Python爬蟲 - 抓取Tiktok小視頻

前言

好久沒更新了，更新一下
不廢話了

正文

確保電腦安裝了 charles / fiddler / wireshark 或其他能抓包的工具，然后在手機或者模擬器上配置好代理，記得安裝證書，接著開始抓包。

注：最好在 Android7.0 以下配置，7.0及以上版本不能抓https了，有點麻煩，推薦使用模擬器

首先安裝好 tiktok ，打開后翻幾個視頻，會發(fā)現(xiàn)抓包工具里出現(xiàn)一堆請求
charles
我們需要找到它小視頻請求的鏈接，經(jīng)過我個把小時的分析，找到了這個
charles
接下來需要模擬請求，看看他的請求頭

accept-encoding = gzip
user-agent = okhttp/3.10.0.1
method = GET

接著我發(fā)現(xiàn)雖然是GET請求，但是url鏈接后面有一串賊雞兒長的參數(shù)，wtm。。。
好吧，分析分析請求參數(shù)把，看著太費勁所以我寫了一個解析方法，解析成json格式，如下
 "type": "0",
 "max_cursor": "0",
 "min_cursor": "-1",
 "count": COUNT, # 加載個數(shù)
 "volume": "0.2",
 "pull_type": "2",
 "req_from": "",
 "gaid": "",
 "ad_user_agent": "Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+6.0.1%3B+MuMu+Build%2FV417IR%29", # 廣告ua
 "filter_warn": "0",
 "ts": TIMESTAMP[:-3], # 時間戳
 "js_sdk_version": "",
 "app_type": "normal",
 "os_api": "28",
 "device_type": "Xiaomi",
 "ssmix": "a",
 "manifest_version_code": "9999",
 "dpi": "240",
 "carrier_region": "JP", # 獲取的小視頻來源
 "region": "JP",
 "carrier_region_v2": "",
 "app_name": "trill",
 "version_name": "4.2.4",
 "ab_version": "4.2.4",
 "timezone_offset": "28800",
 "pass-route": "1",
 "pass-region": "1",
 "is_my_cn": "0",
 "fp":"",
 #"fp": "R2TrcrUtFMsrFYQZcrU1LSFeFWm1",
 "ac": "wifi",
 "update_version_code": "4240",
 "channel": "googleplay",
 "_rticket": TIMESTAMP, # 時間戳（保留毫秒）
 "device_platform": "android",
 "iid":"6678981313393919746", # 暫不知來源，必須有，不能更改
#     "iid": "6678981313393919746",
 "build_number": "9.5",
 "version_code": "424",
 "timezone_name": "Asia%2FShanghai",
 "openudid": "c55cd951e5464a56",
 "device_id": "6678979145927919106",
 "sys_region": "JP",
 "app_language": "zh-Hans",
 "resolution": RESOLUTION, # 畫質(zhì)
#     "resolution": "1280*720",
 "os_version": "9",
 "device_brand": "Android",
 "language": "jp",
 "aid": "1180", # 暫不知來源，必須有，不能更改
 "mcc_mnc": "",
 "as": "",
 "cp":"",
 "mas":""
 #"as": "a10548abb2087cfbe04299",
 #"cp": "8c8fc35c2606b9bae1Wc_g",
 #"mas": "019e07c3ae4fc3d6e172de9de34998f0ae9c9c4c2c0ca64666c6ec"
}
這里面有些能從字面意思看懂的就不多說了，主要看那后面幾個，fp、iid、aid、as、cp、mas 這里除了iid和aid這兩個參數(shù)不能更改以外，以他的參數(shù)隨便改，暫時也不知道 ? 和 ? 這兩個參數(shù)的來歷，保持不變即可
ok，模擬請求，代碼如下
import requests
?
headers = {
 "User-Agent": "okhttp/3.10.0.1",
 "Accpet-Encoding": "gzip"
}
?
url = "https://api-h2.tiktokv.com/aweme/v1/feed/"
?
def parse_url_params(param):
 """

 params = {}
 if '?' in param:
 p = param.split('?')[-1]
 ps = p.split('&')
 for i in ps:
 a = i.split('=')
 params.update({a[0]:'' if len(a) == 1 else a[1]})
 else:
 ps = param.split('&')
 for i in ps:
 a = i.split('=')
 params.update({a[0]:'' if len(a) == 1 else a[1]})
 return params
?
params = parse_url_params("type=0&max_cursor=0&min_cursor=-1&count=6&volume=0.2&pull_type=2&req_from&gaid&ad_user_agent=Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+6.0.1%3B+MuMu+Build%2FV417IR%29&filter_warn=0&ts=1555073922&js_sdk_version=&app_type=normal&os_api=23&device_type=MuMu&ssmix=a&manifest_version_code=9999&dpi=240&carrier_region=JP&region=CN&carrier_region_v2=&app_name=trill&version_name=4.2.4&ab_version=4.2.4&timezone_offset=28800&pass-route=1&pass-region=1&is_my_cn=0&fp=R2TrcrUtFMsrFYQZcrU1LSFeFWm1&ac=wifi&update_version_code=4240&channel=googleplay&_rticket=1555073923091&device_platform=android&iid=6678981313393919746&build_number=9.5&version_code=424&timezone_name=Asia%2FShanghai&openudid=c55cd951e5464a56&device_id=6678979145927919106&sys_region=CN&app_language=zh-Hans&resolution=1280*720&os_version=6.0.1&device_brand=Android&language=zh&aid=1180&mcc_mnc=&as=a10548abb2087cfbe04299&cp=8c8fc35c2606b9bae1Wc_g&mas=019e07c3ae4fc3d6e172de9de34998f0ae9c9c4c2c0ca64666c6ec")
?
resp = requests.get(url, headers=headers, params=params)
print(resp.json())
輸出一堆json內(nèi)容，由于內(nèi)容實在是太多，所以只看重點部分，下面是幾個
{'aweme_id': '6673431479185624322', 'desc': '', 'create_time': 1553847851,..., 'video': {'play_addr': {'uri': 'v07025860000bietc60src5j25b1epvg', 'url_list': [...], ...

這是一個視頻的部分json內(nèi)容，我們需要的有 create_time、video - play_addr - uri，emmm好像就這些，還有作者的信息我沒有貼上來自行分析吧，接著上全部代碼

最后

emmm，其實我把抓到的數(shù)據(jù)用flask寫成了一個小網(wǎng)站，由于我css賊垃圾，所以做的不是很美觀，項目地址: Flask-Tiktok
