问IE 11在API调用中未传递Authorization标头

EN

   const axiosInstance = axios.create({
  baseURL: `https://abc.api.nonprod.org/`
});

export const createTokenHeaders = (idToken, accessToken) => ({
  authorization: `Bearer ${idToken}`,
  accessToken: `Bearer ${accessToken}`
});
// Add a request interceptor
export const reqInterceptor = config =>
  // get the bearer token and add it in the header
  Auth.currentSession()
    .then(data => {
      const idToken = data.getIdToken().getJwtToken();
      const accessToken = data.getAccessToken().getJwtToken();
      // eslint-disable-next-line no-param-reassign
      config.headers = Object.assign({}, config.headers, createTokenHeaders(idToken, accessToken));
      return config;
    })
    .catch(err => {
      console.log(err);
      throw new Error('Error getting bearer token');
    });

axiosInstance.interceptors.request.use(reqInterceptor);

export const performGet = (uri, queryParams = {}, headers) => {
  const requestParams = {
    params: queryParams,
    headers

  return axiosInstance.get(uri, requestParams);
};
