HTTP Connector XML Reference

Anypoint Connector for HTTP (HTTP Connector) listens for events or performs operations based on the HTTP or HTTPS protocol. When using the HTTPS protocol, the connector requires a TLS context child element configuration. The following examples show HTTP Connector source and operations configuration in XML.

HTTP Listener XML Configuration Example

The http:listener-config parent element organizes connection elements, such as the listen port and tls:context, inside a child http:listener-connection element. The following example shows the XML configuration:

<http:listener-config name="lisConfig" basePath="api">
  <http:listener-connection protocol="https" port="${serverPort}" host="localhost" usePersistentConnections="true">
    <tls:context>
      <tls:key-store path="keystore.jks" keyPassword="key" password="pass"/>
    </tls:context>
  </http:listener-connection>
</http:listener-config>

The following example shows the XML configuration of an http:listener source in a flow:

<flow name="server">
  <http:listener path="test" allowedMethods="GET" config-ref="lisConfig"/>
  <logger message="HEY"/>
</flow>

To access HTTP listener attributes, use DataWeave syntax as shown in the following table:

HTTP object Mule runtime engine 4.x

HTTP object	Mule runtime engine 4.x
Method	`#[attributes.method]`
Path	`#[attributes.listenerPath]`
Relative Path	`#[attributes.relativePath]`
Request URI	`#[attributes.requestUri]`
Query String	`#[attributes.queryString]`
Query Parameters	`#[attributes.queryParams]`
URI Parameters	`#[attributes.uriParams]`
Version	`#[attributes.version]`
Scheme	`#[attributes.scheme]`
Headers	`#[attributes.headers]`
Remote Address	`#[attributes.remoteAddress]`
Client Certificate	`#[attributes.clientCertificate]`

HTTP Request XML Configuration Example

The http:request-config parent element organizes connection elements of the request inside a child http:request-connection element. The following example shows the XML configuration:

<http:request-config name="reqConfig" basePath="api/v2">
  <http:request-connection protocol="HTTP" port="${clientPort}" host="localhost">
    <tls:context>
      <tls:trust-store path="ssltest-cacerts.jks" password="changeit"/>
    </tls:context>
    <http:authentication>
      <http:basic-authentication username="#[user]" password="#[password]" preemptive="#[preemptive]" />
    </http:authentication>
  </http:request-connection>
</http:requester-config>

The following example shows the XML configuration of an http:request operation in a flow:

<flow name="client">
   <http:request path="/" config-ref="reqConfig"/>
</flow>

The HTTP request returns HttpResponseAttributes. To access HTTP request attributes, use DataWeave syntax as shown in the following table:

HTTP object Mule runtime engine 4.x

HTTP object	Mule runtime engine 4.x
Status Code	`#[attributes.statusCode]`
Reason Phrase	`#[attributes.reasonPhrase]`
Headers	`#[attributes.headers]`

Status Code

#[attributes.statusCode]

Reason Phrase

#[attributes.reasonPhrase]

Headers

#[attributes.headers]

HTTP Load Static Resource XML Configuration Example

The following example shows the XML configuration of an http:load-static-resource operation in a flow:

<flow name="server">
   <http:listener path="test" allowedMethods="GET" config-ref="lisConfig"/>
   <http:load-static-resource resourceBasePath="root" defaultFile="index.html"/>
</flow>

HTTP Basic Security Filter XML Configuration Example

The following example shows the XML configuration of an http:basic-security-filter operation in a flow:

<flow name="listenerBasicAuth">
   <http:listener config-ref="listenerConfigBasicAuth" path="/basic"/>
   <http:basic-security-filter realm="mule-realm"/>
   <logger message="TestBasicAuthOk"/>
</flow>

HTTP Request, Response, and Error Response Body XML Example

Defining the body of an HTTP request, response, and error response is optional. When you do not explicitly define the body element, the request or response returns the default payload.

The following example shows the XML configuration of an http:request operation that defines a custom body, a key/value query-parameter, an X-Custom header, and a uri-params with the uriParamsMap variable that populates the URI parameter uriParam:

<http:request path="/{uriParam}/test"  config-ref="reqConfig">
   <http:body>
       #['Custom body']
   </http:body>
   <http:headers>
       #[{'X-Custom' : 'custom'}]
   </http:headers>
   <http:uri-params>
       #[uriParamsMap]
   </http:uri-params>
   <http:query-params>
       #[{'key’' : 'value’'}]
   </http:query-params>
</http:request>

The following example shows the XML configuration of an http:listener source that lacks a defined body element. The returned value is the default payload. The payload defines an http:response to a successful execution that consists of a 200 statusCode and Ok as the reasonPhrase, with headers Name as content, and Something as someValue:

<http:listener path="test" allowedMethods="GET" config-ref="lisConfig">
   <http:response statusCode="200" reasonPhrase="Ok">
       <http:headers>
           #[{"Name" : "content", "Something" : someValue}]
       </http:headers>
   </http:response>
</http:listener>

The following example shows the XML configuration of an http:listener source that defines a response to an execution failure that returns a 502 statusCode and Failure as the reasonPhrase, with headers Error as FIRE and body as Oops, something is wrong:

<http:listener path="test" allowedMethods="GET" config-ref="lisConfig">
   <http:error-response statusCode="502" reasonPhrase="Failure">
       <http:body>
           #[‘Oops, something is wrong’]
       </http:body>
       <http:headers>
           #[{"Error" : "FIRE"}]
       </http:headers>
   </http:error-response>
</http:listener>
