在将邮件发送为中添加其他电子邮件地址 [英] Add another email address in send mail as

问题描述

我想使用Google Gmail API在Send mail as部分添加另一个电子邮件地址。我试过这个代码，有人能帮帮我吗？

SendAs primaryAlias = null;
ListSendAsResponse aliases = service.users().settings().sendAs().list("me").execute();
for (SendAs alias: aliases.getSendAs()) {
   if (alias.getIsPrimary()) {
       primaryAlias = alias;
           break;
   }
}
System.out.println("Updated signature for " + primaryAlias.getDisplayName());
SendAs aliasSettings = new SendAs().setSignature("I heart cats.")
   .setSendAsEmail("[e-mail]");
SendAs r = service.users().settings().sendAs().create("me", aliasSettings).execute();
System.out.println("Updated signature for " + r.getDisplayName());

线程"Main"中出现异常

com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
  "code" : 403,
  "errors" : [ {
    "domain" : "global",
    "message" : "Access restricted to service accounts that have been delegated domain-wide authority",
    "reason" : "forbidden"
  } ],
  "message" : "Access restricted to service accounts that have been delegated domain-wide authority"
}

推荐答案

别名只能由具有全域权限的服务帐号使用Users.settings.sendAs: create创建，可以从documentation中撤回。

请参阅here如何创建服务帐户。您需要创建creadentials并将其存储在驱动器上，例如作为.p12文件。

以下是如何在Java中设置服务帐户的示例：

public class ServiceAccountJava

 {
    private static final String APPLICATION_NAME = "XXX";
    private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();
    private static final List<String> SCOPES = Collections.singletonList(XXX);
    public static void main(String... args)   throws IOException, GeneralSecurityException
{
    final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();                           
     File pk12=new File("XXX.p12");     
     String serviceAccount="[e-mail]";   
//  Builder necessary for the ability to refresh tokens
     GoogleCredential getCredentials = new GoogleCredential.Builder()
      .setTransport(HTTP_TRANSPORT)
      .setJsonFactory(JSON_FACTORY)
      .setServiceAccountId(serviceAccount)
      .setServiceAccountPrivateKeyFromP12File(pk12) //RESOURCES_CLIENT_SECRETS_JSON, SRC_RESOURCES_KEY_P12
      .setServiceAccountScopes(SCOPES)
      .setServiceAccountUser("XXX") //the user whom you want to impersonate
      .build();
       ...
    }
}
