当我尝试将表单组件连接到 redux 时，我得到一个无限循环。如果它不令人沮丧会很有趣，因为代码今天早些时候工作，而现在在我恢复 1 次提交后它就没有了。

代码几乎相同，并且 connect()() 有效，并且我可以使用 signUserUp 函数作为道具使用。我删除了 node_modules 和 package-lock 以防万一并再次安装，它是一样的。

注册.js

import { connect } from "react-redux";
import signupActions from "../modules/signup";

function Signup() {
  return <BasicForm />
}

const BasicForm = () => (
  <Formik
    initialValues={{ email: "", password: "", confirmPassword: "" }}
    validationSchema={signupSchema}
    onSubmit={(values, actions) => {
      console.log("form data: ", values);
    }}
    render={({ values, errors, touched, isSubmitting, handleChange, handleBlur, handleSubmit }) => (
      <Container>
        <Form onSubmit={handleSubmit}>
          <Form.Input
            type="text"
            placeholder="Email"
            onChange={handleChange}
            onBlur={handleBlur}
            value={values.email}
            name="email"
          />
          {errors.email && touched.email && <div>{errors.email}</div>}

          <Form.Input
            type="password"
            placeholder="Password"
            onChange={handleChange}
            onBlur={handleBlur}
            value={values.password}
            name="password"
          />
          {errors.password && touched.password && <div>{errors.password}</div>}

          <Form.Input
            type="password"
            placeholder="Confirm Password"
            onChange={handleChange}
            onBlur={handleBlur}
            value={values.confirmPassword}
            name="confirmPassword"
          />
          {errors.confirmPassword && touched.confirmPassword && <div>{errors.confirmPassword}</div>}

          <Button primary type="submit" onSubmit={handleSubmit} disabled={isSubmitting}>
            Submit
          </Button>
        </Form>
      </Container>
    )}
  />
);

export default connect(
  null,
  signupActions
)(Signup);

当我添加连接时，我显然在这里得到了错误......

这是带有 redux 东西 signup.js的单文件模块

import api from '../utils/api';

const SIGN_UP = 'signup/SIGN_UP';

const initialState = {
  isAuthenticated: false,
  jwt: '',
  authError: '',
  formErrors: [],
};

export default (state = initialState, action = {}) => {
  switch (action.type) {
    case SIGN_UP:
      return { ...state, isAuthenticated: true, jwt: action.payload, authError: '', formErrors: [] };
    default:
      return state;
  }
};

export const signup = token => ({
  type: SIGN_UP,
  payload: token,
});

export const signUserUp = credentials => {
  return dispatch => api.post('auth/signup', credentials).then(token => dispatch(signup(token)));
};

在rootReducer.js我像这样导入该 signupReducer

import signupReducer from './modules/signup';

export default combineReducers({
  signup: signupReducer,
});

这是至少在我尝试访问注册页面时查看错误的代码框示例。

问题是您如何应用signupActions（默认导出为 thereducer而不是action creator）到connect.

工作示例（包括以下注释）：https ://codesandbox.io/s/4rook7ryv4

笔记：

containers将您与您分开components：https ://medium.com/@dan_abramov/smart-and-dumb-components-7ca2f9a7c7d0

分开你的actions,reducers和types.

我对您的应用程序进行了重组，使其更易于理解/阅读。我强烈建议您使用下面列出的此流程和结构（或者，如果您希望组件/视图更加模块化，请将与该组件/视图相关的所有内容捆绑到一个文件夹中 - 如果你在一个大团队中工作）。
