How to intercept AJAX JSON response in Pyppeteer

This example shows you how to intercept and print the content of a JSON response requested via any AJAX request on a web page by using Pyppeteer:

import asyncio
import json
from pyppeteer import launch

async def intercept_network_response(response):
    # In this example, we care only about responses returning JSONs
    if "application/json" in response.headers.get("content-type", ""):
        # Print some info about the responses
        print("URL:", response.url)
        print("Method:", response.request.method)
        print("Response headers:", response.headers)
        print("Request Headers:", response.request.headers)
        print("Response status:", response.status)
        # Print the content of the response
        try:
            # await response.json() returns the response as Python object
            print("Content: ", await response.json())
        except json.decoder.JSONDecodeError:
            # NOTE: Use await response.text() if you want to get raw response text
            print("Failed to decode JSON from", await response.text())

async def main():
    browser = await launch()
    page = await browser.newPage()
    
    page.on('response', intercept_network_response)
            
    await page.goto('https://instagram.com')
    await browser.close()

asyncio.get_event_loop().run_until_complete(main())
