I am also not sure if I should've used a yield instead of a return somewhere in there. Vierailijoiden datan analysointi osoittaa, että Mozilla Firefox Bookmarks Backup-tiedostotyyppi löytyy tyypillisesti Windows 10-käyttöjärjestelmiltä. It appears to work and it follows all of the links I made from the JSON page. Mikä on tiedostotunniste JSON Microsoft WordPad on ensisijainen ohjelmisto Mozilla Firefox Bookmarks Backup-tiedostyypeille, ja sen alkuperäisesti kehittäjä on Microsoft Corporation. However, I am sure this is a hacky and inelegant way to accomplish this. I now need to generate the URLs, in the form of a Request, from the JSON page's reponse: def make_json_links(self, response):ĭata = json.loads(response.body_as_unicode())Īnd now it seems to work. Only the JSON page should be processed here.īecause of this I needed to add my special JSON url with my html urls: start_urls = If 'externaljson.php' in str(response.url): I added the following to my Spider: # A request object is required.Īnd: def parse_start_url(self, response): I wanted to parse a JSON Response and then send a Request to be further processed by scrapy. ![]() And maybe my original post was not clear. It seems I have found a way to make it work. Item = section-header']/h1/span/text()").extract() Rule(LinkExtractor(allow=('showthread\.php\?t=\d ',), I hope someone can advise!įrom import CrawlSpider, Ruleįrom import LinkExtractorĪllowed_domains = Very confused as to how to implement this in scrapy. Ideally, I would like it to work with the spider that I already have, not sure if that is possible though. My question is, where do I put this code? I am very confused as to how to incorporate this into scrapy? Do I need to create another spider? It seems I will need to create my own request object to send to parse_link in the spider? This function will return proper links to the HTML pages (links to forum threads) that I want to scrape. # URL is formed simply by concatenating the canonical link with a thread-id:įor post in tsr_data: # (there are no URLs at all in the JSON data, they must be formed manually): # Iterate over the json data and form the URLs Tsr_data = requests.get(url, headers= user_agent).json() Past = () - datetime.timedelta(minutes=15) ![]() # Form the end of the URL, it is based on the time (unixtime): Here is what I want to do (Here it is done manually, without scrapy): import requests, json However, I want to add an additional feature. In layman's terms, I wanted the script to perform exactly how it usually does, with the only exception being that I wanted to be able hit a modifier key ⌘ that would pass my current query to another script, in circumstances where I wasn't able to find what I was looking for.I have a spider (click to see the source) that works perfectly for regular html page scraping. Is this update as easy as adding a line or two of code to the script above? Or is it something that is going to require a more fundamental rethinking of everything? And, relatedly, since I'm not even sure where to start researching this sort of thing, do you have any suggestions for my code above, or other python-related workflows that you could point me to, where I might be able to learn how to accomplish this? Surprisingly, I only have a small handful of python workflows installed on my machine, and none appear to operate in this manner (at least from what my neophyte eyes can tell, anyways). So, if I'd like to pass my query, how do I get my script to filter the results as the user inputs their query (similar to Alfred)? In layman's terms, how do I get the script filter to remove items from Alfred's visible output as the user inputs their query (based on the "match" criteria)? As you correctly pointed out, my script just dumps all of the results into Alfred - meaning that they all just kind of sit there. ![]() This all makes perfect sense (now, anyways ?♂️️)! Thanks again for all of your it! Thanks for your patience, and excellent explanation above. Is there any easy way to remove items whose titles can be found in another list?Īdmittedly, I normally do these sorts of things in AppleScript - which is pretty easy to do in this case - except that I’ve been trying to learn a little python, given all of the limitations with AppleScript (which rightly reminded me of on numerous occasions, so hopefully this will make them proud ?).įor example, let’s say that I have the following list: At the moment, the script filter works great except that it includes a few items I'd prefer not to see in Alfred's output. I have a very basic python question that I was hoping to get a little help with that involves filtering out list items in a script filter.
