Where,

op = One of GET, PUT, POST, or DELETE

URI Options

The following option parameters must be passed in to the component for HTTPS communications:

Parameter Description
ecomp-client-cert Fully qualified path to the client certificate to use for HTTPS communications.
ecomp-keystore Fully qualified path to the keystore file to use for HTTP communications.
ecomp-keystore-password Obfuscated password for the keystore.

IN Message

Ecomp-Rest Header Parameters

Header Name Description
ecomp-url The fully qualified URL for the HTTP request to be send. This is mandatory.

HTTP Header Parameters

The following parameters, if they are present in the Exchange In Message Headers, will be included as header values in the HTTP request generated by the component:

HTTP Header Name
X-FromAppId
X-TransactionId
resourceVersion
ETag
If-Match
If-None-Match
Accept

Message Body

For HTTP operations that require a content body, the body of the IN message will be used.

OUT Message

Headers

The following header values are populated on the OUT message:

| ecomp-response-code | The response code produced by the HTTP request. | | ecomp-response-message | The response message produced by the HTTP request. |

Message Body

For HTTP operations that produce a content body, the body of the OUT message will be populated with this result.

Example

The following route file illustrates a simple example which takes console input and invokes the rest client, using the input from the console as the content body for the REST request.

<route xmlns="http://camel.apache.org/schema/spring" trace="true">
    <!-- Take some input from the console. -->
    <from uri="stream:in?promptMessage=Enter Something: " />

    <!-- Set the URL that we want to send our REST request to. -->
    <setHeader headerName="ecomp-url">
        <constant>https://localhost:9509/services/search-data-service/v1/search/indexes/gdf/documents/88</constant>
    </setHeader>

    <!-- Set values for some HTTP headers that we want to populate for our reqeust. -->
    <setHeader headerName="X-FromAppId">
        <constant>DataLayer</constant>
    </setHeader>
    <setHeader headerName="X-TransactionId">
        <constant>gdf1</constant>
    </setHeader>

    <!-- Invoke the REST client, using our console input as the content body of our request. -->
    <!-- Note that we provide the paths to the client certificate and keystore, as well as   -->
    <!-- the obfuscated password for the keystore.                                           -->  
    <to uri="rest-client:put?ecompClientCert=c:/dev/dl_microservice/target/swm/package/nix/dist_files/opt/app/ajsc-aai-data-layer-microservice/bundleconfig/etc/auth/aai-client-cert.p12&amp;ecompKeystore=c:/dev/dl_microservice/target/swm/package/nix/dist_files/opt/app/ajsc-aai-data-layer-microservice/bundleconfig/etc/auth/tomcat_keystore&amp;ecompKeystorePassword=70c87528c88dcd9f9c2558d30e817868"/>
