制作两个或多个对象并在节点js中旋转或随机使用它们

Question

我有 config.js 个文件包含：

exports.smtp = {
    host: "smtp.mailtrap.io",
    port: "2525",
    auth: true,
    user: "3295b90cbc8837",
    pass: "x"
};

在另一个文件中，我像这样获取 smtp 元素：

var smtp = {
    host: config.smtp.host,
    port: config.smtp.port,
    secure: false
};

我需要创建多个 smtp 对象并随机选择使用哪个 .示例：

exports.smtp = {
    host: "smtp.mailtrap.io",
    port: "2525",
    auth: true,
    user: "3295b90cbc8837",
    pass: "x"
};

exports.smtp = {
    host: "smtp.mailtrap.io",
    port: "2525",
    auth: true,
    user: "3295b90cbc8837",
    pass: "x"
};

两个对象之间会轮流使用 .我该怎么做才能做到这一点？

旋转我不确定，但你可以像这样随机化。您可以像这样创建您的 smtp 详细信息

const data = {
'1' : {
    //here you have your smtp details
    id: 1
},
'2' : {
    //here you have your smtp details
    id: 2
},
'3' : {
    //here you have your smtp details
    id: 3
},
'4' : {
    //here you have your smtp details
    id: 4
}
}

function getSmtpDetails(){
  //I am using 4 as i have 4 object. you should use as many as u have
   var id = Math.floor(Math.random() * 4)+1
   return data[id];
 }

//那么这应该给你不同的对象

 console.log(getSmtpDetails())

交替

const data = [ {
    //here you have your smtp details
    id: 1
 }, {
    //here you have your smtp details
    id: 2
 }, {
    //here you have your smtp details
    id: 3
 }, {
    //here you have your smtp details
    id: 4
 }
]
function getSmtpDetails(){
   return data[Math.floor(Math.random() * data.length)];
}
console.log(getSmtpDetails())
