scrapy-jsonrpc

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

Example client

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.

Settings

These are the settings that control the web service behaviour:

JSONRPC_ENABLED

Default: True

A boolean which specifies if the web service will be enabled (provided its extension is also enabled).

JSONRPC_LOGFILE

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.

JSONRPC_PORT

Default: [6080, 7030]

The port range to use for the web service. If set to None or 0, a dynamically assigned port is used.

JSONRPC_HOST

Default: '127.0.0.1'

The interface the web service should listen on.
