A factory method for Transport objects.
This method will construct a Transport object from transport configuration gleaned from the user’s configuration and, optionally, a transport URL.
If a transport URL is supplied as a parameter, any transport configuration contained in it takes precedence. If no transport URL is supplied, but there is a transport URL supplied in the user’s configuration then that URL will take the place of the URL parameter. In both cases, any configuration not supplied in the transport URL may be taken from individual configuration parameters in the user’s configuration.
An example transport URL might be:
rabbit://me:passwd@host:5672/virtual_host
and can either be passed as a string or a TransportURL object.
Parameters: |
---|
A messaging transport.
This is a mostly opaque handle for an underlying messaging transport driver.
It has a single ‘conf’ property which is the cfg.ConfigOpts instance used to construct the transport object.
A parsed transport URL.
Transport URLs take the form:
transport://user:pass@host1:port[,hostN:portN]/virtual_host
i.e. the scheme selects the transport driver, you may include multiple hosts in netloc and the path part is a “virtual host” partition path.
Parameters: |
---|
Parse an url.
Assuming a URL takes the form of:
transport://user:pass@host1:port[,hostN:portN]/virtual_host
then parse the URL and return a TransportURL object.
Netloc is parsed following the sequence bellow:
It is first split by ‘,’ in order to support multiple hosts
The last parsed username and password will be propagated to the rest of hosts specified:
user:passwd@host1:port1,host2:port2
{“username”: “user”, “password”: “passwd”, “host”: “host1:port1”}, {“username”: “user”, “password”: “passwd”, “host”: “host2:port2”}
]
In order to avoid the above propagation, it is possible to alter the order in which the hosts are specified or specify a set of fake credentials using ”,:@host2:port2”
user:passwd@host1:port1,:@host2:port2
{“username”: “user”, “password”: “passwd”, “host”: “host1:port1”}, {“username”: “”, “password”: “”, “host”: “host2:port2”}
]

Returns: | A TransportURL |
A host element of a parsed transport URL.
