Stock API libphp

Overview

This is a PHP implementation of the various APIs provided by the Stock services. Adobe Stock APIs are available here

Getting Started

1. Use Git to clone the entire repository in the root folder, or export a zip of the repository and extract locally.

2. Or, you can include this repository into your project using composer by adding the following configuration into your composer.json file:

3. Or, you can refer to AdobeStock Sample For SDK to use this SDK in your project in a very handy way.

Prerequisites

To use the SDK you need to check for the following prerequisites:

1. The SDK requires PHP 7.1 or higher. If you do not have that version, install it now.

2. If Composer isn't already installed, install it from here. This is required to download project dependencies for the SDK.

   * For Mac, recommend Homebrew for this:
       * Run `brew install composer`.
       * If you get a message that the lock file is out of date, run `brew update composer`.

Build Steps

• Run composer update to update the composer.lock file to install new dependencies.

• Run composer install --no-dev for installing the required libraries.

  If you plan to do some developement, then remove the --no-dev option If you choose to install those extra dependencies, you must also install xdebug separately or use following steps.

  • On Mac use homebrew to install xdebug:

    • Use brew search xdebug to get the list of available xdebug extensions.
    • From the above list, pick latest xdebug version and run brew install homebrew/php/<php-version>-xdebug ex: brew install homebrew/php/php71-xdebug.
  • On Windows, use following steps to install xdebug :
    • Download xdebug.dll from here.
    • Edit php.ini to use xdebug extension. Steps given here.

Usage

AdobeStock

In order to use the Stock APIs, one must initialize AdobeStock by passing config values like ApiKey, Product, environment which in turn initializes stock Config.

Accessing SearchFiles

SearchFiles

AdobeStock class will allow you to access the Search/Files Stock Api. You can query Adobe Stock for assets that meet your specified search criteria. You can construct the SearchFilesRequest object to set filters, sort order, set search keywords etc. for the Search/Files api.

First, You have to call searchFilesInitialize to initialize search files which will gives you adobe stock object from where you can call getNextResponse, getPreviousResponse etc. to fetch the results. The AdobeStock provides paginated interface which allows you to call its methods (for e.g. getNextResponse, getPreviousResponse etc.) multiple times to retrieve the subsequent search results in order. It maintains the current state of searchFiles request and initially, the state is pointing invalid search files results. As soon as, the getNextReponse method is called, it makes Search/Files api call and returns the results with SearchFilesReponse object. The getNextResponse moves the state to next page and fetch the response for the same. Similarly, the getPreviousResponse and getResponsePage methods can be used to move one page behind and skip to a particular search page index respectively.

Instantiation

You can construct the object of this class with below arguments -

• Requires:

  • access_token - the adobe ims user access token. It must be a valid access token if is_licensed result column is requested with the results. Otherwise, it can be null.
  • request - the request object of SearchFilesRequest consisting the locale, results column, search parameters etc.
• Returns:
  • The response object (SearchFilesResponse) containing the search files api results matching the request object.

Example

Sample code to initialize the SearchFiles Api -

More examples can be found at the end of this document.

Methods

• AdobeStock Methods for file searchcan throw StockException if there are no search results available. It allows you to -

  • getNextResponse - Method to get next search files response page. It moves the state to next page and fetch the searchFiles response for the same. If the api returns with error or if there are no more search results available for the search request, the method will throw the StockException.

  • getPreviousResponse - Method to get previous search files response page. It moves the state to previous page and fetch the searchFiles response for the same. If the api returns with error or if there are no more search results available for the search request or the state is pointing to invalid state, the method will throw the StockException.

  • getResponsePage - Method to skip to a specific search files response page. It moves the state to provided search page and fetch the searchFiles response for the same. It will throw StockException if there is any failure while searchFiles api or if the provided search page index is out of total search pages available.

  • getLastResponse - Get the response object of recently performed searchFiles api call either by using getNextReponse or getPreviousResponse or getResponsePage. Initially, this method will return null since it is pointing to invalid state and no response available at this point.

  • currentSearchPageIndex - Get the current search page index of searchFiles response available from recently performed getNextReponse or getPreviousResponse or getResponsePage method. Initially, since the state is pointing to invalid state, it returns -1.

  • totalSearchPages - Get the total number of search pages available from recently performed getNextReponse or getPreviousResponse or getResponsePage method. Initially, since the state is pointing to invalid state, it returns -1.

  • totalSearchFiles - Get the total number of search files available from recently performed getNextReponse or getPreviousResponse or getResponsePage method. Initially, since the state is pointing to invalid state, it returns -1.

