如何正确地将POST请求发送到Pyppeteer中的网站

import asyncio
from pyppeteer import launch

async def send_post_request(url, data):
    browser = await launch()
    page = await browser.newPage()
    await page.goto(url)
    await page.evaluate('''() =>{ Object.defineProperties(navigator,{ webdriver:{ get: () => false } }) }''')
    await page.evaluate('''() =>{ window.navigator.chrome = { runtime: {},  }; }''')
    await page.evaluate('''() =>{ Object.defineProperty(navigator, 'languages', { get: () => ['en-US', 'en'] }); }''')
    await page.evaluate('''() =>{ Object.defineProperty(navigator, 'plugins', { get: () => [1, 2, 3, 4, 5,6], }); }''')
    await page.setRequestInterception(True)
    page.on('request', (request) => {
        if request.method == 'POST':
            request.continue({'postData': data})
        else:
            request.continue()
    })
    await page.goto(url)
    await browser.close()

url = 'https://example.com'
data = {'key1': 'value1', 'key2': 'value2'}
loop = asyncio.get_event_loop()
loop.run_until_complete(send_post_request(url, data))
