Java calls Google Analytics API for website statistics

The following code is a piece of code that I modified and commented out according to the official Google Documents to collect statistics on access traffic and other information.
[Java]
Package cn.edu. KFC. bean;
Import com. google. gdata. client. analytics. AnalyticsService;
Import com. google. gdata. client. analytics. DataQuery;
Import com. google. gdata. data. analytics. AccountEntry;
Import com. google. gdata. data. analytics. AccountFeed;
Import com. google. gdata. data. analytics. DataEntry;
Import com. google. gdata. data. analytics. DataFeed;
Import com. google. gdata. util. AuthenticationException;
Import com. google. gdata. util. ServiceException;
Import java. io. IOException;
Import java.net. MalformedURLException;
Import java.net. URL;
Public class GoogleAnalytics {
// Use the ClientLogin method to access Google Analytics. The two constants store the user name and password respectively.
Private static final String CLIENT_USERNAME = "anyone@gmail.com"; // Google account
Private static final String CLIENT_PASS = "1234567"; // Google Password
Private static final String TABLE_ID = "ga: 715123"; // The table id of the Google Analytics configuration file that this account has the right to access
 
Public void myTest (){
Try {
/*
* The system creates a service object. A service object parameter is a string that represents the application name. Then, the system will use the setUserCredentials method for processing.
* Google Analytics (analysis) authorization.
*/
// Service Object to work with the Google Analytics Data Export API.
AnalyticsService analyticsService = new AnalyticsService ("gaExportAPI_acctSample_v2.0 ");
// Client Login Authorization.
AnalyticsService. setUserCredentials (CLIENT_USERNAME, CLIENT_PASS );
 
// Get data from the Account Feed.
GetAccountFeed (analyticsService); // get account information
 
// Access the Data Feed if the Table Id has been set.
If (! TABLE_ID.isEmpty ()){
// Get profile data from the Data Feed.
GetDataFeed (analyticsService); // obtain data information (including "metrics" and "dimensions ")
}
} Catch (AuthenticationException e ){
System. err. println ("Authentication failed:" + e. getMessage ());
Return;
} Catch (IOException e ){
System. err. println ("Network error trying to retrieve feed :"
+ E. getMessage ());
Return;
} Catch (ServiceException e ){
System. err. println ("Analytics API responded with an error message :"
+ E. getMessage ());
Return;
}
}
/**

Private static void getAccountFeed (AnalyticsService analyticsService)
Throws IOException, MalformedURLException, ServiceException {
// Construct query from a string.
URL queryUrl = new URL ("https://www.google.com/analytics/feeds/accounts/default? Max-results = 50 ");
// Make request to the API.
AccountFeed accountFeed = analyticsService. getFeed (queryUrl, AccountFeed. class );
// Output the data to the screen.
System. out. println ("-------- Account Feed Results --------");
For (AccountEntry entry: accountFeed. getEntries ()){
System. out. println ("\ nAccount Name ="

+ "\ NProfile Id =" + entry. getProperty ("ga: profileId") // configuration file Id
+ "\ NTable Id =" + entry. getTableId (). getValue (); // The Table Id of the configuration file
}
}
/**

*/
Private static void getDataFeed (AnalyticsService analyticsService)
Throws IOException, MalformedURLException, ServiceException {
 
// Create a query using the DataQuery Object.
DataQuery query = new DataQuery (new URL ("https://www.google.com/analytics/feeds/data "));
Query. setStartDate ("2011-10-01"); // start time of the data to be counted
Query. setEndDate ("2011-10-30"); // end time of the data to be counted
Query. setDimensions ("ga: pageTitle, ga: pagePath"); // dimension information to be counted
Query. setMetrics ("ga: pageviews, ga: bounces, ga: visits, ga: visitors"); // metrics to be measured
Query. setSort ("-ga: pageviews ");
Query. setMaxResults (10 );
Query. setIds (TABLE_ID );
 
// Make a request to the API.
DataFeed dataFeed = analyticsService. getFeed (query. getUrl (),
DataFeed. class );
 
// Output data to the screen.
System. out. println ("----------- Data Feed Results ----------");
For (DataEntry entry: dataFeed. getEntries ()){
System. out. println ("\ nPage Title ="
+ Entry. stringValueOf ("ga: pageTitle") + "\ nPage Path ="
+ Entry. stringValueOf ("ga: pagePath") + "\ nPageviews ="
+ Entry. stringValueOf ("ga: pageviews") + "\ nga: bounces ="
+ Entry. stringValueOf ("ga: bounces") + "\ nga: visits access COUNT ="
+ Entry. stringValueOf ("ga: visits") + "\ nga: Number of visitors ="
+ Entry. stringValueOf ("ga: visitors "));
}
}
 
}
Finally, call the myTest () method of this class in any way (main () or servlet.
Note:
Add "ga:" before the number of Table ID, for example, ga: 47778978
The dimensions and metrics to be obtained must be set in query. setDimensions () and query. setMetrics (). See the preceding example.