SearchFilesRequest

In order to make SearchFiles API call, you need to create a SearchFileRequest object to define the search criterion for search files results. You can set the various search parameters, locale and required result columns supported by Stock Search/Files api here.

Here is the mapping of Search/Files api query parameters with the setters methods that you can use to set the corresponding parameters in PHP Stock SDK -

SearchParameters

SearchParameters allows to set the various search_parameters (URL query parameters) supported by Search/Files Stock api. This is the class where you can actually set the search keywords, limit, sort order, filters, media_id etc.

Mapping of query parameter search_parameters[*] with SearchParameters class setter methods -

Result Columns

You can create array of ResultColumn enums to define columns that you want to include in your search results.

Example

Note

If you are not setting result columns, it will set following columns in result_column array by default.

• Default Result Columns -
  • NB_RESULTS
  • ID
  • TITLE
  • CREATOR_NAME
  • CREATOR_ID
  • WIDTH
  • HEIGHT
  • THUMBNAIL_URL
  • THUMBNAIL_HTML_TAG

    SearchFilesResponse

    It represents the search results returned with Stock Search/Files API. The SearchFiles class methods for e.g. getNextResponse returns the object of SearchFilesResponse initialized with the results returned from the Search/Files api. SearchFilesResponse allows you to -

• getNbResults - Get the value of 'nb_results' column from the search response
• getFiles - Get the list of StockFile returned by search files api

Making a SearchFilesRequest and Calling search files api

These are the complete examples showing how a search request is created and then search api is called, which in turn returns search results in the form of serchFileRequest.

• Example to get search results by calling getNextResponse method:

• Example to get previous search results by calling getPreviousResponse method:

• Example to skip to specific page of results by calling getResponsePage method:

Accessing SearchCategory

SearchCategory

AdobeStock class allows you to access the Search/Category and Search/CategoryTree Stock APIs. Each stock asset is placed into a category that classifies the asset, such as "Travel" or "Hobbies and Leisure" and each category has a unique identifying number, a name, and a path that you can use to access other assets in the same category.

You can construct the SearchCategoryRequest object to set category identifier and locale information. Then you can call searchCategory method to get information about a category of stock assets in the form of SearchCategoryResponse object. You can also call searchCategoryTree method to retrieve information for zero or more category identifiers in the form of list of SearchCategoryResponse object.

Instantiation

You can construct the object of this class with below arguments -

• Requires: config - the stock configuration object of Config type.

• Returns: SearchCategoryResponse - The response object containing the search category API results matching the request object returned by searchCategory method. List of SearchCategoryResponse - The list of response object containing the search category tree API results matching the request object returned by searchCategoryTree method.

Example

Sample code to instantiate the SearchCategory API -

Methods

• AdobeStock class methods can throw StockApiException if request is not valid or API returns with an error. It allows you to -

  • searchCategory - Method to get information about a category of Stock assets, such as travel or animals for a specified category identifier, optionally localized. You need to pass SearchCategoryRequest object containing category identifier and locale(optional) parameters. If the request object is not valid or API returns with error, the method will throw the StockApiException.

  • searchCategoryTree - Method to get category information for zero or more category identifiers. You need to pass SearchCategoryRequest object containing category identifier and locale parameters (both optional). If request object does not contain category identifier, this returns a list of all stock categories. If the request object is not valid or API returns with error, the method will throw the StockApiException.

SearchCategoryRequest

In order to make SearchCategory/SearchCategoryTree API call, you need to create a SearchCategoryRequest object to define the search criterion for search category results. You can set category identifier and location language code supported by Stock Search Category/Category Tree API here.

Here is the mapping of Search Category/CategoryTree API query parameters with the setters methods that you can use to set the corresponding parameters in PHP Stock SDK -

SearchCategoryResponse

It represents the search result returned from Stock Search/Category API. The AdobeStock class methods for e.g. searchCategory returns the object of SearchCategoryResponse initialized with the results returned from the Search/Category API. SearchCategoryResponse allows you to -

• getId - Get unique identifier of the category returned by search/category API
• getLink - Get path of the category returned by search/category API

Accessing Files Metadata

Files

AdobeStock class allows you to access the Files Stock APIs. The Files API is used to retrieve metadata from Adobe Stock, either one asset at a time, or in bulk.

You can construct the \AdobeStock\Api\Request\Files object to set identifiers, locale information and desired result columns. Then you can call getFiles method to get metadata about the requested file ids in the form of \AdobeStock\Api\Response\Files object.

Instantiation

You can construct the object of this class with below arguments -

• Requires: config - the stock configuration object of Config type.

• Returns: \AdobeStock\Api\Response\Files - The response object containing the files API results matching the request object, returned by getFiles method.

