How to set browser locale with chromedriver (Python)

Question

I am trying to set my browser locale by doing the following

options = webdriver.ChromeOptions()
options.add_argument('--lang=es')
driver = webdriver.Chrome(executable_path=driver_location, chrome_options=options)

When I browse to google the site is still displayed in english. Am I setting the "--lang" option wrong?

Answer 1

Not Working

I've tried the --lang=us option, as suggested, but also had no success using the code below. My webpages were still being downloaded with my default language (that's not en).

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('lang=en')
# options.add_argument('--lang=en') <- Tried this option as well
driver = webdriver.Chrome(chrome_options=options)

Working

After some research I found this gist that finally helped me. Their solution is to use the experimental option intl.accept_languages, as follows:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_experimental_option('prefs', {'intl.accept_languages': 'en,en_US'})
driver = webdriver.Chrome(chrome_options=options)

By doing that, pages started to be loaded with the language that I wanted.

Also, Google Chrome source code explains that this option will actually set the HTTP header Accept-Languages to the given value. What's exactly what I wanted to do.

Answer 2

Try and convert this to the Python equivalent. Check this link:

For Firefox:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference( "intl.accept_languages", "es" ); 
WebDriver driver = new FirefoxDriver(profile);

For Chrome:

ChromeOptions options = new ChromeOptions();
options.AddArguments("--lang=es");
ChromeDriver driver = new ChromeDriver(options);

Python equivalent that worked for me:

from selenium import webdriver
from time import sleep
driver_location = "res/chromedriver.exe"

options = webdriver.ChromeOptions()
options.add_argument('--lang=es')
driver = webdriver.Chrome(executable_path=driver_location, chrome_options=options)

driver.get("http://google.com")
sleep(3000)
driver.quit()

Answer 3

For Perl users here is the magic string:

Selenium::Chrome

my $driver = Selenium::Chrome->new( 'extra_capabilities' => { 'chromeOptions' => { 'prefs' => { 'intl.accept_languages' => 'es' } } });

Answer 4

The same thing happens when I switch Chrome's default language. There are two solutions I can think of - manually add the Accept-Language: es header, or go directly to Google's Spanish version of the homepage - driver.get("http://google.es")

You can add hl parameter to your query like https://www.google.com/?hl=es

Reference: https://sites.google.com/site/tomihasa/google-language-codes

you can define the web interface language to be English by adding hl=en to the end of the URL and after the change the URL will look like this: http://www.google.com/search?hl=en
