我如何从Java的MS Exchange Server以编程方式获取电子邮件标题？ [英] How I can get email headers programmatically from MS Exchange Server in Java?

问题描述

我无法访问电子邮件中的标题。在那一刻，我只能得到ExtendedPropertyCollection对象，但我不知道如何使用它。

  ItemEvent item =（ ItemEvent）事件; 
 EmailMessage message = EmailMessage.bind（args.getSubscription（）。getService（），item.getItemId（））; 
 ExtendedPropertyCollection extendedProperties =（（ExtendedPropertyCollection）message.getExtendedProperties（））; 
  

更新：

Java中的结果代码如下所示：

  PropertySet propertySet = new PropertySet（BasePropertySet.FirstClassProperties，ItemSchema.MimeContent）; 
 EmailMessage消息= EmailMessage.bind（args.getSubscription（）。getService（），item.getItemId（），propertySet）; 
 String emailTextWithHeaders = new String（message.getMimeContent（）。getContent（））; 
  

解决方案

有两种方法可以做到这一点，您应该可以访问EmailMessage类的InternetMessageHeader集合 https://github.com/OfficeDev/ews-java-api/blob/master/src/main/java/microsoft/exchange/webservices/data/InternetMessageHeader.java

另一种方法是使用PR_TRANSPORT_MESSAGE_HEADERS扩展属性，例如

  ExtendedPropertyDefinition PR_TRANSPORT_MESSAGE_HEADERS =新的ExtendedPropertyDefinition（0x007D，MapiPropertyType.String）; 
 PropertySet psPropSet = new PropertySet（BasePropertySet.FirstClassProperties）{PR_TRANSPORT_MESSAGE_HEADERS}; 
 EmailMessage message = EmailMessage.bind（args.getSubscription（）。getService（），item.getItemId（），psPropSet）;

I can't get access to headers in email. At that moment I can get only ExtendedPropertyCollection object, but I don't know how to work with it.

ItemEvent item = (ItemEvent) event;
EmailMessage message = EmailMessage.bind(args.getSubscription().getService(), item.getItemId());
ExtendedPropertyCollection extendedProperties = ((ExtendedPropertyCollection) message.getExtendedProperties());

UPDATE:

The result code in Java looks like:

PropertySet propertySet = new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.MimeContent);
EmailMessage message = EmailMessage.bind(args.getSubscription().getService(), item.getItemId(), propertySet);
String emailTextWithHeaders = new String(message.getMimeContent().getContent());

解决方案

There are two ways to do that you should be able to access the InternetMessageHeader collection vai the EmailMessage class https://github.com/OfficeDev/ews-java-api/blob/master/src/main/java/microsoft/exchange/webservices/data/InternetMessageHeader.java

The other way is to use the PR_TRANSPORT_MESSAGE_HEADERS extended property eg

ExtendedPropertyDefinition PR_TRANSPORT_MESSAGE_HEADERS = new ExtendedPropertyDefinition(0x007D, MapiPropertyType.String);
PropertySet psPropSet = new PropertySet(BasePropertySet.FirstClassProperties) { PR_TRANSPORT_MESSAGE_HEADERS};
EmailMessage message = EmailMessage.bind(args.getSubscription().getService(), item.getItemId(),psPropSet);
