404 Invalid SID value in Strophe while using attach()

问题:

I attempted to find an answer to my question with the search engine but i was unable to.

I'm using strophe.muc.js in my backboen project in order to make it real time website. And now i am trying to attach a Session, so that if a page get reloaded, no new connection get created.

function Chat(){   var self = this;   this.connection = false;   this.jid = false;   this.BOSH_SERVICE = 'http://183.155.10.55:7070/http-bind/';    this.init = function () {     self.connection = new Strophe.Connection(this.BOSH_SERVICE);     self.connection.xmlInput = this.log;     self.connection.xmlOutput =  this.log;      if(isObjectNull(sessionStorage.getItem('rid')) && isObjectNull(sessionStorage.getItem('sid')) && isObjectNull(sessionStorage.getItem('jid'))) {         self.connection.connect(             "",             "",             self.events.onConnect);      }else{         self.connection.attach(             sessionStorage.getItem('jid'),             sessionStorage.getItem('sid'),             sessionStorage.getItem('rid'),             self.events.onConnect);     }   };   this.out = function (message) {     $('#log').append('<br />').append(         message     );  };   this.log = function( message ) {     console.log( message );  };   this.events = {     "onConnect": function (status) {         if (status == Strophe.Status.CONNECTING) {          } else if (status == Strophe.Status.CONNFAIL) {          } else if (status == Strophe.Status.DISCONNECTING) {          } else if (status == Strophe.Status.DISCONNECTED) {          } else if (status == Strophe.Status.CONNECTED  || status == Strophe.Status.ATTACHED) {             self.connection.addHandler(function (msg) {                 return self.events.onMessage( msg );             }, null, 'message', null, null, null);               self.connection.send($pres().tree());              self.groupchat.join();         }     },      "onMessage": function( msg ) {         if(jQuery(msg).attr("type") == "chat") {         }         return true;     }   };   this.sendMessage = function( recipient, message ) {     var reply = $msg({to: recipient, type: "chat"})         .c("body")         .t(message);     console.log("SENDING MESSAGE: " + message);     self.connection.send(reply.tree());  };   this.groupchat = {     "_chatRoomId": WebConfig.ChatRoomID,     "_chatRoomNick": function(){         var randomGUID = generateGuid();         return randomGUID;     },     "join":function () {          sessionStorage.setItem("rid",self.connection.rid);         sessionStorage.setItem("sid",self.connection.sid);         sessionStorage.setItem("jid",self.connection.jid);           try {             self.connection.muc.join(                 this._chatRoomId,                 this._chatRoomNick(),                 this.incomingMessageHandler,                 this.groupPresenceHandler,                 null             );          } catch (e) {             console.error(e);         }      },      "message":function (msg) {         try {             self.connection.muc.groupchat(                 this._chatRoomId,                 msg,                 null             );         } catch (e) {             $.error(e);         }     },      "incomingMessageHandler": function ( msg ) {         console.log("MESSAGE HANDLE");          if(jQuery(msg).attr("type") == "chat") {             self.out( "<strong>" + jQuery(msg).attr("from") + ": </strong>" + jQuery(msg).find("body:first").text());         }     },      "groupPresenceHandler": function ( presence ) {         console.log("PRESENCE HANDLE");         console.log(presence);      }  };   this.init();  }; 

Before using attach(), beside connection loses while refreshing page, everything works so well. But after I added attach(), I got an error `POST http://183.155.10.55:7070/http-bind/ 404 (Invalid SID value.)

回答1:

In case anyone has met the same problem as me, I've done it by adjusting my code above a little bit (changing the place off setting the rid, sid, and jid from join() to $(window).unload().

$(window).unload(function() {      sessionStorage.setItem("rid",self.connection.rid);      sessionStorage.setItem("sid",self.connection.sid);      sessionStorage.setItem("jid",self.connection.jid); }); 

No need to increase rid .
