定义service

app\service\role.js

  async delItem() {
    const { ctx } = this;
    let results;
    await ctx.model.Role.deleteOne({ name: 'test-S3' }).then(res => {
      console.log('results-del-success', res);
      results = res?.deletedCount > 0;
    }).catch(err => {
      console.log('results-del-fail', err);
      results = false;
    });
    return results;
  }

定义controller

  async del() {
    const { ctx } = this;
    const res = await ctx.service.role.delItem();
    console.log('controller', res);
    ctx.body = {
      code: 0,
    };
  }

      results = res?.deletedCount > 0;
