[esb-issues] [JBoss JIRA] Commented: (JBESB-3191) Need way to automatically convert HTTP request to XML payload in default message body

Need way to automatically convert HTTP request to XML payload in default message body ------------------------------------------------------------------------------------- Key: JBESB-3191 URL: https://jira.jboss.org/jira/browse/JBESB-3191 Project: JBoss ESB Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Transports Affects Versions: 4.7 Environment: SOA-P 5.0 GA Reporter: Aaron Pestel Currently, the http-gateway puts the payload of the HTTP message (whatever is POSTed) in the default message body of the ESB message. The information in the HttpRequest (uri, query string parameters, http properties, etc.) is stored in a Java object in the ESB message properties. In this way, only a custom action with Java (or possibly a script like Groovy) can access the actual HttpRequest data. In cases of GET or many other RESTful type scenarios, the data in the HttpRequest is really the most important data and should be easy to access. The http_gateway quickstart has an example action that gets the HttpRequest object from the message, converts it to XML via XStream, and stores it in the default message body. It seems this would be an ideal option to be able to specify on the http-gateway rather than having to write a custom action to do this. In this way, one could use the ESB to present a SOAP service as a REST service, by only writing a few XSLTs and no Java code. For example, the REST GET request could come in through the gateway and be automatically converted to XML. An XSLT action could convert the HttpRequest XML to a SOAP message. A SoapProxy could route the message to a SOAP service. Another XLST action could convert the SOAP response into a raw XML response or even a JSON response. All this could be done with no custom Java code, if there were a way for the http-gateway to automatically put the HttpRequest on the message body as XML. One possible way to implement this would be to add a new property flag like this to the http-gateway: <http-gateway useHttpRequestXmlForMessageBody='true'/> Or, one could possibly add a messageComposer property capability like the file-providers allow with an out of the box implementation that converts the HttpRequest object to XML for the default ESB message body. That would be even more flexible, but slightly more complex and would need good documentation. In the end, the goal is that via simple configuration, the http-gateway can put something like the below XML in the default ESB message body rather than nothing in the GET case or rather than whatever was POSTed in the HTTP POST case: ---------------------------------------------------------------------------------------------------------- <org.jboss.soa.esb.http.HttpRequest> <contextPath>/Quickstart_http_gateway</contextPath> <localAddr>127.0.0.1</localAddr> <localName>localhost.localdomain</localName> <method>GET</method> <pathInfo>/XXXX/yyy</pathInfo> <protocol>HTTP/1.1</protocol> <queryString>a=1,b=2</queryString> <remoteAddr>127.0.0.1</remoteAddr> <remoteHost>127.0.0.1</remoteHost> <contentLength>-1</contentLength> <requestURI>/Quickstart_http_gateway/http/index/XXXX/yyy</requestURI> <scheme>http</scheme> <serverName>localhost</serverName> <requestPath>/http/index</requestPath> <pathInfoTokens> <string>XXXX</string> <string>yyy</string> </pathInfoTokens> <queryParams> <entry> <string>a</string> <string-array> <string>1,b=2</string> </string-array> </entry> </queryParams> <headers> <org.jboss.soa.esb.http.HttpHeader> <name>host</name> <value>localhost:8080</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>user-agent</name> <value>Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.11) Gecko/2009061118 Fedora/3.0.11-1.fc9 Firefox/3.0.11</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>accept</name> <value>text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>accept-language</name> <value>en-us,en;q=0.5</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>accept-encoding</name> <value>gzip,deflate</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>accept-charset</name> <value>ISO-8859-1,utf-8;q=0.7,*;q=0.7</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>keep-alive</name> <value>300</value> </org.jboss.soa.esb.http.HttpHeader> <org.jboss.soa.esb.http.HttpHeader> <name>connection</name> <value>keep-alive</value> </org.jboss.soa.esb.http.HttpHeader> </headers> </org.jboss.soa.esb.http.HttpRequest> ----------------------------------------------------------------------------------------------------------
