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.
"<logger name="org.openmrs.module">
<level value="INFO" />
</logger>"
<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 -->
