I am learning login registration using mongodb atlas. But I am facing some problems. When i send http post requests for creating new user in emulator its not working and throw some errors. But the same thing works in postman. I can easily create new user in postman. can anyone help me out with this problem?? I am giving my code and error here.
Future signup(email, password) async {
var url = Uri.parse("http://localhost:5050/signup"); // iOS
final http.Response response = await http.post(
url,
headers: {
'Content-Type': 'application/json; charset=UTF-8',
},
body: json.encode({
'email': email,
'password': password,
}),
);
print(response.body);
}
this is my server file:
const express = require('express')
const app = express()
const port = 5050
const mongoose = require('mongoose')
async function connectDB(){
await mongoose.connect('mongodb+srv://imran:123s@cluster0.bupnj.mongodb.net/myFirstDatabase?retryWrites=true&w=majority',
{useUnifiedTopology: true, useNewUrlParser: true}
)
console.log('db connected')
}
connectDB()
app.use(express.json({extended: false}))
// app.get('/', (req, res) => {
// res.send('Hello Backend Server!')
// })
const schema = new mongoose.Schema({ email: 'string', password: 'string' });
const User = mongoose.model('User', schema);
app.post('/signup', async (req, res) => {
const {email, password} = req.body;
// console.log(req.body)
//console.log("Email: "+email);
//console.log("Password: "+password);
let user = new User({
email,
password
})
console.log(user)
await user.save()
res.json({token: "1234567890"})
//return res.send('signup api route!')
})
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`)
})
this the error i got:
