How to download captcha image with Python Selenium and Requests

Selenium Requests download image

img = driver.find_element_by_xpath("//div[@id='MailRuConfirm']/div/div[18]/form/div[1]/div[2]/div[2]/div[2]/img")
src = img.get_attribute('src')
img = requests.get(src)
with open('captcha.jpg', 'wb') as f:
    f.write(img.content)

I get script execution timeout instead, dunno what the issue is.
selenium.common.exceptions.TimeoutException: Message: script timeout
(Session info: chrome=80.0.3987.163)
The element looks fine and it's equal to the captcha element so the script itself might be the issue.,

Below code will give you exact same image open in browser

`

Hit the url

    driver.get(link)

Paste captcha full xpath here

    ele_captcha = driver.find_element_by_xpath("/html/body/form/div[2]/div[3]/span/div[1]/div/span[3]/img")   

get the captcha as a base64 string

    img_captcha_base64 = driver.execute_async_script("""
        var ele = arguments[0], callback = arguments[1];
        ele.addEventListener('load', function fn(){
          ele.removeEventListener('load', fn, false);
          var cnv = document.createElement('canvas');
          cnv.width = this.width; cnv.height = this.height;
          cnv.getContext('2d').drawImage(this, 0, 0);
          callback(cnv.toDataURL('image/jpeg').substring(22));
        }, false);
        ele.dispatchEvent(new Event('load'));
        """, ele_captcha)

save the captcha to a file

    with open(r"captcha.jpg", 'wb') as f:
        f.write(base64.b64decode(img_captcha_base64))
        `

for height and width -->. cnv.width = ele.width; cnv.height = ele.height; check your original captcha image size by downloading to local.Sometime original image size and the image tag size are different in those cases you get cropped or incomplete image

As Shown Below

import base64
img_base64 = driver.execute_script("""
    var ele = arguments[0];
    var cnv = document.createElement('canvas');
    cnv.width = 215; cnv.height = 80;
    cnv.getContext('2d').drawImage(ele, 0, 0);
    return cnv.toDataURL('image/jpeg').substring(22);    
    """, driver.find_element_by_xpath("/html/body/form/div[2]/div[3]/span/div[1]/div/span[3]/img"))   #"/html/body/form/div[2]/div[3]/span[3]/div[1]/img"))
with open(r"image.jpg", 'wb') as f:
    f.write(base64.b64decode(img_base64)) 

Works just fine.

Works fine! Saved my life there!

I tried this but i get this error. Can you please tell me what can be the issue?

selenium.common.exceptions.JavascriptException: Message: javascript error: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The provided value is not of type '(CSSImageValue or HTMLCanvasElement or HTMLImageElement or HTMLVideoElement or ImageBitmap or OffscreenCanvas or SVGImageElement or VideoFrame)'.
