我不知道如何在客户提交表单后使代码向客户显示，也不知道如何使客户提交多个（多次）我想要这样：
---the form---
input
input
input
submit button
--here show the response--
并且客户端能够发送多次提交，并且响应如上所示。 它还给了我这个错误：
/home/runner/costalica/index.js:87
})
SyntaxError: Unexpected end of input
这是我的代码：
const fetch = require('node-fetch');
const express = require('express');
const app = express();
// Parse request bodies
app.use(express.json());
app.use(express.urlencoded({
extended: true
}));
app.listen(3000);
app.get('/', (request, response) => {
let responseHTML = `
<html>
<body>
<h1>Login Form</h1>
<form method="POST" action="/">
<label for="csrf_token">CSRF Token:</label>
<input type="text" name="csrf_token" id="csrf_token"><br>
<label for="email">Email:</label>
<input type="email" name="email" id="email"><br>
<label for="password">Password:</label>
<input type="password" name="password" id="password"><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
`
response.send(responseHTML)
})
app.post('/', (req, res) => {
const {
csrf_token,
email,
password
} = req.body;
const data = `{

})您的 app.post 到处都缺少括号。
您可以通过删除自包含的对象直到获得正确的结构来找到哪个。例如
app.post('/', (req, res) => {
const {
csrf_token,
email,
password
} = req.body;
fetch('https://scrapeninja.p.rapidapi.com/scrape', { // no need to save

"method": "POST",
"headers": [......]
}), // added
"data": data
}).then(res => { // added the then to the fetch
const json = res.json();
responseHTML += `<pre>${JSON.stringify(json, null, 2)}</pre>`
})
})
