背景说明

感觉微信公众号算得是比较难爬的平台之一，不过一番折腾之后还是小有收获的。没有用Scrapy(估计爬太快也有反爬限制)，但后面会开始整理写一些实战出来。简单介绍下本次的开发环境：

python3
requests
psycopg2 (操作postgres数据库)

抓包分析

本次实战对抓取的公众号没有限制，但不同公众号每次抓取之前都要进行分析。打开Fiddler，将手机配置好相关代理，为避免干扰过多，这里给Fiddler加个过滤规则，只需要指定微信域名mp.weixin.qq.com就好：

Fiddler配置Filter规则

平时关注的公众号也比较多，本次实战以“36氪”公众号为例，继续往下看：

“36氪”公众号

公众号右上角 -> 全部消息

在公众号主页，右上角有三个实心圆点，点击进入消息界面，下滑找到并点击“全部消息”，往下请求加载几次历史文章，然后回到Fiddler界面，不出意外的话应该可以看到这几次请求，可以看到返回的数据是json格式的，同时文章数据是以json字符串的形式定义在general_msg_list字段中：

公众号文章列表抓包请求

分析文章列表接口

把请求URL和Cookie贴上来进行分析：

https://mp.weixin.qq.com/mp/profile_ext?action=getmsg&__biz=MzI2NDk5NzA0Mw==&f=json&offset=10&count=10&is_ok=1&scene=126&uin=777&key=777&pass_ticket=QhOypNwH5dAr5w6UgMjyBrTSOdMEUT86vWc73GANoziWFl8xJd1hIMbMZ82KgCpN&wxtoken=&appmsg_token=971_LwY7Z%252BFBoaEv5z8k_dFWfJkdySbNkMR4OmFxNw~~&x5=1&f=json

下面把重要的参数说明一下，没提到的说明就不那么重要了：

__biz：相当于是当前公众号的id(唯一固定标志)
offset：文章数据接口请求偏移量标志(从0开始)，每次返回的json数据中会有下一次请求的offset，注意这里并不是按某些规则递增的
count：每次请求的数据量(亲测最多可以是10)
pass_ticket：可以理解是请求票据，而且隔一段时间后(大概几个小时)就会过期，这也是为什么微信公众号比较难按固定规则进行抓取的原因
appmsg_token：同样理解为非固定有过期策略的票据
Cookie：使用的时候可以把整段贴上去，但最少仅需要wap_sid2这部分

是不是感觉有点麻烦，毕竟不是要搞大规模专业的爬虫，所以单就一个公众号这么分析下来，还是可以往下继续的，贴上截取的一段json数据，用于设计文章数据表：

{
"ret": 0,
"errmsg": "ok",
"msg_count": 10,
"can_msg_continue": 1,
"general_msg_list": "{\"list\":[{\"comm_msg_info\":{\"id\":1000005700,\"type\":49,\"datetime\":1535100943,\"fakeid\":\"3264997043\",\"status\":2,\"content\":\"\"},\"app_msg_ext_info\":{\"title\":\"金融危机又十年：钱荒之下，二手基金迎来高光时刻\",\"digest\":\"退出永远是基金的主旋律。\",\"content\":\"\",\"fileid\":100034824,\"content_url\":\"http:\\/\\/mp.weixin.qq.com\\/s?__biz=MzI2NDk5NzA0Mw==&mid=2247518479&idx=1&sn=124ab52f7478c1069a6b4592cdf3c5f5&chksm=eaa6d8d3ddd151c5bb95a7ae118de6d080023246aa0a419e1d53bfe48a8d9a77e52b752d9b80&scene=27#wechat_redirect\",\"source_url\":\"\",\"cover\":\"http:\\/\\/mmbiz.qpic.cn\\/mmbiz_jpg\\/QicyPhNHD5vYgdpprkibtnWCAN7l4ZaqibKvopNyCWWLQAwX7QpzWicnQSVfcBZmPrR5YuHS45JIUzVjb0dZTiaLPyA\\/0?wx_fmt=jpeg\",\"subtype\":9,\"is_multi\":0,\"multi_app_msg_item_list\":[],\"author\":\"石亚琼\",\"copyright_stat\":11,\"duration\":0,\"del_flag\":1,\"item_show_type\":0,\"audio_fileid\":0,\"play_url\":\"\",\"malicious_title_reason_id\":0,\"malicious_content_type\":0}}]}",
"next_offset": 20,
"video_count": 1,
"use_video_tab": 1,
"real_type": 0
}

