我是新的反应/ redux.I有一个Redux操作进行身份验证,之后我需要重定向到一个确认页面回家。我不知道如何重定向
这是我的index.js
import React, { PropTypes } from 'react';
import { connect } from 'react-redux';
import { FormattedMessage } from 'react-intl';
import { createStructuredSelector } from 'reselect';
import {loginAction} from './actions';
export class Login extends React.PureComponent { // eslint-disable-line react/prefer-stateless-function
constructor(props) {
super(props);
this.state = {
username: '',
password: ''
};
// this.handleChange = this.handleChangeUsername.bind(this);
// this.handleSubmit = this.handleChangePassword.bind(this);
}
handleChangeUsername(event) {
console.log(event.target.value);
this.setState({username: event.target.value});
console.log(this.state.username)
}
handleChangePassword(event) {
this.setState({password: event.target.value});
console.log(this.state.password)
}
handleSubmit(event) {
this.props.dispatch(loginAction(this.state));
event.preventDefault();
}
render() {
return (
<div>
<div className="loginColumns animated fadeInDown">
<div className="row">
<div className="col-md-6">
</div>
<div className="col-md-6">

</div>
<div className="form-group">

<button type="submit" className="btn btn-primary block full-width m-b">Login</button>
<a href="#">

);
}
}
Login.propTypes = {
dispatch: PropTypes.func.isRequired,
};
const mapStateToProps = createStructuredSelector({
// Login: makeSelectLogin(),
});
function mapDispatchToProps(dispatch) {
return {
dispatch,
};
}
export default connect(mapStateToProps, mapDispatchToProps)(Login);
action.js
import {
DEFAULT_ACTION,
LOGIN_ACTION
} from './constants';
export function defaultAction() {
return {
type: DEFAULT_ACTION,
};
}
export function loginAction(json) {
return {
type: LOGIN_ACTION,
json
};
}
reducer.js
import { fromJS } from 'immutable';
import {
DEFAULT_ACTION,
LOGIN_ACTION
} from './constants';
const initialState = fromJS({
status: false
});
function loginReducer(state = initialState, action) {
console.log("action", action)
switch (action.type) {
case DEFAULT_ACTION:
return state;
case LOGIN_ACTION:
return _testFunction(state,action.json);
default:
return state;
}
}
function _testFunction(state, json) {
if(json.username == "abcd@gmail.com" && json.password == "1234")
return state.set("status", true)
}
export default loginReducer;
我想在成功登录后重定向/ home。我该如何重定向?
答案 0 :(得分:0)
嗯,你要做的就是这样。将回调传递给您的操作。一旦操作完成它的工作,只需调用该回调,它将以编程方式将您重定向到您需要的URL。提交登录表单后,将带有回调函数的输入值传递给您的操作。
RETURNS TABLE
然后在您的操作中,如果您正在调用后端API,则在解析promise时,请确保调用传递给此类操作的回调函数。
onSubmit(values) {
this.props.loginAction(values, () => {
this.props.history.push('/');
});
}
这就是你所要做的。您可以根据自己的情况和设置对此进行细微更改。我会把它作为练习保留给你。希望这可以帮助。快乐的编码!
