如何使用primus在feathersjs服务方法上添加更多参数

npm install primus feathers primus-feathers --save

const feathers = require('feathers');
const Primus = require('primus');
const primusFeathers = require('primus-feathers');

// 创建FeathersJS应用程序
const app = feathers();

// 配置Primus
const primus = new Primus(app, { transformer: 'websockets' });
app.configure(primusFeathers(primus));

// 启动应用程序
app.listen(3030);

app.service('todos').hooks({
  before: {
    create: [
      (context) => {
        // 在params对象中添加更多参数
        context.params.additionalParam = 'additional value';
        return context;
      }
    ]
  }
});

app.service('todos').hooks({
  after: {
    create: [
      (context) => {
        // 获取额外参数的值
        const additionalParam = context.params.additionalParam;
        console.log(additionalParam); // 输出：'additional value'
        return context;
      }
    ]
  }
});
