scrapy-jsonrpc is an extension to control a running Scrapy web crawler via JSON-RPC. The service provides access to the main Crawler object via the JSON-RPC 2.0 protocol.
It's enabled by the JSONRPC_ENABLED setting. The web server will listen in the port specified in JSONRPC_PORT, and will log to the file specified in JSONRPC_LOGFILE.
The endpoint for accessing the crawler object is:
http://localhost:6080/crawler
There is a command line tool provided for illustration purposes on how to build
a client. You can find it in example-client.py. It supports a few basic
commands such as listing the running spiders, etc.
These are the settings that control the web service behaviour:
Default: True
A boolean which specifies if the web service will be enabled (provided its extension is also enabled).
Default: None
A file to use for logging HTTP requests made to the web service. If unset web the log is sent to standard scrapy log.
Default: [6080, 7030]
The port range to use for the web service. If set to None or 0, a
dynamically assigned port is used.
Default: '127.0.0.1'
The interface the web service should listen on.
