Library klien Document AI Warehouse

Halaman ini menunjukkan cara memulai Library Klien Cloud untuk Document AI Warehouse API. Library klien mempermudah aksesGoogle Cloud API dari bahasa yang didukung. Meskipun Anda dapat menggunakanGoogle Cloud API secara langsung dengan membuat permintaan mentah ke server, library klien memberikan penyederhanaan yang secara signifikan mengurangi jumlah kode yang perlu ditulis.

Pratinjau

Library ini tunduk pada "Persyaratan Penawaran Pra-GA" di bagian Persyaratan Layanan Umum dari Persyaratan Khusus Layanan. Library pra-GA tersedia "sebagaimana adanya" dan mungkin memiliki dukungan terbatas. Untuk mengetahui informasi selengkapnya, lihat deskripsi tahap peluncuran.

Menginstal library klien

C++

Lihat Menyiapkan lingkungan pengembangan C++ untuk mengetahui detail tentang persyaratan library klien ini dan menginstal dependensi.

Java

If you are using Maven, add the following to your pom.xml file. For more information about BOMs, see The Google Cloud Platform Libraries BOM.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.76.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-contentwarehouse</artifactId>
  </dependency>
</dependencies>

If you are using Gradle, add the following to your dependencies:

implementation 'com.google.cloud:google-cloud-contentwarehouse:0.81.0'

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-contentwarehouse" % "0.81.0"

If you're using Visual Studio Code or IntelliJ, you can add client libraries to your project using the following IDE plugins:

• Cloud Code for VS Code
• Cloud Code for IntelliJ

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.

Note: Cloud Java client libraries do not currently support Android.

Untuk mengetahui informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Java.

Node.js

npm install @google-cloud/contentwarehouse

Untuk mengetahui informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Node.js.

Python

pip install --upgrade google-cloud-contentwarehouse

Untuk mengetahui informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Python.

Menyiapkan autentikasi

Untuk mengautentikasi panggilan ke Google Cloud API, library klien mendukung Kredensial Default Aplikasi (ADC). Library ini mencari kredensial dalam kumpulan lokasi yang ditentukan dan menggunakan kredensial tersebut untuk mengautentikasi permintaan ke API. Dengan ADC, Anda dapat menyediakan kredensial untuk aplikasi di berbagai lingkungan, seperti produksi atau pengembangan lokal, tanpa perlu mengubah kode aplikasi.

Untuk lingkungan produksi, cara menyiapkan ADC bergantung pada layanan dan konteksnya. Untuk mengetahui informasi selengkapnya, lihat Menyiapkan Kredensial Default Aplikasi.

Untuk lingkungan pengembangan lokal, Anda dapat menyiapkan ADC dengan kredensial yang terkait dengan Akun Google Anda:

1. Install the Google Cloud CLI. After installation, initialize the Google Cloud CLI by running the following command:

   gcloud init

   If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

2. If you're using a local shell, then create local authentication credentials for your user account:

   gcloud auth application-default login

   You don't need to do this if you're using Cloud Shell.

   If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

   Layar login akan muncul. Setelah Anda login, kredensial Anda akan disimpan dalam file kredensial lokal yang digunakan oleh ADC.

Menggunakan library klien

Contoh berikut menunjukkan cara menggunakan library klien.

C++

#include "google/cloud/contentwarehouse/v1/document_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-number location-id\n";
    return 1;
  }

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace contentwarehouse = ::google::cloud::contentwarehouse_v1;
  auto client = contentwarehouse::DocumentServiceClient(
      contentwarehouse::MakeDocumentServiceConnection());

  for (auto md : client.SearchDocuments(location.FullName())) {
    if (!md) throw std::move(md).status();
    std::cout << md->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}
