Masstransit - Rabbit MQ 虛擬主機

Question

我正在使用公共交通並連接到我的兔子經紀人。

 string uri1 = @"rabbitmq://myusername:mypassword@myip/myvirtualhost/myqueue";

我不斷收到未處理的 ConfigurationException。

服務總線創建過程中拋出異常 {System.Collections.ListDictionaryInternal.NodeKeyValueCollection} {"Failed to start bus services"} at MassTransit.ServiceContainer.Start() in d:\\BuildAgent-03\\work\\aa063b4295dfc097\\src\\MassTransit\\ ServiceContainer.cs：位於 d:\\BuildAgent-03\\work\\aa063b4295dfc097\\src\\MassTransit\\ServiceBus.cs 中 MassTransit.ServiceBus.Start() 的第 83 行：位於 d:\\ BuildAgent-03\\work\\aa063b4295dfc097\\src\\MassTransit\\Configuration\\Builders\\ServiceBusBuilderImpl.cs:line 84 at MassTransit.BusConfigurators.ServiceBusConfiguratorImpl.CreateServiceBus() in d:\\BuildAgent-03\\work\\aa063bsm BusConfigurators\\ServiceBusConfiguratorImpl.cs:line 171 at MassTransit.ServiceBusFactory.New(Action`1 configure) in d:\\BuildAgent-03\\work\\aa063b4295dfc097\\src\\MassTransit\\Configuration\\ServiceBusFactory.cs:line 44

真正奇怪的是，它在沒有指定虛擬主機的情況下工作，但它們偏離了錯誤的虛擬主機。

然后我下載了 rabbitMQ 庫，它使用我的憑據很好地連接到正確的虛擬主機。 這就是我知道我的憑據的方式，虛擬主機設置得很好。 我什至添加了一個隊列以防萬一。 Masstransit 中是否存在一些錯誤？ 我真的不明白我做錯了什么。 我正在考慮不使用大眾運輸並編寫我自己的輕量級版本。

我什至將其復制粘貼到https://github.com/MassTransit/MassTransit/blob/v2.7.2/src/Transports/MassTransit.Transports.RabbitMq/RabbitMqEndpointAddress.cs#L167我的解決方案以檢查它是否正在修剪虛擬主機正確，它是。 我真的很困惑。 ` static readonly Regex regex = new Regex(@"^[A-Za-z0-9- .:]+$");

    public static RabbitMqEndpointAddress Parse(Uri address)
    {
        Guard.AgainstNull(address, "address");

        if (string.Compare("rabbitmq", address.Scheme, true) != 0)
            throw new RabbitMqAddressException("The invalid scheme was specified: " + address.Scheme ?? "(null)");

        var connectionFactory = new ConnectionFactory
        {
            HostName = address.Host,
            UserName = "",
            Password = "",
        };

        if (address.IsDefaultPort)
            connectionFactory.Port = 5672;
        else if (!address.IsDefaultPort)
            connectionFactory.Port = address.Port;

        if (!address.UserInfo.IsEmpty())
        {
            if (address.UserInfo.Contains(":"))
            {
                string[] parts = address.UserInfo.Split(':');
                connectionFactory.UserName = parts[0];
                connectionFactory.Password = parts[1];
            }
            else
                connectionFactory.UserName = address.UserInfo;
        }

        string name = address.AbsolutePath.Substring(1);
        string[] pathSegments = name.Split('/');
        if (pathSegments.Length == 2)
        {
            connectionFactory.VirtualHost = pathSegments[0];
            name = pathSegments[1];
        }

        ushort heartbeat = address.Query.GetValueFromQueryString("heartbeat", connectionFactory.RequestedHeartbeat);
        connectionFactory.RequestedHeartbeat = heartbeat;

       VerifyQueueOrExchangeNameIsLegal(name);

        return new RabbitMqEndpointAddress(address, connectionFactory, name);
    }
    static void VerifyQueueOrExchangeNameIsLegal(string path)
    {
        Match match = _regex.Match(path);

        if (!match.Success)
            throw new RabbitMqAddressException(FormatErrorMsg);
    }

    const string FormatErrorMsg =
      "The path can be empty, or a sequence of these characters: letters, digits, hyphen, underscore, period, or colon.";


    private static void Main(string[] args)
    {

        string uri1 = @"rabbitmq://username:password@mydomain.co.za/vhost/queue";
        IServiceBus serviceBus;

        var result =  Parse(new Uri(uri1));

        serviceBus = ServiceBusFactory.New(sbc =>
        {
            sbc.UseRabbitMq();
            sbc.ReceiveFrom(uri1);
            sbc.Subscribe(c => c.Consumer<SendEmailConsumer>());
        });

        IPublish publishMessage = new MassTransitPublisher(uri1);

        publishMessage.Publish(new SendEmail
            {
                EmailFrom = "*@8.co.za",
                EmailTo = "*@*.co.za",
                Subject = "hello",
                Body = "hello"
            });

        Console.ReadKey();


        JobRunner jobRunner = new JobRunner();

        jobRunner.Start();

        Console.ReadKey();
    }`

任何幫助將不勝感激，或者我可以嘗試使其正常工作。

您使用的是哪個版本的大眾運輸？

我們刪除了從 Uri 聲明用戶名和密碼的功能（因此它不會出現在日志中），您必須通過 API 來完成。

請參閱https://groups.google.com/d/msg/masstransit-discuss/4m5Vf04oRWM/hujvVh1HSdwJ 。

sbc.UseRabbitMq(x => 
                x.ConfigureHost("rabbitmq://yourhost/yourvhost/yourqueue", 
                x=> x.UserName, 
                x.Password))
