Error Reporting クライアント ライブラリ

このページでは、Stackdriver Error Reporting API の Cloud クライアント ライブラリの使用方法を示します。以前の Google API クライアント ライブラリを含む、Cloud API のクライアント ライブラリの詳細については、クライアント ライブラリの説明をご覧ください。

クライアント ライブラリのインストール

C#

詳細については、C# 開発環境の設定をご覧ください。

Install-Package Google.Cloud.ErrorReporting.V1Beta1 -pre

Go

go get cloud.google.com/go/errorreporting

Java

詳細については、Java 開発環境の設定をご覧ください。

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>26.49.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

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

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

implementation 'com.google.cloud:google-cloud-errorreporting:0.173.0-beta'

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

libraryDependencies += "com.google.cloud" % "google-cloud-errorreporting" % "0.173.0-beta"

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

• Cloud Code for VS Code
• Cloud Code for IntelliJ
• Cloud Tools for Eclipse

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

Node.js

詳細については、Node.js 開発環境の設定をご覧ください。

npm install --save @google-cloud/error-reporting

PHP

composer require google/cloud-error-reporting

Python

詳細については、Python 開発環境の設定をご覧ください。

pip install --upgrade google-cloud-error_reporting

Ruby

詳細については、Ruby 開発環境の設定をご覧ください。

gem install google-cloud-error_reporting

認証の設定

クライアント ライブラリを実行するには、サービス アカウントを作成して環境変数を設定し、認証を設定する必要があります。以下の手順で認証を設定します。詳細については、GCP 認証のドキュメントをご覧ください。

Provide authentication credentials to your application code by setting the environment variable GOOGLE_APPLICATION_CREDENTIALS. This variable applies only to your current shell session. If you want the variable to apply to future shell sessions, set the variable in your shell startup file, for example in the ~/.bashrc or ~/.profile file.

Linux または macOS

export GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

Replace KEY_PATH with the path of the JSON file that contains your credentials.

For example:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/service-account-file.json"

Windows

For PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

Replace KEY_PATH with the path of the JSON file that contains your credentials.

For example:

$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\service-account-file.json"

For command prompt:

set GOOGLE_APPLICATION_CREDENTIALS=KEY_PATH

Replace KEY_PATH with the path of the JSON file that contains your credentials.

// Imports the Google Cloud client library
const ErrorReporting = require('@google-cloud/error-reporting')
  .ErrorReporting;

// On Node 6+ the following syntax can be used instead:
// const {ErrorReporting} = require('@google-cloud/error-reporting');

// With ES6 style imports via TypeScript or Babel, the following
// syntax can be used instead:
// import {ErrorReporting} from '@google-cloud/error-reporting';

// Instantiates a client
const errors = new ErrorReporting();

// Reports a simple error
errors.report('Something broke!');
