是否可以在请求模块中禁用InsecureRequestWarnings？

Question

本文解释了如何禁用urllib3中的警告，但我使用的是带有请求模块的session对象。出现警告是因为verify(ssl)参数设置为false，以便访问页。

例如。

url = "https://www.booking.com/searchresults.en-gb.html"

querystring = {"label":"gen173nr-1DCAEoggJCAlhYSDNiBW5vcmVmcgV1c19vcogBAZgBMbgBB8gBDdgBA-gBAfgBApICAXmoAgM","lang":"en-gb","sid":"5f9b0b3af27a0a0b48017c6c387d8224","track_lsso":"2","sb":"1","src":"searchresults","src_elem":"sb","error_url":"https://www.booking.com/searchresults.en-gb.html?label=gen173nr-1DCAEoggJCAlhYSDNiBW5vcmVmcgV1c19vcogBAZgBMbgBB8gBDdgBA-gBAfgBApICAXmoAgM;sid=5f9b0b3af27a0a0b48017c6c387d8224;class_interval=1;dest_id=30;dest_type=country;dtdisc=0;group_adults=1;group_children=0;inac=0;index_postcard=0;label_click=undef;mih=0;no_rooms=1;offset=0;postcard=0;raw_dest_type=country;room1=A;sb_price_type=total;src=searchresults;src_elem=sb;ss=" + country + ";ss_all=0;ssb=empty;sshis=0;ssne=" + country + ";ssne_untouched=" + country + "&;","ss":country,"ssne":country,"ssne_untouched":country,"dest_id":"30","dest_type":"country","checkin_monthday":"","checkin_month":"","checkin_year":"","checkout_monthday":"","checkout_month":"","checkout_year":"","room1":"A","no_rooms":"1","group_adults":"1","group_children":"0"}

Answer 1

可以使用urllib3.disable_warnings()禁用SSL、安全性和其他警告（请求在内部使用urllib3)。具体地说，如果将disable_warnings()与insecurerequestwarning对象一起使用，则可以抑制SSL验证警告。

import requests
from requests.packages import urllib3

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

url = "https://www.booking.com/searchresults.en-gb.html"
with requests.Session() as s:
    r = s.get(url, verify=False)
    html = r.text

请注意，禁用SSL对等验证(verify=false)可能是一个安全问题，因为它可能导致MITM攻击。