可以简单抽取想要的数据，这里将文章表结构定义如下，顺便贴上建表的SQL语句：

文章数据表

分析文章评论接口

获取评论的思路大致是一样的，只是会更加麻烦一点。首先在手机端点开一篇有评论的文章，然后查看Fiddler抓取的请求：

公众号文章评论

公众号文章评论接口抓包请求

提取其中的URL和Cookie再次分析：

https://mp.weixin.qq.com/mp/appmsg_comment?action=getcomment&scene=0&__biz=MzI2NDk5NzA0Mw==&appmsgid=2247518723&idx=1&comment_id=433253969406607362&offset=0&limit=100&uin=777&key=777&pass_ticket=NDndxxaZ7p6Z9PYulWpLqMbI0i3ULFeCPIHBFu1sf5pX2IhkGfyxZ6b9JieSYRUy&wxtoken=777&devicetype=android-26&clientversion=26070237&appmsg_token=971_dLK7htA1j8LbMUk8pvJKRlC_o218HEgwDbS9uARPOyQ34_vfXv3iDstqYnq2gAyze1dBKm4ZMTlKeyfx&x5=1&f=json
Cookie: pgv_pvid=2027337976; pgv_info=ssid=s3015512850; rewardsn=; wxuin=2089823341; devicetype=android-26; version=26070237; lang=zh_CN; pass_ticket=NDndxxaZ7p6Z9PYulWpLqMbI0i3ULFeCPIHBFu1sf5pX2IhkGfyxZ6b9JieSYRUy; wap_sid2=CO3YwOQHEogBdENPSVdaS3pHOWc1V2QzY1NvZG9PYk1DMndPS3NfbGlHM0Vfal8zLU9kcUdkWTQxdUYwckFBT3RZM1VYUXFaWkFad3NVaWFXZ28zbEFIQ2pTa1lqZktfb01vcGdPLTQ0aGdJQ2xOSXoxTVFvNUg3SVpBMV9GRU1lbnotci1MWWl5d01BQUF+fjCj45PcBTgNQAE=; wxtokenkey=777

接着分析参数：

__biz：同上
pass_ticket：同上
Cookie：同上
offset和limit：代表偏移量和请求数量，由于公众号评论最多展示100条，所以这两个参数也不用改它
comment_id：获取文章评论数据的标记id，固定但需要从当前文章结构(Html)解析提取
appmsgid：票据id，非固定每次需要从当前文章结构(Html)解析提取
appmsg_token：票据token，非固定每次需要从当前文章结构(Html)解析提取

可以看到最后三个参数要解析html获取(当初真的找了好久才想到看文章网页结构)。从文章请求接口可以获得文章地址，对应上面的content_url字段，但请求该地址前仍需要对url做相关处理，不然上面三个参数会有缺失，也就获取不到后面评论内容：

def _parse_article_detail(self, content_url, article_id):
"""从文章页提取相关参数用于获取评论,article_id是已保存的文章id"""
try:
api = content_url.replace('amp;', '').replace('#wechat_redirect', '').replace('http', 'https')
html = requests.get(api, headers=self.headers).text
except:
print('获取评论失败' + content_url)
else:
# group(0) is current line
str_comment = re.search(r'var comment_id = "(.*)" \|\| "(.*)" \* 1;', html)
str_msg = re.search(r"var appmsgid = '' \|\| '(.*)'\|\|", html)
str_token = re.search(r'window.appmsg_token = "(.*)";', html)
if str_comment and str_msg and str_token:
comment_id = str_comment.group(1) # 评论id(固定)
app_msg_id = str_msg.group(1) # 票据id(非固定)
appmsg_token = str_token.group(1) # 票据token(非固定)

再回来看该接口返回的json数据，分析结构后然后定义数据表(含SQL)：

文章评论数据表

-- Table structure for tb_article_comment
-- ----------------------------
DROP TABLE IF EXISTS "public"."tb_article_comment";
CREATE TABLE "public"."tb_article_comment" (

);

最后展示下数据库里的数据，单线程爬的慢而且又没这方面的数据需求，所以也只是随便试了下手：

有时候写爬虫是个细心活，如果觉得太麻烦的话，推荐了解下WechatSogou这个工具。有问题的欢迎底部留言讨论。
