Question

我正在使用我购买的新脚本，并且我一直收到此套接字错误：

GET https://127.0.0.1:8081/socket.io/1/?t=1432947339492 net::ERR_CONNECTION_REFUSED

据我所知，配置文件是正确的。

socket = io.connect( 'https://127.0.0.1:8081' );

和

var socket = require( 'socket.io' );
var express = require( 'express' );
var http = require( 'https' );

var app = express();
var server = http.createServer( app );

var io = socket.listen( server );
io.set('transports',['xhr-polling']);
io.sockets.on( 'connection', function( client ) {
console.log( "New client !" );

client.on( 'message', function( data ) {
    console.log( 'Message received ' + data.name + ":" + data.message );
    //client.broadcast.emit( 'message', { name: data.name, message: data.message } );
    io.sockets.emit( 'message', data);
});

client.on( 'doTrade', function( data ) {
    //console.log( 'Message received ' + data.name + ":" + data.message );
    io.sockets.emit( 'doTrade', data );
});
});

server.listen( 8081 );

我试过这个（我正在使用linux，debian）：

root@Crypto:~# nc 127.0.0.1 8081 < /dev/null; echo $?
(UNKNOWN) [127.0.0.1] 8081 (tproxy) : Connection refused
1
root@Crypto:~# nc 127.0.0.1 80 < /dev/null; echo $?
0

其中0 =开放，1 =关闭。

我猜这可能是连接被拒绝的原因，但我不知道如何解决。

任何人都可以提出解决方案来阻止连接被拒绝。

感谢。

看起来没有什么东西正在侦听端口8081.启动服务器之后，做了什么：

   ALTER PROCEDURE [dbo].[uspApprovalHistory]
        -- Add the parameters for the stored procedure here
                @empID int = null
    AS
    BEGIN
        declare @SRFTable table
        (SRFID nvarchar(50))
        declare @currSRFID nvarchar(50) = null
        -- SET NOCOUNT ON added to prevent extra result sets from
        -- interfering with SELECT statements.
        SET NOCOUNT ON;
        -- Insert statements for procedure here
        insert into @SRFTable
        Select distinct MasterCode from CallForwarding 
        Where EmployeeNo = @empID or ApproverNo = @empID;
        Select *  From callforwarding 
        Where  Mastercode in (select SRFID from @SRFTable)
              and ApproverNo = @empID
              and ForwardDate in (Select max(ForwardDate) from CallForwarding
                              where Mastercode in (select SRFID from @SRFTable)
                              and ApproverNo = @empID)
    END

显示？
