Decorators

@runapi/requestor: 基于"@runapi/requestor"的装饰器，使用装饰模式定义接口请求函数。

Service Decorator

使用 Service 装饰器将 class 定义为 Service

import { createFetchRequestor, createRequestContext } from "@runapi/requestor";

@Service(requestor)
class UserService {}

export const userService = new UserService();

interface User {
  userId: string;
  username: string;
  gender: string;
}

@Service(requestor)
class UserService {
  @Http("GET", "/user/:userId", { params: { userId: "1" } })
  findUserByUserId(): ResponseContextPromise<User> {}
}

export const userService = new UserService();

Get Decorator

  username: string;
  gender: string;
}

@Service(requestor)
