Pythion的Selenium自动化测试之获取哔哩哔哩主播的头像以昵称命名保存到本地文件
效果图
方法1
通过接口获取
首先使用pip下载requests包
pip install requests
import requests # 通过接口获取请求的接口:想要获取网页的url url = 'https://api.live.bilibili.com/xlive/web-interface/v1/second/getList?platform=web&parent_area_id=1&area_id=0&sort_type=sort_type_152&page=1' # 发送get请求,获取返回数据 request = requests.get(url) # 保存图片的路径 dir = '../requests/bilibili/' # 将获取的数据转化为json文件并获取到图片的链接 info = request.json()['data']['list'] for i in info: # 将图片以主播的昵称命名 file = open(dir + '{}.png'.format(i['uname']), 'wb') # 将图片保存到之前的路径 file.write(requests.get(i['face']).content) # 关闭文件流 file.close()
方法2
通过html定位获取
首先使用pip下载requests和selenium包
pip install requests
pip install selenium
import requests from selenium import webdriver # 使用谷歌驱动打开谷歌浏览器 driver = webdriver.Chrome() # 访问哔哩哔哩直播页面 driver.get('https://live.bilibili.com/p/eden/area-tags?visit_id=2mwktlg4e2q0&areaId=0&parentAreaId=1') # 循环30次一次保存的头像图片 for i in range(1, 31): # xpth定位头像的位置 image_xpath = '/html/body/div[1]/div[3]/div/ul/li[{}]/a/div[1]/div/div'.format(i) # 获取位置的style属性值 image_style_value = driver.find_element_by_xpath(image_xpath).get_attribute('style') # 从style属性值中切片出图片的链接 image_url = image_style_value[image_style_value.find('h'):image_style_value.find('@'):1] # xpath定位昵称的位置 title_xpath = '/html/body/div[1]/div[3]/div/ul/li[{}]/a/div[2]/div[2]/div/span'.format(i) # 获取位置的title值 name_title_value = driver.find_element_by_xpath(title_xpath).get_attribute('title') print(image_url) # 发送get请求,获取返回数据 request = requests.get(image_url) # 保存图片的路径 file = open('D:Python Projects/requests/bilibili/{}.jpg'.format(name_title_value), 'wb') # 将图片保存到路径 file.write(request.content) # 关闭文件流 file.close()
最后,在为大家增加一个获取b站视频信息的操作代码
# coding:utf-8 import requests import json import time import pymysql import bs4 headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36' } result = [] def get_aid(page): url = 'https://search.bilibili.com/all?keyword=爬虫&from_source=nav_search&spm_id_from=333.851.b_696e7465726e6174696f6e616c486561646572.11' + '&page=' + str(page) response = requests.get(url, headers=headers, verify=False).text time.sleep(1) try: soup = bs4.BeautifulSoup(response, 'lxml').find('div', attrs={'id':'all-list'}).find('div', attrs={'class':'mixin-list'}) ul = soup.find('ul', attrs={'class':'video-list clearfix'}).find_all('li', attrs={'class':'video-item matrix'}) for item in ul: # print(item) info = item.find('div', attrs={'class': 'headline clearfix'}).find('span', attrs={'class': 'type avid'}).get_text() aid = info.replace('av', '') print(aid) result.append(aid) return result except: print('something is wrong') def get_contents(url): response = requests.get(url=url, headers=headers, verify=False).json() time.sleep(1) try: data_1 = response['data'] data = data_1['stat'] aid = data['aid'] view = data['view'] coin = data['coin'] like = data['like'] favorite = data['favorite'] share = data['share'] danmaku = data['danmaku'] print('视频编号', aid) print('观看数量', view) print('投币数量', coin) print('收藏数量', favorite) print('点赞数量', like) print('分享数量', share) print('弹幕数量', danmaku) except: print('------------') if __name__ == '__main__': for i in range(1, 50): result = get_aid(i) for i in result: url = 'https://api.bilibili.com/x/web-interface/view?aid=' + str(i) get_contents(url)
