无法像使用Selenium Python Instagram机器人一样击中

Question

你们！

[我正在通过修改其他人的脚本来学习Python，我的第一个迷你项目是一个Instagram机器人，它使用适用于Chrome的Selenium webdrive来评论和喜欢基于标签的帖子。这张单据是加里·维（Gary Vee）的作品，但我无法像上班一样（评论很棒！）。我使用Pyhton 3.8来运行它。

脚本是：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import random
import sys
import time

class GaryVee:
    username = 'xxxxxx'
    password = 'yyyyyy'

    hashtags = [
        'zzzzzz'
    ]

    comments = [
        'tttttttt'
    ]

    links = []

    price = 0.0

    def __init__(self):
        self.browser = webdriver.Chrome()
        self.login()
        self.hustle()

    def login(self):
        self.browser.get('https://www.instagram.com/accounts/login/?source=auth_switcher')
        time.sleep(2)

        username_field = self.browser.find_element_by_xpath("//input[@name='username']")
        username_field.clear()
        username_field.send_keys(self.username)
        time.sleep(1)

        password_field = self.browser.find_element_by_xpath("//input[@name='password']")
        password_field.clear()
        password_field.send_keys(self.password)
        time.sleep(1)

        login_button = self.browser.find_element_by_xpath("//button[@type='submit']")
        login_button.click()
        time.sleep(2)

    def hustle(self):
        self.getTopPosts()
        self.execute()
        self.finalize()

    def getTopPosts(self):
        for hashtag in self.hashtags:
            self.browser.get('https://www.instagram.com/explore/tags/' + hashtag +'/')
            time.sleep(2)

            links = self.browser.find_elements_by_tag_name('a')
            condition = lambda link: '.com/p/' in link.get_attribute('href')
            valid_links = list(filter(condition, links))

            for i in range(0, 9):
                link = valid_links[i].get_attribute('href')
                if link not in self.links:
                    self.links.append(link)

    def execute(self):
        for link in self.links:
            self.browser.get(link)
            time.sleep(1)

            self.browser.execute_script("window.scrollTo(0, document.body.scrollHeight);")
            time.sleep(1)

            self.comment()
            time.sleep(2)

            self.like()

            #self.price += 0.02
            #sleeptime = random.randint(18, 28)
            #time.sleep(sleeptime)

    def comment(self):
        comment_input = lambda: self.browser.find_element_by_tag_name('textarea')
        comment_input().click()
        comment_input().clear()

        comment = random.choice(self.comments)
        for letter in comment:
            comment_input().send_keys(letter)
            delay = random.randint(1, 7) / 30
            time.sleep(delay)

        comment_input().send_keys(Keys.RETURN)

    def like(self):
        like_button = lambda: self.browser.find_element_by_xpath('/html/body/div[3]/div[2]/div/article/div[2]/section[1]/span[1]/button/span')
        like_button().click()

    def finalize(self):
        print('You gave $' + str(self.price) + ' back to the community.')
        self.browser.close()
        sys.exit()

garyVee = GaryVee()

这是我在命令行中得到的：

  (Session info: chrome=80.0.3987.87)

我想我应该在like（self）中更改find​​_element函数（或其参数），但是即使在网上找到了很多示例之后，我也无法弄清楚那里有什么...

任何帮助将不胜感激！

谢谢，阿农

让我知道您是否知道这一点。我在同一个问题上苦苦挣扎。

sn：instagram是否可以检测硒？这里是关于它的讨论，但是我有点困惑，谢谢：
