前景介紹
最近小伙伴們聽(tīng)歌的興趣大漲，網(wǎng)抑云綜合癥已經(jīng)遍布各地。
咱們?cè)賮?lái)抬高一波QQ音樂(lè)的熱度吧。
爬它！
目標(biāo)：歌手列表
任務(wù)：將A到Z的歌手以及全部頁(yè)數(shù)的歌存到本地和數(shù)據(jù)庫(kù)
觀察網(wǎng)頁(yè)url結(jié)構(gòu)
當(dāng)我們進(jìn)入網(wǎng)頁(yè)時(shí)發(fā)現(xiàn)此時(shí)是一個(gè)無(wú)參數(shù)的html網(wǎng)頁(yè)加載。
尋找我們想要拿到的位置尋找變化，但我們點(diǎn)擊A開(kāi)頭的網(wǎng)頁(yè)跳轉(zhuǎn)時(shí)，發(fā)現(xiàn) url 改變了，index 參數(shù)應(yīng)該是首字母，page 參數(shù)應(yīng)該是頁(yè)數(shù)變化。
這樣的話(huà)就減少一個(gè)找參數(shù)的時(shí)間啦。
找到XML
還是習(xí)慣的點(diǎn)開(kāi)檢查按鍵，找到首字母的作者提供的XML都需要什么參數(shù)，隨便點(diǎn)點(diǎn)A-Z發(fā)現(xiàn) XML 有一個(gè)請(qǐng)求蹦出來(lái)，里面返回了是個(gè) json 數(shù)據(jù)集，都點(diǎn)開(kāi)看看發(fā)現(xiàn)找到了每個(gè)作者的參數(shù)了。成功了一小半！
既然拿到了XML的網(wǎng)站，POST請(qǐng)求是一定的啦，接下來(lái)就該分析分析網(wǎng)站所需要的參數(shù)都是什么了，大致猜測(cè)一下，這么多數(shù)據(jù)中sign和data參數(shù)有點(diǎn)詭異，不像是正常的參數(shù)，加密參數(shù)也找到了。
破解sign加密參數(shù)
search 找一下sign都在哪里。因?yàn)閟ign應(yīng)該是個(gè)變量，所以說(shuō)在他后面加個(gè)=會(huì)查找的更精確一些。找到一個(gè)sign參數(shù)的位置，這應(yīng)該是個(gè)JavaScript代碼，那就應(yīng)該是這里面了。點(diǎn)進(jìn)去！
在JavaScript中找到了 sign 的位置，找到了一個(gè)JavaScript調(diào)用的網(wǎng)站，我們進(jìn)去看看是什么代碼在里面。
當(dāng)我們進(jìn)入網(wǎng)站之后，代碼有點(diǎn)亂我們?cè)诰€格式化一下看看里面是什么。
格式化代碼后發(fā)現(xiàn)這個(gè)里面含有sign參數(shù)。這個(gè)應(yīng)該是sign的加密算法，但是其中傳了一個(gè)參數(shù)進(jìn)入，我們需要了解一下他傳了什么參數(shù)，這樣我們的sign就出來(lái)了。
回到我們調(diào)用JavaScript網(wǎng)站的文件中，繼續(xù)往下看，我們發(fā)現(xiàn) sign 傳數(shù)值就在他的下部。我們看到了傳了個(gè)data給這個(gè)sign加密函數(shù)，點(diǎn)斷點(diǎn)看看data參數(shù)是什么。這data值看的好眼熟，這不是一開(kāi)始很奇怪那個(gè)參數(shù)data么。原來(lái)data弄出來(lái)了sign就能給出來(lái)的。
我們繼續(xù)找剛才的sign。點(diǎn)擊下一次跳轉(zhuǎn)我們發(fā)現(xiàn)我們找到另一個(gè)函數(shù)在里面，產(chǎn)生了一種疑惑，這個(gè)函數(shù)是做什么的，他為什么會(huì)跳向這里。
那我們先看看我們格式化出來(lái)的JavaScript到底能不能運(yùn)行吧。說(shuō)不定能運(yùn)行呢。
哦吼，能運(yùn)行，那就好辦了，看看他返回的參數(shù)到底是啥，在開(kāi)頭定義一個(gè)sign=null，將t返回給sign，再把sign打印出來(lái)。這是剛才的那個(gè)跳轉(zhuǎn)過(guò)去的方法。
原來(lái)如此，那我們將sign調(diào)用一下加個(gè)()，我們就能發(fā)現(xiàn)sign的值就出現(xiàn)了。但我們重復(fù)運(yùn)行發(fā)現(xiàn)我們無(wú)法得到他的加密值，因?yàn)檫@些都是一樣的。
回想我們剛才說(shuō)的話(huà)，他需要加一個(gè)data參數(shù)才可以獲得加密參數(shù)，那好再改一下。
