我正在尝试使用 chrome webdriver 用 selenium 抓取 Instagram。我需要获取 XHR 响应信息，我尝试了“browsermob-proxy”，但该信息还不够：

server = Server("/home/doruk/Downloads/browsermob-proxy 2.1.4/bin/browsermob-proxy")
server.start()
time.sleep(1)
proxy = server.create_proxy()
time.sleep(1)

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--proxy-server={0}".format(proxy.proxy)) 
browser = webdriver.Chrome(chrome_options=chrome_options)

##############################################
####This is output of proxy.har in json format.
 {
    "comment": "", 
    "serverIPAddress": "155.245.9.55", 
    "pageref": "", 
    "startedDateTime": "2018-05-21T16:44:41.053+03:00", 
    "cache": {}, 
    "request": {
      "comment": "", 
      "cookies": [], 
      "url": "https://scontent-sof1-1.cdninstagram.com/vp/e95312434013bc43a5c00c458b53022cb/5BC46751/t51.2885-19/s150x150/26432586_139925760144086_726193654523232256_n.jpg", 
      "queryString": [], 
      "headers": [], 
      "headersSize": 528, 
      "bodySize": 0, 
      "method": "GET", 
      "httpVersion": "HTTP/1.1"
    },

出现了，我需要它里面的信息。有没有办法处理这种情况？

我只需要“？query_hash =”的东西。

我已经做到了！我的诀窍就是等待页面的整个加载。不是我的 DOM 就绪状态页面继续加载。有一种方法可以消除任意睡眠并要求驱动程序真正完整地加载页面。我不记得代码...我必须搜索。

from browsermobproxy import Server
import json
from selenium import webdriver
import time

urle = "https://www.yoururl.com";

server = Server(path="./browsermob-proxy-2.1.4/bin/browsermob-proxy")
server.start()
proxy = server.create_proxy()
profile = webdriver.FirefoxProfile()
profile.set_proxy(proxy.selenium_proxy())
driver = webdriver.Firefox(firefox_profile=profile, executable_path='./geckodriver')
proxy.new_har(urle, options={'captureHeaders': True, 'captureContent':True})
driver.get(urle)
time.sleep(10)
result = json.dumps(proxy.har, ensure_ascii=False)
print result
proxy.stop()
driver.quit()
