Passing URI to RabbitMQ

Question

I am connecting to RabbitMQ using below code

factory.UserName = "userid";
factory.Password = "mypass@25";
factory.VirtualHost = "/filestream";
factory.Port = AmqpTcpEndpoint.UseDefaultPort;
factory.HostName = "myrabbitserver";
return factory.CreateConnection();

I wanted to change connection settings to the below format:

amqp://userid:mypass@25@myrabbitserver:5672/filestream

My password has @ character due to which I'm not able to pass URI

var factory = new ConnectionFactory();
factory.Uri = "amqp://userid:mypass@25@myrabbitserver:5672/filestream";

I end up supplying each attribute of factory manually. Is there a way that we can tell RabbitMQ that my password has @ by doing something like below?

factory.Uri = "amqp://userid:"mypass@25"@myrabbitserver:5672/filestream";

If I try to change @ in the password to %40, it throws an error when acquiring the connection

None of the specified endpoints were reachable

Solution 1

Apparently, there is no way to encode or escape the @ character in password. I changed password for the user to avoid this character and everything worked as expected.

Solution 2

you can try this:-

 string rabbitmqconnection = $"amqp://{HttpUtility.UrlEncode("username")}: 
 {HttpUtility.UrlEncode("password")}@{"hostname"}
 /{HttpUtility.UrlEncode("/vhost")}";

hope this will resolve your problem.

Solution 3

You need to URLEncode to the symbol @ in the password.

According to your situation, you can try this uri:

amqp://userid:mypass%4025@myrabbitserver:5672/filestream

i'm trying from App.config only; I pasted here for easy reference for others; your syntax ins config is still using @server/vhost; do you mean I remove /vhost?

[jhilden]

a vhost (virtual host) is a concept in rabbit to separate different queues for different users. If you don't need it, you can omit it. Also, my code works great from both web.config or app.config

[techspider]

do you have @ symbol in your password?

[jhilden]

no, the @ symbol is the separator between the password and the name of the server

[techspider]

yes, I have @ in my password too; that's causing the confusion for RabbitMQ

What do you mean by "why"?
