Clientbibliotheken für Error Reporting

Auf dieser Seite werden die ersten Schritte mit den Cloud-Clientbibliotheken für die Stackdriver Error Reporting API beschrieben. Weitere Informationen zu den Clientbibliotheken für Cloud APIs einschließlich der Clientbibliotheken der älteren Google APIs finden Sie unter Erläuterung der Clientbibliotheken.

Clientbibliothek installieren

C#

Weitere Informationen finden Sie unter C#-Entwicklungsumgebung einrichten. 
Install-Package Google.Cloud.ErrorReporting.V1Beta1 -pre

Go

go get cloud.google.com/go/errorreporting

Java

Weitere Informationen finden Sie unter Java-Entwicklungsumgebung einrichten.

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>26.50.0</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:0.174.0-beta'

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

libraryDependencies += "com.google.cloud" % "google-cloud-errorreporting" % "0.174.0-beta"

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

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

Node.js

Weitere Informationen finden Sie unter Node.js-Entwicklungsumgebung einrichten. 
npm install --save @google-cloud/error-reporting

PHP

composer require google/cloud-error-reporting

Python

Weitere Informationen finden Sie unter Python-Entwicklungsumgebung einrichten. 
pip install --upgrade google-cloud-error_reporting

Ruby

Weitere Informationen finden Sie unter Ruby-Entwicklungsumgebung einrichten. 
gem install google-cloud-error_reporting

Authentifizierung einrichten

Wenn Sie die Clientbibliothek ausführen möchten, müssen Sie zuerst die Authentifizierung einrichten. Hierzu erstellen Sie ein Dienstkonto und legen eine Umgebungsvariable fest. Zum Einrichten der Authentifizierung führen Sie die folgenden Schritte aus. Weitere Informationen finden Sie in der Dokumentation zur GCP-Authentifizierung.

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 oder 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.

Clientbibliothek verwenden

Das folgende Beispiel zeigt die Verwendung der Clientbibliothek.

        };
        return new ReportRequest(service, errorEvent, formattedProjectId);
    }

    {
        // Create the report and execute the request.
        ReportRequest request = CreateReportRequest(e);
        request.Execute();
    }
}

Node.js

// Imports the Google Cloud client library

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

// Reports a simple error

PHP

// Imports the Cloud Client Library
