I need to pass hash map object to Http outbound using post method in mule.
How can it be done?
Hope this can help
<flow name="demoFlow1" doc:name="demoFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" path="hi" doc:name="HTTP"/>

<scripting:text><![CDATA[
Map<String, Object> map = new HashMap<String, Object>();
map.put("name", "Eddu");
map.put("lastname", "Melendez");
return map;
]]></scripting:text>
</scripting:script>
</scripting:component>

</flow>
This will be the output if you send a map through the service:
INFO 2015-01-22 08:30:42,298 [[demo].connector.http.mule.default.receiver.03] org.mule.api.processor.LoggerMessageProcessor: name=Eddu&lastname=Melendez
You can also add the line below, in order to get a json instead query params in http
As you can see the response will be different
INFO 2015-01-22 08:32:31,014 [[demo].connector.http.mule.default.receiver.03] org.mule.api.processor.LoggerMessageProcessor: {"name":"Eddu","lastname":"Melendez"}

I have the simple flows as following. When we hit one flow, it hits another flow and gets http.status 302 and Location , which means it must redirect to the location in Location header. But it is throwing exception.
<flow name="httpconnectorFlowRedirection">

I am getting this error only when follow redirects set to true on outbound endpoint
I am using mule 3.5.
I got the answer. I need to use GET reqeust for successful redirection.
But if I use http listeners(since mule 3.6), I am able to redirect even for POST requests. Consider the following example.
<http:listener-config name="GlobalHTTPConnector" host="localhost" port="9876" doc:name="HTTP Listener Configuration" basePath="mulelearning"/>
<flow name="redirection-flow">
<http:listener config-ref="GlobalHTTPConnector" path="/requestredir" doc:name="HTTP"/>
<!--
When followRedirects is set to true, when http.status from called service is redirection(eg:301), it redirects to new location.
In this case /redFlow1 sends a redirection code 301 and location header. Hence it redirects to /redFlow2 (see the flows below) and gives us the response 'payload from red-flow2'
-->
<http:request config-ref="HTTP_Request_Configuration" path="/redFlow1" method="POST" followRedirects="true" doc:name="HTTP" />
</flow>
<flow name="red-ser1">
<http:listener config-ref="GlobalHTTPConnector" path="/redFlow1" doc:name="HTTP"/>

I have a Mule flow which uses HTTP Request endpoint in Mule CE3.6.1. It needs to use encoded HTTP url to get the correct data.
Please note the encoded url: /items?q=%2Blabel%3ABOTV2309H*%20%2Bparent.uri%3A%5C%2Fbristol%5C%2Ftest%5C%2Fgateway%5C%2F*&rows=100&start=0
Here is the test flow.
<?xml version="1.0" encoding="UTF-8"?>

</flow>
</mule>
When the Mule flow runs, here is the url being requested (Found through wireshark):
/items?q=%20label%3ABOTV2309H%2A%20%20parent.uri%3A%5C%2Fbristol%5C%2Ftest%5C%2Fgateway%5C%2F%2A&rows=100&start=0
Please note %2B is replaced with %20 in two places, which obviously do not return the data I need.
Is this an issue with HTTP endpoint?
Thanks!
I divided the params into query and uri params. Then this issue got resolved.
<http:request config-ref="HTTP_Request_Config_Search" path="/items" method="GET" doc:name="HTTP">
<http:request-builder>
<http:query-param paramName="q" value="+label:BOTV2309H* +parent.uri:\/test\/gateway\/*"/>
<http:uri-param paramName="rows" value="100"/>
<http:uri-param paramName="start" value="0"/>
</http:request-builder>

I'm new in Mule ESB and trying to send a post request to a REST Service. The body of the request is in String form and the request should be x-www-form-urlencoded. I set the payload to my parameters and send the request to the REST Service but I get an exception:
Failed to invoke REST service "http://username:password#192.168.10.252/api/rest/session/login.json". Message payload is of type: String
My Rest URL is: (#[restURL]) ${dms.host}/api/rest/session/login.json
My parameter is (set as payload #[restBody]): username=user&password=pass

