我正在使用 Laravel API 和 ReactJS 前端创建一个登录页面。我正在使用Axios在ReactJS中解析用户名(电子邮件)密码。登录的API是http://127.0.0.1:8000/api/login,它在postman form-data中正常工作。但是当我在 react 前端输入 emailpassword 时,回显是 Error: Request failed with status code 401. 此错误抛出通过axios的catch函数。我也在使用querystring npm 也。那么哪个会抛出这个错误呢?

我的 React JS 代码

import React, { Component } from 'react';
import { Button, Card, CardBody, CardGroup, Col, Container, Input, InputGroup, InputGroupAddon, InputGroupText, Row } from 'reactstrap';
import axios from 'axios';
import { Redirect } from 'react-router-dom'
import querystring from 'querystring';


class Login extends Component
{
constructor(props)
{
super(props);
this.onClick = this.onClick.bind(this);

this.state = {
email:"",
password:""
}
}

onClick(event)
{
var self = this;
var payload={
"email":this.state.email,
"password":this.state.password,
}
//axios.post('http://127.0.0.1:8000/api/login', payload) .then((response) => {}
console.log("1. Hello before axios.post");
//axios.post('http://127.0.0.1:8000/api/login', payload)
axios.post('http://127.0.0.1:8000/api/login', querystring.stringify({payload}))

.then((response) =>
{
console.log("2. Inside axios response");
console.log(response);
if(response.data.code == 200)
{
//Set localstorage:
const userDetails = {userName: this.state.email}
localStorage.setItem('userDetails', JSON.stringify(userDetails));

console.log("Login successfull");
return <Redirect to='/Master' />

}

else if(response.data.code == 204)
{
console.log("Username password do not match");
alert(response.data.success)
}

else if(response.data.code == 401)
{
alert(response.data.success)
}

else
{
console.log("Username does not exists");
alert("Username does not exist");
}
})

.catch(function (error)
{
console.log("The error is : " + error);
});
}
render()
{
return (
<div className="app flex-row align-items-center">
<Container>
<Row className="justify-content-center">
<Col md="8">
<CardGroup>
<Card className="p-4">
<CardBody>
<h1>Login</h1>
<p className="text-muted">Sign In to your account</p>
<InputGroup className="mb-3">
<InputGroupAddon addonType="prepend">
<InputGroupText>
<i className="icon-user" />
</InputGroupText>
</InputGroupAddon>
<Input type="text" placeholder="Username" />
</InputGroup>
<InputGroup className="mb-4">
<InputGroupAddon addonType="prepend">
<InputGroupText>
<i className="icon-lock" />
</InputGroupText>
</InputGroupAddon>
<Input type="password" placeholder="Password" />
</InputGroup>
<Row>
<Col xs="6">
<Button color="primary" className="px-4" onClick={this.onClick}>
Login
</Button>
</Col>
<Col xs="6" className="text-right">
<Button color="link" className="px-0">
Forgot password?
</Button>
</Col>
</Row>
</CardBody>
</Card>
<Card
className="text-white bg-primary py-5 d-md-down-none"
style={{ width: 44 + "%" }}
>
<CardBody className="text-center">
<div>
<h2>Sign up</h2>
<p>
Are you a new user to the Restaurant system? Hooray now , you can create an account...
</p>
<Button color="primary" className="mt-3" active>
Register Now!
</Button>
</div>
</CardBody>
</Card>
</CardGroup>
</Col>
</Row>
</Container>
</div>
);
}
}

export default Login;

以下是Laravel API登录代码,需要电子邮件密码

Laravel 登录 API 代码

<?php
namespace App\Http\Controllers\API;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\User;
use Illuminate\Support\Facades\Auth;
use Validator;
class UserController extends Controller
{
public $successStatus = 200;

public function login()
{
if(Auth::attempt(['email' => request('email'), 'password' => request('password')]))
{
$user = Auth::user();
$success['token'] = $user->createToken('MyApp')-> accessToken;
return response()->json(['success' => $success], $this-> successStatus);
}

else
{
return response()->json(['error'=>'Unauthorized'], 401);
}
}
}

更新

Alexhere我更改了 console.log("错误是:"+ error);
as console.log("错误是:"+ error.response);catch 函数中。它回显错误是:[object Object]

最佳答案

这是正确且有效的代码解决方案

axios中设置header的正确方法

axios.post('http://10.0.1.14:8001/api/logout',request_data, {
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer '+token
},
})
.then((response) => {
console.log('response',response.data)

})
.catch((error) => {
alert('error',error.response)
dispatch(userUpdateProfileFail())

})

// console.log('----cheers---------',data)
dispatch(userUpdateProfileSuccess(data))
