Python 爬取QQ空间相册
项目背景
前几天看着QQ相册里的有些年代比较久远还是比较令人怀念的，于是我本想一键导出相册但却发现QQ相册并没有这个功能，还得自己写代码一键导出着实令人头疼，说做就做，还是直接搞吧。
网页分析
首先应该是找相册列表的接口，这个应该是比较容易找到，接口是https://user.qzone.qq.com/proxy/domain/photo.qzone.qq.com/fcgi-bin/fcg_list_album_v3而其参数中，我们可以剔出不必要的参数，最后剩下g_tk、hostUin、uin、inCharset、outCharset、pageNumModeSort、pageNumModeClass这几个参数值，其中g_tk为加密算法的g_tk值，hostUin和uin是登录QQ账号和被访问QQ账号，因为我们是在下载自己空间相册，所以这两个都是我们的QQ账号，inCharset、outCharset则是输入输出编码格式，这是固定的，pageNumModeSort、pageNumModeClass则是每页的相册信息，保持默认不变即可。

接下来应该是找相册图片列表的接口，这个也是比较容易找到，接口是https://h5.qzone.qq.com/proxy/domain/photo.qzone.qq.com/fcgi-bin/cgi_list_photo，这个接口最后也有一些参数，去掉不必要的参数，最后剩下g_tk、hostUin、uin、inCharset、outCharset、topicId、pageNum、page这几个参数，而前五个参数与上一个接口相同，而topicId对应的是相册的id，而pageNum和page则是每页相册数以及页码数，直接令pageNum等于该相册内照片数目，page等于0或者取消该参数，即可获得该相册全部照片数据。

在相册数据集中就会有每张照片所对应的信息，以及URL地址，我们则可以通过该URL链接下载我们所需要的照片，即接下来就可以写代码实现相关需求了。
爬取思路
根据以上分析，我们首先定义一个相关的类QQZonePictures，并初始化相关参数和属性。
def __init__(self, cookies=None, gtk=None, uin=None):
self.cookies = cookies
self.gtk = gtk
self.uin = uin
self.root = self.Mkdir_path(".//images//")
self.url_list = 'https://user.qzone.qq.com/proxy/domain/photo.qzone.qq.com/fcgi-bin/fcg_list_album_v3'
self.url_photo = 'https://h5.qzone.qq.com/proxy/domain/photo.qzone.qq.com/fcgi-bin/cgi_list_photo'
self.header = {
'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;'
'q=0.8,application/signed-exchange;v=b3;q=0.9',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'zh-CN,zh;q=0.9,en;q=0.8',
'cache-control': 'no-cache',
'cookie': self.cookies,
'pragma': 'no-cache',
'sec-fetch-dest': 'document',
'sec-fetch-mode': 'navigate',
'sec-fetch-site': 'none',
'sec-fetch-user': '?1',
'upgrade-insecure-requests': '1',
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) '
'AppleWebKit/537.36 (KHTML, like Gecko) '
'Chrome/80.0.3987.116 Safari/537.36',
}然后我们需要写两个方法分别对两个接口进行爬取，但是对两个接口爬取到的信息需要进行清洗才能够使用，所以我们创建了一个数据清洗的方法，对获取的数据进行清洗，并返回清洗后的数据字典。
def Clean_data(self, string):
response = string.replace(' ', '')
response = response.replace('\t', '')
response = response.replace('\n', '')
response = response.replace('false', '"false"')
response = response.replace('true', '"true"')
data = json.loads(response[10:-2])
return data
def Get_photo_lists(self):
param = {
'g_tk': self.gtk,
'hostUin': self.uin,
'uin': self.uin,
'inCharset': 'utf-8',
'outCharset': 'utf-8',
'pageNumModeSort': '40',
'pageNumModeClass': '15'
}
res = requests.get(self.url_list, headers=self.header, params=param)
Photo_lists_data = self.Clean_data(res.text)
return Photo_lists_data
def Get_photos(self, list_id, num):
param = {
'g_tk': self.gtk,
'hostUin': self.uin,
'uin': self.uin,
'inCharset': 'utf-8',
'outCharset': 'utf-8',
'topicId': list_id,
'pageNum': num,
}
res = requests.get(self.url_photo, headers=self.header, params=param)
Photos_data = self.Clean_data(res.text)
return Photos_data到此我们已经能够获取QQ空间所有的相册，以及所有相册中的照片信息，接下来就是对相册中的照片进行下载，我们需要创建一个生成路径文件夹的方法用于以及一个用于图片下载的方法。
def Mkdir_path(self, path):
if not os.path.exists(path):
os.mkdir(path)
return path
def Downloads(self, data):
file_name, count = data["data"]["topic"]['name'], 0
root = self.Mkdir_path(self.root + file_name + '//')
print(f"相册{file_name}开始下载...")
for photo in data["data"]["photoList"]:
path = root + f"image_{count}.jpg"
read = requests.get(photo['url'])
with open(path, 'wb') as file:
file.write(read.content)
print(f"image_{count}.jpg 下载成功")
count = count + 1
print(f"相册{file_name}下载完成...")最后，我们创建主方法，通过上述方法将整个QQ空间相册下载类中的方法和属性整合在一起。
def main(self):
photos_lists = self.Get_photo_lists()
for photos_list in photos_lists["data"]["albumListModeSort"]:
list_id = photos_list['id']
num = photos_list['total']
Photos_data = self.Get_photos(list_id, num)
self.Downloads(Photos_data)完整代码

QQ空间模拟登陆
虽然大家读完这篇博客已经清楚了，但是对于我给出的完整代码最后的g_tk、cookies、uin这三个参数可能还有较多的疑问，对于g_tk、cookies、uin的获取方法就要涉及到爬虫的模拟登陆，但是QQ空间的模拟登陆是比较复杂的，所以我提供三种解决方案，而这三种解决方案的代码实现将会在后续博客中进行详细描述的解析。
解决方案①
我们作为在查找接口时，已经获取过这三个参数g_tk、cookies、uin，所以手动登陆空间然后获取这些参数，手动输入后，便可直接运行上述程序。
解决方案②
通过代码用selenium来模拟人的操作来实现模拟登陆，具体来说就是先点击“账号密码登录”，定位账号、密码输入框并输入相应内容，定位登录按钮，点击登录，，要注意的是这个页面是有框架的，在源码里可以看到”login_frame”，所以要先切换到框架。

def login(self):

就是通过QQ空间的二维码登陆接口，利用手机QQ扫描二维码然后进行QQ空间的登陆，这种方法也是比较简单、高效、实用的方法，所以其实完整代码中的 QQZone() 类便是通过该方法进行登录的。