Can somebody help me figure this out please?
Thanks a lot in advance.
Note: Updated according to David's reply.
-------------------UPDATE--------------------
So now, for testing purposes, I have modified the flow like this:
<set-payload value="#[restBody]" doc:name="Set Payload"/>
<custom-transformer class="de.mfg.osii.http.StringToURIParametersMapTransformer" doc:name="String To URI Parameters"/>
<http:rest-service-component httpMethod="POST" serviceUrl="http://${dms.user}:${dms.pass}##[restURL]">
<http:requiredParameter key="username" value="#[payload.get('username')]" />
<http:requiredParameter key="password" value="#[payload.get('password')]" />
</http:rest-service-component>
So now the payload is: {username=user, password=pass}
But now when I try to run this, I get the following error:
1. Failed to invoke REST service "http://user:pass#192.168.10.252/api/rest/session/login.json". Message payload is of type: LinkedHashMap (org.mule.transport.http.components.RestServiceException)
Update: The above problem, the exception, has just been solved by adding a message-property "Content-Type" with the value "application/x-www-form-urlencoded".
Still the last part, below, remains a mystery for me :)
The other thing is, as I stated in the comment to David's answer, can I add the required parameters for the rest component in an adaptive way? To be more clearer, I do not want to create different flows for every different request. I have the parameter map in the payload, so I want to iterate over them and put them in the required parameters. Is something like this possible?
Thanks a lot in advance!
-------------------UPDATE--------------------
So, I've modified my flow and used David's suggestions. However, now, I'm getting an HTTP 405 error (Method not allowed). But I'm sure I'm posting to the correct address with correct content-type. What is the reason for this? Does anybody have an idea?
My payload coming into this flow is a string (url encoded parameters) such as ->

Here is how you pass parameters to be URL encoded with the rest-service-component:

<http:requiredParameter key="username" value="user" />

I want to test if an http request like http://localhost:8088/esb/?type=xxxx&id=1234 if it contains the String xxxx in a way to route the request to the desired web service proxy.
I've tried withe the expression expression="#[string.contains['xxxxx']]" but it does not seem to work.
any idea?
thank you.
Two things: You will need to replace "string" with the property you want to execute on. Either a message property or payload etc. i.e #[payload.contains...].
"contains" is a Java method on java.lang.String so you need to use standard Java method invocation with () instead of [].
Working example:
<choice doc:name="Choice">
<when expression="#[payload.contains('xxxx')]">
<logger level="ERROR" message="YES" />
</when>
<otherwise>
<logger level="ERROR" message="NO" />
</otherwise>
</choice>
Or directly work off inbound properties for your query params:
After your http inbound use set-variable to store your query params into flow variables.
And then use the flow variales in your expression.
<set-variable value="#[message.inboundProperties['id']]" variableName="paramId"></set-variable>
<set-variable value="#[message.inboundProperties['type']]" variableName="paramType"></set-variable>
or you can directly use inbound property for comparision.
<when expression="#[message.inboundProperties['type']== 'XXXX']">
When I run my flow, I get the following error `
<org.apache.cxf.staxutils.DepthXMLStreamReader>
<reader class="org.mule.module.cxf.support.StreamClosingInterceptor$1">
<reader class="com.ctc.wstx.sr.ValidatingStreamReader">

we can see the correct soap response starting from the <mInputBuffer>, is there a way to get only the soap response??

thank you.
This expression #[payload.contains('c22')] can't work because the payload is an InputStream. Aren't you seeing stack traces in Mule's logs?
In any case, try adding <object-to-string-transformer /> before the choice and see if it fixes the issue.
EDIT:
The problem is that you're using XStream (in xm:object-to-xml-transformer) to serialize the CXF response object (org.apache.cxf.staxutils.DepthXMLStreamReader) into XML. The CXF response should not be messed with and should be handled by the cxf:proxy-client in the response phase of the flow. The xm:object-to-xml-transformer and file:outbound-endpoint after the choice router are probably disturbing this mechanism. Try to wrap them in a response element above the choice router to they execute after it in the response phase.
Note that I have already given you this advice in your other question https://stackoverflow.com/a/16615537/387927 but you did not react to it.
Also I don't think byte-array-to-string-transformer does anything: the message payload after the http:outbound-endpoints should be org.apache.cxf.staxutils.DepthXMLStreamReader, preventing this transformer to fire.
