未捕获的TypeError:this.props.signinUser不是函数(...)

Question

SRC /动作/ index.js

import axios from 'axios';
const ROOT_URL = "http://localhost:3090";

export function signinUser({ email, password }){
    return function(dispatch){
        axios.post(`${ROOT_URL}/signin`, { email, password });
        console.log("hey");
    }
} 

SRC /组件/ AUTH

import React, { Component } from 'react';
import { reduxForm } from 'redux-form';
import * as actions from '../../actions';
class Signin extends Component {


    handleFormSubmit({ email, password }){
            this.props.signinUser({ email, password });

        }

    render() {
        // code
        console.log(actions)
        const { handleSubmit, fields: { email,password } } = this.props;
        return (
        <form onSubmit={handleSubmit(this.handleFormSubmit.bind(this))}>
            <fieldset className="form-group">
                <label>Email:</label>
                <input {...email} className="form-control" />
            </fieldset>
            <fieldset className="form-group">
                <label>Password:</label>
                <input {...password} className="form-control" />
            </fieldset>
            <button action="submit" className="btn btn-primary">Sign In</button>

        </form>
    );
    }

    // methods
}

export default reduxForm({
    form: 'signin',
    fields: ['email',  'password']
}, null, actions)(Signin);

我正在使用Redux表格进行签名.这是我点击"登录"按钮时出现的错误.也许signinUser()函数没有正确定义.

bundle.js:29019 Uncaught TypeError:this.props.signinUser不是函数(...)

Answer 1

如果有人遇到它(我现在对Udemy做同样的啧啧),这是redux-form 5.x和6之间的一个重大变化.基本上,你只需要通过reduxForm运行它并连接,如图所示此评论https://github.com/erikras/redux-form/issues/1050#issuecomment-221721848.

最终结果如下:

Sigin = reduxForm({ form: 'sigin', fields: [ 'email', 'password' ] })(Sigin);
export default connect(null, actions)(Sigin);

您可以查看我的github repo,了解您在此处使用vx.5.0的redux-form成功实现的相同问题.这是基于Stephen Grider的Advanced React和Redux Udemy课程.如果你喜欢它,那就明星吧.

关于您当前的问题:

Redux Form v6实现了一些不同的逻辑.而不是fieldset你使用Field和导入它与reduxForm一起:

import { reduxForm, Field } from 'redux-form';

由于新版本没有内置的连接方法,您需要:

import { connect } from 'react-redux';

在您的特定实例中,您的其余代码应重构如下:

const renderInput = field => {
    const { input, type } = field;
    return (
        <div>
            <input {...input} type={type} className="form-control" />
        </div>
    );
}

class Signin extends Component {
    handleFormSubmit({ email, password }) {    
        this.props.signinUser({ email, password });
    }

    render(){
        const { handleSubmit } = this.props;

        return (
            <form onSubmit={handleSubmit(this.handleFormSubmit.bind(this))}>

                <div className="form-group">
                    <label>Email:</label>
                    <Field name="email" 
                        type="email" component={renderInput} />
                </div>
                <div className="form-group">
                    <label>Password:</label>
                    <Field name="password" 
                        type="password" component={renderInput} />
                </div>
                <button action="submit" className="btn btn-primary">Sign in</button>
            </form>
        );
    }
}

function mapStateToProps(state) {
    return { form: state.form };
}

Signin = connect(mapStateToProps, actions)(Signin);
Signin = reduxForm({
 form: 'signin'
})(Signin);
export default Signin;

在Redux表单迁移指南中,您将看到允许您保持更新的正确新语法.
