API 快速入門導覽課程

本頁將說明如何透過用戶端程式庫,以您偏好的程式設計語言開始使用 Google Analytics Data API v1。

步驟 1:啟用 API

按一下這個按鈕來建立新的 Cloud Platform 專案,自動啟用 Google Analytics Data API v1,並建立本教學課程所需的服務帳戶:

啟用 Google Analytics Data API v1

在出現的對話方塊中,按一下「Download CLIENT CONFIGURATION」,並將 credentials.json 檔案儲存到工作目錄。

步驟 2:在 Google Analytics (分析) 4 資源中加入服務帳戶

使用文字編輯器,開啟在上一步下載的 credentials.json 檔案,搜尋 client_email 欄位,取得類似下方的服務帳戶電子郵件地址:

quickstart@PROJECT-ID.iam.gserviceaccount.com

系統會使用這個電子郵件地址,在您要透過 Google Analytics Data API v1 存取的 Google Analytics (分析) 4 資源中新增使用者。本教學課程僅需要檢視者權限。

步驟 3:設定驗證方法

這個應用程式會使用服務帳戶憑證,示範 Google Analytics Data API v1 的使用方式。

如需建立及設定應用程式的服務帳戶憑證的操作說明,請詳閱

如要提供服務帳戶憑證,最簡單的方法是設定 GOOGLE_APPLICATION_CREDENTIALS 環境變數,API 用戶端會使用這個變數的值尋找服務帳戶金鑰 JSON 檔案。

如要在此範例中設定應用程式憑證,請執行下列指令,並使用步驟 1 下載的服務帳戶 JSON 檔案路徑:

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

發出 API 呼叫

您現在可以使用 Google Analytics Data API 查詢 Google Analytics (分析) 4 資源。執行以下程式碼進行首次呼叫 API:

Java

    sampleRunReport(propertyId);
  }

      RunReportResponse response = analyticsData.runReport(request);

      System.out.println("Report result:");
      // Iterate through every row of the API response.

        System.out.printf(
            "%s, %s%n", row.getDimensionValues(0).getValue(), row.getMetricValues(0).getValue());
      }
    }
