It is a bit of complicated to get the data from the direct url address
There are 8 pages ,you have to extract data in one webpage and turn to other page and extract it over and over.

Searched a project which can get the data from an api,i show part of the codes here:

url = ""
params = {
    "pn": "1",
    "pz": "5000",
    "po": "1",
    "np": "1",
    "ut": "bd1d9ddb04089700cf9c27f6f7426281",
    "fltt": "2",
    "invt": "2",
    "fid": "f243",
    "fs": "b:MK0354",
    "fields": "f1,f152,f2,f3,f12,f13,f14,f227,f228,f229,f230,f231,f232,f233,f234,f235,f236,f237,f238,f239,f240,f241,f242,f26,f243",
    "_": "1590386857527",
r = requests.get(url, params=params)
text_data = r.text

The method above is so simple,but i want to know how can get the data api from , analyse data stream to get ,with chrome’s inspect or other tools and method?Please show the way to get it.
