Question

我正在尝试使用Seneca为笔记创建微服务。我需要通过Postman通过ID获取所有笔记和笔记。到目前为止，由于不需要传递参数，因此我设法获取了所有注释。但是我只能得到一个带有预定义ID的音符。如何在Seneca.js中从Postman接收查询参数？我是塞内卡（Seneca）的新手，所以其他技巧也将不胜感激。提前致谢。到目前为止，这是我的代码：

const seneca = require('seneca')()
              .use('seneca-entity')
const app = require('express')();
const web = require('seneca-web');
const cors = require('cors');
const fs = require('fs');

//get all notes from a json file
const rawnotes= fs.readFileSync('notes.json');
const notes = JSON.parse(rawnotes);

//Store notes in an array
let arr = [];
for (var key in notes.notes) {
  if (notes.notes.hasOwnProperty(key)) {
    arr.push(notes.notes[key]);
  }
}

console.log("ARR[1]:");
console.log(arr[1]);

const Routes = [{
  prefix: '/api',
  pin: 'role:notes,cmd:*,id:2',
  map: {notes: {GET: true},
      // http://localhost:8082/api/noteById/id?=2 gets note with id 2, regardless of what id is defined as in Postman
        noteById: {GET: true, suffix: '/:id'}} 
},{
  prefix: '/api',
  pin: 'area:categories,action:*',
  map: {categories: {GET: true}}
}];
app.use(cors());
var config = {
  routes: Routes,
  adapter: require('seneca-web-adapter-express'),
  context: app,
  options: {parseBody: true}
}
seneca.client()
.use(web, config)
.ready(() => {
  var server = seneca.export('web/context')()
  server.listen('8082', () => {
    console.log('server started on: 8082')
  })
});
seneca.add({role: 'notes', cmd: 'notes'}, function (args, done) {
  try {
    done(null, {response: notes})
  } catch (err) {
    done(err, null)
  }
});
seneca.add({role: 'notes', cmd: 'noteById'}, function (msg, reply) {
  console.log('MSG.ID IS: ' + msg.id); //2, no matter what is specified in Postman
  reply(null, { response: arr[msg.id - 1] })
});
seneca.act({role: 'notes', cmd: 'noteById', id: 2}, function(err, result) {
    console.log("RESULT IS: ");
    console.log(result);
})

seneca.add({area: 'categories', action: 'categories'}, function (args, done) {
  try {
    done(null, {response: categories})
  } catch (err) {
    done(err, null)
  }
});

notes.json：

    "notes": { 
        "note1": {
            "id": "1",
            "name": "a note",
            "description": "an example note", 
            "created date": "20.11.2019",
            "modified date": "21.11.2019",
            "class": "moderate"
        },
        "note2": {
            "id": "2",
            "name": "another note",
            "description": "another example note", 
            "created date": "22.11.2019",
            "modified date": "23.11.2019",
            "class": "critical"
        }
    }    
}
