Windows: crawl freezes when multiple schemas are set in DOWNLOAD_HANDLERS #290
Description
If I have said anything impolite, please forgive me, as I have used a translator. My basic situation is the same as this issue Spiders hangs. I locate the problem to this setting item.
"DOWNLOAD_HANDLERS": { "https": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler", "http": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler", },Code
When I comment out DOWNLOAD_HANDLERS, the spider runs normally. Here is my code, you can directly run it and try.
from pathlib import Path from scrapy.crawler import CrawlerProcess import scrapy class QuotesSpider(scrapy.Spider): name = "quotes" def start_requests(self): urls = [ "https://quotes.toscrape.com/page/1/", "https://quotes.toscrape.com/page/2/", ] for url in urls: yield scrapy.Request(url=url, callback=self.parse, meta={"playwright": True},) def parse(self, response): page = response.url.split("/")[-2] filename = f"quotes-{page}.html" Path(filename).write_bytes(response.body) self.log(f"Saved file {filename}") if __name__=="__main__": process = CrawlerProcess( settings={ "TWISTED_REACTOR": "twisted.internet.asyncioreactor.AsyncioSelectorReactor", "DOWNLOAD_HANDLERS": { "https": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler", "http": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler", }, "CONCURRENT_REQUESTS": 32, } ) process.crawl(QuotesSpider) process.start()Result

Is it possible that it is related to the computer system? I currently do not have a computer with a Linux system and cannot verify this. Besides, I am in China, could it be related to the IP address? However, I checked the ScrapyPlaywrightDownloadHandler class and did not see any bugs. Thank you for your help.
