Scrapy 2.2 Documentationstart_requests(): must return an iterable of Requests (you can return a list of requests or write a generator function) which the Spider will begin to crawl from. Subsequent requests will be generated successively from method of the Spider. Upon receiving a response for each one, it instantiates Response objects and calls the callback method associated with the request (in this case, the parse method) passing the response to make the code shorter; it also works for Request. The parse_author callback defines a helper function to extract and cleanup the data from a CSS query and yields the Python dict with the author data0 码力 | 348 页 | 1.35 MB | 1 年前3
