Mulesoft HTTP Connector configuration - mule

When I connect to:
http://legacy.cafebonappetit.com/api/2/menus?cafe=261
I get back JSON as I should. However, I'm unable to do this with the Mulesoft HTTP Connector. When I try, I get back 500. Here is my XML:
<flow name="GetDiningInfo">
<http:listener config-ref="HTTP_Listener_Configuration" path="/dining" doc:name="HTTP"/>
<http:request config-ref="HTTP_Request_Configuration" path="/api/2/menus" method="GET" doc:name="GET announcement from dining server" followRedirects="true" host="legacy.cafebonappetit.com" port="80">
<http:request-builder>
<http:query-param paramName="cafe" value="261"/>
</http:request-builder>
</http:request>
<logger level="INFO" doc:name="Logger"/>
</flow>
The connector global config is:
<http:request-config name="HTTPReqConfigforCafeBonAppetit.com" host="legacy.cafebonappetit.com" port="80" basePath="/api/2" doc:name="HTTP Request Configuration"/>
What am I doing wrong?
Thanks...
UPDATE: Still no joy. I'm still getting back a 500 internal server failure through Mule.
Here is the latest code that does not duplicate the path:
<http:request-config name="HTTPReqConfigforCafeBonAppetit" host="legacy.cafebonappetit.com" port="80" basePath="/api/2/" doc:name="HTTP Request Configuration" usePersistentConnections="false"/>
<flow name="GetDiningInfo">
<http:listener config-ref="HTTP_Listener_Configuration" path="/dining" doc:name="HTTP"/>
<http:request config-ref="HTTPReqConfigforCafeBonAppetit" path="menus" method="GET" doc:name="GET menu" followRedirects="true" parseResponse="false">
<http:request-builder>
<http:query-param paramName="cafe" value="261"/>
</http:request-builder>
</http:request>
<logger level="INFO" doc:name="Logger"/>
</flow>

Have you evaluated the URL request result? By referring that configuration it should be http://legacy.cafebonappetit.com/api/2/api/2/menus?cafe=261
That's why you unable to get the expected result. Therefore replace the path of http:request with /menus, without the base path /api/2. Because it's already defined in http:request-config

The server for legacy.cafebonappetit.com cannot handle the header Host including the port (which is valid). The HTTP connector sends Host: legacy.cafebonappetit.com:80 by default causing the server to reject the request, so you need to explicitly add the Host header, as in the example below.
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>
<http:request-config name="HTTP_Request_Configuration" host="legacy.cafebonappetit.com" port="80" basePath="/api/2" doc:name="HTTP Request Configuration"/>
<flow name="so-testFlow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/dining" doc:name="HTTP"/>
<http:request config-ref="HTTP_Request_Configuration" path="menus" method="GET" doc:name="HTTP">
<http:request-builder>
<http:query-param paramName="cafe" value="261"/>
<http:header headerName="Host" value="legacy.cafebonappetit.com"/>
</http:request-builder>
<http:success-status-code-validator values="100..599"/>
</http:request>
</flow>
The example also includes a status code validator for all codes which allows you to see the exact error the server sends when the explicit Host header is removed.

Well the trouble here is when you send a request to the server by the 80 port. The server rejects the request immediately. To resolve this you got to add the header, so this way the server understand and process the request.
To do that just add the following line: $<http:header headerName="Host" value="the_host"/>.
The following XML got the solution:
<http:listener-config name="localhost" port="8085" doc:name="HTTP Listener Configuration" host="0.0.0.0"/>
<http:request-config name="HTTP_Request_Configuration" host="legacy.cafebonappetit.com" port="80" doc:name="HTTP Request Configuration" basePath="/api/2"/>
<flow name="GetDiningInfo">
<http:listener config-ref="localhost" path="/dining" doc:name="HTTP"/>
<http:request config-ref="HTTP_Request_Configuration" path="/menus" method="GET" doc:name="HTTP">
<http:request-builder>
<http:query-param paramName="cafe" value="261"/>
<http:header headerName="Host" value="legacy.cafebonappetit.com"/>
</http:request-builder>
<http:success-status-code-validator values="100..599"/>
</http:request>
<logger level="INFO" doc:name="Logger" message="#[payload]"/>
</flow>

