Ext Direct related classes are basically located in the Ext.direct package. In addition, there are also Direct type data codes.Ext.data.proxy.Direct

In these classes, there are mainly the following concepts:

• Provider data provider
• Event , event, event is created after some interaction with the server. It is essentially just a data structure used to save Direct responses.
• Manager: Direct's manager

• Ext.direct.JsonProvider: for simple JSON operations
• Ext.direct.PollingProvider: Duplicate request
• 
  Ext.direct.RemotingProvider: The result of the server-side Provider class exposed to the client is as follows:
