How to enable “Preserve Log” in Network tab in Chr

问题:

How to enable "Preserve Log" in Network tools in Chrome developer tools by default? Everytime I press F12 and then select Network tab, I need to click preserve log checkbox to make it preserve request/responses. Is it possible to have it checked all the time by default?

By the way this feature works in "Firefox Developer" edition. When I click "Persist Logs" and close and then open the browser & DEV tools window again, it is still checked.

UPDATE - 6th March 2019

This will be fixed in Chrome 73. But if you want to try it before that then install Chrome Canary. It's working there. Thanks to the team for fixing it. Better late than never.

I have a small solution to that problem. I don't know whether it works correctly.First, click three dots->More tools -> Developer Tools. In that, click the three dots button(the name will be Customize and Control Dev Tools. In that, click settings.You will see a list of options with a main heading Preferences. From that, browse down to Console option. In that, just tick the option 'Preserve log upon navigation'. I guess this will solve your problem.

Automate keystrokes to set chrome with persistent logs on Network tab. Tested with Chrome 66.

• Make sure xdotool is installed
• Launch chrome
• Put the code below in a bash script chrome_auto.sh to send all the keys to: open a tab, dev tools, settings, set 'persistent logs', type the URL and hit enter.

#!/bin/bash

url="https://www.stackoverflow.com"
if [ -n "$1" ]; then
    url="$1"
fi

# find chrome window id
wid=$(xdotool search --class Chromium | tail -n1)
# build tab key sequence to set 'persistent logs'
tabkeys=$(for i in {1..24}; do t+="Tab ";done ;echo "$t space")
# base xdotool command
cmd="xdotool windowactivate --sync $wid"
# make chrome dance :-p
$cmd key ctrl+t
$cmd key F12
sleep 1
# open settings, move to desired option and select it
$cmd key F1 $tabkeys
sleep 1
# move cursor to URL box and type URL
$cmd key F6 type "$url"
$cmd key Return

Use the script as

./chrome_auto.sh "https://stackoverflow.com/questions/45133659"

• Also, chrome can be launched with dev tools open for every tab. If this is used, comment out the line with key F12

chromium --auto-open-devtools-for-tabs > /dev/null 2>&1 &