首先我們先下載一個(gè)python調(diào)用JavaScript的庫(kù)。pip install PyExecJS
開(kāi)始寫(xiě)python代碼
import execjsdef get_sign(data):with open('a.js','r',encoding='utf-8') as f:text = f.read()js_data = execjs.compile(text)sign = js_data.call('get_sign',data)return signif __name__ == "__main__":data = '{"comm":{"ct":24,"cv":0},"singerList":{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":0,"cur_page":1}}}'sign = get_sign(data)print(data)????print(sign)
這是多次調(diào)用代碼的結(jié)果，發(fā)現(xiàn)data傳入成功了。
獲取歌手個(gè)數(shù)以及頁(yè)數(shù)
個(gè)數(shù)其實(shí)一開(kāi)始我們已經(jīng)拿到了，只不過(guò)那時(shí)候沒(méi)介紹，仔細(xì)的童鞋們應(yīng)該是看到了總數(shù)到底為多少個(gè)。我們點(diǎn)開(kāi)剛才的返回json結(jié)果就能看到total已經(jīng)給出來(lái)當(dāng)前的個(gè)數(shù)了。
現(xiàn)在該分析一下data參數(shù)，盲猜一通估計(jì)page和index都在data里面，要不然這個(gè)參數(shù)傳不上去呀。好的分析一下data到底有啥，咱拿過(guò)來(lái)看看。data里面看到了get_singer_list這個(gè)應(yīng)該是主要的東西。
這個(gè)是 A開(kāi)頭 第一頁(yè){"comm":{"ct":24,"cv":0},"singerList":{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":1,"sin":0,"cur_page":1}}}這個(gè)是 B開(kāi)頭 第一頁(yè){"comm":{"ct":24,"cv":0},"singerList":{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":0,"cur_page":1}}}這個(gè)是 B開(kāi)頭 第二頁(yè){"comm":{"ct":24,"cv":0},"singerList":{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":80,"cur_page":2}}}這個(gè)是 B開(kāi)頭 第三頁(yè){"comm":{"ct":24,"cv":0},"singerList":{"module":"Music.SingerListServer","method":"get_singer_list","param":{"area":-100,"sex":-100,"genre":-100,"index":2,"sin":160,"cur_page":3}}}
大致我們能分析出來(lái)。
字母的變化在 index 處，也就是A到Z以及后面的# 應(yīng)該是一共27個(gè)在里面，也就是index從1到27我們需要傳給他。
頁(yè)數(shù)的變化在 sin 這里，第一頁(yè)是0，第二頁(yè)就是80，第三頁(yè)是160，冷靜分析一下應(yīng)該是從0開(kāi)始以80為公差的等差數(shù)列。這個(gè)八十應(yīng)該是代表每一頁(yè)都含有八十個(gè)歌手。
cur_page應(yīng)該就是當(dāng)前頁(yè)數(shù)的意思。那咱們跟著sin一起改變。
那在這我們拿到了總數(shù)，加上每一頁(yè)總共能展示多少，因?yàn)槎喑鰜?lái)的個(gè)數(shù)需要占一頁(yè)才可以，我們使用向下取整。
獲取作者名字以及id號(hào)
我們根據(jù)上述寫(xiě)出來(lái)爬蟲(chóng)代碼后，就可以成功獲取 json 的返回值了，在里面我們能看到一個(gè)歌手的參數(shù)一共有五個(gè)，其中 singer_mid 和 singer_name 是我們所需要的。拿到這兩個(gè)值后可以進(jìn)入網(wǎng)站下載當(dāng)前歌手的歌曲。
