[英]selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally with ChromeDriver Chrome and Selenium
[英]selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally. Dockerize Flask Application
一個多星期以來,我一直在嘗試將 Flask 應用程序與 MongoDB 數據庫對接。 我的應用程序具有以下結構:
aplication
- db
Dockerfile
- web
app.py
Dockerfile
requirements.txt
docker-compose.yml
此應用程序使用 selenium、selenium-requests 和 BeautifulSoup 庫進行 web 抓取。 我一周以來遇到的問題是:
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
我一直在嘗試幾種不同的方法來制作應用程序的 Dockerfile,但我找不到真正有效的方法。
我的代碼如下:
from bs4 import BeautifulSoup
from seleniumrequests import Chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from flask import Flask, request, jsonify
from flask_restful import API, Resource
from pymongo import MongoClient
app = Flask(__name__)
api = api(app)
client = MongoClient("mongodb://db:27017")
db = client.FlaskAPI
users = db["users"]
chrome_options = Options()
chrome_options.add_argument("--headless")
webdriver = Chrome(executable_path='/usr/local/bin/chromedriver', options=chrome_options)
webdriver.get(self.url+'login')
webdriver.find_element_by_id("userName-id").send_keys(username)
webdriver.find_element_by_id("passWd-id").send_keys(password)
webdriver.find_element(By.XPATH, '//input[@value="Login"]').click()
soup = BeautifulSoup(self.webdriver.page_source, 'lxml')
data = ''
p = re.compile('var userParam=(.*);')
for script in soup.find_all("script", {"src":False}):
if p.search(script.string):
data = json.dumps(str(script.string))
data = remove_formatation_elements(data)
users.insert({"data": data})
FROM mongo:5.0.3
FROM python:3.8
WORKDIR /usr/src/app

和
version: '3.9'
services:
web:
build: './web'
ports:
- '5000:5000'
links:
- db
db:
build: './db'
使用 web 文件夾 dockerfile 在 /usr/local/bin 文件夾中創建 chromedriver,在 /usr/bin 文件夾中創建 google-chrome 和 google-chrome-stable 文件。
所以我不明白為什么,即使經過這么多不同的嘗試,我也無法讓這段代碼工作......有人可以幫我嗎?
此錯誤消息...
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
...意味着ChromeDriver無法啟動/生成新的WebBrowser ,即Chrome 瀏覽器session。
