无法在中间件内部发送动作

Question

我创建了jwt中间件

export function jwt({ dispatch, getState }) {
  return (next) => (action) => {
      const authReducer = getState().AuthorizationReducer;

      if(authReducer && authReducer.token.accessToken) {
        const {
          refreshToken,
          time,
        } = getState().AuthorizationReducer.token;

        const details = {
          client_id: authReducer.getToken.clientId,
          client_secret: authReducer.getToken.clientSecret,
          grant_type: 'refresh_token',
          refresh_token: refreshToken
        };

        let now = +Moment(Date.now());

        if (now > time) {
          const queryString = Object.keys(details).map(k => `${encodeURIComponent(k)}=${encodeURIComponent(details[k])}`).join('&');
          return next(getAccessTokenByRefreshToken(queryString));
        }
      }

      return next(action);
  };
}

但我从未进入过getAccessTokenByRefreshToken。看起来像是：

export function getAccessTokenByRefreshToken(queryString) {
  return (dispatch, getState) => {
    dispatch(refreshTokenStart());
    fetch(`${API_URL}oauth/v2/token?${queryString}`, {
      method: 'GET'
    })
      .then(res => {
        if (res.status >= 200 && res.status < 300) {
          return res.json();
        }
      })
      .then(json => {
        console.log(json);
        debugger;
        dispatch(refreshTokenComplete(json));
      })
      .catch((err) => {
        dispatch(refreshTokenError(err.error));
        Actions.launch();
      });
  }
}

我在applyMiddleware函数中使用了redux和aply我的中间件。 问题是我如何发布我的行动？
