input type="text" class="input" placeholder="First Name" name="fname" />
      <input type="text" class="input" placeholder="Last Name" name="lname" />
    </div>
    <div class="gender_date">
      <div class="gen">

    </div>
  </div>
</form>

很少有字段值没有出现在最终输出中，我使用的是 nodejs