  • getFiles - Method to get metadata information about Stock Files. You need to pass \AdobeStock\Api\Request\Files object containing files identifiers, locale(optional) and result_columns(optional) parameters. If the request object is not valid or API returns with error, the method will throw the StockApiException.

FilesRequest

In order to make GetFiles API call, you need to create a \AdobeStock\Api\Request\Files object to define the ids of the files that you are looking for metadata. You can set files identifiers, location language code and result columns supported by Bulk metadata Files API.

Here is the mapping of Files API query parameters with the setters methods that you can use to set the corresponding parameters in PHP Stock SDK -

Note

If you are not setting result columns, it will set following columns in result_columns array by default.

• Default Result Columns -

You need to pass ims user accessToken and LicenseRequest object containing content_id and license state. If request is not valid or asset is not licensed or licensing information is not present for the asset or API returns with an error, the method will throw the StockApiException.
  • downloadAssetUrl provides the URL of the asset if it is already licensed otherwise throws StockApiException showing a message whether user has enough quota and can buy the license or not. You need to pass ims user accessToken and LicenseRequest object containing content_id and license state. If request is not valid or asset is not licensed or licensing information is not present for the asset or API returns with an error, the method will throw the StockApiException.
    • downloadAssetStream provides the Image Buffer of the asset if it is already licensed otherwise throws StockApiException showing a message whether user has enough quota and can buy the license or not.

Accessing LicenseHistory

LicenseHistory

AdobeStock class will allow you to access the LicenseHistory Api. You can construct the LicenseHistoryRequest object to set offset, limit, set result columns etc. for the LicenseHistory api.

First, You have to call initializeLicenseHistory to initialize license history api which will gives you adobe stock object from where you can call getNextLicenseHistory, getPreviousLicenseHistory etc. to fetch the results. The AdobeStock provides paginated interface which allows you to call its methods (for e.g. getNextLicenseHistory, getPreviousLicenseHistory etc.) multiple times to retrieve the subsequent results in order. It maintains the current state of LicenseHistory request and initially, the state is pointing invalid LicenseHistory files results. As soon as, the getNextLicenseHistory method is called, it makes LicenseHistory api call and returns the results with LicenseHistoryResponse object. The getNextLicenseHistory moves the state to next page and fetch the response for the same. Similarly, the getPreviousLicenseHistory and getLicenseHistoryPage methods can be used to move one page behind and skip to a particular LicenseHistory page index respectively.

Instantiation

You can construct the object of this class with below arguments -

• Requires:

If the api returns with error or if there are no more search results available for the request, the method will throw the StockException.

  • getPreviousLicenseHistory - Method to get previous LicenseHistory files response page. It moves the state to previous page and fetch the LicenseHistory response for the same. If the api returns with error or if there are no more search results available for the request or the state is pointing to invalid state, the method will throw the StockException.

  • getLicenseHistoryPage - Method to skip to a specific LicenseHistory files response page. It moves the state to provided LicenseHistory page and fetch the LicenseHistory response for the same. It will throw StockException if there is any failure while LicenseHistory api or if the provided licenseHistory page index is out of total pages available.

  • getLastLicenseHistory - Get the response object of recently performed LicenseHistory api call either by using getNextLicenseHistory or getPreviousLicenseHistory or getLicenseHistoryPage. Initially, this method will return null since it is pointing to invalid state and no response available at this point.

Testing and Linting

Tests

Run composer run check for linting and testcases. Run composer run test-coverage for test coverage.

The above command will by default run the linting, test cases and the code coverage along with building the project. The linting results will be shown within the console output itself and if there are any issues the build will stop and fail instantly. If there are no linting issues found, the build will continue to build the project. It will also generate the detailed coverage reports for you.

• The coverage report can be found at <project directory>/data/clover/index.html Note - Since the test and coverage steps come later in the build process than linting, so if linting fails, you won't get the coverage reports.

Lint with PHP_CodeSniffer

This project uses PHP_CodeSniffer for linting. In addition, Adobe Stock has a custom set of rules for PHPCS that are included in this repository in the libs directory. This module will be installed when running composer install. It includes a bundled version of PHPCS which may be different from the one you have installed globally; the Composer script will run the correct version.

Linting checks are enforced with the build step itself. By default, the linting will run first and if there are any issues the build will fail.

Running Test Suites

However, the composer run check will run the tests automatically but if you need to run the tests separately, please run the below command in console -

Coverage

Just run the composer run test-coverage as mentioned above, it should generate the coverage reports along with the test results and building the project. As mentioned above coverage reports can be found at <project directory>/data/clover/index.html
