QUESTION
I'm new to Scrapy-splash
and I'm trying to scrape a lazy datatable
which is a table with AJAX pagination.
So I need to load the website, wait until JS
is executed, get html of the table and then click on the "Next" button on pagination.
My approach works but I'm afraid I'm requesting the website two times.
First time when I yield the SplashRequest
and then when lua_script
is executed.
Is it true? If yes, how to make it perform request just once?
...ANSWER
Answered 2019-Jan-24 at 13:50Lua script is very literal - if you have 1 splash:go
then one request is made by 1 splash worker.
Your crawler is fine here.
To pointlessly nit pick though: your spider connects to a worker via http so in theory two requests are being made: 1st to splash service and 2nd to target by splash worker.
