Auf dieser Seite werden die ersten Schritte mit den Cloud-Clientbibliotheken für die Vertex AI Search for Commerce API beschrieben. Clientbibliotheken erleichtern den Zugriff aufGoogle Cloud -APIs mit einer unterstützten Sprache. Sie könnenGoogle Cloud APIs direkt verwenden, indem Sie Rohdatenanfragen an den Server senden. Clientbibliotheken bieten jedoch Vereinfachungen, die den zu schreibenden Code erheblich reduzieren.
Weitere Informationen zu den Cloud-Clientbibliotheken und den älteren Google API-Clientbibliotheken finden Sie unter Erläuterung zu Clientbibliotheken.
Zur Authentifizierung von Aufrufen an Google Cloud APIs unterstützen Clientbibliotheken Standardanmeldedaten für Anwendungen (Application Default Credentials, ADC). Die Bibliotheken suchen nach Anmeldedaten an einer Reihe von definierten Standorten und verwenden diese Anmeldedaten, um Anfragen an die API zu authentifizieren. Mit ADC können Sie Anmeldedaten für Ihre Anwendung in verschiedenen Umgebungen bereitstellen, z. B. in der lokalen Entwicklung oder Produktion, ohne den Anwendungscode ändern zu müssen.

Client libraries make it easier to access\nGoogle Cloud APIs from a supported language. Although you can use\nGoogle Cloud APIs directly by making raw requests to the server, client\nlibraries provide simplifications that significantly reduce the amount of code\nyou need to write.\n\nRead more about the Cloud Client Libraries\nand the older Google API Client Libraries in\n[Client libraries explained](/apis/docs/client-libraries-explained).\n\nInstall the client library\n--------------------------\n\n### C++\n\nSee [Setting up a C++ development environment](/cpp/docs/setup)\nfor details about this client library's requirements and install dependencies.\n\n### C#\n\n\nSee the\n[Reference Page](/dotnet/docs/reference/Google.Cloud.Retail.V2/latest)\nfor this client library's requirements and install dependencies.\n\nFor more information, see [Setting Up a C# Development Environment](/dotnet/docs/setup).\n\n### Go\n\n\nSee the\n[GitHub `README`](https://github.com/googleapis/google-cloud-go/tree/main/retail#readme)\nfor this client library's requirements and install dependencies.\n\nFor more information, see [Setting Up a Go Development Environment](/go/docs/setup).\n\n### Java\n\n\nSee the\n[GitHub `README`](https://github.com/googleapis/google-cloud-java/blob/main/java-retail/README.md)\nfor this client library's requirements and install dependencies.\n\nFor more information, see [Setting Up a Java Development Environment](/java/docs/setup).\n\n### Node.js\n\n\nSee the\n[GitHub `README`](https://github.com/googleapis/google-cloud-node/blob/main/packages/google-cloud-retail/README.md)\nfor this client library's requirements and install dependencies.\n\nFor more information, see [Setting Up a Node.js Development Environment](/nodejs/docs/setup).\n\n### PHP\n\n\nSee the\n[GitHub `README`](https://github.com/googleapis/google-cloud-php/blob/main/Retail/README.md)\nfor this client library's requirements and install dependencies.\n\nFor more information, see [Using PHP on Google Cloud](/php/docs).\n\n### Python\n\n\nSee the\n[PyPI `README`](https://pypi.org/project/google-cloud-retail/) for details about this client library's\nrequirements and install dependencies.\n\nFor more information, see [Setting Up a Python Development Environment](/python/docs/setup).\n\n### Ruby\n\n\nSee the\n[RubyDoc `README`](https://github.com/googleapis/google-cloud-ruby/blob/main/google-cloud-retail/README.md) for details about this client library's\nrequirements and install dependencies.\n\nFor more information, see [Setting Up a Ruby Development Environment](/ruby/docs/setup).\n\n\u003cbr /\u003e\n\nSet up authentication\n---------------------\n\nTo authenticate calls to Google Cloud APIs, client libraries support [Application Default Credentials (ADC)](/docs/authentication/application-default-credentials); the libraries look for credentials in a set of defined locations and use those credentials to authenticate requests to the API. With ADC, you can make credentials available to your application in a variety of environments, such as local development or production, without needing to modify your application code.