This is the installation documentation for installing the LegiScan API Client on Linux. This guide is written for installation from source on a Debian platform and any Linux variant should work with little modifications. There is nothing intrinsically Linux specific to the code, so Windows based servers with access to PHP should work with as well, though not officially tested with MSSQL.
API Client source documentation is available at: LegiScan API Client Documentation
Additional documentation and data dictionary is available at: LegiScan API Manual
For information about support options and upgrading to Push API please email us at info@legiscan.com, or call 800-618-2750 x401
The following files are included in the LegiScan API archive:
In this example we will install the package under /opt, this could
also be your root web server folder such as /var/www.
Unpack the archive that you downloaded from legiscan.com.
This will create a new directory legiscan that has all the files necessary to
interface with the LegiScan API.
cd /opt
wget https://api.legiscan.com/dl/legiscan-current.tar.gz
tar zxvf legiscan-current.tar.gz
cd legiscan
You will need to have a valid API key, if you don't already have one you can get one for free at LegiScan API Registration
When upgrading from a previous version unpack the archive over the existing
installation, verify if there are any config.php updates that need to be applied,
then run the upgrade.php script to make any schema and data modifications.
php upgrade.php
Create the legiscan_api database, add a user legiscan_api with password
<your password>, grant rights on the database to the new user and reload
privleges.
mysql -u root -p
CREATE DATABASE legiscan_api DEFAULT CHARACTER SET utf8;
GRANT USAGE ON *.* TO 'legiscan_api'@'localhost' IDENTIFIED BY '<your password>';
GRANT CREATE, ALTER, SELECT, INSERT, UPDATE, DELETE ON `legiscan_api`.* TO 'legiscan_api'@'localhost';
FLUSH PRIVILEGES;
exit
Next load the schema and static lookup tables.
mysql -D legiscan_api -u root -p < schema-mysql.sql
Create the legiscan_api user with password <your password> since in
PostgreSQL the assumption is a database will exist with the same name as
the role being used to login.
sudo -u postgres createuser -S -D -R -P legiscan_api
Enter password for new role: <your password>
Enter it again: <your password>
Next create the actual database legiscan_api owned by legiscan_api.
sudo -u postgres createdb -E UTF8 -O legiscan_api legiscan_api
Finally load the schema and static lookup tables.
sudo -u postgres psql -U legiscan_api -f schema-pgsql.sql
See: Entity Relationship Diagram for a schema overview and table relations.
Copy the sample configuration file to its proper location.
cp config.dist.php config.php
Using your favorite text editor, open the config.php file and follow the
instructions included in the file for setting up configuration options.
vim config.php
Of particular note enter your api_key and change dsn, db_pass to the
value set in the above step.
If setting up for pull, update_type and the states list and/or searches
lists should be populated. You may also want to tune the global relevance
cutoff for searches.
Local document storage is disabled by default, change want_bill_text,
want_amendment, want_supplement if needed.
In general the LegiScan Client expects to be ran under a single non-privledged
account, often www-data or similar account when running from a web server, or
perhaps a custom user/group. Whatever the case, mixing users later on will result
in permission conflicts within cache.
There are several directories specified in config.php that need to be writable
by the user running the scripts. By default these are located within the legiscan
directory, if you select alternate locations please ensure proper permissions
and access.
chown -R www-data cache/api cache/doc log signal
NOTE: Be consistent when running from command line e.g., sudo -u www-data php legiscan-cli.php.
NOTE: If middleware_signal is not used or is table based, the signal directory can be ignored.
Starting here is STRONGLY encouraged as a few hundred files are the equivalent of approximately 2 million individual API calls.
Using the getDataset API hooks, a manually downloaded copy of a weekly Public Dataset, or a custom subscriber onboarding snapshot, this script will extract the contents of the archives and import/update data as needed.
When using getDataset, the script can operate in two modes, --scan and --bulk,
both of which import new and updated datasets.
The --scan mode acts like a interactive search / browser with command line filters
to import eligible datasets. While in --bulk mode, the states[] and years[]
variables in config.php will be used to select which datasets will be
synchronized. The latter of which is most appropriate for scheduling automated
updates.
Show the command help
php legiscan-bulk.php --help
Use config.php settings to import datasets and answer yes to any prompts.
php legiscan-bulk.php --bulk --import --yes
Show a listing of all available datasets in California and their status
php legiscan-bulk.php --scan --state CA
Import all new/changed datasets in 2020 with verbose output
php legiscan-bulk.php --scan --year 2020 --import --verbose
Import all new/changed 2016 special sessions in North Carolina
php legiscan-bulk.php --scan --state NC --special --year 2016 --import
Process example.zip but do not import, only show what would have been done
php legiscan-bulk.php --file example.zip --dry-run --debug
NOTE: This will not pull local copies of documents unless they are included in the archive, though appropriate stub records will be created.
The legiscand.php script provides a daemon process that can use four different
methods of keeping a local database synchronized via LegiScan Pull API.
This mode will use the ls_monitor table to keep a specific bill_id list
updated. This list can be managed with legiscan-cli.php, though determining
the bill_id is an exercise for the reader and would require additional
scripting, though a likely source would be through the search engine.
php legiscan-cli.php --monitor 823882
php legiscan-cli.php --unmonitor 823882
This mode will synchronize the entire master list from one or more states. To set
the state list edit config.php and add each state to the states[] setting.
