processWebhookNotification

public static void processWebhookNotification(javax.servlet.http.HttpServletRequest req,
                                              javax.servlet.http.HttpServletResponse resp,
                                              DataStoreFactory dataStoreFactory)
                                       throws javax.servlet.ServletException,
                                              IOException

Utility method to process the webhook notification from HttpServlet.doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) by finding the notification channel in the given data store factory.

It is a wrapper around processWebhookNotification(HttpServletRequest, HttpServletResponse, DataStore) that uses the data store from StoredChannel.getDefaultDataStore(DataStoreFactory).

Parameters:

req - an HttpServletRequest object that contains the request the client has made of the servlet

resp - an HttpServletResponse object that contains the response the servlet sends to the client

dataStoreFactory - data store factory

Throws:

IOException - if an input or output error is detected when the servlet handles the request

javax.servlet.ServletException - if the request for the POST could not be handled

processWebhookNotification

public static void processWebhookNotification(javax.servlet.http.HttpServletRequest req,
                                              javax.servlet.http.HttpServletResponse resp,
                                              DataStore<StoredChannel> channelDataStore)
                                       throws javax.servlet.ServletException,
                                              IOException

Utility method to process the webhook notification from HttpServlet.doPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse).

The ServletRequest.getInputStream() is closed in a finally block inside this method. If it is not detected to be a webhook notification, an HttpServletResponse.SC_BAD_REQUEST error will be displayed. If the notification channel is found in the given notification channel data store, it will call UnparsedNotificationCallback.onNotification(com.google.api.client.googleapis.notifications.StoredChannel, com.google.api.client.googleapis.notifications.UnparsedNotification) for the registered notification callback method.

Parameters:

req - an HttpServletRequest object that contains the request the client has made of the servlet

resp - an HttpServletResponse object that contains the response the servlet sends to the client

channelDataStore - notification channel data store

Throws:

IOException - if an input or output error is detected when the servlet handles the request

javax.servlet.ServletException - if the request for the POST could not be handled
