Error Reporting 客户端库

本页面介绍了如何开始使用 Stackdriver Error Reporting API 的 Cloud 客户端库。如需详细了解 Cloud API 的客户端库（包括旧版 Google API 客户端库），请参阅客户端库说明。

安装客户端库

C#

如需了解详情，请参阅设置 C# 开发环境。

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

Go

go get cloud.google.com/go/errorreporting

Java

如需了解详情，请参阅设置 Java 开发环境。

如果您使用的是 Maven，请将以下代码添加到您的 pom.xml 文件中。如需详细了解 BOM，请参阅 Google Cloud Platform 库 BOM。

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.19.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

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

如果您使用的是 Gradle，请将以下代码添加到您的依赖项中：

implementation 'com.google.cloud:google-cloud-errorreporting:0.144.0-beta'

如果您使用的是 sbt，请将以下代码添加到您的依赖项中：

libraryDependencies += "com.google.cloud" % "google-cloud-errorreporting" % "0.144.0-beta"

如果您使用的是 Visual Studio Code、IntelliJ 或 Eclipse，可以通过以下 IDE 插件将客户端库添加到您的项目中：

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

上述插件还提供其他功能，例如服务账号密钥管理。如需了解详情，请参阅各个插件相应的文档。

Node.js

如需了解详情，请参阅设置 Node.js 开发环境。

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

PHP

composer require google/cloud-error-reporting

Python

如需了解详情，请参阅设置 Python 开发环境。

pip install --upgrade google-cloud-error_reporting

Ruby

如需了解详情，请参阅设置 Ruby 开发环境。

gem install google-cloud-error_reporting

设置身份验证

要运行客户端库，必须先通过创建服务帐号并设置环境变量来设置身份验证。完成以下步骤即可设置身份验证。如需了解详情，请参阅 GCP 身份验证文档。

通过设置环境变量 GOOGLE_APPLICATION_CREDENTIALS 向应用代码提供身份验证凭据。此变量仅适用于当前的 Shell 会话。如果您希望变量应用于未来的 Shell 会话，请在 shell 启动文件中设置变量，例如在 ~/.bashrc 或 ~/.profile 文件中。

Linux 或 macOS

export GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

将 KEY_PATH 替换为包含您的服务帐号密钥的 JSON 文件的路径。

例如：

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

Windows

对于 PowerShell：

$env:GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"

将 KEY_PATH 替换为包含您的服务帐号密钥的 JSON 文件的路径。

例如：

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

对于命令提示符：

set GOOGLE_APPLICATION_CREDENTIALS=KEY_PATH

将 KEY_PATH 替换为包含您的服务帐号密钥的 JSON 文件的路径。

使用客户端库

以下示例展示了如何使用客户端库。

// Imports the Google Cloud client library

// On Node 6+ the following syntax can be used instead:

// With ES6 style imports via TypeScript or Babel, the following

// Instantiates a client

// Reports a simple error
