logRequestResult
Description
Logs both, the request and the response.
This directive is a combination of logRequest and logResult.
See logRequest for the general description how these directives work.
Example
// using logRequestResult
// handle request to optionally generate a log entry
BiFunction<HttpRequest, HttpResponse, Optional<LogEntry>> requestMethodAsInfo =
(request, response) ->
(response.status().isSuccess()) ?
Optional.of(
LogEntry.create(
request.method().name() + ":" + response.status().intValue(),
InfoLevel()))
: Optional.empty(); // not a successful response
// handle rejections to optionally generate a log entry
BiFunction<HttpRequest, List<Rejection>, Optional<LogEntry>> rejectionsAsInfo =
(request, rejections) ->
(!rejections.isEmpty()) ?
Optional.of(
LogEntry.create(
rejections
.stream()
.map(Rejection::toString)
.collect(Collectors.joining(", ")),
InfoLevel()))
: Optional.empty(); // no rejections
final Route route = get(() -> logRequestResultOptional(
requestMethodAsInfo,
rejectionsAsInfo,
() -> complete("logged")));
// tests:
testRoute(route).run(HttpRequest.GET("/")).assertEntity("logged");
}
// A function for the logging of Time
public static Optional<LogEntry> printResponseTime(HttpRequest request, HttpResponse response, Long requestTime) {
if (response.status().isSuccess()) {
Long elapsedTime = (requestTime - System.nanoTime()) / 1000000;
return Optional.of(
LogEntry.create(
"Logged Request:" + request.method().name() + ":" + request.getUri() + ":" + response.status() + ":" + elapsedTime,
InfoLevel()));
} else {
return Optional.empty(); //not a successfull response
}
}
}
Longer Example
This example shows how to log the response time of the request using the Debugging Directive
// using logRequestResultOptional for generating Response Time
// handle request to optionally generate a log entry
BiFunction<HttpRequest, HttpResponse, Optional<LogEntry>> requestMethodAsInfo =
(request, response) -> {
Long requestTime = System.nanoTime();
return printResponseTime(request, response, requestTime);
};
// handle rejections to optionally generate a log entry
BiFunction<HttpRequest, List<Rejection>, Optional<LogEntry>> rejectionsAsInfo =
(request, rejections) ->
(!rejections.isEmpty()) ?
Optional.of(
LogEntry.create(
rejections
.stream()
.map(Rejection::toString)
.collect(Collectors.joining(", ")),
InfoLevel()))
: Optional.empty(); // no rejections
final Route route = get(() -> logRequestResultOptional(
requestMethodAsInfo,
rejectionsAsInfo,
() -> complete("logged")));
// tests:
testRoute(route).run(HttpRequest.GET("/")).assertEntity("logged");
}
// A function for the logging of Time
public static Optional<LogEntry> printResponseTime(HttpRequest request, HttpResponse response, Long requestTime) {
if (response.status().isSuccess()) {
Long elapsedTime = (requestTime - System.nanoTime()) / 1000000;
return Optional.of(
LogEntry.create(
"Logged Request:" + request.method().name() + ":" + request.getUri() + ":" + response.status() + ":" + elapsedTime,
InfoLevel()));
} else {
return Optional.empty(); //not a successfull response
}
}
