Scrape Tenda Router Data with Python Requests and Serve It via a Flask API

1. Analyze the router page

The router is a Tenda device whose management IP is 192.168.0.1. By opening the router's web UI, pressing F12, and inspecting the Network tab, you can see that the router polls data using GET requests such as:

http://192.168.0.1/goform/getStatus?random=0.46529553086082265&modules=internetStatus,deviceStatistics,systemInfo,wanAdvCfg,wifiRelay,wifiBasicCfg,sysTime

The random parameter is irrelevant and can be removed, leaving the core URL pattern: http://192.168.0.1/goform/getStatus?modules=XXX By examining the JavaScript files loaded by the router UI, you can collect all possible values for the modules parameter. After deduplication, 33 module names are identified, e.g., wifiBasicCfg, wifiAdvCfg, wifiPower, loginAuth, wanAdvCfg, systemInfo, internetStatus, etc.

2. Send requests (code)

import requests
import json
module = [
    "wifiBasicCfg",
    "wifiAdvCfg",
    "wifiPower",
    "wifiWPS",
    "wifiGuest",
    "wifiBeamforming",
    "loginAuth",
    "wanAdvCfg",
    "lanCfg",
    "softWare",
    "wifiRelay",
    "sysTime",
    "remoteWeb",
    "isWifiClients",
    "systemInfo",
    "hasNewSoftVersion",
    "internetStatus",
    "deviceStatistics",
    "parentCtrlList",
    "parentAccessCtrl",
    "wanBasicCfg",
    "localhost",
    "onlineList",
    "macFilter",
    "guestList",
    "staticIPList",
    "IPTV",
    "portList",
    "ddns",
    "dmz",
    "upnp",
    "ping"
]

class Wifi:
    """Fetch Wi‑Fi related data from the router"""
    def __init__(self, IP='192.168.0.1'):
        self.IP = IP
        self.data = self.req()

    def req(self):
        """Send request and return JSON data"""
        session = requests.session()
        module_args = ",".join(module)
        url = f'http://{self.IP}/goform/getStatus?&modules={module_args}'
        try:
            resp = session.get(url).json()
            self.status = True
        except Exception:
            self.status = False
            resp = None
        return resp

    def get(self, config_name):
        if self.status:
            if config_name == "all":
                data = self.data
            else:
                try:
                    data = self.data[config_name]
                except Exception:
                    data = f"no_{config_name}_data"
        else:
            data = f"no_{config_name}_data"
        return data

3. Build a simple Flask API

from flask import Flask, jsonify
from wifi import Wifi

app = Flask(__name__)

w = Wifi()

@app.route('/api/<config_name>', methods=['POST', 'GET'])
def get(config_name):
    try:
        return jsonify(w.get(config_name))
    except Exception:
        return "404"

if __name__ == '__main__':
    app.run(debug=True)

The script can be run as app.py. When accessed via a browser, e.g., http://127.0.0.1:5000/api/internetStatus, it returns the requested router data in JSON format.

An alternative functional implementation is also provided, showing how to achieve the same result without a class.

Overall, the article demonstrates a practical method for reverse‑engineering a router's internal API, extracting all configuration modules, and exposing them through a lightweight Flask service.
