Я работаю с reduxForm 7.4.2
, я хочу выполнить проверку на стороне сервера с использованием reduxForm
Я нашел много похожих вопросов, но не нашел полезного ответа, поэтому я задаю его снова.
Экспресс-сервер выдает ошибку в правильном формате (status 400 : Bad Request)
, а reduxFrom выдает ошибку ниже:
вот дочерний компонент
import React from 'react'
import { Field, reduxForm ,SubmissionError} from 'redux-form'
const renderField = ({ input, label, type, meta: { touched, error, warning } }) => (
<div className="form-group">
<label>{label}</label>
<input {...input} placeholder={label} type={type} className="form-control" />
{touched && error && <div className="invalid-feedback d-block">{error}</div>}
</div>
)
const Form2Child = (props)=>{
const { handleSubmit, pristine, reset, submitting } = props
return (
<form onSubmit={handleSubmit} className="needs-validation" noValidate>
<Field name="name" type="text" component={renderField} label="Name"/>
<Field name="email" type="email" component={renderField} label="Email"/>
<Field name="password" type="password" component={renderField} label="Password"/>
<div>
<button className="btn btn-primary" type="submit" disabled={submitting}>Submit</button>
<button className="btn btn-default" type="button" disabled={pristine || submitting} onClick={reset}>Clear Values</button>
</div>
</form>
)
}
export default reduxForm({
form: 'form2',
})(Form2Child)
вот родительский компонент
import React, { Component } from 'react'
import Form2Child from './Form2Child'
import axios from 'axios'
import { SubmissionError } from 'redux-form';
class Form2 extends Component {
constructor(){
super();
this.state={
}
}
handleSubmit=values=>{
axios.post('http://localhost:4000/register',values)
.then(res=>{
console.log(res.data);
if(res.status==200){
}
}).catch(err=>{
throw new SubmissionError(err.response.data); <---Here I Am Getting Error
});
}
render() {
return (
<Form2Child onSubmit={this.handleSubmit}/>
)
}
}
export default Form2;
вот код сервера:
const isEmpty = value =>
value === undefined ||
value === null ||
(typeof value === 'object' && Object.keys(value).length === 0) ||
(typeof value === 'string' && value.trim().length === 0);
function validateRegisterInput(data) {
let errors = {};
data.name = !isEmpty(data.name) ? data.name : '';
data.email = !isEmpty(data.email) ? data.email : '';
data.password = !isEmpty(data.password) ? data.password : '';
if (!Validator.isLength(data.name, { min: 2, max: 30 })) {
errors.name = 'Name must be between 2 and 30 characters';
}
if (Validator.isEmpty(data.name)) {
errors.name = 'Name field is required';
}
if (Validator.isEmpty(data.email)) {
errors.email = 'Email field is required';
}
if (!Validator.isEmail(data.email)) {
errors.email = 'Email is invalid';
}
if (Validator.isEmpty(data.password)) {
errors.password = 'Password field is required';
}
if (!Validator.isLength(data.password, { min: 6, max: 30 })) {
errors.password = 'Password must be at least 6 characters';
}
return {
errors,
isValid: isEmpty(errors)
};
}
app.post('/register',function(req,res){
const { errors, isValid } = validateRegisterInput(req.body);
if (!isValid) {
return res.status(400).json(errors);
}
Users.findOne({ email: req.body.email }).then(user => {
if (user) {
errors.email = 'Email already exists';
return res.status(400).json(errors);
} else {
const newUser = new User({
name: req.body.name,
email: req.body.email,
password: req.body.password
});
newUser
.save()
.then(user => res.json(user))
.catch(err => console.log(err));
}
});
})
