javascript - node-cron 仅在间隔时不执行脚本 console.log

问题描述

在初始运行时，它会运行 app.js，但是会在间隔时跳过它。我在这里可能做错了什么？

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

解决方案

我猜你app.js会立即执行代码，所以它只通过要求它来执行（并且要求被缓存，所以它只执行一次）。

您应该从您的app.js而不是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，也许您可​​以require在运行之前清除缓存：

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