Procédure pas à pas : Application de bureau API Bing Ads en C#

Cet exemple d’application console C# demande le consentement de l’utilisateur via les informations d’identification que vous fournissez, puis obtient les comptes auxquels l’utilisateur authentifié peut accéder.

Vous devez d’abord inscrire une application et prendre note de l’ID client (ID d’application inscrit). Pour plus d’informations sur l’inscription d’une application et le flux d’octroi du code d’autorisation, consultez Authentification avec OAuth.

Vous aurez également besoin de votre jeton de développeur de production. Vous pouvez créer l’exemple étape par étape comme décrit ci-dessous ou télécharger d’autres exemples à partir de GitHub.

Procédure pas à pas du code

  1. Ouvrez l’environnement de développement Visual Studio Community 2017.

  2. Créer un projet via Fichier ->Nouveau ->Projet

  3. Dans la fenêtre Nouveau projet, choisissez .NET Framework 4.7.1 dans la liste déroulante, puis cliquez sur le modèle Application console (.NET Framework). Nommez le projet BingAdsConsoleApp et cliquez sur OK.

  4. Installez le Kit de développement logiciel (SDK) via NuGet pour BingAdsConsoleApp. Pour plus d’informations sur les dépendances, consultez Installer le Kit de développement logiciel (SDK). Cliquez sur Outils ->Gestionnaire de package NuGet ->Console du Gestionnaire de package. À l’invite, tapez ces commandes pour installer les packages un par un : Install-Package Microsoft.BingAds.SDK, Install-Package System.ServiceModel.Primitives -Version 4.4.1, Install-Package System.ServiceModel.Http -Version 4.4.1et Install-Package System.Configuration.ConfigurationManager -Version 4.4.1.

  5. Ouvrez le fichier App.config et remplacez son contenu par le bloc de code suivant. Modifiez BingAdsEnvironment pour passer du bac à sable à la production. Si vous ciblez l’environnement de production, vous devez remplacer 4c0b021c-00c3-4508-838f-d3127e8167ff par l’ID d’application qui a été provisionné lors de l’inscription de votre application de production et remplacer BBD37VB98 par votre jeton de développeur de production.

Configuration du bac à sable

Pour utiliser le bac à sable, définissez la clé BingAdsEnvironment sur Bac à sable dans le <nœud appSettings> du fichier App.config de la racine de votre projet.

<add key="BingAdsEnvironment" value ="Sandbox"/>

Vous pouvez également définir l’environnement pour chaque ServiceClient individuellement comme suit.

_customerManagementService = new ServiceClient<ICustomerManagementService>(
    _authorizationData, 
    ApiEnvironment.Sandbox
);

Que vous définissiez l’environnement ServiceClient globalement ou individuellement, vous devez également définir l’environnement OAuth sur bac à sable.

var oAuthDesktopMobileAuthCodeGrant = new OAuthDesktopMobileAuthCodeGrant(
    ClientId, 
    ApiEnvironment.Sandbox
);
