API 快速入門導覽課程

本頁說明如何在常用的 Google Analytics Data API v1 中開始使用編寫這個程式語言

步�� 1：啟用 API

點選以下按鈕，即可自動建立新的 Google Cloud 專案啟用 Google Analytics Data API v1，並建立本教學課程所需的服務帳戶：

在出現的對話方塊中，按一下「下載用戶端設定」並��存檔案 credentials.json 至工作目錄。

步驟 2：在 Google Analytics 資源中加入服務帳戶

使用文字編輯器開啟下載的 credentials.json 檔案上一個步驟並搜尋 client_email 欄位，以取得服務帳戶電子郵件地址 "quickstart@PROJECT-ID.iam.gserviceaccount.com".

使用這個電子郵件地址新增使用者要使用 Google Analytics Data API v1 存取的 Analytics 資源。在本教學課程中僅限檢視者權限。

步驟 3：設定驗證機制

本應用程式示範如何使用服務帳戶憑證。

瞭解詳情：建立及設定服務帳戶憑證的操作說明應用程式。

如要提供服務帳戶憑證，其中一種方法是設定 GOOGLE_APPLICATION_CREDENTIALS 環境變數 API 用戶端會使用這個變數的值找出服務帳戶金鑰 JSON 檔案

如要設定這個範例中的應用程式憑證，請執行下列指令並使用在步驟 1 下載的服務帳戶 JSON 檔案的路徑：

 export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

例如：

 export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/credentials.json"

步驟 4：安裝用戶端程式庫

Go

go get google.golang.org/genproto/googleapis/analytics/data/v1beta

發出 API 呼叫

您現在可以使用 Google Analytics Data API 查詢 Google Analytics 資源。請執行以下程式碼，對 API 執行第一次呼叫：
