Class AxiosTo<T>

axios通过get、post等方法获取数据后，返回Promise，此类等待并获取Promise的结果。

Example

function isSuccess(x: MasAxiosResponseType) {
  return x.data.code === 200;
}

const to = new AxiosTo(x => {
  if (isSuccess(x)) return x.data.data
  else if (x.data.info) ElMessage.error(x.data.info);
}, isSuccess);
to.showMessage = (message: string) => ElMessage.error(message);

Example

// 如果有其他的返回类型，可以参考以下方法进行扩展，方便对接多个系统
type OtherType<T> = {
  status: number,
  response: T,
  message: string,
};
type OtherAxiosResponse<T = unknown> = AxiosResponse<OtherType<T>>;
type TransOtherFunType<T extends AxiosResponse> = T extends OtherAxiosResponse<infer R> ? R : never
declare class OtherTo<T extends AxiosResponse = OtherAxiosResponse> {
  showMessage: (message: string) => void;
  constructor(getInfoFun: TransFunType<T>, isSuccessFun: IsSuccessType<T>);
  async<R extends T>(promise: Promise<R>, silence?: boolean): Promise<ToResult<R, TransOtherFunType<R>>>;
}

function isSuccess(x: OtherAxiosResponse) {
  return x.data.status === 200;
}

const to = new AxiosTo<OtherAxiosResponse>(x => {
  if (isSuccess(x)) {
    return x.data.response
  }
},isSuccess) as OtherTo;
to.showMessage = (message: string) => ElMessage.error(message);

addEventListener

async

  • async<R>(promise, silence?): Promise<ToResult<R, TransMasFunType<R>>>

  • 等待axios的get、post等方法返回Promise（promise参数），返回ToResult类，调用返回类的ToResult#getInfo方法进而获取解析值， 如果Promise被拒绝，错误不会抛出，可通过返回类的ToResult#err属性获取错误信息，另外根据silence参数，决定错误发生时是否显示错误。

    Type Parameters

    • R extends AxiosResponse<any, any>

    Parameters

    • promise: Promise<R>

      axios返回的的Promise

    • silence: boolean = false

      是否静默，默认值为false，如果为true，当请求失败时不会调用AxiosTo#showMessage方法显示错误信息

    Returns Promise<ToResult<R, TransMasFunType<R>>>

dispatchEvent

hasEventListener

removeEventListener

showMessage

  • showMessage(message): void

  • 当promise被拒绝时，显示错误信息的方法，默认使用console.error打印消息，一般在AxiosTo实例化后，重写此方法。

    Parameters

    • message: string

      错误消息

    Returns void