\n\nFor production environments, the way you set up ADC depends on the service\nand context. For more information, see [Set up Application Default Credentials](/docs/authentication/provide-credentials-adc).\n\nFor a local development environment, you can set up ADC with the credentials\nthat are associated with your Google Account:\n\n1.\n [Install](/sdk/docs/install) the Google Cloud CLI.\n\n After installation,\n [initialize](/sdk/docs/initializing) the Google Cloud CLI by running the following command:\n\n ```bash\n gcloud init\n ```\n\n\n If you're using an external identity provider (IdP), you must first\n [sign in to the gcloud CLI with your federated identity](/iam/docs/workforce-log-in-gcloud).\n2.\n\n If you're using a local shell, then create local authentication credentials for your user\n account:\n\n ```bash\n gcloud auth application-default login\n ```\n\n You don't need to do this if you're using Cloud Shell.\n\n\n If an authentication error is returned, and you are using an external identity provider\n (IdP), confirm that you have\n [signed in to the gcloud CLI with your federated identity](/iam/docs/workforce-log-in-gcloud).\n\n\n A sign-in screen appears. After you sign in, your credentials are stored in the\n [local credential file used by ADC](/docs/authentication/application-default-credentials#personal).\n\nAdditional resources\n--------------------\n\n### C++\n\nThe following list contains links to more resources related to the\nclient library for C++:\n\n- [API reference](https://cloud.google.com/cpp/docs/reference/retail/latest)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-cpp/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D%5Bc%2B%2B%5D)\n- [Source code](https://github.com/googleapis/google-cloud-cpp)\n\n### C#\n\nThe following list contains links to more resources related to the\nclient library for C#:\n\n- [API reference](/dotnet/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-dotnet/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bc%23%5D)\n- [Source code](https://github.com/googleapis/google-cloud-dotnet)\n\n### Go\n\nThe following list contains links to more resources related to the\nclient library for Go:\n\n- [API reference](/go/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-go/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bgo%5D)\n- [Source code](https://github.com/googleapis/google-cloud-go)\n\n### Java\n\nThe following list contains links to more resources related to the\nclient library for Java:\n\n- [API reference](/java/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-java/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bjava%5D)\n- [Source code](https://github.com/googleapis/google-cloud-java)\n\n### Node.js\n\nThe following list contains links to more resources related to the\nclient library for Node.js:\n\n- [API reference](/nodejs/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-node/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bnode.js%5D)\n- [Source code](https://github.com/googleapis/google-cloud-node)\n\n### PHP\n\nThe following list contains links to more resources related to the\nclient library for PHP:\n\n- [API reference](/php/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-php/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bphp%5D)\n- [Source code](https://github.com/googleapis/google-cloud-php)\n\n### Python\n\nThe following list contains links to more resources related to the\nclient library for Python:\n\n- [API reference](/python/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-python/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bpython%5D)\n- [Source code](https://github.com/googleapis/google-cloud-python)\n\n### Ruby\n\nThe following list contains links to more resources related to the\nclient library for Ruby:\n\n- [API reference](/ruby/docs/reference)\n- [Client libraries best practices](/apis/docs/client-libraries-best-practices)\n- [Issue tracker](https://github.com/googleapis/google-cloud-ruby/issues)\n- [`tbd` on Stack Overflow](https://stackoverflow.com/search?q=%5Btbd%5D+%5Bruby%5D)\n- [Source code](https://github.com/googleapis/google-cloud-ruby)\n\n\u003cbr /\u003e"]]
