Logging 如何在自定义ColdFusion日志文件中获得新行？

我已经构建了一个ColdFusion自定义标记来记录错误消息和其他字符串，只要我在开发过程中需要它

我的自定义标记是用cfscript编写的。我试着记录我能得到的一切。因此，每当我在“logMessage”中添加一个新字符串时，我都希望记录一个新行

我试图包含一个变量

crlf = chr(10) & chr(13);

但这不起作用。我认为writeLog（和相应的cflog）不应该添加新行吗

这就是我尝试使用变通方法（每当管道出现时使用writeLog（））的原因，但这会产生大量开销，因为每次运行writeLog（）时都会有大量元数据

这是我的剧本。第一行评估给定的属性（如“logType”和cfcatch对象），并将值（如果已定义）附加到“logMessage”中

请向下查看包含for循环的最后几行

<cfscript>
logMessageDelimiter="*******************************************************";
logMessage = "";
fileName = application.standard_log_path & application.server_name & "_standardLog";
logType = "information";
crlf = chr(10) & chr(13);

if(isDefined("attributes")){    //any attribute is given

    if(isDefined("attributes.text")){ //a custom text is given
        logMessage &= "LogMessage: " & attributes.text & " |" ;
    }

    if(isDefined("attributes.file")){   //output filename
        fileName = application.standard_log_path & application.server_name & "_" & attributes.file;
    }

    if(isDefined("attributes.logType")){ //a loglevel type
        switch(attributes.logType){
            case "i":
                logType = "information";
                break;
            case "w":
                logType = "warning";
                break;
            case "e":
                logType = "error";
                break;
            case "f":
                logType = "fatal";
                break;
            default:
                logType = "information";
        }
    }

    if(isDefined("attributes.catch")){ //catch object is defined
        logMessage &= "CFCATCH defined: " & " | ";

        if(isDefined("attributes.catch.detail"))
                logMessage &= "detail: "  & attributes.catch.detail & " | ";
        if(isDefined("attributes.catch.ErrorCode"))
                logMessage &= "ErrorCode: "  & attributes.catch.ErrorCode & " | ";
        if(isDefined("attributes.catch.ErrNumber"))
                logMessage &= "ErrNumber: "  & attributes.catch.ErrNumber & " | ";
        if(isDefined("attributes.catch.ExtendedInfo"))
                logMessage &= "QueryError: "  & attributes.catch.ExtendedInfo & " | ";
        if(isDefined("attributes.catch.message"))
                logMessage &= "message: "  & attributes.catch.message & " | ";
        if(isDefined("attributes.catch.RootCause"))
                logMessage &= "RootCause: "  & attributes.catch.RootCause & " | ";
        if(isDefined("attributes.catch.TagContext"))
        {
            for(i=1; i LTE ArrayLen(attributes.catch.TagContext); i=i+1)
            {
                logMessage &= "TagContext["& i &"] Column: " & attributes.catch.TagContext[i]["Column"] & " | ";

                logMessage &= "TagContext["& i &"] Line: " & attributes.catch.TagContext[i]["Line"] & " | ";
                logMessage &= "TagContext["& i &"] RawTrace: " & attributes.catch.TagContext[i]["Raw_Trace"] & " | ";
                logMessage &= "TagContext["& i &"] Template: " & attributes.catch.TagContext[i]["Template"] & " | ";
                logMessage &= "TagContext["& i &"] Type: " & attributes.catch.TagContext[i]["Type"] & " | ";
            }
        }

        if(isDefined("attributes.catch.Type"))

                logMessage &= "SQLState: "  & attributes.catch.SQLState & " | ";
        if(isDefined("attributes.catch.SQL"))
                logMessage &= "SQL: "  & attributes.catch.SQL & " | ";
        if(isDefined("attributes.catch.QueryError"))
                logMessage &= "QueryError: "  & attributes.catch.QueryError & " | ";        
        if(isDefined("attributes.catch.Where"))
                logMessage &= "Where: "  & attributes.catch.Where & " | ";
        if(isDefined("attributes.catch.ErrNumber"))
                logMessage &= "ErrNumber: "  & attributes.catch.ErrNumber & " | ";          
        if(isDefined("attributes.catch.MissingFileName"))
                logMessage &= "MissingFileName: "  & attributes.catch.MissingFileName & " | ";

        if(isDefined("attributes.catch.LockName"))
                logMessage &= "LockName: "  & attributes.catch.LockName & " | ";
        if(isDefined("attributes.catch.LockOperation"))
                logMessage &= "LockOperation: "  & attributes.catch.LockOperation & " | ";
        if(isDefined("attributes.catch.ExtendedInfo"))
                logMessage &= "ExtendedInfo: "  & attributes.catch.ExtendedInfo & " | ";
    }
}
splittedText = listToArray(logMessage,'|');
for(i=1; i LTE ArrayLen(splittedText); i=i+1)
{
    //I really need a better solution than this loop... 
    writeLog(splittedText[i],logType,true,fileName);
}
writeLog(logMessageDelimiter,logType,true,fileName);

那你会怎么做？有没有一种方法可以在不反复执行writeLog（）的情况下获取新行

我希望看到这样的结果：

<cftry>
  ...some buggy code
<cfcatch>
  <customTagName text="Hey, you've got an error!" file="myLogFile" type="e" catch="#cfcatch#">
</cfcatch>
</cftry>

"Information","ajp-bio-8013-exec-37118","02/11/13","14:26:09","SYS_MYSYS","LogMessage: Hey, you've got an error!"
    "CFCATCH defined:  "
    " detail:  "
    " ErrorCode:  "
    " ErrNumber: 0 "
    " QueryError:  "
    " message: Errormessage from CF telling me my errors "
    " TagContext[1] Column: 0 "
    " TagContext[1] ID: CF_CFPAGE "
    " TagContext[1] Line: 183 "
    " TagContext[1] RawTrace:       at cffileecfm1278323672._factor2(/the/path/to/my/file.cfm:183) "
    " TagContext[1] Template: /the/path/to/my/file.cfm"
    " TagContext[1] Type: CFML "
    ...

我可以使用方法写入文件，但我认为这也不是最好的方法，不是吗？另外：我不能从我的应用程序中写入coldfusion的标准日志文件夹（例如/path/to/coldfusion/instancename/logs/myLogFolder）

---

有没有办法让我的日志文件具有某种结构？你有什么想法吗？

没有。我刚刚验证了CF用空格替换CRLF字符。就这样。我猜它是这样做的，这样日志解析器就可以告诉我CRLF表示日志项的结束，而不必担心它是日志消息的一部分。在我看来，CF有点懒惰。有趣的是，Railo并没有这样做

---

你能做的最好的事情就是粘贴一些其他的ASCII字符（我刚刚测试了chr（30）-记录分隔符），然后编写一个日志查看器，用CRLF替换掉它。这不是一个很好的建议，但如果它对您很重要，它是一个选项。

FYI，CRLF是

Chr（13）和Chr（10）不是相反，为什么您认为cflog和writelog不会添加新行？我很确定cflog和writelog会转义或忽略新行。这通常是您想要的，因为每个条目都有一行。由于您已经通过单个标记进行了日志记录，您可能希望使用文件API以您想要的格式直接写入文件。如果您确实希望对输出进行这种级别的控制，可以使用cffile action=“write”创建您自己的日志CFC或者fileWriteLine？我认为可以使用文件API，但我只是想找到一种使用cflog writeLog（）的方法。不过还是要谢谢你。我为此提出了一个问题：谢谢你确认我的假设，谢谢你提出了一个问题。我会留意的。
