爬虫：爬取王者荣耀技能信息（代码和代码流程）

• 代码

• # 王者荣耀英雄信息获取 import time from selenium import webdriver from selenium.webdriver.common.by import By if __name__ == '__main__':     fp = open("./honorKing.txt", "w", encoding='utf8')     # 1、url     url = "https://pvp.qq.com/web201605/herolist.shtml"#页面url     # 2、发送请求     driver = webdriver.Edge()#采用edge浏览器     driver.get(url)#获取url     time.sleep(3)#防止被检测到爬虫爬取     # 3、获取想要的信息     # 获取页面信息     # driver.page_source     # 4、数据解析     li_list = driver.find_elements(By.XPATH, "//ul[@class='herolist clearfix']/li")#获取所有的li     hero_url_list = []#存储所有的跳转url数据     for li in li_list:         hero_url = li.find_element(By.XPATH, "a").get_attribute("href")#跳转的url         hero_url_list.append(hero_url)     # 句柄的问题  先把所有第一个页面的东西存起来     for url in hero_url_list:         time.sleep(3)#防止被检测到爬虫爬取         driver.get(url)         hero_name = driver.find_element(By.XPATH, "//h2[@class='cover-name']").text         div_list = driver.find_elements(By.XPATH, "//div[@class='skill-show']/div")# 拿到所有的技能信息         fp.write(hero_name + "\n")#写入角色名称         for div in div_list:             js = f'document.getElementsByClassName("show-list")[{div_list.index(div)}].style.display="block"'#解除技能信息被锁             driver.execute_script(js)             skill_name = div.find_element(By.XPATH, "p[1]/b").text             skill_desc = div.find_element(By.XPATH, "p[2]").text             fp.write(skill_name + "---->" + skill_desc + "\n")             print(skill_name, skill_desc)         # 只爬两个看看样例         # if hero_url_list.index(url) == 1:         #     break     driver.close() 

• 代码流程：

  • 获取页面的url

• 跳转到下一界面的url

• 找到希望得到的数据的位置

• 采用：f’document.getElementsByClassName(“show-list”)[{被锁位置}].style.display=“block”'，将不能同时出现的数据同时出现
