搞定了，需要先执行 "pip install playwright"和 "playwright install firefox"，安装必要的支持。
然后执行如下python脚本即可，数据保存在脚本所在目录下的 api_xxxx_xxxxxxxx.json文件中，我这每次执行大约不到10秒，内容如下：

from playwright.sync_api import sync_playwright
import sys
import time
import json


def record_request(request):
    # print(f'{request.url=}')
    if r'/sofr-strip-rates/?isProtected' in request.url:
        print(f'{request.url=} {request.method=}')
        response = request.response()
        try:
            response_dct = response.json()
        except Exception as err:
            print(err)
            response_dct = None
        print(f'response is: {response_dct}')
        time_str = time.strftime("%Y%m%d_%H%M%S")
        with open(f'api_{time_str}.json', 'w') as fw:
            json.dump(response_dct, fw, indent=4)


with sync_playwright() as p:
    app_url = "https://www.cmegroup.com/market-data/cme-group-benchmark-administration/term-sofr.html"
    t1 = time.time()
    print('start script now')
    browser = p.firefox.launch(headless=True)
    page = browser.new_page()
    page.on("request", record_request)
    print('goto homepage')
    page.goto(app_url)
    # page.wait_for_timeout(3000)
    print(page.url)
    print(page.title())
    t2 = time.time()
    print(f'runtime: {t2 - t1} s.')
