<# .Synopsis Adds binding between RabbitMQ exchange and exchange. .DESCRIPTION The Add-RabbitMQExchangeBinding binds RabbitMQ exchange with exchange using RoutingKey To add ExchangeBinding to remote server you need to provide -HostName. The cmdlet is using REST Api provided by RabbitMQ Management Plugin. For more information go to: https://www.rabbitmq.com/management.html To support requests using default virtual host (/), the cmdlet will temporarily disable UnEscapeDotsAndSlashes flag on UriParser. For more information check get-help about_UnEsapingDotsAndSlashes. .EXAMPLE Add-RabbitMQExchangeBinding -VirtualHost vh1 -ExchangeName e1 -Name e2 -RoutingKey 'e1-e2' This command binds exchange "e1" with exchange "e2" using routing key "e1-e2". The operation is performed on local server in virtual host vh1. .EXAMPLE Add-RabbitMQExchangeBinding -VirtualHost '/' -ExchangeName e1 -Name e2 -RoutingKey 'e1-e2' -BaseUri 127.0.0.1 This command binds exchange "e1" with exchange "e2" using routing key "e1-e2". The operation is performed on server 127.0.0.1 in default virtual host (/). .EXAMPLE Add-RabbitMQExchangeBinding -VirtualHost '/' -ExchangeName e1 -Name e2 -Headers @{FirstHeaderKey='FirstHeaderValue'; SecondHeaderKey='SecondHeaderValue'} -BaseUri 127.0.0.1 This command binds exchange "e1" with exchange "e2" using the headers argument @{FirstHeaderKey='FirstHeaderValue'; SecondHeaderKey='SecondHeaderValue'}. The operation is performed on server 127.0.0.1 in default virtual host (/). .EXAMPLE Add-RabbitMQExchangeBinding -VirtualHost '/' -DontEscape -ExchangeName e1 -Name e2 -Headers @{rjms_erlang_selector="{'=',{'ident',<<"HeadersPropertyName">>},<<"PropertyValue">>}."} -BaseUri 127.0.0.1 This command binds exchange "e1" with exchange "e2" using the headers argument @{rjms_erlang_selector="{'=',{'ident',<<"HeadersPropertyName">>},<<"PropertyValue">>}."}. The operation is performed on server 127.0.0.1 in default virtual host (/). The DontEscape option is required for X-JMS-TOPIC exchanges. The above example will filter for messages which have a header key HeadersPropertyName="PropertyValue". .INPUTS .LINK https://www.rabbitmq.com/management.html - information about RabbitMQ management plugin. #> function Add-RabbitMQExchangeBinding { [CmdletBinding(DefaultParameterSetName='RoutingKey', SupportsShouldProcess=$true, ConfirmImpact="Low")] Param ( # Name of the virtual host.
