Question

我试图从nodejs连接到我们组织中安装的安慰设备。我采用了与solace web messaging demo相同的代码。如以下示例中所示，是session属性：

my_web_server_url = "http://<ip:port>/smf";
my_client_username = "<username>";
my_vpn = "<vpnname>";
my_password = "<password>";

当我调试solace.SessionEventCBInfo的回调方法solace.SolclientFactory.createSession的代码时，我发现以下条件永远不会满足：

if (event.sessionEventCode === solace.SessionEventCode.UP_NOTICE) {
   console.log(":::Connected:::");
}

控件进入所有3种传输方案（HTTP_BASIC，HTTP_BASE64和HTTP_STREAMING）的连接状态，最后进入错误状态。

else if (event.sessionEventCode === solace.SessionEventCode.CONNECTING) {
            console.log(":::Connecting.....");
        } else {
            console.log(":::Error!:::");
        }

Solace设备有任何配置问题吗？是否应该在配置时在Solace设备上启用Web消息传递？或者我在代码中做错了什么？

更新

请在下面找到session活动的详细信息：

Session event: sessionEventCode=CONNECTING, infoStr=Establishing connection (transport:HTTP_BINARY_STREAMING), responseCode=, errorSubCode=, correlationKey=, reason=()
(index):105 Connecting.....
(index):102 Session event: sessionEventCode=CONNECTING, infoStr=Establishing connection (transport:HTTP_BINARY), responseCode=, errorSubCode=, correlationKey=, reason=()
(index):105 Connecting.....
(index):102 Session event: sessionEventCode=CONNECTING, infoStr=Establishing connection (transport:HTTP_BASE64), responseCode=, errorSubCode=, correlationKey=, reason=()
(index):105 Connecting.....
(index):102 Session event: sessionEventCode=DISCONNECTED, infoStr=Session is destroyed, responseCode=, errorSubCode=, correlationKey=, reason=(Transport session event: sessionEventCode=2, infoStr=Session is destroyed, responseCode=, sid=)
(index):109 Error!!!!!

Answer 1

API的断开原因可以为我们提供有关连接失败原因的更多信息。

请您在会话事件回调开始时打印出事件吗？

new solace.SessionEventCBInfo(function(session, event) {
    console.log(event.toString());
    // The rest of your connection logic below
}

我希望看到类似以下内容。

Session event: sessionEventCode=CONNECTING, infoStr=Establishing connection (transport:HTTP_BINARY_STREAMING), responseCode=, errorSubCode=, correlationKey=, reason=()
Session event: sessionEventCode=CONNECTING, infoStr=Establishing connection (transport:HTTP_BINARY), responseCode=, errorSubCode=, correlationKey=, reason=()
Session event: sessionEventCode=CONNECTING, infoStr=Establishing connection (transport:HTTP_BASE64), responseCode=, errorSubCode=, correlationKey=, reason=()
Session event: sessionEventCode=DISCONNECTED, infoStr=Connection create failure: HTTP request failed: status=503 statusText=Error: connect EHOSTUNREACH, responseText length=143, XHR errorCode=EHOSTUNREACH, responseCode=, errorSubCode=44, correlationKey=, reason=(Transport session event: sessionEventCode=2, infoStr=Connection create failure: HTTP request failed: status=503 statusText=Error: connect EHOSTUNREACH, responseText length=143, XHR errorCode=EHOSTUNREACH, responseCode=44, sid=N/A)

在我的示例中，无法从运行nodejs的服务器联系Solace设备。这可以从EHOSTUNREACH错误代码中找出。

请注意，需要在Solace设备上执行以下配置以启用Web消息传递。

需要在设备上安装许可证密钥才能启用Web消息传递。您可以通过CLI中的以下命令对此进行验证。

solace1> show product-key

Product Key : H1mqWPKYjgQ-7JiNX6d2k1M-Tg9Ezd5a7WA-CACHE:WEB:GM450K:OMAMA-C-S009000149
  Unlocked Features : 4
    SolCache
    WEB Transport Service
    Guaranteed Messaging 450k
    OpenMAMA

请注意＆＃34; WEB传输服务＆＃34;是网络消息传递所必需的。

需要启用Web传输服务。

solace1> show service

Msg-Backbone:       Enabled
  SMF:              Enabled
    Web-Transport:  Enabled
  REST Incoming:    Shutdown
  REST Outgoing:    Shutdown

Max Incoming Connections:       9000
  Service SMF:                  9000
  Service Web-Transport:        9000
  Service REST:                 9000
Max Outgoing Connections:
  Service REST:                 6000
Max SSL Connections:            9000

验证用于Web传输的端口。默认值为80，可以通过查看WEB服务通过show service命令进行验证。

安慰消息 - 无法通过nodejs
