POST'ların Tomcat'e Günlük Yüklenmesi

Question

Tomcat'ta, conf/server.xml dosyasını düzenleyerek ve org.apache.catalina.valves.AccessLogValve Valfı girişini kaldırarak Tomcat'te erişim günlüğünü etkinleştirmeyi başardım. POST'un yükünün içeriğini dökmek istiyorum. Desendeki herhangi bir seçenek bunu yapmayacaktır. Bunu yapmak için bir yol var mı? AccessLogValve kullanıyor musunuz? sonrası bir form (application/x-www-urlencoded), kullanabilirsiniz ExtendedAccessLogValve ise

Answer 1

POST yükünü almak için yerleşik bir öneri olmadığından, devam ettim ve yükün içeriğini dökülen özel bir süzgeç yazdım. Özellikle:

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, 
        FilterChain chain) throws IOException, ServletException { 
    HttpServletRequest request = (HttpServletRequest) servletRequest; 
    LOG.debug("payload: " + requestWrapper.getRequestBody()); 

ve web.xml: Burada

<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> 

Answer 2

, Böyle desende bireysel parametreleri seçmek zorunda

Answer 3

Bkz RequestDumperValve veya RequestDumperFilter: http://tomcat.apache.org/tomcat-5.5-doc/config/valve.html#Request_Dumper_Valve o istediğini yapar. senin Webapp web.xml eklenti olarak

Answer 4

1. :

   <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> 
   

2. sizin Filtre Oluştur:
