Я использую ReactJS для создания простого приложения sendMail. И проблема в том, что я не получаю req.file на моем сервере (ExpressJS).
myForm. js
<form className="content-container mailing-form" encType='multipart/form-data'>
<h1>Let's see if it works</h1>
<div>
<label>Mail: </label>
<input type="text" value={this.state.email} onChange={this.handleChangeToMail} style={{ width: '50%' }} />
</div>
<div>
<label>Subject: </label>
<input type="text" value={this.state.subject} onChange={this.handleChangeSubject} style={{ width: '50%' }} />
</div>
<div>
<textarea
id="test"
name="test-mailing"
onChange={this.handleChangeFeedback}
placeholder="Post some lorem ipsum here"
required
value={this.state.feedback}
style={{ width: '100%', height: '150px' }}
/>
</div>
<div> //Here is my input file
<label>File: </label>
<input
type="file"
onChange={this.handleChangeFile}
name="myFile"
/>
<img src="" id="preview" alt="Image preview..."></img>
</div>
<input type="button" value="Submit" onClick={this.handleSubmit} />
</form>
handleChangeFile
handleChangeFile = e => {
e.preventDefault();
let fReader = new FileReader();
let file = '';
fReader.readAsDataURL(e.target.files[0]);
fReader.onloadend = (event) => {
document.getElementById('preview').src = event.target.result;
file = event.target.result;
this.setState(() => ({ file }));
console.log(this.state.file);
}
}
handleSubmit
handleSubmit = e => {
let formData = new FormData();
formData.append('name', this.state.name);
formData.append('email', this.state.email);
formData.append('feedback', this.state.feedback);
formData.append('subject', this.state.subject);
formData.append('file', this.state.file);
const config = {
headers: {
"Content-Type": "multipart/form-data",
"Accept": "application/json",
"type": "formData"
}
}
const url = "http://localhost:8081/send";
axios
.post(
url,
formData,
config
)
.then(res => console.log(res.data))
.catch(err => console.log('Error: ', err));
}
Сервер. js
const nodemailer = require('nodemailer');
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
var multer = require('multer');
const app = express();
const port = 8081;
app.use(cors());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next(); });
app.get('/', (req, res) => res.send('......!'));
const storage = multer.diskStorage({
destination: './uploads',
filename: function (req, file, cb) {
cb(null, file.fieldname + Date.now());
} })
const uploads = multer({
storage: storage
}).single('myFile');
app.post('/send', uploads, (req, res) => {
if (req.file) {
res.send('Uploaded !');
} else {
res.send('Fail !!');
}
});
app.listen(port, () => console.log(`Example app listening on port ${port}!`));
И я продолжаю получать "Fail !!" сообщение в моей форме.
Я попытался добавить любое решение, которое смогу найти. Я знаю, что там может быть какой-то беспорядок, извините за это: ')!
