Gmail Api服務帳戶給出失敗的先決條件回覆

我正嘗試使用服務帳戶在JUnit測試中簡單發送來自gmail的電子郵件。Gmail Api服務帳戶給出失敗的先決條件回覆

我有這樣的測試：

@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("[email protected]", "Tom Catfish"); 
     InternetAddress from = new InternetAddress("[email protected]", "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... 
}

從而未能與此：

我有一個包含此信息的文件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": "[email protected]", 
    "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" 
}

我怎麼能解決什麼是造成這種愚蠢的，從谷歌沒有幫助failedPrecondition resopnse？

服務器回答以http 400問題是：哪個服務器;您是否使用了代理？你能嗅探網絡流量嗎？ – rds

由於您擁有googleapis客戶端的代碼源，因此可以在AbstractGoogleClientRequest interceptResponse（）中放置breakpint以查看有關響應的更多詳細信息。 – rds
