K\u00fcrzlich habe ich einen Artikel \u00fcber die Integration<\/a> von PayPal Payment Gateway in PHP ver\u00f6ffentlicht<\/a>. In diesem Artikel fragte einer unserer Leser nach der Integration des PayPal-Zahlungsgateways in Laravel. Obwohl Laravel mit PHP erstellt wurde, m\u00fcssen sie ihren eigenen Standards folgen. Sie m\u00fcssen Ihren einfachen PHP-Code gem\u00e4\u00df Laravel-Flow anpassen. In diesem Artikel zeige ich Ihnen, wie Sie Zahlungen auf Ihrer Laravel-Website mit der PayPal Rest API akzeptieren.<\/p>\n

PayPal ist eine der vertrauensw\u00fcrdigsten Marken, die Online-Zahlungen akzeptiert. PayPal bietet verschiedene M\u00f6glichkeiten, sein Zahlungssystem in Webanwendungen zu integrieren. Einer der Dienste ist die PayPal Rest API, die wir f\u00fcr dieses Tutorial verwenden werden. Um zu beginnen, m\u00fcssen Sie zuerst Ihre Client-ID und Ihr Client-Geheimnis abrufen.<\/p>\n

Gehen Sie zu Ihrem PayPal-Entwicklerkonto<\/a> und melden Sie sich dort an. Klicken Sie im Entwickler-Dashboard auf das Men\u00fc "Meine Apps & Zugangsdaten". Klicken Sie dann im Abschnitt REST-API-Apps auf die Schaltfl\u00e4che "App erstellen".<\/p>\n

Befolgen Sie die Anweisungen, und Sie erhalten Ihre Sandbox- und Live-Anmeldeinformationen. Kopieren Sie zun\u00e4chst die Client-ID und das Client-Geheimnis des Sandbox-Modus.<\/p>\n

\"PayPal<\/a><\/p>\n

Grundlegende Einrichtung in Laravel, um Zahlungen mit PayPal zu akzeptieren<\/h3>\n

Wenn Kunden die Zahlung auf Ihrer Website vornehmen, m\u00fcssen Sie die Zahlungsdaten zur sp\u00e4teren Verwendung speichern. Erstellen Sie in der Datenbank eine Tabelle "Zahlungen", um die Zahlungsdetails zu speichern. Erstellen Sie eine Migration f\u00fcr die Tabelle "Zahlungen" mit dem Befehl:<\/p>\n

php artisan make:migration create_payments_table<\/code><\/pre>\n
\u00d6ffnen Sie die Migrationsdatei und \u00e4ndern Sie die Spalten wie folgt.<\/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
F\u00fchren Sie die obige Migration mit dem folgenden Befehl aus.<\/p>\n
php artisan migrate<\/code><\/pre>\n
Dieser Befehl erstellt eine Tabelle "Zahlungen" in Ihrer Datenbank. Erstellen Sie als N\u00e4chstes ein Modell, das der Tabelle "Zahlungen" entspricht.<\/p>\n
php artisan make:model Payment<\/code><\/pre>\n
F\u00fcgen Sie anschlie\u00dfend die PayPal-Anmeldeinformationen in Ihre .env<\/code>Datei ein.<\/p>\n
PAYPAL_CLIENT_ID=PASTE_HERE_CLIENT_ID\nPAYPAL_CLIENT_SECRET=PASTE_HERE_CLIENT_SECRET\nPAYPAL_CURRENCY=USD<\/code><\/pre>\n
L\u00f6schen Sie den Konfigurationscache mit dem Befehl:<\/p>\n
php artisan config:cache<\/code><\/pre>\n
Ich habe die W\u00e4hrung ‚USD‘ bestanden. Der Benutzer kann es nach Bedarf \u00e4ndern.<\/p>\n
Lassen Sie uns die Routen definieren, die wir in den n\u00e4chsten Schritten ben\u00f6tigen.<\/p>\n
routen\/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
PayPal Payment Gateway-Integration in Laravel<\/h3>\n
Die Integration der API f\u00fcr Zahlungsgateways in die Anwendung ist ziemlich komplex. Gl\u00fccklicherweise hat die Omnipay-Bibliothek den Entwicklern das Leben leicht gemacht. Omnipay<\/a> ist die beliebteste Zahlungsverarbeitungsbibliothek f\u00fcr PHP. Es gibt einen einfachen und sauberen Code f\u00fcr die Integration verschiedener Zahlungsgateways. Installieren Sie die Omnipay-Bibliothek mit dem Befehl:<\/p>\n
composer require league\/omnipay omnipay\/paypal<\/code><\/pre>\n
Erstellen Sie nun einen Controller PaymentController<\/code>und definieren Sie die in der Routendatei genannten Methoden.<\/p>\n
php artisan make:controller PaymentController<\/code><\/pre>\n
