[py.warnings] WARNING: E:\Python\Lib\site-packages\scrapy_splash\dupefilter.py:20: ScrapyDeprecationWarning: Call to deprecated function scrapy.utils.request.request_fingerprint().
If you are using this function in a Scrapy component, and you are OK with users of your component changing the fingerprinting algorithm through settings, use crawler.request_fingerprinter.fingerprint() instead in your Scrapy component (you can get the crawler object from the 'from_crawler' class method).
Otherwise, consider using the scrapy.utils.request.fingerprint() function instead.
Either way, the resulting fingerprints will be returned as bytes, not as a string, and they will also be different from those generated by 'request_fingerprint()
'. Before you switch, make sure that you understand the consequences of this (e.g. cache invalidation) and are OK with them; otherwise, consider implementing your own function which returns the same fingerprints as the deprecated 'request_fingerprint()' function.
fp = request_fingerprint(request, include_headers=include_headers)
只改动了setting和爬虫文件,有大佬知道什么原因吗
