问题：指定类型筛选随机电影时触发AttributeError
开发一款可推送随机电影的Telegram Bot（当前控制台测试，后续重构），全随机电影功能正常，但按指定类型筛选时出现异常，报错信息如下：

问题原因
- 类型键存在多余空格：
genres字典中'Anime'对应的键是'genre_1750 '（末尾带空格），但HTML中li的class是genre_1750（无空格），导致Selenium无法找到目标元素，后续未触发正确的筛选，页面没有加载出指定类型的电影内容，BeautifulSoup解析后找不到poster等元素，触发NoneType错误。 - 缺少页面等待机制：点击类型列表、复选框后，页面可能未完全加载就获取源码，导致soup内容不完整，无法提取电影信息。
- 复选框定位错误：直接点击li元素而非内部的input复选框，可能未触发实际的筛选状态变更。
- 逻辑冗余与异常缺失：代码中存在无意义的赋值语句，且未对
find方法的返回值做None判断，一旦元素找不到就直接崩溃。
修复方案
1. 修正类型字典的键
移除genres字典中键的多余空格，确保与HTML中的class完全匹配：
self.genres = { 'genre_1750': 'Anime', 'genre_22': 'biography', 'genre_3': 'action movie', 'genre_13': 'Western', 'genre_19': 'Military', 'genre_17': 'Detective', 'genre_456': 'Kids', 'genre_12': 'documentary', 'genre_8': 'Drama', 'genre_23': 'History', 'genre_6': 'Comedy', 'genre_15': 'short film', 'genre_16': 'Crime', 'genre_7': 'Melodrama', 'genre_21': 'Music', 'genre_14': 'Cartoon', 'genre_9': 'Musical', 'genre_10': 'Adventure', 'genre_11': 'Family', 'genre_24': 'Sport', 'genre_4': 'Thriller', 'genre_1': 'Horror', 'genre_2': 'Fantastic', 'genre_18': 'Film-Noir', 'genre_5': 'Fantasy' }
2. 添加显式等待
引入WebDriverWait和expected_conditions，确保元素加载完成后再操作：
from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC
3. 修正复选框定位与操作逻辑
在get_rnd_gener_movie中，先等待类型列表展开，再定位li下的input复选框并点击：
def get_rnd_gener_movie(self): genre_key = self.find_user_genre(user_input) if not genre_key: print("No Same Genre") return None self.list.click() # 等待类型列表展开 WebDriverWait(self.driver, 10).until( EC.visibility_of_element_located((By.ID, "genreList")) ) # 定位li元素，再找内部的复选框 li_element = self.driver.find_element(By.CLASS_NAME, genre_key) checkbox = li_element.find_element(By.TAG_NAME, "input") checkbox.click() self.button.click() # 等待电影内容加载完成 WebDriverWait(self.driver, 10).until( EC.visibility_of_element_located((By.CLASS_NAME, "poster")) ) self.new_html = self.driver.page_source self.soup = BeautifulSoup(self.new_html, "lxml") self.driver.quit() return self.soup
4. 增加异常判断，避免NoneType崩溃
在get_full_rnd_movie_data中，对每个find结果做None判断：
def get_full_rnd_movie_data(self, genre=False): self.soup = None if not genre: self.soup = self.get_rnd_movie() elif genre: self.soup = self.get_rnd_gener_movie() if not self.soup: print("Failed to get page source") return self.poster_div = self.soup.find("div", class_="poster") if self.poster_div: img_tag = self.poster_div.find("img") if img_tag and "src" in img_tag.attrs: self.poster_img_href = img_tag["src"] self.poster_img = self.url_for_img + self.poster_img_href self.film_name_div = self.soup.find("div", class_="filmName") if self.film_name_div: name_tag = self.film_name_div.find("a") if name_tag: self.film_name = name_tag.text self.film_genre_div = self.soup.find("div", class_="gray") if self.film_genre_div: self.film_genre = self.film_genre_div.text.strip() self.film_rating_div = self.soup.find("div", class_="rating") if self.film_rating_div: self.film_rating_imb = self.film_rating_div.text.strip() self.film_desc_div = self.soup.find("div", class_="syn") if self.film_desc_div: self.film_desc = self.film_desc_div.text.strip()
