logging - 如何在 groovyConsole 中显示 HTTPBuilder 日志

Question

问题

我收到 groovyx.net.http.HttpResponseException: Not Found并想查看来自 HTTPBuilder 的日志.我正在使用 Groovy 2.1.9 与 groovyConsole .

我试过的

所以我查了 this blog post说的是添加 log4j.xml至 groovy.home/conf/ .我这样做了，这是我的文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <param name="Target" value="System.out" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{ISO8601} %-5p  %c{1} - %m%n" />
        </layout>
    </appender>

    <category name="groovyx.net.http">
        <priority value="DEBUG" />
    </category>

    <!-- Use DEBUG to see basic request/response info;  
         Use TRACE to see headers for HttpURLClient. -->
    <category name="groovyx.net.http.HttpURLClient">
        <priority value="INFO" />
    </category>

    <category name="org.apache.http">
        <priority value="DEBUG" />
    </category>
    <category name="org.apache.http.headers">
        <priority value="DEBUG" />
    </category>
    <category name="org.apache.http.wire">
        <priority value="DEBUG" />
    </category>

    <root>
        <priority value="INFO" />
        <appender-ref ref="console" />
    </root>
</log4j:configuration>

这是我在控制台中运行的脚本:

    log.debug "http is instanceof ${http.getClass()}" //this is printed

   def sslContext = SSLContext.getInstance("SSL")              
   sslContext.init(null, [ new X509TrustManager() {
     public X509Certificate[] getAcceptedIssuers() {null}
     public void checkClientTrusted(X509Certificate[] certs, String authType) { }
     public void checkServerTrusted(X509Certificate[] certs, String authType) { }
   } ] as TrustManager[], new SecureRandom())
   def sf = new SSLSocketFactory(sslContext, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER)
   def httpsScheme = new Scheme("https", sf, 4483)
   http.client.connectionManager.schemeRegistry.register( httpsScheme )
   //================================

    //the next line throws the exeption...
    http.post(path: '/method', contentType: ContentType.JSON, query: [param: '1000']) { resp, reader ->
        println "resp is instanceof ${resp.getClass()}"
        println "and reader is instanceof ${reder.getClass()}"

        println "response status: ${resp.statusLine}"
        println 'Headers: -----------'
        resp.headers.each { h ->
          println " ${h.name} : ${h.value}"
        }
        println 'Response data: -----'
        System.out << reader
        println '\n--------------------'

    }
  } 
}

编辑 : 我的 HttpResponseException 解决了，我有一个 /在请求中不必要，但仍然没有出现构建器日志。

HTTPBuilder使用 commons-logging，所以你必须将 commons-logging 的输出桥接到 log4j。不幸的是，log4j 1.2 不支持开箱即用。所以我简化了你的例子并切换到 SLF4J ，这是一个“Java 的简单日志外观”。下面的配置仍然使用 log4j，所以你仍然需要你的 log4j.xml到位 ( groovy.home/conf/ )。详细解释见 Bridging legacy APIs .

@Grapes([
    @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.6'),
    // This brings in slf4j, log4j12 (as dependancies) and the bridge to log4j
    @Grab(group='org.slf4j', module='slf4j-log4j12', version='1.7.7'),
    // This brings in the bridge to commons-logging
    @Grab(group='org.slf4j', module='jcl-over-slf4j', version='1.7.7')
])

import org.slf4j.LoggerFactory
import groovyx.net.http.*

// get a logger for the script
def log = LoggerFactory.getLogger('script')

def http = new HTTPBuilder('http://www.google.com')
log.info "http is instanceof ${http.getClass()}" //this is printed

http.get( path : '/search', contentType : ContentType.TEXT, query : [q:'Groovy'] ) { resp, reader ->
    log.debug "response status: ${resp.statusLine}"
    println 'Done'
}
