GMAIL API-问题服务帐户

问题描述 投票:1回答:1

我已遵循此处描述的所有步骤:https://developers.google.com/identity/protocols/oauth2/service-account

  • 我已经在GSuite中选中了域委派来创建服务帐户。

    Services Account

  • [我已经添加了在GSuite中发送电子邮件的权限。

    GSuite permissions

  • [已将应用添加到受信任的应用中。

  • 已启用gmail API

但是发送邮件时收到以下错误

{
  "code": 400,
  "errors": [
    {
      "domain": "global",
      "message": "Bad Request",
      "reason": "failedPrecondition"
    }
  ],
  "message": "Bad Request"
}

代码:

    private static final String APPLICATION_NAME = "xxxx-send-email";
    private static final GsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance();
    private static final String KEY_FILE_LOCATION = "xxxxx-273014-426ae03a7dbd.p12";
    private static final List<String> scopes = new ArrayList<String>() {
        {
            add(GmailScopes.GMAIL_SEND);
            add(DirectoryScopes.ADMIN_DIRECTORY_USER);
        }
    };

    public static void main(String[] args) {
        try {
            HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();

            GoogleCredential credential = new  GoogleCredential.Builder()
                      .setTransport(httpTransport)
                      .setJsonFactory(JSON_FACTORY)
                      .setServiceAccountId("xxxxxxxx57")
                      .setServiceAccountScopes(scopes)
                      .setServiceAccountPrivateKeyFromP12File(new File(GmailSend.class.getResource(KEY_FILE_LOCATION).getFile()))
                      .build();

            Gmail gmail = new Gmail.Builder(httpTransport, JSON_FACTORY, null).setHttpRequestInitializer(credential).setApplicationName("xxxxxx-send-email").build();

            Message message = new Message();
            message.setRaw(RAW_TEST);
            gmail.users().messages().send(userId, message).execute();
        } catch(Throwable th) {
            th.printStackTrace(System.out);
        }
    }

[构建Gmail服务时,您需要合并服务帐户凭据

更改

Gmail gmail = new Gmail.Builder(httpTransport, JSON_FACTORY, null)

Gmail gmail = new Gmail.Builder(httpTransport, JSON_FACTORY, credential)

也:您的代码中包含了范围DirectoryScopes.ADMIN_DIRECTORY_USER。但是您也没有提及您是否已授予服务帐户相应的权限。
