Answer 1

For the windows users, who use Docker Toolbox:

1. Change the single inverted comma with double inverted comma for preventing the invalid hostname:http error.

2. change the localhost to the docker ip address which is below the whale logo. for me it was 192.168.99.100.

Finally i got this:

Answer 2

You can run scrapy shell without arguments inside a configured Scrapy project, then create req = scrapy_splash.SplashRequest(url, ...) and call fetch(req).

Answer 3

just wrap the url you want to shell to in splash http api.

So you would want something like:

scrapy shell 'http://localhost:8050/render.html?url=http://domain.com/page-with-javascript.html&timeout=10&wait=0.5'

where localhost:port is where your splash service is running
url is url you want to crawl and dont forget to urlquote it!
render.html is one of the possible http api endpoints, returns redered html page in this case
timeout time in seconds for timeout
wait time in seconds to wait for javascript to execute before reading/saving the html.
