Typescript装饰器与lambda的接口。轴向阻力

关于索引中公开的lambda函数,我面临一个typescript问题。d、 ts文件。我试图做的是修饰AxiosInstance,以便在需要时取消挂起的请求。

这是索引。d、 ts文件,来自axios库:

export interface AxiosInstance {

  (config: AxiosRequestConfig): AxiosPromise; // How to override this lambda ?
  (url: string, config?: AxiosRequestConfig): AxiosPromise; // How to override this lambda ?

  // Omit the rest because ther is no problem with it
}

下面是我对AxiosInstance的实现

export default class CancelableAxiosInstance implements AxiosInstance {


    private axiosInstance: AxiosInstance;

    constructor(axiosInstance: AxiosInstance){
        this.axiosInstance = axiosInstance;
    }

    // Another function that I want to expose on CancelableAxiosInstance
    cancelRequests() {
       // Omit implementation
    }

    // How do I override (config: AxiosRequestConfig): AxiosPromise; declared in index.d.ts file ?
 }

以下是IDE中显示的typescript编译器错误:

TS2420: 键入“CancelableAxiosInstance”providesnomatchforthesignature“(配置:AxiosRequestConfig):AxiosPromise”)。

有人能帮我吗?

谢谢
