python爬虫实战搞的是PC端，移动端可能有更加方便的接口，欢迎大家留意讨论反正是练手就随便抓一下pc端的包好了

主要内容

• 1.post请求登录
• 2.hmacMD5算法的简单使用

这个例子的登录非常简单没有任何加密直接post就行真的是一点加密和未知参数都没有

 

python实现，注意此处是类的一个方法不完整无法直接运行

def login(self,user_id,password):
    data = {
        'account_type': '5',
        'device_id': 'web',
        'user_id': user_id,
        'password': password
    }
    response = self.session.post(self.login_url,data=data)
    if response.status_code==200:
        temp = response.json()
        errorno = temp['errorno']
        errormsg = temp['errormsg']
        if errorno == 0:
            print('login successful!','登录成功！')
            data = temp['data']
            self.qingting_id = data['qingting_id']
            self.access_token = data['access_token']
         
        else:
            print('Login failed','登录失败')
            print(errormsg)

 

录成功后我们把access_token和qingting_id拿到，相当于一个登录后的标志如果账号是会员相当于一个会员标志

 

音频的真实地址请求了这样一个url：

https://audio.qingting.fm/audiostream/redirect/294280/11604885

其中294280是专辑id，

11604885是当前音频的id

 

其中还带了一些参数比如access_token,qingting_id(登录成功的response中有，上图没有登录所有是空的)，另外还有一些比如t是时间戳，

device_id=MOBILESITE（不变）

关键就在于sign（尝试过不加sign会返回一个签名错误）

 

可以通过全局搜索试一下是哪个js生成的这个sign我全局搜索了一下

device_id

在mian.一大堆.js 找到了生成sign的函数（需要自己分辨一下是一个device_id: "MOBILESITE"的）

搜索其他关键字应该也是可以顺利找到的

 

这里的sign是u这个变量它是由c这个变量通过一堆加密处理得到的

我们可以控制台输出一下u和c

 

所以我们就知道了sign实际是加密了请求的其他参数

一开始我误以为是单纯的MD5所以卡了好久（还进入函数内部看他具体是怎么实现的看的一头雾水）

其实代码已经告诉用的是

createHmac("md5", "fpMn12&38f_2e")

查了下Hmac发现就是一种现成的算法，还有不同的模式MD5是其中一种，需要一个秘钥

这里什么都告诉你了，用Hmac-md5秘钥是fpMn12&38f_2e

找个在线加密的网站试了下，果然和刚才控制台输出的一样

 

python的话需要import

hmac这个库

import hmac
import time
 
base_url = "https://audio.qingting.fm"
bookid = "294280"
id = "11590788"
access_token = ""
qingting_id =""
timestamp = str(round(time.time()*1000))
data = f"/audiostream/redirect/{bookid}/{id}?access_token={access_token}&device_id=MOBILESITE&qingting_id={qingting_id}&t={timestamp}"
message = data.encode('utf-8')
key = "fpMn12&38f_2e".encode('utf-8')
sign = hmac.new(key, message, digestmod='MD5').hexdigest()
whole_url = base_url+data+"&sign="+sign
print(whole_url)

得到一个音频可以做到了剩下的就是得到一堆了，其实我们得到每个音频的id就可以了

 

我请求的是这个接口

info_api = 'https://i.qingting.fm/capi/channel/{self.bookid}/programs/{self.version}?curpage={str(page)}&pagesize=30&order=asc'

version在声书主页的源代码中，只要改curpage就可以翻页了