For example to track all legislation in California and US Congress:
states[] = CA
states[] = US
NOTE: We HIGHLY recommend pre-loading the current state dataset with
legiscan-bulk.php prior to the first run to minimize the on-boarding queries.
This mode will synchronize the results of searches ran against the national
database. To specify the searches edit the config.php and add each search
to the searches[] setting.
The searches will also be filtered by the global relevance cutoff setting,
which can be overridden on a per search basis by prepending a different score
and the pipe | character. In addition a state abbreviations can also be
prefixed to override either national or state search. When used with a relevance
override the state should appear first separated by a comma ,.
Also notice that the entire search string should be quoted, and any internal
quotes should be escaped as \".
searches[] = "gender AND bathroom"
searches[] = "\"national popular vote\""
searches[] = "42|hemp OR cannabis OR marijuana"
searches[] = "NY|charter ADJ schools"
searches[] = "CA,60|vaccination AND status:passed"
This mode combines both of the other methods such that the searches[] are only
ran against the states[] list, unless a search specific state is used.
The legiscan-push.php script serves as the endpoint listener for LegiScan
Push API services. This will receive payloads from the LegiScan Push server
and process them into the provided database. The LegiScan API Client should
be installed in a location that is accessible by your web server and externally
by LegiScan servers.
For additional authentication you may also set api_auth_key which can be found in
the LegiScan API control panel at legiscan.com.
This will validate against the HTTP Authorization header sent with incoming payloads
and reject those with invalid tokens.
And if your API key is set to receive cooked application/x-www-form-urlencoded
payloads, be sure to change the push_form_var setting to the form variable
name specified in the API control panel.
NOTE: To utilize this script you will need a Push API subscription.
The CLI interface allow for importing specific objects from the command line along with manipulating some internal controls. This could be used for testing purposes or for automation with other custom scripting.
Show the command help
php legiscan-cli.php --help
Import the current GAITS monitoring list associated with the API key and sync
with the local ls_monitor list
php legiscan-cli.php --monitorlist --import all --sync
Get the master list for the most recent session in California, but do not actually import and dump the response payload
php legiscan-cli.php --dry-run --debug --masterlist CA
Request a specific bill_id be imported locally
php legiscan-cli.php --bill 823201
Run a national search and import new bills with a relevance score of 75% or higher
php legiscan-cli.php --search "citizens ADJ united" --state ALL --import new --score 75
Add a bill_id to the monitor list with support stance and synchronize with GAITS
php legiscan-cli.php --monitor 843038,908829,817390 --stance support --sync
Add a bill_id to the ignore list
php legiscan-cli.php --ignore 898381
Clean the API cache of stale entries
php legiscan-cli.php --clean --verbose
The web interface is primarily for demonstration purposes to generate single
API requests to examine payload structure. The LegiScan API client and legiscan-ui.php
should be accessible by your web server. Then point your brower to the URL of
interface script (e.g., http://example.com/legiscan/legiscan-ui.php).
Enter your API key in the space provided, select the type of payload request
you would like and enter the appropriate ID, then click Run Test.
The system will then output the decoded payload response.
The LegiScan API Client supports signaling a third party application of bill
and related data changes so that additional processing can be done. The use case
for this would be when the legiscan_api database is used as staging for another
custom production system already in place.
This is controlled by the middleware_signal setting and can be either table
or directory based.
When a bill first appears or later updated, or a new text, amendment, supplement,
roll call or person record is created a record will be made in the ls_signal
table within the legiscan_api database.
This record will contain the object_type, its internal object_id and a
processed flag.
The third party application should scan the table for processed = 0, take
any necessary actions, then update the record with processed = 1.
When a bill first appears or later updated, or a new text, amendment, supplement,
roll call or person record is created a file will be created in the signal
directory.
This file will be named in the form of object_type.object_id and will contain
a JSON object containing the same field along with the updated time stamp.
The third party application should scan the directory for files, take any
necessary actions, then delete the file from the signal directory.
To install the LegiScan Pull Daemon so that it runs on startup and can be
controlled by service. This file presumes the install location is /opt/legiscan,
if this is not the case edit the legiscan.service file and change LEGISCAN_PATH.
cp legiscan.service /etc/init.d/legiscan
chmod +x /etc/init.d/legiscan
update-rc.d legiscan defaults
service legiscan start
For scheduled bulk updates, the following will add a weekly cron job to pull dataset updates as needed.
tee /etc/cron.weekly/legiscan-bulk <<EOF
#!/bin/sh
php -q /opt/legiscan/legiscan-bulk.php --bulk --import --yes
EOF
chmod +x /etc/cron.weekly/legiscan-bulk
If running via the Pull interface, the API cache directory will grow over time. This will create an hourly cron job to clean stale entries.
tee /etc/cron.hourly/legiscan-clean <<EOF
#!/bin/sh
php -q /opt/legiscan/legiscan-cli.php --clean
EOF
chmod +x /etc/cron.hourly/legiscan-clean
