javascript - FeathersJS 中的非 CRUD 路由

Question

我有一个服务 results，它处理 feathersjs 中 results 服务的所有 CRUD 操作。我将如何创建一个路由 /results/:id/hr_bar_graph，它基本上获取特定 id 处的结果并使用结果数据创建条形图。

我目前的代码是:

module.exports = function (app) {


const Model = createModel(app);
  const paginate = app.get('paginate');

  const options = {
    name: 'results',
    Model,
    paginate
  };



// Initialize our service with any options it requires
  app.use('/results', createService(options));

  app.use('/results/:id/hr_bargraph_image', {
    find(id, params){
      this.app.service('results').get(id)
        .then(function(response){
          console.log(response);
        })
        .cathc(function(error){
          console.log(error);
        })
      return Promise.resolve({
        imageData: ''
      });
    }
  });

  // Get our initialized service so that we can register hooks and filters
  const service = app.service('results');

  service.hooks(hooks);
};

卡在这里有一段时间了。请帮忙。

供引用，来自this issue ，答案是使用params.route和羽毛正常find(params) :

module.exports = function (app) {
  const Model = createModel(app);
  const paginate = app.get('paginate');

  const options = {
    name: 'results',
    Model,
    paginate
  };

  // Initialize our service with any options it requires
  app.use('/results', createService(options));

  app.use('/results/:id/hr_bargraph_image', {
    async find(params){
      const { id } = params.route;
      const results = await app.service('results').get(id);

      return {
        imageData: ''
      };
    }
  });

  // Get our initialized service so that we can register hooks and filters
  const service = app.service('results');

  service.hooks(hooks);
};
