如何使用 React js 上的历史重定向到另一个页面?
How to redirect to another page using history on React js?
我在前端使用 Reactjs 开发了一个 Singnup 页面,在后端使用 laravel 我希望当我点击注册按钮时,它会被重定向到我的登录页面。
我的注册组件是:
handleSubmit = event => {
event.preventDefault();
const users = {
name:this.state.name,
email:this.state.email,
cin:this.state.cin,
phoneNumber:this.state.phoneNumber,
birthDate:this.birthDate,
password:this.state.password
}
console.log(users)
axios({
method: 'post',
url: 'http://172.16.234.24:8000/api/register',
data: users,
headers: {
'Access-Control-Allow-Origin': '*',
'Content-Type': 'application/json',
'Accept': 'application/json',
}
})
.then(function (response) {
console.log(response);
this.props.history.push('/login');
})
.catch(function (response) {
console.log(response);
});
}
我的路线是:
import React from "react";
import { Route, Switch, } from "react-router-dom";
import Home from "./Home";
import NotFound from "./NotFound";
import Login from "./Login";
import Signup from "./Signup";
export default () =>
<Switch>
<Route path="/" exact component={Home} />
<Route path="/login" exact component={Login} />
<Route path="/signup" exact component={Signup} />
<Route component={NotFound} />
</Switch>;
我的指数是:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from "react-router-dom";
import App from './App';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(
<Router>
<App />
</Router>
, document.getElementById('root'));
serviceWorker.unregister();
我的 App.js 是:
import React, { Component } from 'react';
import { Link } from 'react-router-dom';
import { Nav, Navbar, NavItem } from "react-bootstrap";
import { LinkContainer } from "react-router-bootstrap";
import Routes from "./Routes";
import './App.css';
class App extends Component {
render() {
return (
<div className="App container">
<Navbar fluid collapseOnSelect>
<Navbar.Header>
<Navbar.Brand>
<Link to="/">Home</Link>
</Navbar.Brand>
<Navbar.Toggle />
</Navbar.Header>
<Navbar.Collapse>
<Nav pullRight>
<LinkContainer to="/signup">
<NavItem>Signup</NavItem>
</LinkContainer>
<LinkContainer to="/login">
<NavItem>Login</NavItem>
</LinkContainer>
</Nav>
</Navbar.Collapse>
</Navbar>
<Routes />
</div>
);
}}
export default App;
我的 react-router-dom 版本是 4.3.1,当我 运行 我得到 :
typeerror: cannot read property 'props' of undefined
我该如何解决?
您应该使用 withRouter
高阶组件包装注册组件以获得对 this.props.history
.
的访问权限
刚刚测试过这个 - 它重定向得很好。
(在注册组件内)..
import React, { Component } from "react";
const axios = require('axios');
export default class Signup extends Component {
constructor(props) {
super(props);
this.state = {}
}
handleSubmit = event => {
event.preventDefault();
axios({
method: 'get',
headers: {
"Content-type": "application/json"
},
url: 'https://jsonplaceholder.typicode.com/todos/1'
}).then(response => {
console.log(response);
this.props.history.push('/login');
})
.catch(response => {
console.log(response);
});
}
render() {
return(
<form onSubmit={this.handleSubmit}>
<button
type="submit">
yo
</button>
</form>
)
}
}
尝试使用上面的占位符代码来证明重定向正常工作,然后替换为您的自定义 API + POST
。注意:您可能需要 stringify
POST
负载。
我们不知道您的 App.js 是什么样子,但您的 App.js 还需要包含 <Router />
组件。
尝试在 axios 调用之前隔离 属性:
let { history } = this.props
axios({
method: 'post',
url: 'http://172.16.234.24:8000/api/register',
data: users,
headers: {
'Access-Control-Allow-Origin': '*',
'Content-Type': 'application/json',
'Accept': 'application/json',
}
})
.then(function (response) {
console.log(response);
history.push('/login');
})
.catch(function (response) {
console.log(response);
});
