Gmail使用Atom格式提供了邮件的摘要信息，你可以通过一些聚集器来查看你邮箱中的邮件，你也可以自己编写程序来读取这些邮件信息，不说废话了，下面是如何编写Java程序来透过RSS访问gmail的邮件信息：
|
/**
* @param args
* @throws IOException
* @throws HttpException
*/
public static void main(String[] args) throws Exception {
HttpClient client = new HttpClient();
client.getState().setCredentials(null,null,
new UsernamePasswordCredentials("xxxxx@gmail.com", "邮箱密码")
);
GetMethod get = new GetMethod("https://gmail.google.com/gmail/feed/atom");
get.setDoAuthentication(true);
try {
client.executeMethod(get);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(get.getResponseBodyAsStream());
Element elem = doc.getDocumentElement();
NodeList mails = elem.getElementsByTagName("entry");
for(int i=0;i<mails.getLength();i++){
Element item = (Element)mails.item(i);
String id = item.getElementsByTagName("id").item(0).getFirstChild().getNodeValue();
System.out.println("ID:"+id);
String title = item.getElementsByTagName("title").item(0).getFirstChild().getNodeValue();
System.out.println("TITLE:"+title);
String summary = item.getElementsByTagName("summary").item(0).getFirstChild().getNodeValue();
System.out.println("SUMMARY:"+summary);
System.out.println("---------------------------------");
}
} finally {
get.releaseConnection();
}
}

OK. 换上你自己的邮箱和密码运行一下就搞定了。
心情: 一般
