我有一個(gè)承諾，其中包含另一個(gè)包含解析器的 API 調(diào)用者承諾?，F(xiàn)在，當(dāng)我想使用 .then 作為父承諾時(shí)，我無(wú)法做到這一點(diǎn)，錯(cuò)誤說(shuō)Cannot read property 'then' of undefined，下面是我的示例代碼const getData = () => dispatch => new Promise((resolve) => {  return apiService    .getByParameter(abc)    .then((data) => {      dispatch(update({        name: data.name      }));      resolve();    })    .catch(() => {    });});現(xiàn)在每當(dāng)我嘗試做this.getData().then({<--something-->});它會(huì)拋出錯(cuò)誤Cannot read property 'then' of undefinedgetByParamter 方法來(lái)自一個(gè)類，如下getByParameter(...params) {    const endpoint = `${this.getEndpoint.call(this, ...params)}`;    const timeInitiated = performance.now();    return request(() => axios.get(endpoint, extraHeaders), timeInitiated,      endpoint, ACTIONS.ACTION_GET);  }const request = (rest, timeInitiated, endpoint, action) =>  new Promise((resolve, reject) => {    rest().then(({ data }) => {      const timeResolved = performance.now();      const timeCalculated = millisToMinutesAndSeconds(timeResolved - timeInitiated);      if (endpoint !== LOGS_ENDPOINT && timeCalculated > MAX_EXECUTION_TIME) {        apiLogger.warn(`The endpoint ${endpoint} took ${timeCalculated} seconds for ${action}`);      }      resolve(data);    })      .catch((response) => {        if (!isCancel(response)) {          reject(response);        } else {          apiLogger.debug('Request cancelled');        }      });  });請(qǐng)建議應(yīng)該采取什么解決方案來(lái)實(shí)現(xiàn)我的需要。
