我正在尝试使用Pypetteer从这个网站上抓取数据，如果没有这个选项，这个网站就会知道我在抓取数据

因此，我的第一个问题是：

使用Pypetteer进行抓取时，网站不会注意到我正在进行抓取，这是正确的吗？ 在右上角输入时，会出现一个下拉列表，其中包含以下项目：概述、损益表、…、关键比率

我想使用pyppeteer从下拉列表中选择关键比率，从中提取每股项目的数据，并从中提取账面价值行

在我在那个网站上的预览问题的最后一条评论中，我被告知这个下拉列表只会触发显示相同数据的不同方式

所以我的第二个和第三个问题可能是相同的：

我是否应该以某种方式模拟使用Pypetteer选择的关键比率

如何使用Pypetteer从密钥比率触发器中提取数据，而不让网站知道有人正在删除它

我用这些问题编写了一个代码，但是我的代码只从第一个概述页面中提取数据

这是我基于代码的问题

我也试着从中了解如何使用底部，但不是使用Pypetteer来制作Python，而是使用木偶演员

这是我使用的代码：

import pyppeteer
import asyncio

async def main():
# launches a chromium browser, can use chrome instead of chromium as well.
browser = await pyppeteer.launch(headless=False)
# creates a blank page
page = await browser.newPage()
# follows to the requested page and runs the dynamic code on the site.
await page.goto("https://api.quickfs.net/stocks/BABA:US/ovr/Annual/")
# provides the html content of the page
cont = await page.content()
return cont

# prints the html code
print(asyncio.get_event_loop().run_until_complete(main()))
ovr=(asyncio.get_event_loop().run_until_complete(main()))
提前感谢

问题1：使用pyppeteer进行刮伤不会被网站注意到是不是正确？ 答案很简单：是的。这个网站正在使用javascript，所以你需要一个类似Pypetteer的东西来呈现网页。同样，使用Pypetteer也会像普通用户一样进行模拟。所以被发现的机会就少了

您应该能够阅读，以便更好地了解如何真正做到这一点

问题3：如何使用Pypetteer从关键比率触发器中提取数据，而不让网站知道有人正在删除它？ 简短回答：您可以使用类似于问题2的答案的选择器抓取表格。然后解析出表

技术回答：更好地了解网站的工作方式。你可以对网站进行反向工程，了解其工作原理。使用ChromeDevTools之类的工具，您可以看到它调用了API。API以易于解析的JSON格式返回您需要的所有数据。使用API是很简单的。只要换一下股票行情

为阿里巴巴获取数据 https://api.quickfs.net/stocks/BABA:US/ovr/Annual/ 获取特斯拉的数据 https://api.quickfs.net/stocks/TSLA:US/ovr/Annual/ 为苹果获取数据 https://api.quickfs.net/stocks/AAPL:US/ovr/Annual/ 然后，您只需通过请求调用Python中的API即可：

导入请求 resp=请求。gethttps://api.quickfs.net/stocks/AAPL:US/ovr/Annual/ data=resp.json
谢谢你的详细回答！如果你同意，我想问一下你对问题2的回答。我试图运行您编写的代码，但出现错误-pyppeteer.errors.ElementHandleError:error:failed to find element matching selector:以下是答案代码中括号中的内容您如何知道应该在选择器中编写什么？我读了文档，但不知道其中应该包含什么。我的第二个问题是关于您编写的问题3的代码。它似乎不是在使用pyppeteer，而是在使用requests包——有没有办法对pyppeteer进行同样的操作？
