[英]Download csv file from https tableau server with python using request and basic authentication
[英]Using WGET or Python to download and rename attachments from CSV requiring basic authentication
我刮了一個正在使用的票務網站,現在有一個CSV文件,看起來像這樣:ID,Attachment_URL,Ticket_URL。 我現在需要做的是下載每個附件,並使用Ticket_URL重命名該文件。 我的主要問題是,導航到Attachment_URL時,必須使用基本身份驗證,然后將您重定向到aws s3鏈接。 我已經能夠使用wget下載單個文件,但無法遍歷整個列表(約35k行),而且我不確定如何將文件命名為ticket_id。 任何意見,將不勝感激。
得到它了。
要打開已認證的會話:
# -*- coding: utf-8 -*-
import requests
import re
from bs4 import BeautifulSoup
import csv
import pandas as pd
import time
s = requests.session()
payload = {
'user': '',
'pw': ''
}
s.post('login.url.here', data=payload)
for i in range(1, 6000):
testURL = s.get(
'https://urlhere.com/efw/stuff&page={}'.format(i))
soup = BeautifulSoup(testURL.content)
table = soup.find("table", {"class": "table-striped"})
table_body = table.find('tbody')
rows = table_body.find_all('tr')[1:]
print "The current page is: " + str(i)
for row in rows:
cols = row.find_all('a', attrs={'href': re.compile("^/helpdesk/")})
# time.sleep(1)
with open('fd.csv', 'a') as f:
writer = csv.writer(f)
writer.writerow(cols)
print cols
print cols
然后,我清理了R中的鏈接並下載了文件。
