無法驗證 google recaptcha 企業。 收到錯誤：java.io.IOException：應用程序默認憑據不可用

Question

無法驗證 google recaptcha 企業。 收到錯誤：

java.io.IOException: The Application Default Credentials are not available.

java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. 

我還使用服務帳戶創建了憑證 json 並在環境變量 GOOGLE_APPLICATION_CREDENTIALS 中設置，或者使用 aws 外部帳戶創建了憑證 json 並在環境變量中設置。 但是必須指定“我正在獲取所需的參數”錯誤注意：我能夠從客戶端獲取令牌，但此錯誤來自服務器端。

用於獲取憑據的代碼塊： Method1 ：

  // If you don't specify credentials when constructing the client, the client library will
  // look for credentials via the environment variable GOOGLE_APPLICATION_CREDENTIALS.
  Storage storage = StorageOptions.getDefaultInstance().getService();

  System.out.println("Buckets:");
  Page<Bucket> buckets = storage.list();
for (Bucket bucket : buckets.iterateAll()) {
    System.out.println(bucket.toString());
  }

方法2：

System.setProperty("GOOGLE_APPLICATION_CREDENTIALS", jsonPath);
System.out.println("GOOGLE_APPLICATION_CREDENTIALS");
System.out.println(System.getProperty("GOOGLE_APPLICATION_CREDENTIALS"));
FileInputStream fileInputStream = new FileInputStream(jsonPath);
  GoogleCredentials credentials = GoogleCredentials.fromStream(fileInputStream)
        .createScoped(Lists.newArrayList("https://www.googleapis.com/auth/cloud-platform"));
  Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();

  System.out.println("Buckets:");
  Page<Bucket> buckets = storage.list();
  for (Bucket bucket : buckets.iterateAll()) {
    System.out.println(bucket.toString());
  }

Answer 1

我能夠使用 recaptcha V3 而不是企業版來實現相同的目標。 由於我們必須實現基於分數的評估，V3 支持基於分數的驗證。
