Gmail api客户端库无法向java发送电子邮件

我正在尝试使用java客户端api发送电子邮件。无论我尝试什么，都会出现以下json错误：

{
    "code": 403,
    "errors": [
        {
            "domain": "global",
            "message": "Invalid user id specified in request/Delegation denied",
            "reason": "forbidden"
        }
    ],
    "message": "Invalid user id specified in request/Delegation denied"
}

有没有办法绕过这个错误

与特定问题相关的代码，创建MIME消息，然后根据需要创建相应的消息：

@Path("/sendmessage/{to}/{from}/{subject}/{body}/{userID}")
    @GET
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public Response sendMessage(
            @PathParam("to")String to, 
            @PathParam("from") String from, 
            @PathParam("subject") String subject, 
            @PathParam("body") String body,
            @PathParam("userID") String userID)
    {
            MimeMessage mimeMessage =null;
                Message message = null;

                mimeMessage =createEmail(to, from, subject, body);
                message = createMessageWithEmail(mimeMessage);
                gmail.users().messages().send(userID,message).execute();
resp = Response.status(200).entity(message.toPrettyString()).build();

return resp;
}

public static MimeMessage createEmail(String to, String from, String subject, String bodyText){

          Properties props = new Properties();
          String host = "smtp.gmail.com";
            props.put("mail.smtp.starttls.enable", "true");
            props.put("mail.smtp.host", "smtp.gmail.com");
            props.put("mail.smtp.user", from);
            props.put("mail.smtp.password", "******");
            props.put("mail.smtp.port", "587");
            props.put("mail.smtp.auth", "true");

            Session session = Session.getDefaultInstance(props);

          MimeMessage email = new MimeMessage(session);
          try{
            InternetAddress toAddress = new InternetAddress(to);
            InternetAddress fromAddress = new InternetAddress(from);

            email.setFrom(fromAddress);
            email.addRecipient(javax.mail.Message.RecipientType.TO, toAddress);
            email.setSubject(subject);
            email.setText(bodyText);

            Transport transport = session.getTransport("smtp");
            transport.connect(host, from, ********);
            transport.sendMessage(email, email.getAllRecipients());
            transport.close();
           }
           catch(Exception e){
               LOGGER.error("Class: "+className+", Method: "+methodName+", "+e.getMessage());

           }
            return email;
      }

 public static Message createMessageWithEmail(MimeMessage email){
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try {
            email.writeTo(baos);
        } catch (IOException | MessagingException e) {
            LOGGER.error("Class: "+className+", Method: "+methodName+", "+e.getMessage());
        }
        String encodedEmail = Base64.encodeBase64URLSafeString(baos.toByteArray());
        Message message = new Message();
        message.setRaw(encodedEmail);
        return message;
      }

在Gmail API调用中传递空字符串或“me”作为用户ID：

gmail.users（）.messages（）.send（“，message）.execute（）
在Gmail API调用中传递空字符串或“me”作为用户ID：

gmail.users（）.messages（）.send（“，message）.execute（）
通常，当经过身份验证的电子邮件地址与发件人电子邮件地址不匹配时，会发生此类错误

所以，若您使用的是客户机库，那个么在执行时传递“me”或空字符串，如下所示

gmail.users（）.messages（）.send（“我”，message.execute（）

如果您使用的是RESTAPI，那么使用

me/消息

欢迎使用堆栈溢出API SICOA！你能告诉我们你的相关代码在哪里发送邮件吗？用户id是否丢失或无效？这真是一个愚蠢的问题，在我看来，“userID”是无用的，并且与“from”属性混淆了。移除它，使它“从”和它的作品一直。谢谢大家的帮助和解答，欢迎来到Stack Overflow API SICOA！你能告诉我们你的相关代码在哪里发送邮件吗？用户id是否丢失或无效？这真是一个愚蠢的问题，在我看来，“userID”是无用的，并且与“from”属性混淆了。移除它，使它“从”和它的作品一直。谢谢大家的帮助和回答谢谢先生，我会在周一试试这个，然后留下反馈谢谢先生，我会在周一试试这个，然后留下反馈这从2018年起就不再起作用了（尽管过时的文件说它仍然起作用）。这从2018年起就不再起作用了（尽管过时的文件表明它仍然存在）。
