There is an open-source javascript plugin that does just that, but for any browser - <a href="https://github.com/inorganik/debugout.js">debugout.js</a> 

Debugout.js records and save console.logs so your application can access them. Full disclosure, I wrote it. It formats different types appropriately, can handle nested objects and arrays, and can optionally put a timestamp next to each log. You can also toggle live-logging in one place, and without having to remove all your logging statements.

blocks|key|549367|text|要获得更好的日志文件(没有Chrome-debug的废话)，可以使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|549368|--enable-logging+--log-level=0|code-block|syntax|javascript|549369|而不是--v=1，这是太多的信息。|offset|length|style|CODE|549370|它仍然会提供错误和警告，就像你通常在Chrome控制台中看到的那样。|549371|2020年5月18日更新:实际上，我认为这不再是真的。无论这个日志级别是什么，我都找不到控制台消息。|549372|entityMap^0|0|0|3|5|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@$I|V|J|W|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

For better log file (without the Chrome-debug nonsense) use:

<pre><code>--enable-logging --log-level=0
</code></pre>

instead of
<code>--v=1</code> which is just too much info.

It will still provide the errors and warnings like you would typically see in the Chrome console.

update May 18, 2020: Actually, I think this is no longer true. I couldn't find the console messages within whatever this logging level is.

blocks|key|549482|text|在Linux+(至少)上，您可以在环境中设置CHROME_LOG_FILE，让chrome在每次运行时将控制台活动的日志写入指定的文件。每次启动chrome时，日志都会被覆盖。这样，如果您有一个运行chrome的自动会话，您不必更改启动chrome的方式，并且在会话结束后日志仍在那里。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|549483|导出CHROME_LOG_FILE=chrome.log|549484|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

On Linux (at least) you can set CHROME_LOG_FILE in the environment to have chrome write a log of the Console activity to the named file each time it runs. The log is overwritten every time chrome starts. This way, if you have an automated session that runs chrome, you don't have a to change the way chrome is started, and the log is there after the session ends.

export CHROME_LOG_FILE=chrome.log

blocks|key|766149|text|现在，用鼠标右键单击控制台日志中显示的任何项，然后选择另存为，然后将整个日志输出保存到计算机上的一个文件中，这一点非常容易。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|766150|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

the other solutions in this thread weren't working on my mac. Here's a logger that saves a string representation intermittently using ajax. use it with <code>console.save</code> instead of <code>console.log</code>

<pre class="lang-js prettyprint-override"><code>var logFileString="";
var maxLogLength=1024*128;

console.save=function(){
 var logArgs={};

 for(var i=0; i&lt;arguments.length; i++) logArgs['arg'+i]=arguments[i];
 console.log(logArgs);

 // keep a string representation of every log
 logFileString+=JSON.stringify(logArgs,null,2)+'\n';

 // save the string representation when it gets big
 if(logFileString.length&gt;maxLogLength){
 // send a copy in case race conditions change it mid-save
 saveLog(logFileString);
 logFileString="";
 }
};
</code></pre>

depending on what you need, you can save that string or just <code>console.log</code> it and copy and paste. here's an ajax for you in case you want to save it:

<pre class="lang-js prettyprint-override"><code>function saveLog(data){
 // do some ajax stuff with data.
 var xhttp = new XMLHttpRequest();

 xhttp.onreadystatechange = function(){
 if (this.readyState == 4 &amp;&amp; this.status == 200) {}
 }

 xhttp.open("POST", 'saveLog.php', true);
 xhttp.send(data);
}
</code></pre>

the <code>saveLog.php</code> should append the data to a log file somewhere. I didn't need that part so I'm not including it here. :)

Does anyone know of a way to save the console.log output in Chrome to a file? Or how to copy the text out of the console?

Say you are running a few hours of functional tests and you've got thousands of lines of console.log output in Chrome. How do you save it or export it?

有谁知道将Chrome中的console.log输出保存到文件的方法吗？或者如何将文本复制出控制台？假设你正在运行几个小时的功能测试，你在Chrome中得到了成千上万行的console.log输出。如何保存或导出？
