小編給大家分享一下Python爬取微信公眾號文章和評論的案例，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
背景說明
感覺微信公眾號算得是比較難爬的平臺之一，不過一番折騰之后還是小有收獲的。沒有用Scrapy(估計爬太快也有反爬限制)，但后面會開始整理寫一些實戰出來。簡單介紹下本次的開發環境：
python3
requests
psycopg2 (操作postgres數據庫)
抓包分析
本次實戰對抓取的公眾號沒有限制，但不同公眾號每次抓取之前都要進行分析。打開Fiddler，將手機配置好相關代理，為避免干擾過多，這里給Fiddler加個過濾規則，只需要指定微信域名mp.weixin.qq.com就好：
Fiddler配置Filter規則
平時關注的公眾號也比較多，本次實戰以“36氪”公眾號為例，繼續往下看：
“36氪”公眾號
公眾號右上角 -> 全部消息
在公眾號主頁，右上角有三個實心圓點，點擊進入消息界面，下滑找到并點擊“全部消息”，往下請求加載幾次歷史文章，然后回到Fiddler界面，不出意外的話應該可以看到這幾次請求，可以看到返回的數據是json格式的，同時文章數據是以json字符串的形式定義在general_msg_list字段中：
公眾號文章列表抓包請求
分析文章列表接口
把請求URL和Cookie貼上來進行分析：
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 Cookie: pgv_pvid=2027337976; pgv_info=ssid=s3015512850; rewardsn=; wxtokenkey=777; wxuin=2089823341; devicetype=android-26; version=26070237; lang=zh_CN;pass_ticket=NDndxxaZ7p6Z9PYulWpLqMbI0i3ULFeCPIHBFu1sf5pX2IhkGfyxZ6b9JieSYRUy;wap_sid2=CO3YwOQHEogBQnN4VTNhNmxQWmc3UHI2U3kteWhUeVExZHFVMnN0QXlsbzVJRUJKc1pkdVFUU2Y5UzhSVEtOZmt1VVlYTkR4SEllQ2huejlTTThJWndMQzZfYUw2SldLVGVMQUthUjc3QWdVMUdoaGN0Nml2SU05cXR1dTN2RkhRUVd1V2Y3SFJ5d01BQUF+fjCB1pLcBTgNQJVO
下面把重要的參數說明一下，沒提到的說明就不那么重要了：
__biz：相當于是當前公眾號的id(唯一固定標志)
offset：文章數據接口請求偏移量標志(從0開始)，每次返回的json數據中會有下一次請求的offset，注意這里并不是按某些規則遞增的
count：每次請求的數據量(親測最多可以是10)
pass_ticket：可以理解是請求票據，而且隔一段時間后(大概幾個小時)就會過期，這也是為什么微信公眾號比較難按固定規則進行抓取的原因
appmsg_token：同樣理解為非固定有過期策略的票據
Cookie：使用的時候可以把整段貼上去，但最少僅需要wap_sid2這部分
是不是感覺有點麻煩，畢竟不是要搞大規模專業的爬蟲，所以單就一個公眾號這么分析下來，還是可以往下繼續的，貼上截取的一段json數據，用于設計文章數據表：
{
"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\":\"金融危機又十年：錢荒之下，二手基金迎來高光時刻\",\"digest\":\"退出永遠是基金的主旋律。\",\"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\":\"石亞瓊\",\"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
}可以簡單抽取想要的數據，這里將文章表結構定義如下，順便貼上建表的SQL語句：
文章數據表
-- ---------------------------- -- Table structure for tb_article -- ---------------------------- DROP TABLE IF EXISTS "public"."tb_article"; CREATE TABLE "public"."tb_article" ( "id" serial4 PRIMARY KEY, "msg_id" int8 NOT NULL, "title" varchar(200) COLLATE "pg_catalog"."default" NOT NULL, "author" varchar(20) COLLATE "pg_catalog"."default", "cover" varchar(500) COLLATE "pg_catalog"."default", "digest" varchar(200) COLLATE "pg_catalog"."default", "source_url" varchar(800) COLLATE "pg_catalog"."default", "content_url" varchar(600) COLLATE "pg_catalog"."default" NOT NULL, "post_time" timestamp(6), "create_time" timestamp(6) NOT NULL ) ; COMMENT ON COLUMN "public"."tb_article"."id" IS '自增主鍵'; COMMENT ON COLUMN "public"."tb_article"."msg_id" IS '消息id (唯一)'; COMMENT ON COLUMN "public"."tb_article"."title" IS '標題'; COMMENT ON COLUMN "public"."tb_article"."author" IS '作者'; COMMENT ON COLUMN "public"."tb_article"."cover" IS '封面圖'; COMMENT ON COLUMN "public"."tb_article"."digest" IS '關鍵字'; COMMENT ON COLUMN "public"."tb_article"."source_url" IS '原文地址'; COMMENT ON COLUMN "public"."tb_article"."content_url" IS '文章地址'; COMMENT ON COLUMN "public"."tb_article"."post_time" IS '發布時間'; COMMENT ON COLUMN "public"."tb_article"."create_time" IS '入庫時間'; COMMENT ON TABLE "public"."tb_article" IS '公眾號文章表'; -- ---------------------------- -- Indexes structure for table tb_article -- ---------------------------- CREATE UNIQUE INDEX "unique_msg_id" ON "public"."tb_article" USING btree ( "msg_id" "pg_catalog"."int8_ops" ASC NULLS LAST );

