Express req.body在表单提交中为空 [英] Express req.body is empty in form submission

问题描述

我有以下表格，提交后结果为空req.body这是我的HTML:

I have the following form and submitting it results in an empty req.body This is my HTML:

<form action="/contact" name="contactUs" id="contactUs" method="POST">
   <label for="email">Email Message</label>
   <input type="text" name="email" id="email">
  <input type="submit" value='Save'>
</form>

这是我的server.js的(部分):

 app.use(bodyParser.json());
 app.use("/", expressStaticGzip("dist"));

app.post("/contact", (req, res) => {
  console.log('anyone there?')
  res.json(req.body);
});

console.log正常工作.我得到了req.body的空对象.

The console.log works fine. I get an empty object for req.body though.

推荐答案

您正在以HTML POST的形式提交，这意味着您正在使用Content-Type: application/x-www-form-urlencoded.

You're submitting as HTML POST that means you are using Content-Type: application/x-www-form-urlencoded.

这意味着您需要添加app.use(express.urlencoded({ extended: false })) ，这样express可以解析该请求并将其放入req.body

This means that you need to add app.use(express.urlencoded({ extended: false })) , This way express can parse that request and put it to req.body
