egg的使用方法

router.get("/api/main/:id", controller.main.show);

class MainController extends Controller {
    async show() {
        let { id } = this.ctx.params; // 获取路由参数
        let { name } = this.ctx.query; // 获取用户入参
        let options = {
            id: id,
            name: name
        }
        // 调用service方法
        let info = await this.ctx.service.main.getInfo(options);
        // 拼装响应体
        this.ctx.body = {
            code: 0,
            data: info
        };
        this.ctx.status = 200;
    }
}
module.exports = MainController;
