Trouble choosing and uploading a pdf file using requests

I could upload it using selenium. This website is tricky. It has a hidden input that only appears upon hovering a button to upload.

Try this:

from selenium import webdriver
from time import sleep
from selenium.webdriver.common.by import By

from selenium.webdriver.support.select import Select
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains


login_url = 'https://jobs.commerzbank.com/index.php?ac=login'

driver = webdriver.Chrome()
driver.implicitly_wait(5)
driver.maximize_window()

driver.get(login_url)
driver.find_element(By.ID, 'nav_login').click()
driver.find_element(By.CSS_SELECTOR, 'div.popover-content #quick-login-username').send_keys('SmthShift_123')
driver.find_element(By.CSS_SELECTOR, 'div.popover-content #quick-login-password').send_keys('7/B!yzRd8wuK!N2')
driver.find_element(By.CSS_SELECTOR,"div.popover-content #quick_login_form button[type='submit']").click()

driver.get('https://jobs.commerzbank.com/index.php?ac=application&jobad_id=30670')
driver.find_element(By.CSS_SELECTOR, ".applicationform-tab[data-pagenumber='6']").click()

select = Select(
    WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "select#upload_category"))))
select.select_by_visible_text("Lebenslauf")
WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "input#upload_file")))

e = driver.find_element(By.CSS_SELECTOR, "input#upload_file")
# Hover over and wait for tooltip to appear
action = ActionChains(driver)
action.move_to_element_with_offset(e, 5, 5)
action.perform()
sleep(3)

# Now, let's search for a hidden input and send keys
e = driver.find_element(By.CSS_SELECTOR, "input[name='attachment']")
e.send_keys("/<path>/CV.pdf")

# And click to upload:
e = driver.find_element(By.CSS_SELECTOR, "input#start_file_upload_button")
e.click()

Hope, this will work for you as well. Good luck!

Solution1

js file has attachFfwAjaxUpload() function, to upload attachment file.

find(name, attrs, recursive, text, **kwargs) - match and return first object.

Ex.

import requests
from bs4 import BeautifulSoup

login_url = 'https://jobs.commerzbank.com/index.php?ac=login'
application_link = 'https://jobs.commerzbank.com/index.php?ac=application&jobad_id=30670'
target_link = 'https://jobs.commerzbank.com/index.php?ac=application&page=6'
upload_link = 'https://jobs.commerzbank.com/inc/candidate_attachments.php'

with requests.Session() as sessionObj:
    sessionObj.headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36'
    res = sessionObj.get(login_url)
    sauce = BeautifulSoup(res.text,"lxml")
    elem = {i['name']:i.get('value','') for i in sauce.select('input[name]')}
    elem['username'] = 'SmthShift_123'
    elem['password'] = '7/B!yzRd8wuK!N2'

    sessionObj.post(login_url,data=elem)
    sessionObj.get(application_link)
    resp = sessionObj.get(target_link)
    soup = BeautifulSoup(resp.text,"lxml")

    # get attachment form tag object
    form = soup.find("form", attrs={'action':'index.php'})
    payload = dict()

    # set upload category
    # you have four category option, values are 2, 1, 4 and 12, 
    # select one value option
    payload['category'] = '12'
    payload['application_token'] = form.find('input', 
                        attrs={'name':'application_token'}).get('value','')
    payload['action'] = 'upload'

    # you can see upload file attachment attachFfwAjaxUpload() function in 
    # frontend.min.js file in browser source tab between 38878 to 38903 lines
    print(payload)

    with open('CV.pdf', 'rb') as f:

        file = {"attachment": f}
        atteachment_response = sessionObj.post(upload_link, files=file, data=payload)

        # print post request response status code 
        print(atteachment_response.status_code)
        print(atteachment_response.text)

Solution2 - By selenium to upload file

from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By    
from selenium.webdriver.support.select import Select
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains

login_url = 'https://jobs.commerzbank.com/index.php?ac=login'
application_link = 'https://jobs.commerzbank.com/index.php?ac=application&jobad_id=30670'

driver = Chrome()
driver.implicitly_wait(5)
driver.maximize_window()
driver.get(login_url)

WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID,'login')))

# set username
username = driver.find_element(By.ID, 'login-username')
username.send_keys('SmthShift_123')

# set password
password = driver.find_element(By.ID, 'login-password')
password.send_keys('7/B!yzRd8wuK!N2')

# login
login = driver.find_element_by_xpath("//form[@id='login']//button[@type='submit']")
login.click()

# after login switched into target url
driver.get(application_link)
driver.find_element(By.CSS_SELECTOR, ".applicationform-tab[data-pagenumber='6']").click()

# wait and select upload category
select = Select(
    WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "upload_category"))))
select.select_by_value("12")

WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "upload_file")))

e = driver.find_element(By.ID, "upload_file")

action = ActionChains(driver)
action.move_to_element_with_offset(e, 5, 5)
action.perform()

# find attachment input tag by name
upload = driver.find_element(By.NAME, "attachment")

# set pdf file path
upload.send_keys("/CV.pdf")

# upload file
upload = driver.find_element(By.ID, "start_file_upload_button")
upload.click()
