How to upload multiple files via REST over HTTP using Mule?

Question

I have a folder say "MyFiles" where I have lots of files. Now I need to upload those file via REST over HTTP . What will be the approach?

I tried the below but it is wrong

<flow name="testFlow1" doc:name="testFlow1">
        <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>


         <http:rest-service-component 
                                serviceUrl="http://localhost:8280/rest/xyz" 
                                httpMethod="POST"> 
         </http:rest-service-component> 

    <http:endpoint host="localhost" port="5430" encoding="UTF-8" 
                method="POST" connector-ref="fileHttp" path="fileuploader" name="muleFileUploader">
       </http:endpoint>

</flow>

Please help. Since the input folder will have multiple files, how can we achieve that also?

Thanks

Your flow doesn't use a file inbound endpoint and uses a generic (non-in non-out) HTTP endpoint so there's no way this can work.

Below is a configuration that successfully uploads files to an HTTP endpoint. I can not make it work without the object-to-byte-array-transformer (the same file gets polled over and over again - bug?), so I hope your files are not huge...

<flow name="fileUploader">
    <file:inbound-endpoint path="/tmp/mule/in"
        pollingFrequency="5000" moveToDirectory="/tmp/mule/done" />
    <object-to-byte-array-transformer />
    <http:outbound-endpoint address="http://..."
        method="POST" exchange-pattern="request-response" />
</flow>
