Javascript 正在尝试从mapDispatchToProps发送的操作创建者返回承诺

我有一个这样的动作创造者

export const register = user => {
  return dispatch => {
    dispatch(requestRegistation());
    return new Promise((resolve, reject) => {
      Axios.post(make_url('/users'), { user: user }).then(response => {
        if (response.data.errors) {
          reject(response.data.errors);
        }
        if (response.data.user) {
          resolve(response.data.user);
        }
      });
    });
  };
};

handleSubmit: (values, props) => {
  props.props.register(values).then(
    response => {
      console.debug('response', response);
    },
    errors => {
      console.debug('errors', error);
    },
  );
}
const mapDispatchToProps = (dispatch, ownProps) => {
  return {
    register: user => {
      dispatch(register(user));
    },
  };
};

我有一张这样的表格

export const register = user => {
  return dispatch => {
    dispatch(requestRegistation());
    return new Promise((resolve, reject) => {
      Axios.post(make_url('/users'), { user: user }).then(response => {
        if (response.data.errors) {
          reject(response.data.errors);
        }
        if (response.data.user) {
          resolve(response.data.user);
        }
      });
    });
  };
};

handleSubmit: (values, props) => {
  props.props.register(values).then(
    response => {
      console.debug('response', response);
    },
    errors => {
      console.debug('errors', error);
    },
  );
}
const mapDispatchToProps = (dispatch, ownProps) => {
  return {
    register: user => {
      dispatch(register(user));
    },
  };
};

在我看来，我似乎没有兑现承诺

signup.js:186 Uncaught (in promise) TypeError: Cannot read property 'then' of undefined

signup.js:186相对于

props.props.register（值）。然后（

我感觉自己很接近，但我不确定我在这里缺少了什么？

您没有从

mapDispatchToProps

中的

register

函数返回承诺。您可以删除函数体以使返回隐式，或者添加

return

语句

const mapDispatchToProps = (dispatch, ownProps) => {
  return {
    register: user => dispatch(register(user)),
  };
};

尝试从props函数中删除函数体

{}

。

register:user=>dispatch（register（user））

以使其隐式返回承诺。您现在不会从该函数返回任何内容。请看，太棒了！谢谢！就是这样。@Tholle
