環(huán)境:
案例思路:
先導(dǎo)入所需的模塊
import requestsimport parsel # 數(shù)據(jù)解析模塊import re
1.確定數(shù)據(jù)所在的鏈接地址(url) 逆向分析 網(wǎng)頁性質(zhì)(靜態(tài)網(wǎng)頁/動(dòng)態(tài)網(wǎng)頁)
打開開發(fā)者工具,播放一個(gè)音頻,在Madie里面可以找到一個(gè)數(shù)據(jù)包
復(fù)制URL,搜索
找到ID值
繼續(xù)搜索,找到請(qǐng)求頭參數(shù)
url = 'https://www.ximalaya.com/youshengshu/4256765/p{}/'.format(page)headers = { 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36'}
2.通過代碼發(fā)送url地址的請(qǐng)求
response = requests.get(url=url, headers=headers)html_data = response.text
3.解析數(shù)據(jù)(要的, 篩選不要的) 解析音頻的 id值
selector = parsel.Selector(html_data)lis = selector.xpath('//div[@class='sound-list _is']/ul/li')for li in lis: try: title = li.xpath('.//a/@title').get() + '.m4a' href = li.xpath('.//a/@href').get() # print(title, href) m4a_id = href.split('/')[-1] # print(href, m4a_id) # 發(fā)送指定id值json數(shù)據(jù)請(qǐng)求(src) json_url = 'https://www.ximalaya.com/revision/play/v1/audio?id={}&ptype=1'.format(m4a_id) json_data = requests.get(url=json_url, headers=headers).json() # print(json_data) # 提取音頻地址 m4a_url = json_data['data']['src'] # print(m4a_url) # 請(qǐng)求音頻數(shù)據(jù) m4a_data = requests.get(url=m4a_url, headers=headers).content new_title = change_title(title)
4.數(shù)據(jù)持久化(保存)
with open('video\\' + new_title, mode='wb') as f: f.write(m4a_data) print('保存完成:', title)
最后還要處理文件名非法字符
def change_title(title): pattern = re.compile(r'[\/\\\:\*\?\'\<\>\|]') # '/ \ : * ? ' < > |' new_title = re.sub(pattern, '_', title) # 替換為下劃線 return new_title
import reimport requestsimport parsel # 數(shù)據(jù)解析模塊def change_title(title): '''處理文件名非法字符的方法''' pattern = re.compile(r'[\/\\\:\*\?\'\<\>\|]') # '/ \ : * ? ' < > |' new_title = re.sub(pattern, '_', title) # 替換為下劃線 return new_titlefor page in range(13, 33): print('---------------正在爬取第{}頁的數(shù)據(jù)----------------'.format(page)) # 1.確定數(shù)據(jù)所在的鏈接地址(url) 逆向分析 網(wǎng)頁性質(zhì)(靜態(tài)網(wǎng)頁/動(dòng)態(tài)網(wǎng)頁) url = 'https://www.ximalaya.com/youshengshu/4256765/p{}/'.format(page) headers = { 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36'} # 2.通過代碼發(fā)送url地址的請(qǐng)求 response = requests.get(url=url, headers=headers) html_data = response.text # print(html_data) # 3.解析數(shù)據(jù)(要的, 篩選不要的) 解析音頻的 id值 selector = parsel.Selector(html_data) lis = selector.xpath('//div[@class='sound-list _is']/ul/li') for li in lis: try: title = li.xpath('.//a/@title').get() + '.m4a' href = li.xpath('.//a/@href').get() # print(title, href) m4a_id = href.split('/')[-1] # print(href, m4a_id) # 發(fā)送指定id值json數(shù)據(jù)請(qǐng)求(src) json_url = 'https://www.ximalaya.com/revision/play/v1/audio?id={}&ptype=1'.format(m4a_id) json_data = requests.get(url=json_url, headers=headers).json() # print(json_data) # 提取音頻地址 m4a_url = json_data['data']['src'] # print(m4a_url) # 請(qǐng)求音頻數(shù)據(jù) m4a_data = requests.get(url=m4a_url, headers=headers).content new_title = change_title(title) # print(new_title) # 4.數(shù)據(jù)持久化(保存) with open('video\\' + new_title, mode='wb') as f: f.write(m4a_data) print('保存完成:', title) except: pass
