在WildFly 8中转储HTTP请求 [英] Dump HTTP requests in WildFly 8

问题描述

要在开发过程中调试HTTP请求，我希望我的WildFly 8应用程序服务器将HTTP请求(包括请求方法和标头)转储到日志文件中. server.log很好.

To debug HTTP requests during development, I would like my WildFly 8 application server to dump HTTP requests, including request method and headers, to a log file. server.log would be fine.

在WildFly的HTTP子系统的来源中，我找到了

In the sources of WildFly's HTTP subsystem, I found RequestDumpingHandler and the corresponding logging category io.undertow.request.dump

但是，我不知道如何安装该标头，以便将其应用于我的应用程序(带有一些静态资源和JAX-RS处理程序的WAR)所服务的所有请求.

However, I cannot figure out, how to install that header so that it is applied for all requests served by my application (a WAR with some static resources and JAX-RS handler).

相应的文档页面( Undertow Web子系统配置)没有并没有真正解释处理程序.配置部分中有一个<handler>元素

The corresponding documentation page (Undertow web subsystem configuration) doesn't really explain handlers. There is a <handler> element in the configuration section

<?xml version="1.0" ?>
<server xmlns="urn:jboss:domain:2.1">
    ...
    <profile>
        ...
        <subsystem xmlns="urn:jboss:domain:undertow:1.1">
        <buffer-cache name="default"/>
        <server name="default-server">
            <http-listener name="default" socket-binding="http"/>
            <host name="default-host" alias="localhost">
                <location name="/" handler="welcome-content"/>
                <filter-ref name="server-header"/>
                <filter-ref name="x-powered-by-header"/>
            </host>
        </server>
        <servlet-container name="default">
            <jsp-config/>
        </servlet-container>
        <handlers>
            <file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>
            <!-- <dump-request /> ?? or something?-->
        </handlers>
        <filters>
            <response-header name="server-header" header-name="Server" header-value="WildFly/8"/>
            <response-header name="x-powered-by-header" header-name="X-Powered-By" header-value="Undertow/1"/>
        </filters>
        </subsystem>
        ...
    </profile>
    ...
</server>

但据我所知，在那里只需要<file>和代理(?).

but as far as I can tell, only <file> and proxy are expected there(?).

如何在WildFly中记录传入的HTTP请求的全部详细信息?我知道我可以在JAX-RS层上安装一些日志记录机制，但是我希望有一个转储机制可以同时处理这两种情况REST API调用和静态服务资源.

How can I log full details of incoming HTTP requests in WildFly? I know I could install some logging mechanism at the JAX-RS layer, but I would like to have one dump mechanism that handles both REST API calls and statically served resources.

推荐答案

您需要将RequestDumpingHandler添加到处理程序链中.

You would need to add RequestDumpingHandler to your handler chain.

作为wildfly 8.1的一部分，尚不可能以友好的方式实现.

As part of wildfly 8.1, that is not yet possible in a friendly way.

此功能在8.2和9中得到了改进，因此您可以通过添加以下内容进行配置:

This is improved in 8.2 and 9 so you will be able to configure this by adding something like this:

<host name="default-host" >
     .....
     <filter-ref name="request-dumper"/>
</host>
....
<filters>
    ...
    <filter name="request-dumper" class-name="io.undertow.server.handlers.RequestDumpingHandler" module="io.undertow.core" />
</filters>

现在，仅在8.1中的

选项将添加ServletExtension http ://undertow.io/undertow-docs/undertow-docs-1.2.0/#servlet-extensions

in 8.1 only option now would be to add ServletExtension http://undertow.io/undertow-docs/undertow-docs-1.2.0/#servlet-extensions

会将这个RequestDumpingHandler添加到外链.

that would add this RequestDumpingHandler to outer chain.

FWIW 8.2发行版几乎已准备就绪，因此您可以等待它或仅为8.x分支构建源.

FWIW 8.2 release is almost ready, so you could wait for it or just build sources for 8.x branch.

要通过CLI添加上述配置，您可以使用:

To add above config via CLI, you can use:

/subsystem=undertow/configuration=filter/custom-filter=request-dumper:add(class-name="io.undertow.server.handlers.RequestDumpingHandler",  module="io.undertow.core")
/subsystem=undertow/server=default-server/host=default-host/filter-ref=request-dumper:add
