This alpha stage package provides a very simple way to access api.govinfo.gov

See console demo

Install

You can install this package via composer.

composer require cnizzardini/gov-info

Usage

Retrieve an index of all collections available

use GovInfo\Api;
use GovInfo\Collection;

$api = new Api(
    new \GuzzleHttp\Client(), 
    'DEMO_KEY'
);
$collection = new Collection($api);
$result = $collection->index();

After running this code $result will contain a non-truncated version of collections:

Array
(
    [collections] => Array
        [
            [0] => Array
                [
                    [collectionCode] => USCOURTS
                    [collectionName] => United States Courts Opinions
                    [packageCount] => 1134933
                    [granuleCount] => 2525240
                ]
        ...
)

Retrieve all packages in a collection

use GovInfo\Api;
use GovInfo\Collection;
use GovInfo\Requestor\CollectionAbstractRequestor;

$api = new Api(
    new \GuzzleHttp\Client(), 
    'DEMO_KEY'
);
$collection = new Collection($api);
$requestor = new CollectionAbstractRequestor();

$requestor
    ->setStrCollectionCode('BILLS')
    ->setObjStartDate(new DateTime('2019-01-01'));

$result = $collection->item($requestor);

After running this code $result will contain a non-truncated version of packages:

Array
(
    [count] => 202767
    [message] => 
    [nextPage] => https://api.govinfo.gov/collections/BILLS/2018-01-01T00:00:00Z/?offset=100&pageSize=100
    [previousPage] => 
    [packages] => Array
        [
            [0] => Array
                [
                    [packageId] => BILLS-115hr2740rfs
                    [lastModified] => 2018-11-16T00:33:17Z
                    [packageLink] => https://api.govinfo.gov/packages/BILLS-115hr2740rfs/summary
                    [docClass] => hr
                    [title] => Rabbi Michoel Ber Weissmandl Congressional Gold Medal Act of 2017
                ]
        ...

Retrieve a specific package in a collection.

use GovInfo\Api;
use GovInfo\Collection;
use GovInfo\Requestor\CollectionAbstractRequestor;

$api = new Api(
    new \GuzzleHttp\Client(), 
    'DEMO_KEY'
);
$collection = new Collection($api);
$requestor = new CollectionAbstractRequestor();

$requestor
    ->setStrCollectionCode('BILLS')
    ->setObjStartDate(new \DateTime('2018-01-01 12:00:00'))
    ->setObjEndDate(new \DateTime('2018-02-01 12:00:00'))
    ->setStrDocClass('hr')
    ->setStrPackageId('BILLS-115hr4033rfs')
    ->setStrTitle('Geologic Mapping Act');

$result = $collection->item($requestor);

After running this code $result will contain the requested package

Array
(
    [count] => 202767
    [message] => 
    [nextPage] => https://api.govinfo.gov/collections/BILLS/2018-01-01T00:00:00Z/?offset=100&pageSize=100

    [packages] => Array
        [
            [2] => Array
                [
                    [packageId] => BILLS-115hr4033rfs
                    [lastModified] => 2018-11-16T00:33:00Z
                    [packageLink] => https://api.govinfo.gov/packages/BILLS-115hr4033rfs/summary
                    [docClass] => hr
                    [title] => National Geologic Mapping Act Reauthorization Act
                ]
        ]
)

Retrieve a summary of a package.

use GovInfo\Package;
use GovInfo\Requestor\PackageAbstractRequestor;

$package = new Package($api);
$requestor = new PackageAbstractRequestor();

$result = $package->summary($requestor->setStrPackageId('BILLS-115hr4033rfs'));

After running this code $result will contain a non-truncated version of the package summary

Array
(
    [title] => An Act To reauthorize the National Geologic Mapping Act of 1992.
    [shortTitle] => Array
        [
            [0] => Array
                [
                    [type] => measure
                    [title] => National Geologic Mapping Act Reauthorization Act
                ]

        ]
    ...

Retrieve a package as a specified content-type

use GovInfo\Package;
use GovInfo\Requestor\PackageAbstractRequestor;

$package = new Package($api);
$requestor = new PackageAbstractRequestor();
$requestor
    ->setStrPackageId('BILLS-115hr4033rfs')
    ->setStrContentType('xml');

$result = $package->contentType($requestor);

After running this code $result will be an instance of GuzzleHttp\Psr7\Response

For additional usage examples, please look at src/Console and tests.

Console

There is a minimalist console application that can be used, but its not designed for production use. I built this so I could easily regression test the library against the production API. Each command will prompt you for an API key. To avoid this prompt you can create a local apiKey.txt file with your API key in there.

Example

# displays collections
php console.php collection:index

# display packages for a given collection 
php console.php collection:packages

# writes to csv file
php console.php collection:packages --file

# writes to csv file in a specific folder
php console.php collection:packages --file --path=/home/username/Desktop

# retrieves a package summary as a GuzzleHttp\Psr7\Response instance
php console.php package:summary

# retrieves a package summary and writes to file
php console.php package:summary --file

# writes to file in a specific folder
php console.php collection:packages --file --path=/home/username/Desktop
