ResponseHighlighterInterceptor

This detects when a request is coming from a browser and returns HTML with syntax highlighted XML/JSON instead of just the raw text. In other words, if a user uses a browser to request "http://localhost:8080/openmrs/ws/fhir/Person/d9648997-4e01-406e-b47b-c00cb9b143bb" by typing this address into their URL bar, they will get nice formatted HTML back with a human readable version of the content. This is helpful for testers.

LoggingInterceptor

This  can be used to generate a new log line (via SLF4j) for each incoming request. 

Example log line:

2015-08-09 17:29:45 INFO  accesslog:103 - Source[127.0.0.1] Operation[read Person/d9648997-4e01-406e-b47b-c00cb9b143bb] UA[Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.134 Safari/537.36] Params[]

The following substitution variables are supported:

${id}The resource ID associated with this request (or "" if none)
${idOrResourceName}The resource ID associated with this request, or the resource name if the request applies to a type but not an instance, or "" otherwise
${operationName}If the request is an extended operation (e.g. "$validate") this value will be the operation name, or "" otherwise
${operationType}A code indicating the operation type for this request, e.g. "read", "history-instance", "extended-operation-instance", etc.)
${remoteAddr}The originaring IP of the request
${requestHeader.XXXX}The value of the HTTP request header named XXXX. For example, a substitution variable named "${requestHeader.x-forwarded-for} will yield the value of the first header named "x-forwarded-for", or "" if none.
${requestParameters}The HTTP request parameters (or "")
${responseEncodingNoDefault}The encoding format requested by the client via the _format parameter or the Accept header. Value will be "json" or "xml", or "" if the client did not explicitly request a format
${servletPath}The part of thre requesting URL that corresponds to the particular Servlet being called (see HttpServletRequest.getServletPath())


You have to edit FHIRRESTServer.java file in order to add/remove this variables.

For see these logs in the log file you will need to edit apache-tomcat-7.0.59/webapps/openmrs/WEB-INF/classes/log4j.xml file.

 

Added this entry
"<logger name="org.openmrs.module">
<level value="INFO" />
</logger>"
and add also

<appender name="file" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="false" />
<param name="maxFileSize" value="10000KB" />
<param name="maxBackupIndex" value="5" />
<!-- For Tomcat -->
<param name="file" value="${catalina.home}/logs/openmrs.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
</layout>
</appender>

Edit the below part as well.

<root>
<level value="INFO" />
<appender-ref ref="CONSOLE" />
<appender-ref ref="file" />
</root>
