无法验证 google recaptcha 企业。收到错误：
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.
我还使用服务帐户创建了凭证 json 并在环境变量 GOOGLE_APPLICATION_CREDENTIALS 中设置，或者使用 aws 外部帐户创建了凭证 json 并在环境变量中设置。但是必须指定“我正在获取所需的参数”错误注意：我能够从客户端获取令牌，但此错误来自服务器端。
用于获取凭据的代码块： 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());
}
