javascript - 登录成功时token已经存在，如何移动到主页？

Question

如果您成功登录并获得令牌，则页面将重定向到主页，并且在我成功登录并获得令牌后，请查看拍摄的图片。

.

代码在登录文件夹中，感谢您的帮助。

const FormItem = Form.Item;

class Login extends Component {
  constructor(props) {
    super(props);
    this.state = {
      isAuthenticated: this.props.isAuthenticated,
      errorMessage: null,
      isErorloaded: false
    };
  }

  handleRegisterGoogle = request => {
    this.props.loginWithGoogle(this.props.history, request);
  };

  handleSubmit = e => {
    try {
      e.preventDefault();
      this.props.form.validateFields(async (err, values) => {
        if (!err) {
          console.log("Received values of form: ", values);
          await this.props.loginWithForm(values);
        }
      });
    } catch (error) {
      console.log(error);
    }
  };

  render() {

    console.log(this.props.token);

    const { getFieldDecorator } = form;
    const { errorMessage, isErorloaded,isAuthenticated } = this.state;
