[英]Dispatching an in-progress action in Redux
我有一个注册表单,该表单将数据异步发布到API,然后根据响应执行一些操作。 我将在调用函数后立即分派“ signup_in_progress”操作,有效载荷为“ true”,并基于此更新我的状态,然后在解决诺言时,以有效载荷“ false”分派此操作。
通过在reducer中放入console.log()语句,我可以看到调度是按预期进行的。
我想发生的事情是当signup_in_progress状态为“ true”时,出现微调框而不是注册表单。 但这没有发生。 知道我缺少什么吗?
我的动作:
export function signUpUser(props) {
return function(dispatch) {
dispatch({ type: SIGNUP_IN_PROGRESS, payload: true });
axios
.post(`${ROOT_URL}/signup`, props)
.then(() => {
dispatch({ type: SIGNUP_IN_PROGRESS, payload: false });
dispatch({ type: SIGNUP_SUCCESS });
browserHistory.push(`/signup/verify-email?email=${props.email}`);
})
.catch(response => {
dispatch({ type: SIGNUP_IN_PROGRESS, payload: false });
dispatch(authError(SIGNUP_FAILURE, response.response.data.error));
});
};
}
我的减速器的相关部分:
import {
...
SIGNUP_IN_PROGRESS,
SIGNUP_SUCCESS,
SIGNUP_FAILURE...
} from '../actions/types';
export default function(state = {}, action) {
switch (action.type) {
...
case SIGNUP_IN_PROGRESS:
return { ...state, signing_up: action.payload };
...
我连接的组件:
import React, { Component, PropTypes } from 'react';
import { connect } from 'react-redux';
import { Field, reduxForm } from 'redux-form';
import * as actions from '../../actions';
import SignupFirstPage from './signupComponents/signupFirstPage';
import SignupSecondPage from './signupComponents/signupSecondPage';
import SignupThirdPage from './signupComponents/SignupThirdPage';
import Spinner from 'react-spinkit';
class SignUp extends Component {
constructor(props) {
super(props);
this.nextPage = this.nextPage.bind(this);
this.previousPage = this.previousPage.bind(this);
this.state = {
page: 1
};
this.handleFormSubmit = this.handleFormSubmit.bind(this);
}
nextPage() {
this.setState({ page: this.state.page + 1 });
}
previousPage() {
this.setState({ page: this.state.page - 1 });
}
handleFormSubmit(props) {
this.props.signUpUser(props);
}
render() {
const { handleSubmit } = this.props;
const { page } = this.state;
if (this.props.signingUp) {
return (
<div className="dashboard loading">
<Spinner name="chasing-dots" />
</div>
);
}
return (
<div>
{page === 1 && <SignupFirstPage onSubmit={this.nextPage} />}
{page === 2 && (
<SignupSecondPage
previousPage={this.previousPage}
onSubmit={this.nextPage}
/>
)}
{page === 3 && (
<SignupThirdPage
previousPage={this.previousPage}
onSubmit={values => this.props.signUpUser(values)}
/>
)}
<div>
{this.props.errorMessage &&
this.props.errorMessage.signup && (
<div className="error-container">
Oops! {this.props.errorMessage.signup}
</div>
)}
</div>
</div>
);
}
}
function mapStateToProps(state) {
return {
singingUp: state.auth.signing_up,
errorMessage: state.auth.error
};
}
SignUp = reduxForm({ form: 'wizard' })(SignUp);
export default connect(mapStateToProps, actions)(SignUp);
您的代码中只有一个错字:
function mapStateToProps(state) {
return {
singingUp: state.auth.signing_up, // TYPO!!
errorMessage: state.auth.error
};
}
应该更改为
function mapStateToProps(state) {
return {
signingUp: state.auth.signing_up,
errorMessage: state.auth.error
};
}
我建议使用redux-pack ,它允许您在化简器中处理请求的三个阶段:启动,成功和错误。 然后,您可以使用启动处理程序将布尔值设置为true,并在成功时将其设置为false。
