Как скопировать лог ошибки

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?

This may or may not be helpful but on Windows you can read the console log using Event Tracing for Windows

Our integration tests are run in .NET so I use this method to add the console log to our test output. I’ve made a sample console project to demonstrate here: https://github.com/jkells/chrome-trace

—enable-logging —v=1 doesn’t seem to work on the latest version of Chrome.

There is another open-source tool which allows you to save all console.log output in a file on your server — JS LogFlush (plug!).

JS LogFlush is an integrated JavaScript logging solution which include:

• cross-browser UI-less replacement of console.log — on client side.
• log storage system — on server side.

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

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 console.save instead of console.log

var logFileString="";
var maxLogLength=1024*128;

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

  for(var i=0; i<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>maxLogLength){
    // send a copy in case race conditions change it mid-save
    saveLog(logFileString);
    logFileString="";
  }
};

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

function saveLog(data){
  // do some ajax stuff with data.
  var xhttp = new XMLHttpRequest();

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

  xhttp.open("POST", 'saveLog.php', true);
  xhttp.send(data);
}

the saveLog.php should append the data to a log file somewhere. I didn’t need that part so I’m not including it here.

This answer might seem specifically related, but specifically for Network Log, you can visit the following link.

The reason I’ve post this answer is because in my case, the console.log printed a long truncated text so I couldn’t get the value from the console. I solved by getting the api response I was printing directly from the network log.

chrome://net-export/

There you may see a similar windows to this, just press the Start Logging to Disk button and that’s it:

Create a batch file using below command and save it as ChromeDebug.bat in your desktop.

start chrome --enable-logging --v=1

Close all other Chrome tabs and windows.
Double click ChromeDebug.bat file which will open Chrome and a command prompt with Chrome icon in taskbar.
All the web application logs will be stored in below path.
Run the below path in Run command to open chrome log file

%LocalAppData%\Google\Chrome\User Data\chrome_debug.log

One approch is to convert results into string and convert that string data to blob and then to data url and make it downloadable using <a> tag and click()

// Convert string data to url
var results = { test1: 'result1', test2: 'result2' }
let blob = new Blob([JSON.stringify(results)], {type: 'text/plain'})
let url = URL.createObjectURL(blob)

// Create anchor tag
let downloadLink = document.createElement('a')
downloadLink.download = 'results.txt'
downloadLink.href = url

// Click to download file
downloadLink.click()
