如何在节点议程中以编程方式定义多个具有相同名称的作业

Question

我正在使用节点议程模块来启动创建的各种 jobs/events 用户。我希望能够创建作业，以便所有作业都由一个函数回调处理，每个事件都根据事件参数进行区分。下面的示例代码

var mongoConnectionString = "mongodb://127.0.0.1/agenda";
var Agenda = require('agenda');
var agenda = new Agenda({db: {address: mongoConnectionString}});

agenda.define('user defined event', function(job,done) {
    var eventParams = job.attrs.data;
    if(eventParams.params === "Test"){
        handleEvent1();
    } else if (eventParams.params === "Test 2") {
        handleEvent2();
    } else {
        handleEvent3();
    }

    done();
});

agenda.on('ready', function() {
  console.log("Ok Lets get start");
  agenda.start();
});

// some how we get our call back executed. Note that params is the unique to each job.
var userEvent = function(params) {
    // Handle a event which repeats every 10 secs
    agenda.every('10 seconds','user defined event',params);
}

使用此代码，mongodb 中的作业被更新而不是插入。有什么办法可以强制插入议程而不是更新议程？如果议程不可能，是否有任何其他模块可以做到这一点？

因为：

Every creates a job of type single, which means that it will only create one job in the database, even if that line is run multiple times.

您需要使用agenda.create, job.repeatEvery and job.save创建多个同名作业：

const job = agenda.create("user defined event", params);
job.repeatEvery("10 seconds");
job.save();
