J'ai réussi à activer la journalisation des accès dans Tomcat en modifiant le fichier conf/server.xml et en décommentant l'entrée de la vanne org.apache.catalina.valves.AccessLogValve. J'aimerais pouvoir vider le contenu de la charge utile du POST. Il ne semble pas que l'une des options du pattern le fasse. Y a-t-il un moyen intégré de le faire? Est-ce que j'utilise AccessLogValve?Enregistrement de la charge utile des POST sur Tomcat
Puisqu'il n'y avait pas une suggestion d'un moyen intégré pour obtenir la charge utile POST, je suis allé de l'avant et a écrit un filtre personnalisé qui déverse le contenu de la charge utile. Plus précisément:
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
LOG.debug("payload: " + requestWrapper.getRequestBody());
et web.xml:
<filter>
<filter-name>PayloadLoggingFilter</filter-name>
<filter-class>com.host.PayloadLoggingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PayloadLoggingFilter</filter-name>
<url-pattern>/resources/*</url-pattern>
</filter-mapping>
Si le poste est une forme (application/x-www-urlencoded), vous pouvez utiliser ExtendedAccessLogValve,
http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/valves/ExtendedAccessLogValve.html
Vous devez sélectionner les paramètres individuels dans le modèle comme celui-ci,
x-P(param_name)
@ZZ: si ce n'est pas une forme? –
Si ce n'est pas un formulaire, vous ne pouvez pas vraiment vous connecter le corps du message. Le format du journal est défini par http://www.w3.org/TR/WD-logfile.html. Il ne prend pas en charge le corps du message arbitraire, qui peut être binaire et énorme, en cas de téléchargement de fichier. –
Malheureusement, ce n'est pas le cas pour moi. Je ne publie pas de contenu en tant que paramètre, bien que la taille de la charge utile ne soit probablement pas supérieure à quelques kb. – Tim
Voir RequestDumperValve ou RequestDumperFilter ici: http://tomcat.apache.org/tomcat-5.5-doc/config/valve.html#Request_Dumper_Valve il fait ce que vous voulez.
RequestDumperFilter ne consigne pas la charge POST, uniquement les en-têtes et l'URL (y compris la chaîne de requête) – ChristophK
Dans votre webapp web.xml ajouter:
<filter>
<filter-name>PayloadLoggingFilter</filter-name>
<filter-class>your.MyLogFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PayloadLoggingFilter</filter-name>
<url-pattern>/path/*</url-pattern>
</filter-mapping>

D'où vient le 'requestWrapper'? Ou est-ce supposé être l'objet 'request'? – andho
requestWrapper vient d'ici aka MyRequestWrapper. Ça marche! http://natch3z.blogspot.co.uk/2009/01/read-request-body-in-filter.html – goat
