摘要:但是別忘了,人的眼界不一樣,做事的決定自然會不同。,為直播間的房間號,為我發(fā)送的內(nèi)容。為時間戳,簽名也是加密的。很多人會問我為什么只會發(fā)實戰(zhàn)的案例教程,從來不發(fā)一些知識點或者軟件的使用教程。
目錄
告知:本人所有文章,禁止轉(zhuǎn)載。
大家好,我叫善念。連續(xù)更新了8篇原創(chuàng)文章了,可也見不到什么反響。也許是我發(fā)的文章內(nèi)容過于簡單,沒有什么價值,也許也是有一些運氣的成分,不懂得如何去運營。
但我都會堅持下去,萬一有一天它就爆發(fā)了呢?
這次給大家?guī)淼氖且粋€2500的爬蟲外包項目,在這里肯定有人說這個不值這么多,也有人會各種嘲諷。但是別忘了,人的眼界不一樣,做事的決定自然會不同。
如果2500能給你帶來25000的利潤,那么你會選擇毫不猶豫的支付嗎?話不多說,看聊天記錄,
還是挺久以前做的了。(我后面再給大家一一道來,暫時先看咱們的教程。)
進入目標(biāo)網(wǎng)站:目標(biāo)網(wǎng)站
?隨便進入一個分類,點擊進入某直播間
?當(dāng)我們點擊彈幕直播框時,它會要求咱們登錄賬號。這也實屬正常,沒辦法那咱們就登錄吧。
登錄成功后,咱們抓一下這個發(fā)送彈幕的包:
確實尷尬,我不知道發(fā)送什么,就說了句您好,沒想到小姐姐很驚訝的說您好,您也好......然后說聽完一首《飄向北方》就下播了......我不知道他下播了后,我還是否可以發(fā)送彈幕。
不管了,我先抽支煙看看小姐姐聽完這首歌再接著寫。
emmm,roomid為直播間的房間號,content為我發(fā)送的內(nèi)容。
roomid可以在url中看得到的,前面那個圖我沒截出來,自己看一下就知道了。
t為時間戳,sign簽名也是JavaScript加密的。其它值不變,自己發(fā)送兩次彈幕抓包對比一下就好了。
有人會奇怪你怎么知道t為時間戳......這玩意還需要說么,還是說一下吧,查找一下t的來源,我覺得向這種短的參數(shù),最好別直接搜t,你會搜出來一大堆的。我建議搜臨近的值sign,因為你提交的表單中有這么多的參數(shù),那么在js文件中基本也會有相對應(yīng)的參數(shù)的。
t:i意思是把i賦值給t,而
i = (new Date).getTime()?
?
?哦豁,沒學(xué)過前端的人就看不懂這個是啥意思了,這個其實就是JavaScript語法中的取現(xiàn)行時間。
?在我們的鬼鬼js調(diào)試工具看看效果:
?可以看到是它是一直在變化的,就像咱們的時間一樣一直在流逝變化。不懂什么是時間戳的自己去谷歌一下。
或者在咱們的控制臺也可以得到它:
既然它是利用JavaScript這么個語法生成的參數(shù),那么我們用Python如何實現(xiàn)?
OK,至此已經(jīng)解決第一個加密的參數(shù)。
接下來就是大頭菜了,咱們分析sign簽名是如何得到的:
好吧,很多位置參數(shù),壓根不知道是如何得來的但是可以看到它用到 i 這個參數(shù),也就是咱們的時間戳。
還是debug一下吧:?
?打個斷點,在瀏覽器上隨意發(fā)送一彈幕,發(fā)現(xiàn)g就是appkey是一個定值,c為一個字典,咱們要取的是c字典中data鍵所對應(yīng)的值:
是不是好熟悉,這不就是咱們post中的data的值么?那么就只剩下d了。?
d為一個字典,而咱們需要的是d里面的一個叫token鍵對應(yīng)的值:
?憑我經(jīng)驗,這個d根本不需咱們?nèi)フ宜鼞?yīng)該就是咱們的cookies,直接搜一下就完事了......
那么到此為止,咱們的所有參數(shù)都已經(jīng)分析完了,咱們開始測試一下:
發(fā)現(xiàn)缺少對象,emmmmm我三十歲的人都沒對象......這里毫無疑問就是少了h這個函數(shù)對象。
那么咱們?nèi)ソo它找出來即可
?
?點一下這個花括號,然后這樣子的話函數(shù)末也有出現(xiàn)這么一個橫杠,然后把JavaScript代碼摳下來再來測試:
OK,到此為止,咱們已經(jīng)完成了百分之五十了,為什么最核心的部分完成確只完成百分之五十呢?因為這個項目為三個程序:自動對接接嗎臺子注冊賬號、房間ID號采集篩選出主播在線的ID號、咱們這個的話就是關(guān)鍵的發(fā)送程序。

原創(chuàng)不易,謝謝大家支持。很多人會問我為什么只會發(fā)實戰(zhàn)的案例教程,從來不發(fā)一些知識點或者軟件的使用教程。
在這里我跟大家說明一下:基礎(chǔ)知識上哪都能學(xué),而我教你的是如何把你的基礎(chǔ)知識糅合組裝成一臺無所不及的坦克。
① 2000多本Python電子書(主流和經(jīng)典的書籍應(yīng)該都有了)
② Python標(biāo)準(zhǔn)庫資料(最全中文版)
③ 項目源碼(四五十個有趣且經(jīng)典的練手項目及源碼)
④ Python基礎(chǔ)入門、爬蟲、web開發(fā)、大數(shù)據(jù)分析方面的視頻(適合小白學(xué)習(xí))
⑤ Python學(xué)習(xí)路線圖(告別不入流的學(xué)習(xí))
