HTTP Connector Reference

Mule Utilities for HTTP Services.

This page serves as a reference for all of the supported attributes and child elements of the HTTP Connector.

Listener

Listener for incoming HTTP requests.

Attributes of listener

Name Description

path

Path to listen for incoming requests.
Type: string
Required: yes
Default: none

allowedMethods

Comma separated list of allowed HTTP methods by this listener. To allow all methods, do not define the attribute.
Type: string
Required: no
Default: none

config-ref

A reference to the configuration element for this listener. If no reference is provided, a default configuration is created.
Type: string
Required: yes
Default: none

responseStreamingMode

Defines if the response should be sent using streaming or not. If this attribute is not present, the behavior depends on the type of the payload (it streams only for InputStream). If set to true, it always streams. If set to false, it never streams. As streaming is done, the response is sent to the user.
Transfer-Encoding: chunked.
Type: enumeration
Required: no
Default: AUTO

parseRequest

By default, the request is parsed (for example, a multi-part request is mapped as a Mule message with null payload and inbound attachments with each part). If this property is set to false, no parsing is done, and the payload always contains the raw contents of the HTTP request.
Type: string
Required: no
Default: none

Child Elements of listener

Name Cardinality Description

response-builder

0..1

Contains the definition of all the parameters that should be sent in the response (headers, status code, response phrase).

error-response-builder

0..1

Contains the definition of all the parameters that should be sent in the response (headers, status code, response phrase).

Listener config

Grouping configuration for a set of listener elements.

Attributes of listener-config

Name Description

name

Identifies the configuration in the registry, so that it can be referenced by the request message processor.
Type: name (no spaces)
Required: yes

protocol

Protocol to use for communication. Valid values are HTTP and HTTPS. Default value is HTTP. When using HTTPS the HTTP communication is going to be secured using TLS or SSL. If HTTPS was configured as protocol, then the user needs to configure at least the keystore in the tls:context child element of this listener-config.
Type: httpProtocol
Required: no
Default: HTTP

host

Host where requests are sent.
Type: string
Required: yes
Default: none

port

Port where the requests are received. If the protocol attribute is HTTP (default) then the default value is 80, if the protocol attribute is HTTPS then the default value is 443. Type: integer
Required: no
Default: none

basePath

Base path to use for all requests that reference this config.
Type: string
Required: no
Default: none

tlsContext-ref

Reference to a TLS config element. This enables HTTPS for this config.
Type: string
Required: no
Default: none

parseRequest

By default, the request is parsed (for example, a multi part request is mapped as a Mule message with null payload and inbound attachments with each part). If this property is set to false, no parsing is done, and the payload always contains the raw contents of the HTTP request.
Type: string
Required: no
Default: none

connectionIdleTimeout

The number of milliseconds that a connection can remain idle before it is closed. The value of this attribute is only used when persistent connections are enabled. Type: integer
Required: no
Default: 30000

usePersistentConnections
