BetterLog 将每条消息的输出复制到 Google App Script 控制台两次

Question

BetterLog Apps Script library 将每条消息打印到Google Apps Script console 两次。 是否可以以某种方式配置它或者它是一个错误？

我使用the library's page推荐的标准配置：

// Add one line to use BetterLog
Logger = BetterLog.useSpreadsheet('your-spreadsheet-key-goes-here'); 

//Now you can log and it will also log to the spreadsheet
Logger.log("That's all you need to do");

带有重复消息的控制台日志示例：

11:23:10 AM Info 2022-06-13 11:23:10:821 +0300 001169 INFO doPost called
11:23:10 AM Info doPost called
11:23:11 AM Info 2022-06-13 11:23:11:289 +0300 001637 INFO doPost - contents: {"message":{"chat":{"id":123},"text":"/test"}}; runFromChatId: 123; text: /test
11:23:11 AM Info doPost - contents: {"message":{"chat":{"id":123},"text":"/test"}}; runFromChatId: 123; text: /test
11:23:11 AM Info 2022-06-13 11:23:11:599 +0300 001947 INFO doPost - not yet validated runFromChatId: 123

大约 1 年前没有这样的问题：消息只打印到控制台一次。从那时起，库或App Script 引擎中发生了一些变化。

现在这似乎是一个错误。 我为这个库创建了相应的问题： BetterLog duplicates output for each message to console two times

---

作为解决方法，您可以执行以下操作：

初始配置：

Logger = BetterLog.useSpreadsheet(SPREADSHEET_ID);
Logger.console = undefined; //Do not print messages to console second time.
//To print to console Logger.nativeLogger_ destination will be used.

用法：

Logger.log("This message will go to console only one time");

Work around for issue "BetterLog duplicates output for each message to console two times"

此解决方法禁用打印到console 目标。记录器仍将通过默认启用nativeLogger_ 目的地的方式打印到控制台。

---

作为第二个解决方法，您可以启用console 目标并禁用BetterLog.nativeLogger_ 目标。消息仍将仅打印一次。但是此解决方案不会将消息的长时间戳打印到控制台。这可能更方便。

现在你可以使用BetterLog而不是作为外部库，而是将它的源代码复制到你的项目中，并自己为这个库添加小修复。以后如果图书馆修好了，就不需要了。

要在本地使用BetterLog，您需要创建新文件，例如名称为“LocalBetterLog”，然后将this file 中的代码粘贴到那里。

应用修复。而不是：

  //default console logging (built in with Google Apps Script's View > Logs...)
  nativeLogger_.log(convertUsingDefaultPatternLayout_(msg, level));

用途：

//Anton Samokat fix: messages are printed to console twicely. 
//Added check for nativeLogger_ is not null and not undefined 
//in order to be able to set nativeLogger_ as null 
//and in such a way to skip printing messages to it.
if(nativeLogger_) { 
  //default console logging (built in with Google Apps Script's View > Logs...)
  nativeLogger_.log(convertUsingDefaultPatternLayout_(msg, level));
}

然后按以下方式启动和配置记录器：

//log config start
//Logger = BetterLog.useSpreadsheet(SPREADSHEET_ID); //Use BetterLog library when it is fixed
const Logger = useSpreadsheet(SPREADSHEET_ID); // For now use local BetterLog logger
//To call function from another file you need just to call
//it by name, no imports, no file names specification.
//Logger.console = undefined; //do not print messages to console
Logger.nativeLogger_ = undefined; //do not print messages to console second time
//Logger.sheet_ = undefined; //do not print messages to sheet (this particular set 
//can be placed in initTestsEnvironment() function for using it in local tests runs 
//in order to skip printing to the sheet for not spamming it during the tests)
//log config end

在所有情况下照常使用：

Logger.log("This message will go to console only one time");
