我正在使用下面的代码来获取我的渠道洞察数据的链接。不知何故,我的代码将 null 作为链接返回。
/ *代码* ** /
public static final String FEED_URL = "http://gdata.youtube.com/feeds/api/users/mychannelname/uploads"; //i put my channel's name in 'mychannelname'
String username = "mygmailid"; //here i entered my gmail id eg. mikeme@gmail.com
String password = "mypassword";
String developerKey = "AI39si7ffVeKWbG1k37***********************************************" //developer key
YouTubeService service = new YouTubeService( username ,developerKey); //just put username instead of clientid since client id no longer available
try {
service.setUserCredentials(username, password);
} catch (AuthenticationException e) {
System.out.println("Invalid login credentials.");
System.exit(1);
}
Query query = null;
try {
query = new Query(new URL( FEED_URL));
} catch (MalformedURLException e) {
//TODO Auto-generated catch block
e.printStackTrace();
}
ChannelFeed channelFeed = null;
try {
channelFeed = service.query(query, ChannelFeed.class);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(channelFeed.getEntries() + ":");
System.out.println(" Link : "+channelFeed.getLink("http://gdata.youtube.com/schemas/2007#insight.views", "text/html") + ":");
/ * ** * ****结束* ** * ** * *** /
我在这里链接为空
谁能帮我找出这里出了什么问题?
谢谢,迈克
