javascript - node-cron 仅在 console.log 间隔内不执行脚本

Question

在初始运行时，它会运行 app.js 但是，在间隔期间它会跳过它。我可能在这里做错了什么？

var cron = require('node-cron');

cron.schedule('*/10 * * * * *', function(){
    var shell = require('./app.js');
     commandList = [
        "node app.js"
        ]

        console.log('Bot successfully executed'); 

});

日志:

ec2-user:~/environment $ node forever.js
Bot successfully executed

我猜你的 app.js 会立即执行代码，所以它只是通过 require 它来执行(并且 require 被缓存，所以它只执行一次)。

您应该改为从 app.js 返回函数，并在每次运行时调用它。

// app.js
module.exports = () => { 
    // your original code here
};

// forever.js
var cron = require('node-cron');
var shell = require('./app.js');

cron.schedule('*/10 * * * * *', function(){
    shell();

    console.log('Bot successfully executed');
});

或者您可以在运行前清除require 缓存:

删除 require.cache[require.resolve('./app.js')]
