node.js - setInterval＆setTimeout遞增重複命令

Question

我試圖幫助朋友設置一個機器人Picarto.tv，我們有機器人LINK，並沒有默認plugin那裏重複的消息，所以我試圖做一個非常粗（嚴重的是，這太可怕了，我不是開發者）plugin，我嘗試使用SetInterval/SetTimeout，並且在我使用它們時都會將消息放入聊天一次，以設定的時間間隔，然後它會等待，然後在間隔後，它會說消息兩次，然後三次，依此類推。

它看起來像這樣：

Time 1: 
Testing... 

Time 2: 
Testing... 
Testing... 

等。正如我所說，這裏的代碼非常可怕，不要爲此而難過。

var api; 
function handleChatMsg(data) { 
    var recursive = function() { 
     api.Messages.send("Testing Bot Repeat..."); 
     setTimeout(recursive,15000); 
    } 
    recursive(); 
} 



module.exports = { 
    meta_inf: { 
     name: "Repeat Message", 
     version: "1.0.0", 
     description: "Repeats a message every 5 minutes. Message and interval can be changed.", 
     author: "ZX6R" 
    }, 
    load: function (_api) { 
     api = _api; 
    }, 
    start: function() { 
     api.Events.on("userMsg", handleChatMsg); 
    } 
} 

任何人都可以幫我弄清楚爲什麼它會逐漸地說更多的消息嗎？

編輯：發出定額，新的代碼是

var api; 
// Function to call for the repeating 
function handleChatMsg() { 
// This sets the interval of 5 minutes, and calls the variable. Edit the numbers after the comma to change the interval. You MUST put it into milliseconds. 
setInterval(function(){xyz()}, 15000); 
// This sets the variable, edit the text in "api.Messages.send" to change what the bot repeats. 
var xyz = function() 
{ 
    api.Messages.send("Testing...") 
} 
} 


// defines some information about the plugin, and sets up stuff we need. 
module.exports = { 
    meta_inf: { 
     name: "Repeat Message", 
     version: "1.1.1", 
     description: "Repeats a message every 5 minutes. Message and interval can be changed.", 
     author: "ZX6R" 
    }, 
load: function (_api) { 
     api = _api; 
    }, 
    start: function() { 
     handleChatMsg(); 
    } 
}

Answer 1

讓我們不要使事情變得複雜，並使其更簡單。

setInterval(function(){xyz()}, 300000); 

var xyz = function() 
{ 
    //Do what you want your function to do. 
} 

這裏函數xyz會每300,000毫秒調用一次，這意味着5分鐘。

看看Node Cron順便說一句，如果你打算經常使用它的應用程序。

Answer 2

也許類似以下內容：

// define and export module 
var plugin = {}; 
module.exports = plugin; 

// plugin metadata 
plugin.meta_inf = { 
     name: "Repeat Message", 
     version: "1.0.0", 
     description: "Repeats a message every 5 minutes. Message and interval can be changed.", 
     author: "ZX6R" 
    }; 

/** 
* To be called on plugin load. 
* @param {Object} api - api instance. 
*/ 
plugin.load = function(api){ 
    plugin._api = api; 
}; 

/** 
* Called on plugin start. 
*/ 
plugin.start = function(){ 

    if(!plugin._api){ 
     // api instance should have been available 
     throw new Error("api not defined, is plugin load()'ed ?"); 
    } 

    // each user message event (re)configures the repeating timer 
    plugin._api.Events.on("userMsg",function(){ 
     plugin._configure(true, "Testing echo bot...",15000); 
    }); 
}; 

/** 
* Configure the repeating timer 
* @param {Boolean} enabled - true to enable timer, false to disable 
* @param {String} message - message to repeat, required if enabled 
* @param {Number} interval - milliseconds between repeats, required if enabled 
*/ 
plugin._configure = function(enabled, message, interval){ 

    if(plugin._timer){ 
     // always clear any old timer 
     clearInterval(plugin._timer); 
    } 

    if(enabled){ 
     if(!message || !interval){ 
     // message and interval are required 
     throw new Error("message and interval are required."); 
     } 

     // set a repeating timer 
     plugin._timer = setInterval(function(){ 
     plugin._api.Messages.send(message); 
     },interval); 
    } 

}; 

注：

1. 用戶信息事件採用計時器上一個新的設置。您可以擁有機器人重複用戶消息或自定義內容。
2. 或者，您只能配置一次計時器。
