如果发布请求成功，则关闭对话框

我正在使用React，Redux，NodeJS和ExpressJS。我还在前端使用material-ui。我创建了一个对话框，用户可以在其中输入信息和注册。用户单击“提交”后，便发出了一个帖子要求。返回的任何错误都将被置于状态中的errors对象中。如果返回任何错误（例如密码不匹配），则会在输入字段下方列出。如果单击了提交按钮，并且没有错误，则对话框保持打开状态。如果没有错误返回，我将如何关闭对话框（state.open应该设置为false）。我该怎么做。这是我的代码：

authActions.js：

export const registerUser = (userData, history) => dispatch => {
  axios
    .post("/api/users/register", userData)
    .then(res => history.push("/signup/done"))
    .catch(err =>
      dispatch({
        type: GET_ERRORS,
        payload: err.response.data
      })
    );
};

signup.js：

class SignUpD extends Component {
  constructor() {
    super();
    this.state = {
      open: false,
      username: "",
      email: "",
      password: "",
      password2: "",
      errors: {}
    };
    this.onChange = this.onChange.bind(this);
    this.onSubmit = this.onSubmit.bind(this);
  }
  componentDidMount() {
    if (this.props.auth.isAutenticated) {
      this.props.history.push("/");
    }
  }
  componentWillReceiveProps(nextProps) {
    if (nextProps.errors) {
      this.setState({ errors: nextProps.errors });
    }
  }

  handleClickOpen = () => {
    this.setState({ open: true });
  };

  handleClose = () => {
    this.setState({ open: false, errors: {} });
  };

  onChange(e) {
    this.setState({ [e.target.name]: e.target.value });
  }

  onSubmit(e) {
    e.preventDefault();

    const newUser = {
      username: this.state.username,
      email: this.state.email,
      password: this.state.password,
      password2: this.state.password2
    };

    this.props.registerUser(newUser, this.props.history);
  }

  render() {
    const { errors } = this.state;

    return (
      <div>
        <ListItem
          button
          style={{ paddingTop: 60, top: 0 }}
          onClick={this.handleClickOpen}
        >
          <ListItemText primary="Sign Up" />
        </ListItem>
