此次爬虫要实现的是爬取某个微博用户的关注和粉丝的用户公开基本信息，包括用户爱称、快手id、粉丝粉丝qq说说赞平台墨言代刷网性别、微博所在地和其粉丝数目，链接然后将爬取出来的抖音点赞代刷数据保存在MongoDB数据库中，最后再生成几个图表来简单剖析一下我们得到的快手数据。

具体步骤：

这里我们选定的粉丝粉丝爬取站点是，此站点是微博qq说说赞平台墨言代刷网微博移动端的站点，我们可以直接查看某个用户的链接微博，比如。抖音点赞代刷

然后查看其关注的快手用户微博粉丝链接，打开开发者工具，粉丝粉丝切换到XHR过滤器，微博一直下拉列表，链接就会听到有好多的Ajax恳求。这些恳求的类型是Get类型，返回结果是Json格式，展开以后才能看见有好多用户的信息。

这些恳求有两个参数，containerid和page，通过改变page的数值，我们能够得到更多的恳求了。获取其粉丝的用户信息的步骤是一样的，除了恳求的链接不同之外，参数也不同，修改一下就可以了。

由于这种恳求返回的结果里只有用户的名称和id等信息，并没有包含用户的性别等基本资料，所以我们点进某个人的微博，然后查看其基本资料，比如这个，打开开发者工具，可以找到下边这个恳求：

由于这个人的id是6857214856，因此我们可以发觉当我们得到一个人的id的时侯，就可以构造获取基本资料的链接和参数了，相关代码如下（uid就是用户的id）：

1 uid_str = "230283" + str(uid) 2 url = "https://m.weibo.cn/api/container/getIndex?containerid={ }_-_INFO&title=%E5%9F%BA%E6%9C%AC%E8%B5%84%E6%96%99&luicode=10000011&lfid={ }&featurecode=10000326".format(uid_str, uid_str) 3 data = {  4     "containerid": "{ }_-_INFO".format(uid_str), 5     "title": "基本资料", 6     "luicode": 10000011, 7     "lfid": int(uid_str), 8     "featurecode": 10000326 9 }

然后这个返回的结果也是Json格式，提取上去就很方便，因为很多人的基本资料都不怎样全，所以我提取了用户爱称、性别、所在地和其粉丝数目。而且由于一些帐号并非个人帐号，就没有性别信息，对于那些帐号，我选择将其性别设置为女性。不过在爬取的时侯微博粉丝链接，我发觉一个问题，就是当页数超过250的时侯，返回的结果就早已没有内容了，也就是说这个方式最多只能爬250页。对于爬取出来的用户信息，全都保存在MongoDB数据库中，然后在爬取结束以后，读取这种信息并勾画了几个图表，分别勾画了男女比列扇形图、用户所在地分布图和用户的粉丝数目柱状图。

主要代码：

由于第一页返回的结果和其他页返回的结果格式是不同的，所以要分别进行解析，而且由于部份结果的json格式不同，所以可能报错，因此采用了try…except…把出错缘由复印下来。

爬取第一页并解析的代码如下：

1 def get_and_parse1(url): 2     res = requests.get(url) 3     cards = res.json()['data']['cards'] 4     info_list = [] 5     try: 6         for i in cards: 7             if "title" not in i: 8                 for j in i['card_group'][1]['users']: 9                     user_name = j['screen_name']  # 用户名10                     user_id = j['id']  # 用户id11                     fans_count = j['followers_count']  # 粉丝数量12                     sex, add = get_user_info(user_id)13                     info = { 14                         "用户名": user_name,15                         "性别": sex,16                         "所在地": add,17                         "粉丝数": fans_count,18                     }19                     info_list.append(info)20             else:21                 for j in i['card_group']:22                     user_name = j['user']['screen_name']  # 用户名23                     user_id = j['user']['id']  # 用户id24                     fans_count = j['user']['followers_count']  # 粉丝数量25                     sex, add = get_user_info(user_id)26                     info = { 27                         "用户名": user_name,28                         "性别": sex,29                         "所在地": add,30                         "粉丝数": fans_count,31                     }32                     info_list.append(info)33         if "followers" in url:34             print("第1页关注信息爬取完毕...")35         else:36             print("第1页粉丝信息爬取完毕...")37         save_info(info_list)38     except Exception as e:39         print(e)

爬取其他页并解析的代码如下：

1 def get_and_parse2(url, data): 2     res = requests.get(url, headers=get_random_ua(), data=data) 3     sleep(3) 4     info_list = [] 5     try: 6         if 'cards' in res.json()['data']: 7             card_group = res.json()['data']['cards'][0]['card_group'] 8         else: 9             card_group = res.json()['data']['cardlistInfo']['cards'][0]['card_group']10         for card in card_group:11             user_name = card['user']['screen_name']  # 用户名12             user_id = card['user']['id']  # 用户id13             fans_count = card['user']['followers_count']  # 粉丝数量14             sex, add = get_user_info(user_id)15             info = { 16                 "用户名": user_name,17                 "性别": sex,18                 "所在地": add,19                 "粉丝数": fans_count,20             }21             info_list.append(info)22         if "page" in data:23             print("第{ }页关注信息爬取完毕...".format(data['page']))24         else:25             print("第{ }页粉丝信息爬取完毕...".format(data['since_id']))26         save_info(info_list)27     except Exception as e:28         print(e)

运行结果：

在运行的时侯可能会出现各种各样的错误，有的时侯返回结果为空，有的时侯解析出错，不过还是能成功爬取大部分数据的，这里就放一下最后生成的三张图片吧。