尋找歌手的歌曲
我們隨意點(diǎn)進(jìn)去一個(gè)歌手，進(jìn)去后尋找XML的網(wǎng)站，我在這里找好了是 getSingerSong 變量。
在這里能獲取歌手的每首歌的所能拿到的結(jié)果。
我們看一下里面都需要什么參數(shù)，好像和上次的差不多哦。sign已經(jīng)獲取到了，data是給定的變量。單純的data有點(diǎn)變化，但問(wèn)題不大。那說(shuō)明還是能正常訪問(wèn)這個(gè)XML的。
data中有點(diǎn)變化的位置就是 singerMid ，這個(gè)參數(shù)我們?cè)趧偛乓呀?jīng)獲取到了。直接在里面引用一下就好了。begin的參數(shù)是一個(gè)歌手歌的頁(yè)數(shù)，num是一頁(yè)中包括多少歌曲。其實(shí)我們傳參數(shù)可以將這個(gè)參數(shù)改一下的。把num的值改到一個(gè)很大的值，我們就可以不需要改變begin的參數(shù)就能拿到所有的歌曲結(jié)果。
我們仔細(xì)找一下 json 里面的參數(shù)，點(diǎn)擊音樂(lè)鏈接進(jìn)入發(fā)現(xiàn)是https://y.qq.com/n/yqq/song/002MQlds19S8qy.html，我們能發(fā)現(xiàn)，在這個(gè)歌曲里面的 mid 參數(shù)就是每首歌的格式化位置。
尋找下載歌曲的m4a鏈接
我們點(diǎn)入播放中。尋找里面的m4a鏈接看看都包含什么參數(shù)，發(fā)現(xiàn)存在七個(gè)鏈接都是。但我們仔細(xì)一看歌曲的大小我們就會(huì)發(fā)現(xiàn)，前幾個(gè)都是有問(wèn)題的發(fā)包，一首歌怎么可能只有幾kb呢。毫不猶豫點(diǎn)進(jìn)去最后一個(gè)。
哦吼，這回參數(shù)不一樣了哦。那我們?cè)谥匦路治鲆幌孪掳蓜e懶了。
我們先查找一下他給出來(lái)的一些包，看看能不能找到一個(gè)非加密參數(shù)出來(lái)。
果然，功夫不負(fù)有心人。vkey 就不是個(gè)加密參數(shù)！
破解參數(shù)前先學(xué)會(huì)"投機(jī)取巧"
我不知道剛才有沒(méi)有仔細(xì)看這個(gè)位置，發(fā)現(xiàn)這個(gè)也是個(gè)很長(zhǎng)的字符串，但是他很特殊，特殊到它和m4a的url是一樣的。
為了讓你們看到，我在這里把這倆寫(xiě)出來(lái)，發(fā)現(xiàn)到他們差了什么。不變的字符串前綴。。

那我們先看看vkey到底需要什么參數(shù)給進(jìn)去。其他參數(shù)還是都那些，還是差了一個(gè)data需要給進(jìn)去的。咱們分析一下data都需要給啥吧。
?{"req":{"module":"CDN.SrfCdnDispatchServer","method":"GetCdnDispatch","param":{"guid":"9232644380","calltype":0,"userip":""}},"req_0":{"module":"vkey.GetVkeyServer","method":"CgiGetVkey","param":{"guid":"9232644380","songmid":["002MQlds19S8qy"],"songtype":[0],"uin":"0","loginflag":1,"platform":"20"}},"comm":{"uin":0,"format":"json","ct":24,"cv":0}}大致分析了一下
guid是個(gè)無(wú)用參數(shù)。
songmid 是歌曲的 mid，我們剛才已經(jīng)獲取了
uin 需要加入一個(gè)qq號(hào)才可以獲取，如果未登陸默認(rèn)為0
其他都是定死的參數(shù)
m4a文件是一個(gè)二進(jìn)制文件。所以說(shuō)我們寫(xiě)代碼一定要寫(xiě)入二進(jìn)制文件才可以。
代碼優(yōu)化
因?yàn)閿?shù)據(jù)量過(guò)大，日常存入數(shù)據(jù)庫(kù)
因?yàn)閿?shù)據(jù)下載量大，使用多進(jìn)程爬取。將A-Z及#各開(kāi)一個(gè)進(jìn)程
防止存入數(shù)據(jù)庫(kù)在多線程階段同時(shí)占用，上鎖
