Analyze the js code execution from the website, and then extract it. This extraction process is more complicated than before, and finally use execJS to execute the JS code
Step 1: Familiarize yourself with the requirements
Target website: unicom_trip.133.cn/city/?syste…
The part of the data required
Step 2: Find the asynchronous loading interface and analyze the interface data
We see the data displayed on the page, and we go to XHR for a request
I think that’s where THE LXA comes from, right? Date =20220303&type=arr data obtained in the request, we first analyze whether there are encryption parameters, found that there is no, can directly request to get the data
When we look at the data, we see that the data part is a string
Here’s a trick to note:

We can get the conclusion is that the data is encrypted, the front end from the back end to obtain the data, decrypted through JS, the data extracted and put on the page, analyze JS
Step 3: We need to find the decryption JS part
3.1 the search
We parsed the base64 characters so that we had two choices. We could use a trick, search json.parse or search directly by key MAC
Parse too many searches through json.parse
Let’s try changing the MAC key
3.2 analysis of js
Here’s a trick: we search for multiple matches, we intuitively filter them, and then we hit breakpoints on the ones we can’t distinguish, refresh the page, see if they go through that interface, see if they’re the same as our data, and we can quickly select the variable we’re looking for
We make a break point at the suspicious place
3.3 Set breakpoints and refresh the page for debugging
The detailed debugging process was shown in the previous tutorial, and this section is used directly with lookup
The refresh runs, and at the first breakpoint, we find a dictionary corresponding to the city code and the city name, which is useful for our subsequent data retrieval
In the console we can get cityList, there are too many data only for partial data display
{"999": {"city_code":"999"."city_name":"Indistinguishable"},"V0152900": {"city_code":"V0152900"."city_name":"The Arab league"},"V0152200": {"city_code":"V0152200"."city_name":"Hinggan Unita"},"V0150400": {"city_code":"V0150400"."city_name":"Chifeng"},"V0150100": {"city_code":"V0150100"."city_name":"Hohhot"},"V0152302": {"city_code":"V0152302"."city_name":"Hulun Buir"},"V0152700": {"city_code":"V0152700"."city_name":ordos},"V0152500": {"city_code":"V0152500"."city_name":Xilin Gol},"V0152800": {"city_code":"V0152800"."city_name":bayannur},"V0152600": {"city_code":"V0152600"."city_name":"Ulanchabu"},... 'Remaining data omitted'}Copy the codeWe skip the first breakpoint and go to the second breakpoint, and we find that this is where we are looking for the JS data parsing part
After testing on the console, we can see that the data is parsed through this section, so the next step is to deduct JS
** Rewrite JS **: Simple integration of JS code into the desired format
function dataDecode(data){
var base = new Base64();
var d = JSON.parse(base.decode(data));
var key = 'UVJgCE+OFIff3hK5BT5sPBbGZzjR6FwntjSCwOA9tUQ=';
var key1 = CryptoJS.enc.Base64.parse(key);
var iv1 = CryptoJS.enc.Base64.parse(d.iv);
var decrypted=CryptoJS.AES.decrypt(d.value,key1,{
iv : iv1,
mode : CryptoJS.mode.CBC,
padding : CryptoJS.pad.Pkcs7
});
var d = decrypted.toString(CryptoJS.enc.Utf8);
return JSON.parse(d);
}
Copy the code3.4 Tracing relevant JS
Principle: What is missing
We can create a new JS file, put the dataDecode function in it, and run the code
# encrypt_data is available from the request
import execjs
with open("test.js"."r",encoding="utf-8") as f:
str1 = f.read()
ctx = execjs.compile(str1)
a = ctx.call('dataDecode', encrypt_data)
Copy the codeWe get the error Base64 does not exist, and look for the H method, which was detailed in the last tutorial
Find Base64 in the web page and append it to our test.js

Searching in a web page is quite tedious. First of all, CryptoJS is an object, so you can’t directly jump in and find the relevant file, and you don’t know where to stop
First problem, can’t jump in –> Solution: Parse into this file using the following method
Second problem, do not know when to stop –> Solution: based on experience (more abstract)
Let’s analyze: this part is actually a CryptoJS object wrapped in a factory way
The CryptoJS object is returned in the last section
So after analysis, all the code in the middle is CryptoJS object code (code is too long to put in the note, only put in the start and end position).
Let’s put it in a JS file
Step 4: Python retrieves the data and decrypts it with JS
Then we can decrypt the encrypted data we have obtained by executing js files
