如何在Laravel 6中使用DocuSign。*

composer require docusign/esign-client

return [
    'integrator_key' => 'YOUR_INTEGRATOR_KEY',
    'username' => 'YOUR_USERNAME',
    'password' => 'YOUR_PASSWORD',
    'base_path' => 'https://demo.docusign.net/restapi',
];

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use DocuSign\eSign\Client\ApiClient;

class DocuSignServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton(ApiClient::class, function ($app) {
            $config = $app['config']['docusign'];
            $apiClient = new ApiClient($config['base_path']);
            $apiClient->getOAuth()->setBasePath($config['base_path']);
            $apiClient->configureJWTAuthorizationFlow(
                $config['integrator_key'],
                $config['username'],
                $config['password'],
                storage_path('docusign')
            );
            return $apiClient;
        });
