+title: Whole Body Validation
+---
+
+Sometimes you need to validate requests whose body is a string, an array, or even a number!
+That's why you can omit the field to validate and check `req.body` directly:
+
+```js
+const bodyParser = require('body-parser');
+const express = require('express');
+const { body } = require('express-validator');
+
+const app = express();
+
+// Will handle text/plain requests
+app.use(bodyParser.text());
+
+app.post('/recover-password', body().isEmail(), (req, res) => {
+  // Assume the validity of the request was already checked
+  User.recoverPassword(req.body).then(() => {
+    res.send('Password recovered!');
+  });
+});
+```
+
+This setup should be able to handle the following request:
+
+```http
+POST /recover-password HTTP/1.1
+Host: localhost:3000
+Content-Type: text/plain
+
+my@email.com
+```