The only way to resolve this issue is to make the server process the request.
Add this line in the xml,
<http:header headerName="Host" value="the_host"/>

You have to delete base path from global configuration of delete path in your xml because it generates url like : http://legacy.cafebonappetit.com/api/2/api/2/menus?cafe=261
here in url api/2/api/2 generated twice so thats why error occured

The server for legacy.cafebonappetit.com cannot handle the header Host including the port (which is valid).
The HTTP connector sends Host: legacy.cafebonappetit.com:80 by default causing the server to reject the request, so you need to explicitly add the Host header, as in the example below.
enter image description here

you can use the code like this
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0"
port="8081" doc:name="HTTP Listener Configuration"/>
<http:request-config name="HTTP_Request_Configuration"
host="legacy.cafebonappetit.com" port="80" basePath="/api/2" doc:name="HTTP
Request Configuration"/>
<flow name="so-testFlow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/dining"
doc:name="HTTP"/>
<http:request config-ref="HTTP_Request_Configuration" path="menus"
method="GET" doc:name="HTTP">
<http:request-builder>
<http:query-param paramName="cafe" value="261"/>
<http:header headerName="Host" value="legacy.cafebonappetit.com"/>
</http:request-builder>
<http:success-status-code-validator values="100..599"/>
</http:request>
</flow>

Use this below code for your issue...
<http:request config-ref="HTTP_Request_Configuration" path="/menus" method="GET" doc:name="HTTP">
<http:request-builder>
<http:query-param paramName="cafe" value="261"/>
<http:header headerName="Host" value="the_host"/>
</http:request-builder>
<http:success-status-code-validator values="100..599"/>
</http:request>

http:request-builder
try to add a header

The below code seems to work.
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8084" doc:name="HTTP Listener Configuration"/>
<http:endpoint exchange-pattern="request-response" method="POST" name="HTTP" address="http://legacy.cafebonappetit.com/api/2/menus?cafe=261" doc:name="HTTP"/>
<flow name="GetDiningInfo">
<http:listener config-ref="HTTP_Listener_Configuration" path="/dining" doc:name="HTTP"/>
<logger level="INFO" doc:name="Logger"/>

Mule flow not able to read the inbound attachmnet

I have this mule flow , where its polling the source folder to read the text file which I am adding as a attachment and sending through REST call , the same attachment I am trying to read in the different flow but inbound attachment is coming as null , please have a look into the code and help me on this.
<flow name="createAttachment" doc:description="Reading file and sending as attachment.">
<file:inbound-endpoint path="src/test/resources/in/attachment/" responseTimeout="10000" doc:name="File"/>
<file:file-to-byte-array-transformer doc:name="File to Byte Array"/>
<!-- <set-attachment attachmentName="#[originalFilename]" value="#[payload]" contentType="multipart/form-data" doc:name="Attachment"/> -->
<set-attachment attachmentName="#[originalFilename]" value="#[payload]" contentType="multipart/form-data" doc:name="Attachment" />
<http:request config-ref="HTTP_Request_Configuration" path="attachment/excel" method="POST" doc:name="HTTP"/>
</flow>
<flow name="readAttachment">
<http:listener config-ref="HTTP_Listener_Configuration" path="attachment/excel" allowedMethods="POST" parseRequest="false" />
<set-payload value="#[message.inboundAttachments['myattachment.txt']]" doc:name="Retrieve Attachments"/>
<set-payload value="#[payload.getInputStream() ]" doc:name="Get Inputstream from Payload"/>
<file:outbound-endpoint path="src/test/resources/out/attachment" responseTimeout="10000" doc:name="File" outputPattern="#[server.dateTime.toString()].pdf"/>
</flow>
I used the following:
<flow name="readAttachment">
<http:listener config-ref="HTTP_Listener_Configuration"
path="/" allowedMethods="POST" parseRequest="false" doc:name="HTTP" />
<byte-array-to-string-transformer doc:name="Byte Array to String"/>
<logger message="#[payload]" level="INFO" doc:name="Logger" /><file:outbound-endpoint path="src/test/resources" connector-ref="File" responseTimeout="10000" doc:name="File"/>
</flow>
When the attachment was received it was automatically parsed to be the payload, so it was just a case of turning the byte array to string.
I hope this helps

