1、package.json引入对应的包，如下：

"rxai-api-core": "^1.0.0"

2、入口如app.ts全局设置请求工厂实现

import HttpUtils from 'rxai-api-core/dist/HttpUtils';
// 其中RequestImpl是由用户自己编写实现类，详见第3步操作
import RequestImpl from '@/utils/RequestImpl';

HttpUtils.setFactory(() => new RequestImpl());

3、RequestImpl示例如下(icejs的request举例，也可为axios，只要能够实现网络请求)

import { request } from 'ice';
import { RequestParam } from 'rxai-api-core/dist/AbstractApi';

class RequestImpl {
  requestParam: RequestParam;

  init(requestParam: RequestParam) {
    this.requestParam = requestParam;
  }

  start() {
    return request({
      url: this.requestParam.path,
      method: this.requestParam.method,
      data: this.requestParam.data,
      responseType: this.requestParam.responseType,
      headers: {
        'Content-Type': 'application/json',
      },
    });
  }
}

export default RequestImpl;
