java - Gmail Api 服务帐户提供失败的前提条件响应

Question

我正在尝试使用服务帐户在 JUnit 测试中简单地从 gmail 发送电子邮件。

我有这个测试:

@Test
public void testGmailCredential() throws GeneralSecurityException, URISyntaxException {
    try {
        InputStream is = getClass().getClassLoader().getResourceAsStream("myProject.json");
        GoogleCredential credential = GoogleCredential.fromStream(is).createScoped(GmailScopes.all());

        System.out.println("Scopes are " + credential.getServiceAccountScopesAsString());

        Gmail gmailService = new Gmail.Builder(getHttpTransport(), JSON_FACTORY, credential)
                  .setApplicationName("WHAT SHOULD THIS VALUE BE?")
                  //.setHttpRequestInitializer(credential)
                  .build();

        InternetAddress to = new InternetAddress("myemail@myurl.com", "Tom Catfish");
        InternetAddress from = new InternetAddress("myServiceAccountId@xxxxxxxxxx.iam.gserviceaccount.com", "Some Name");

        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);

        MimeMessage email = new MimeMessage(session);

        email.setFrom(from);
        email.addRecipient(javax.mail.Message.RecipientType.TO, to);
        email.setSubject("Subject here");
        email.setText("body here");

        ByteArrayOutputStream buffer = new ByteArrayOutputStream();
        email.writeTo(buffer);
        byte[] bytes = buffer.toByteArray();
        String encodedEmail = Base64.getUrlEncoder().encodeToString(bytes);
        Message message = new Message();
        message.setRaw(encodedEmail);     
        message = gmailService.users().messages().send("me", message).execute();

        System.out.println("Message id: " + message.getId());
        System.out.println(message.toPrettyString());
        // other code...
}

这失败了:

我有包含以下信息的文件 src/test/resources/myProject.json:

{
  "type": "service_account",
  "project_id": "xxxxxxxxxxx",
  "private_key_id": "28341330...",
  "private_key": "-----BEGIN PRIVATE KEY-----\.........\n-----END PRIVATE KEY-----\n",
  "client_email": "myServiceAccountId@xxxxxxxxxx.iam.gserviceaccount.com",
  "client_id": "1182....",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/myApp%40xxxxxxx.iam.gserviceaccount.com"
}

我该如何排查导致 Google 发出这种愚蠢且无用的 failedPrecondition 响应的原因？

对于400 bad request，我已经给出了答案。你可以通过这个。