獲取評論的思路大致是一樣的，只是會更加麻煩一點。首先在手機端點開一篇有評論的文章，然后查看Fiddler抓取的請求：
公眾號文章評論
公眾號文章評論接口抓包請求
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
接著分析參數：
__biz：同上
pass_ticket：同上
Cookie：同上
offset和limit：代表偏移量和請求數量，由于公眾號評論最多展示100條，所以這兩個參數也不用改它
comment_id：獲取文章評論數據的標記id，固定但需要從當前文章結構(Html)解析提取
appmsgid：票據id，非固定每次需要從當前文章結構(Html)解析提取
appmsg_token：票據token，非固定每次需要從當前文章結構(Html)解析提取
可以看到最后三個參數要解析html獲取(當初真的找了好久才想到看文章網頁結構)。從文章請求接口可以獲得文章地址，對應上面的content_url字段，但請求該地址前仍需要對url做相關處理，不然上面三個參數會有缺失，也就獲取不到后面評論內容：
def _parse_article_detail(self, content_url, article_id):
"""從文章頁提取相關參數用于獲取評論,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('獲取評論失敗' + 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) # 評論id(固定)
app_msg_id = str_msg.group(1) # 票據id(非固定)
appmsg_token = str_token.group(1) # 票據token(非固定)再回來看該接口返回的json數據，分析結構后然后定義數據表(含SQL)：
文章評論數據表
-- ---------------------------- -- Table structure for tb_article_comment -- ---------------------------- DROP TABLE IF EXISTS "public"."tb_article_comment"; CREATE TABLE "public"."tb_article_comment" ( "id" serial4 PRIMARY KEY, "article_id" int4 NOT NULL, "comment_id" varchar(50) COLLATE "pg_catalog"."default", "nick_name" varchar(50) COLLATE "pg_catalog"."default" NOT NULL, "logo_url" varchar(300) COLLATE "pg_catalog"."default", "content_id" varchar(50) COLLATE "pg_catalog"."default" NOT NULL, "content" varchar(3000) COLLATE "pg_catalog"."default" NOT NULL, "like_num" int2, "comment_time" timestamp(6), "create_time" timestamp(6) NOT NULL ) ; COMMENT ON COLUMN "public"."tb_article_comment"."id" IS '自增主鍵'; COMMENT ON COLUMN "public"."tb_article_comment"."article_id" IS '文章外鍵id'; COMMENT ON COLUMN "public"."tb_article_comment"."comment_id" IS '評論接口id'; COMMENT ON COLUMN "public"."tb_article_comment"."nick_name" IS '用戶昵稱'; COMMENT ON COLUMN "public"."tb_article_comment"."logo_url" IS '頭像地址'; COMMENT ON COLUMN "public"."tb_article_comment"."content_id" IS '評論id (唯一)'; COMMENT ON COLUMN "public"."tb_article_comment"."content" IS '評論內容'; COMMENT ON COLUMN "public"."tb_article_comment"."like_num" IS '點贊數'; COMMENT ON COLUMN "public"."tb_article_comment"."comment_time" IS '評論時間'; COMMENT ON COLUMN "public"."tb_article_comment"."create_time" IS '入庫時間'; COMMENT ON TABLE "public"."tb_article_comment" IS '公眾號文章評論表'; -- ---------------------------- -- Indexes structure for table tb_article_comment -- ---------------------------- CREATE UNIQUE INDEX "unique_content_id" ON "public"."tb_article_comment" USING btree ( "content_id" COLLATE "pg_catalog"."default" "pg_catalog"."text_ops" ASC NULLS LAST );
萬里長征快到頭了，最后貼上這部分代碼，由于要先獲取文章地址，所以和上面獲取文章數據的代碼是一起的：
