QUESTION
I'm trying to use pyinstaller to convert my python file into an executable, but I keep getting this error.
...ANSWER
Answered 2021-Jun-03 at 01:43There is a workaround on pyppeteer issue #213: editing the __init__.py as nonewind suggests.
In pyppeteer/__init__.py, simply add the line
QUESTION
I'm using "python requests_html" because I want to get the rendered html source code. In addition, I want to do that via socks5h(Tor) proxy.
So, I tried to write the following code. However, once render() function was called, raw ip address is displayed. This seems that render() function doesn't use proxy settings.
Actually, I tried to connect to tor bbc news (onion domain) using the following code, it failed, because that's not tor network.
Is there any good idea to render using socks5h proxy?
...ANSWER
Answered 2021-May-31 at 01:45Sorry for the self answer. requests_html uses pyppetter internally, and this proxy issue depends on pyppeteer. Current requests_html seems that it doesn't pass proxy information, so pyppeteer doesn't use proxy. According to the following github pages, it seems that this issue would be solved in the future.

QUESTION
I want my script to
Open say 3 tabs
Asynchronously fetch a url(same for each tab)
Save the response
Sleep for 4 seconds
Parse through the response with regex(I tried BeautifulSoup but its too slow) and return a token
Loop through several times within the 3 tabs
My problem is with 2. I have an example script but it synchronously fetches the url. I would like to make it asynchronous.
...ANSWER
Answered 2021-Apr-03 at 19:22This will open each URL in a separate tab:

A beginner in JS/Html, I'm trying to fetch the content of a page after clicking on a link, through Pyppeteer0.2.5 (Python3.6.9/Chromium 87.0.4280.66) using the following code:

QUESTION
I use Pyppeteer library because there is a Chrome Dev Tools protocol and I can receive webSocketFrameReceived after sending a request in UI test. I was able to print the socket response to the terminal, but that's not what I want. I need, depending on the status of one of the response parameters (marked on the screenshot https://www.screencast.com/t/4wKSIcPjL9T), to continue my test differently. How can I do this? How to deal with socket response? save answer to Python dictionary? Any idea

QUESTION
I'm currently designing a spider to crawl a specific website. I can do it synchronous but I'm trying to get my head around asyncio to make it as efficient as possible. I've tried a lot of different approaches, with yield, chained functions and queues but I can't make it work.
I'm most interested in the design part and logic to solve the problem. Not necessary runnable code, rather highlight the most important aspects of assyncio. I can't post any code, because my attempts are not worth sharing.
The mission:
The exemple.com (I know, it should be example.com) got the following design:
In synchronous manner the logic would be like this:

Answered 2020-Sep-12 at 11:54Let's restructure the sync code so that each piece that can access the network is in a separate function. The functionality is unchanged, but it will make things easier later:
