解析zip文件

Question

我正在使用nutch 1.15来抓取包含由file1.txt，file2.txt和file3.txt组成的zip文件的链接。

我在“ plugin.includes”中使用了parse-zip，parse-tika插件，但是它无法抓取文本文件的内容并将其编入索引。

已解析的内容将以这种方式返回

"content" : "file1.txt\nfile2.txt\nfile3.txt\n"

为什么无法获取file1.txt等的内容？

从regex-urlfilter.txt中删除了zip，

#-(?i)\.(gif|jpg|png|ico|css|sit|eps|wmf|zip|ppt|mpg|xls|gz|rpm|tgz|mov|exe|jpeg|bmp|js)$
-(?i)\.(gif|jpg|png|ico|css|sit|eps|wmf|ppt|mpg|xls|gz|rpm|tgz|mov|exe|jpeg|bmp|js)$

plugin.includes in nutch-site.xml：

<property>
    <name>plugin.includes</name>
    <value>protocol-http|protocol-httpclient|urlfilter-regex|parse-(html|text|tika|zip|metatags)|index-(basic|anchor|metadata)|query-(basic|site|url)|response-(json|xml)|summary-basic|scoring-opic|urlnormalizer-(pass|regex|basic)|indexer-elastic</value>
</property>
<property>
    <name>http.content.limit</name>
    <value>-1</value>
</property>

parse-plugins.xml文件：

<parse-plugins>

  <!--  by default if the mimeType is set to *, or
        if it can't be determined, use parse-tika -->
    <mimeType name="*">

        <alias name="parse-zip"
            extension-id="org.apache.nutch.parse.zip.ZipParser" />
    </aliases>

</parse-plugins>

我在螺母侧缺少任何配置吗？
