GAE - 当我部署应用程序不起作用，但在localhost上它有效吗？

Question

我使用app编写了一个gae引擎java mail api。

我的appengine-web.xml：

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <application>mailapps</application>
  <version>1</version>

  <!--
    Allows App Engine to send multiple requests to one instance in parallel:
  -->
  <threadsafe>true</threadsafe>

  <!-- Configure java.util.logging -->
  <system-properties>
    <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
  </system-properties>

  <!--
    HTTP Sessions are disabled by default. To enable HTTP sessions specify:

      <sessions-enabled>true</sessions-enabled>

    It's possible to reduce request latency by configuring your application to
    asynchronously write HTTP session data to the datastore:

      <async-session-persistence enabled="true" />

    With this feature enabled, there is a very small chance your app will see
    stale session data. For details, see
    http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions
  -->

</appengine-web-app>

当我在localhost上运行应用程序时，我的一切运行良好，但是当我在gae上运行部署并运行它时，我得到：

  

错误：服务器错误服务器遇到错误而无法解决   完成您的请求。

     

如果问题仍然存在，请报告您的问题并提及此问题   错误消息和导致它的查询。

我的应用程序出了什么问题？你能帮我吗？

1.UPDATE _

gae日志说：

  

java.lang.RuntimeException：javax.mail.SendFailedException：Send   失败（javax.mail.MessagingException：非法参数   （java.lang.IllegalArgumentException：未经授权的发件人：未经授权   发送者））

        String description = req.getParameter("description");
        String email = req.getParameter("email");
        Properties props = new Properties();
        Session session = Session.getDefaultInstance(props, null);
        log.info(description + name + email + " :Daten extrahiert!");
        String msgBody = name  + " :Name der Person" + "\n" + description + " :Beschreibung der Person" + "\n" + email + " :EMAIL";

        try {
            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress("mailapps@gmail.com",
                    "It works"));
            msg.addRecipient(Message.RecipientType.TO, new InternetAddress("maximus@gmail.com", "Your name"));
            msg.setSubject("Bestellung");
            msg.setText(msgBody);
            log.info("Message send!");
            Transport.send(msg);

        } catch (Exception e) {
            resp.setContentType("text/plain");
            resp.getWriter().println("Something went wrong. Please try again.");
            throw new RuntimeException(e);
        }

        resp.setContentType("text/plain");
        resp.getWriter().println(
                "Thanks you for your feedback. An Email has been send out.");
    }
}

这就是servlet！

Answer 1

发件人电子邮件地址有明显的限制。 Google App Engine文档提供了有关此内容的详细信息。

请参阅https://developers.google.com/appengine/docs/java/mail/overview#Sending_Mail

它会为您提供足够的选项供您考虑。

Answer 2

mailapps@gmail.com是否有权使用您的申请？

Answer 3

在控制台中转到 App Engine＆gt;设置＆gt;应用程序设置。将此电子邮件地址添加到授权发件人列表中。出现此问题是因为您从未经授权的电子邮件ID发送电子邮件。

• 你是项目的拥有者并不重要，你必须这样做 在app引擎的应用程序设置中添加发件人电子邮件ID＆gt;＆gt; 设置