Mule http request logging

I'm sending a https request to a third party api and getting back a response of 403. How do I log to the console the request? I want to verify what I'm sending since it works when I curl it. Using Mule 3.7.0
<flow name="EmailFlow" >
<jms:inbound-endpoint queue="outbound.queue" doc:name="email outbound communicationQ" connector-ref="Active_MQ" >
</jms:inbound-endpoint>
<json:object-to-json-transformer doc:name="Object to JSON"/>
<logger message="msg is: #[payload]" level="INFO" doc:name="Logger"/>
<http:request config-ref="https_request_config" path="/api/v1/transmissions" method="POST" doc:name="HTTP">
<http:request-builder>
<http:header headerName="Authorization" value="somekey"/>
<http:header headerName="Content-Type" value="application/json"/>
</http:request-builder>
<http:success-status-code-validator values="403"/>
</http:request>
<logger level="INFO" doc:name="Logger"/>
</flow>
In 3.7 + You can add the following to your log4j2.xml which performs HTTP wire logging:
<AsyncLogger name="org.mule.module.http.internal.HttpMessageLogger" level="DEBUG" />
<AsyncLogger name="com.ning.http" level="DEBUG" />

can anyone help me out
Following code works fine for me. HTH.

I am getting the value using following :-
<logger message=" custom header username ... #[message.inboundProperties['username']]"
level="INFO" doc:name="Logger"/>
You need to pass the XML in the body of postman
UPDATE
I am getting the value as below :-
Use the data mapper after the http:outBound to convert to json response.

Mule ESB: Not able to control the flows from flow1 to flow 2

I have a ServiceFlow and a FileFlow. As soon as the ServiceFlow (Flow1) is triggered, FileFlow (Flow2) should take all the files and process them.
Making the initial state as stopped in Flow2 works only for the first time until Mule server started i.e., for the first triggered execution. Once the flow reaches the first trigger, if I try to keep some files in file:inbound-endpoint it starts processing the files.
But my scenario is based on each trigger only, so the second file has to pick the file. Please help me how to control this in Flow2.
I'm using the below code
<flow name="serviceFlow" doc:name="Flow1">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8081" doc:name="HTTP" contentType="text/xml"
mimeType="text/xml" />
<set-payload value="'Started Processing'" doc:name="Set Payload" />
<async doc:name="Async">
<expression-component doc:name="Expression">
app.registry.FileFlow.start();
</expression-component>
</async>
</flow>
<flow name="FileFlow" doc:name="Flow2" initialState="stopped" >
<file:inbound-endpoint responseTimeout="10000" doc:name="File" path="C:\Users\Desktop\IN"/>
<batch:execute name="businessBatch1" doc:name="Batch Execute"/>
</flow>
Using Mule version: 3.5.1
What I can suggest you is to put a <expression-component doc:name="Expression">app.registry.FileFlow.stop();</expression-component> at the end of second flow so after the second flow is executed it will again make it's initial state "stopped" so that you can trigger the first flow again without fear since the flow2 is stopped.
<flow name="serviceFlow" doc:name="Flow1">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8081" doc:name="HTTP" contentType="text/xml"
mimeType="text/xml" />
<set-payload value="'Started Processing'" doc:name="Set Payload" />
<async doc:name="Async">
<expression-component doc:name="Expression">
app.registry.FileFlow.start();
</expression-component>
</async>
</flow>
<flow name="FileFlow" doc:name="Flow2" initialState="stopped" >
<file:inbound-endpoint responseTimeout="10000" doc:name="File" path="C:\Users\Desktop\IN"/>
<batch:execute name="businessBatch1" doc:name="Batch Execute"/>
<expression-component doc:name="Expression">
app.registry.FileFlow.stop();
</expression-component>
