爬网Selenium WebDriver时定义用户代理字符串

如何解决爬网Selenium WebDriver时定义用户代理字符串

我在初始化类时要执行的代码如下。执行以下错误时发生。

FirefoxOptions options = new FirefoxOptions();
                         ^
SyntaxError: invalid Syntax

请帮助使用useragent初始化webdriver。我希望我能避免机器人自然刮擦。使用：“ Mozilla / 5.0（Windows NT 6.1; Win64; x64; rv：47.0）Gecko / 20100101 Firefox / 47.0”作为代理

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.action_chains import ActionChains
from time import sleep
from bs4 import BeautifulSoup
import pandas as pd
class DataExtract:
    def __init__(self):
        FirefoxOptions options = new FirefoxOptions();
        String userAgent = ""Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0";
        options.addPreference("general.useragent.override",userAgent);
        WebDriver webDriver = new FirefoxDriver(options);
        options.add_argument('--allow-running-insecure-content')
        options.add_argument('--ignore-certificate-errors')
        self.driver = webdriver.PhantomJS(executable_path=r"C:/Pathtoexec/phantomjs/bin/phantomjs.exe")
        self.accept_untrusted_certs = True

解决方法

冲浪之后，我发现了一些对我有用的东西。请建议我如何检查是否已相应设置webagent。

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from time import sleep
from bs4 import BeautifulSoup
import pandas as pd

dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = (
"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/53 "
"(KHTML,like Gecko) Chrome/15.0.87")

driver = webdriver.PhantomJS(desired_capabilities=dcap,executable_path=r"C:/PathtoExec/phantomjs.exe")
driver.get("https://www.webpagecontainingtables.com")
soup=BeautifulSoup(driver.page_source,'lxml')
table = soup.find_all('table')[4]
df = pd.read_html(str(table),header=0)
print(df)
