Instant Messaging (RPC) rtmp Implementation--code implementation Chapter

The general steps to implement are:

Step 1: Define Netconnection objects to connect rtmp and listen for netstatusevent.net_status events

Step 2: Judge event.info.code== "NetConnection.Connect.Success" in the Netstatusevent.net_status event, through Sharedobject.getromote () Get Sharedobject Object

Step 3: Listen for the Syncevent.sync event of the Sharedobject object and Sharedobj.connect (netconnection)

Step 4: This time you can use Sharedobj.send () to send a message to the server, and then the server broadcasts the login message to all the clients that are currently connected

Step 5: You can get the data from Sharedobj.data in the Syncevent.sync event.

Step 6: Define a function that gets the return value after the server is called, which needs to be declared public

Ps:

Server side and client, both are in Operation Sharedobject object, client is read, server side is write (only server performs write to ensure data is correct)

Server-side Send message to each client, divided into client request and server-side request implementation

* Client requests are typically called sharedobj.send ("Getserverdata", "message") to implement

* Server-side is called Netconnection.call ("background method", NULL, "message"), then the background method is defined via Souser.sendmessage ("Getserverdata", New object[]{" Message "}) to send messages

Server-side code (. NET):

ToString (); Isharedobject Souser = This. Getsharedobject (connection. Scope,"Onlineuserlist"); if (Souser = = null) { This. Createsharedobject (connection. Scope,"Onlineuserlist",false); Souser = This. Getsharedobject (connection.

Client.setattribute ("Currentname", name);return true; } Publicoverride void Appdisconnect (Iconnection connection) {string name = connection. Client.getattribute ("Currentname").            ToString (); Isharedobject Souser = This. Getsharedobject (connection. Scope,"Onlineuserlist");            if (souser! = null) {Souser.removeattribute (name); } souser.sendmessage ("Getserverdata",NewObject[] {name +"Disconnected"}); Base.        Appdisconnect (connection); }//Using a common method of sending messages on the server side, the client needs to call the method via Netconnection.call ()           Publicvoid SendMessage (iconnection connection, String msg) {string userName = connection. Client.getattribute ("Currentname") asString Isharedobject Souser = Getsharedobject (connection. Scope,"Onlineuserlist"); Souser.sendmessage ("Getserverdata",NewObject[] {msg}); }    }}
