Insert value in searchbar, select autocomplete result and get value by bs4

Question

I am trying to use Beautiful Soup to read a value from a web page. The following steps are necessary:

1. go to the webpage: url = 'https://www.msci.com/our-solutions/esg-investing/esg-fund-ratings/funds/'

2. insert the ISIN in the searchbar

3. select the autocomplete-results from the container msci-ac-search-data-dropdown (click) 4. read the value from the "div class: ratingdata-outercircle esgratings-profile-header-green" to get the text: "ratingdata-fund-rating esg-fund-ratings-circle-aaa".

so far i have tried the following:

import requests
from bs4 import BeautifulSoup

isin = 'IE00B4L5Y983'

url = 'https://www.msci.com/our-solutions/esg-investing/esg-fund-ratings/funds/'
soup = BeautifulSoup( requests.get(url).content, 'html.parser' )

payload = {}
for i in soup.select('form[action="https://www.msci.com/search"] input[value]'):
    payload[i['name']] = i['value']
payload['UQ_txt'] = isin

Answer 1

Try:

import requests
from bs4 import BeautifulSoup

isin = "IE00B4L5Y983"
url = "https://www.msci.com/our-solutions/esg-investing/esg-fund-ratings"

headers = {
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0",
    "X-Requested-With": "XMLHttpRequest",
}

params = {
    "p_p_id": "esg_fund_ratings_profile",
    "p_p_lifecycle": "2",
    "p_p_state": "normal",
    "p_p_mode": "view",
    "p_p_resource_id": "searchFundRatingsProfiles",
    "p_p_cacheability": "cacheLevelPage",
    "_esg_fund_ratings_profile_keywords": isin,
}

data = requests.get(url, params=params, headers=headers).json()

params = {
    "p_p_id": "esg_fund_ratings_profile",
    "p_p_lifecycle": "2",
    "p_p_state": "normal",
    "p_p_mode": "view",
    "p_p_resource_id": "showEsgFundRatingsProfile",
    "p_p_cacheability": "cacheLevelPage",
    "_esg_fund_ratings_profile_fundShareClassId": data[0]["url"],
}

headers["Referer"] = "https://www.msci.com/our-solutions/esg-investing/esg-fund-ratings/funds/{}/{}".format(
    data[0]["encodedTitle"], data[0]["url"]
)

soup = BeautifulSoup(
    requests.get(url, params=params, headers=headers).content, "html.parser"
)
data = soup.select_one(".ratingdata-fund-rating")["class"]
print(data)

Prints:

['ratingdata-fund-rating', 'esg-fund-ratings-circle-aaa']
