根据文档，您可以传递customHeaders选项...

这意味着您可以执行以下操作：

import i18next from 'i18next';
import HttpApi from 'i18next-http-backend';

i18next.use(HttpApi).init({
  backend: {
    loadPath: 'https://path-to-your-private-cdn',
    customHeaders: {
      authorization: 'some secret or whatever you need to be authorized'
    }
  },
});

或者使用提供此功能的服务，如locize：

import i18next from 'i18next';
import LocizeBackend from 'i18next-locize-backend';

i18next.use(LocizeBackend).init({
  backend: {
    projectId: "[PROJECTID]",
    apiKey: "[APIKEY]",
    version: "[VERSION]",
    private: true
  }
});
