Find the url interface that stores the song address
First of all, we need to enter the web page of Netease Cloud. On the page, we can choose a song at will, and open the developer tool to view the corresponding interface.
In these pages, we need to find the url where the music files are stored, so we can open the global search and directly search for files related to the audio file suffix. (Of course, this may be a waste of time here)
Because when we open the media file, the suffix we see is .m4a, which is also a kind of audio file, but it is divided into a finer point. (Media files generally include audio and video)
We know the format of the returned audio, then we know what kind of return format we need to find, directly ctrl+f to search for .m4a, we can see such an interface
If you want to watch more intuitively, click preview:
At this time, we know what parameters are returned in this page, code: 200 is successfully requested, the id number of the song can also be said to be the province certificate of the song, the type url address, and some parameters that we don’t know what to do, we can all Guess what it does by the key name, (if you are still not at ease, you can directly copy the url address and open it to have a look)
After determining the returned interface, our first step has been completed.
Compare and find the parameters we need to pass decryption
In the second step, we need to try to request several different songs to find out what are the different parameters.
You can see that there are two parameters passed by post, params and ensSeckey, what is the content there, how can we pass the same parameters as the browser, that is the next problem we need to solve.
If we imagine ourselves as the person in charge of the webpage, we definitely don’t want crawlers to successfully crawl the content of our webpage, then we will set up measures, which is anti-crawling, and we want data, which is confrontation. Here I have to remind the three guidelines that crawlers need to pay attention to.
1. Always look at the gentlemen's agreement of crawling websites (Robots.txt agreement, you can also see what kind of request headers are allowed on the webpage, so our crawler experience will be a new treatment)
2. Crawling without affecting the normal operation of the server
3. Do not use crawlers for unjust enrichment, as this will violate unfair competition.
Having said so many digressions, I hope that we will construct a request header every time we crawl. Here we need to note that there is a proxy address that comes with the browser, and there is a cookie, which is a time-sensitive identity. Authentication, which sometimes contains necessary parameters, needs us to crack.
And here we can use plug-in tools for online testing. In the page, I did not pass any data to the request header, and the request can be completed by passing the post parameter as the value, so we don’t need to construct the request header here, but as a professional A well-educated reptile master, I am used to writing it up.
The name of the plugin is Talend API Tester - Free Edition
If you need to download by yourself: password: 1kbc (need to decompress and click crx file compression, edg developer mode to configure the path by yourself)
https://pan.baidu.com/s/1uFadnzIq10WDbiYNRqpRrg?pwd=1kbc
At this point, we know that we only need to pass the post data return value to the webpage, and there will be the source file address of the music, and we have completed the second step.
Analyze post form data
output module
How do we know where this data came from?
The first keyword search, we can use CTRL+shift+f to search params: and encSecKey: one of the global
The search directly brings us back to the source code here, and params: and encSecKey: still appear in pairs. It can only be said that there is a high probability that this is here. To be sure, we need further verification. This is the breakpoint debugging. See the return page Need to go through here.
At this time, we need to analyze the js code here. It can be seen that there is a function that passes in four parameters and then assigns them to bVe7X. After that, the parameters we pass are brought into bVe7X and return our post parameters. Here we need to study the internal structure of the window.asrsea function.
Click to jump to such a function body, we set a breakpoint here to continuously debug,
There are five functions here. Function a is to generate a random string of 16 characters. Function b passes in two values to encrypt the module. This is AES symmetric encryption. The following offset and module CBC are common encryption methods. We can express these three functions and python code through continuous attempts. We know how the post data in the interface is output, and then we need to know what data we need to input.
Input data
Through constant attempts, I learned that three of the four parameters passed in the window.asrsea function are fixed values, and the other one is to determine the unique identifier of the song.
Then there is another unique identifier to determine the song.
It can be seen that the passed parameters can set the sound quality and ids number of the song. . .
At this point our analysis is over. The next section is my code stage, which will be continued tomorrow.
This is the first time I write a python crawler actual combat, the writing is bumpy, and I feel like I have more energy than energy, forgive me! ! !
