無法將資料從axios傳送到傳回空對象的node伺服器
我的客戶端程式碼：
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<link rel="stylesheet" href="form.css" />
</head>
<body>
<form action="/login" method="post" class="form">
<input type="text" name="txt" class="txt" id="txt" placeholder="name" />
<input type="submit" class="submit" id="submit" />
</form>
<script defer src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
<script>
let submit = document.querySelector(".submit");
const form = document.querySelector(".form");
form.addEventListener("submit", (e) => {
e.preventDefault();
const formData = new FormData(form);
const formObject = {};
formData.forEach((value, key) => {
formObject[key] = value;
});
console.log(axios.defaults)
axios
.post("http://localhost:8080/login", formObject)
.then(function (response) {
console.log(response.data);
})
.catch(function (error) {
console.log(error);
});
});
</script>
</body>
</html>
我的伺服器端程式碼：
const app = express();
const path = require("path");
app.use(express.static('./public',{index:'form.html'}));
app.use(express.urlencoded({extended:true}));
app.post('/login',(req,res)=>{
//const txt = req.body;
console.log('logged data: ',req.body);
res.send('Thanks');
})
app.listen(8080, () => {
console.log('server is running...in port 8080')
});
首先請記住，我是後端新手。當我嘗試console.log 記錄的資料時，它返回一個空對象，我無法理解為什麼我的req.body 返回一個空對象，但是當我嘗試透過給出action:"/login" 和方法來執行相同操作時：表單標籤內的“post”它按預期工作並為我提供我提供的輸入。請有人幫助我，我的頭在燃燒，提前謝謝你。
