Recentemente publiquei um artigo sobre Integra\u00e7\u00e3o de gateway de pagamento PayPal em PHP<\/a>. Nesse artigo, um de nossos leitores perguntou sobre a integra\u00e7\u00e3o do gateway de pagamento PayPal no Laravel. Embora o Laravel seja constru\u00eddo usando PHP, eles t\u00eam seus pr\u00f3prios padr\u00f5es a seguir. Voc\u00ea tem que ajustar seu c\u00f3digo PHP simples de acordo com o fluxo do Laravel. Neste artigo, mostrarei como aceitar pagamento em seu site Laravel usando a API Rest do PayPal.<\/p>\n

PayPal \u00e9 uma das marcas mais confi\u00e1veis \u200b\u200bpara aceitar pagamentos online. O PayPal oferece diferentes maneiras de integrar seu sistema de pagamento em aplicativos da web. Um dos servi\u00e7os \u00e9 o PayPal Rest API, que usaremos neste tutorial. Para come\u00e7ar, primeiro voc\u00ea precisa obter seu ID e segredo do cliente.<\/p>\n

V\u00e1 para sua conta de desenvolvedor do PayPal<\/a> e fa\u00e7a login nela. No painel do desenvolvedor, clique no menu ‘Meus aplicativos e credenciais’. Em seguida, clique no bot\u00e3o ‘Criar aplicativo’ na se\u00e7\u00e3o de aplicativos da API REST.<\/p>\n

Siga as etapas conforme solicitado e voc\u00ea obter\u00e1 sua sandbox e credenciais ao vivo. Por enquanto, copie o ID do cliente e o segredo do cliente do modo sandbox.<\/p>\n

\"Integra\u00e7\u00e3o<\/a><\/p>\n

Configura\u00e7\u00e3o b\u00e1sica no Laravel para aceitar pagamento usando PayPal<\/h3>\n

Quando os clientes fazem o pagamento em seu site, voc\u00ea precisa armazenar os detalhes do pagamento para uso posterior. Crie uma tabela de ‘pagamentos’ no banco de dados para armazenar os detalhes do pagamento. Crie uma migra\u00e7\u00e3o para a tabela de ‘pagamentos’ usando o comando:<\/p>\n

php artisan make:migration create_payments_table<\/code><\/pre>\n
Abra o arquivo de migra\u00e7\u00e3o e modifique as colunas conforme a seguir.<\/p>\n
<?php\n...\n...\npublic function up()\n{\n\u00a0\u00a0\u00a0\u00a0Schema::create('payments', function (Blueprint $table) {\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->bigIncrements('id');\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->string('payment_id');\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->string('payer_id');\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->string('payer_email');\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->float('amount', 10, 2);\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->string('currency');\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->string('payment_status');\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0$table->timestamps();\n\u00a0\u00a0\u00a0\u00a0});\n}<\/code><\/pre>\n
Execute a migra\u00e7\u00e3o acima usando o comando abaixo.<\/p>\n
php artisan migrate<\/code><\/pre>\n
Este comando criar\u00e1 uma tabela de ‘pagamentos’ em seu banco de dados. A seguir, crie um modelo correspondente \u00e0 tabela de ‘pagamentos’.<\/p>\n
php artisan make:model Payment<\/code><\/pre>\n
Depois disso, adicione as credenciais do PayPal em seu .env<\/code>arquivo.<\/p>\n
PAYPAL_CLIENT_ID=PASTE_HERE_CLIENT_ID\nPAYPAL_CLIENT_SECRET=PASTE_HERE_CLIENT_SECRET\nPAYPAL_CURRENCY=USD<\/code><\/pre>\n
Limpe o cache de configura\u00e7\u00e3o usando o comando:<\/p>\n
php artisan config:cache<\/code><\/pre>\n
Eu passei a moeda ‘USD’. O usu\u00e1rio pode alter\u00e1-lo de acordo com os requisitos.<\/p>\n
Vamos definir as rotas que vamos exigir nas pr\u00f3ximas etapas.<\/p>\n
rotas \/ web.php<\/strong><\/p>\n
<?php\n...\n...\nRoute::get('payment', 'PaymentController@index');\nRoute::post('charge', 'PaymentController@charge');\nRoute::get('paymentsuccess', 'PaymentController@payment_success');\nRoute::get('paymenterror', 'PaymentController@payment_error');<\/code><\/pre>\n
Integra\u00e7\u00e3o de gateway de pagamento PayPal no Laravel<\/h3>\n
Integrar a API de gateways de pagamento no aplicativo \u00e9 algo bastante complexo. Felizmente, a biblioteca Omnipay facilitou a vida do desenvolvedor. Omnipay<\/a> \u00e9 a biblioteca de processamento de pagamentos mais popular para PHP. Ele fornece um c\u00f3digo f\u00e1cil e limpo para a integra\u00e7\u00e3o de diferentes gateways de pagamento. Instale a biblioteca Omnipay usando o comando:<\/p>\n
composer require league\/omnipay omnipay\/paypal<\/code><\/pre>\n
Agora, crie um controlador PaymentController<\/code>e defina os m\u00e9todos mencionados no arquivo de rota.<\/p>\n
php artisan make:controller PaymentController<\/code><\/pre>\n
