Tomcat在哪里附加/到目录路径？ [英] Where does Tomcat append / to directory paths?

问题描述

假设我的Tomcat webapps目录如下所示：

Suppose my Tomcat webapps directory looks like this:

webapps/
webapps/fooapp/
webapps/fooapp/WEB-INF/
webapps/fooapp/WEB-INF/web.xml
webapps/fooapp/bardir/

当我对 / fooapp / bardir 发出GET请求时，Tomcat发现webapps / fooapp / bardir是一个目录并发送将302返回 / fooapp / bardir / （最后用斜杠）。

When I make a GET request for /fooapp/bardir, Tomcat sees that webapps/fooapp/bardir is a directory and sends back a 302 to /fooapp/bardir/ (with a slash at the end).

这是我的问题： Tomcat源代码中的会发生这种情况吗？（我正在研究6.0.x，但任何版本的正确答案都是一个很好的起点。）

Here is my question: Where in the Tomcat source code does this take place? (I'm looking at 6.0.x but a correct answer for any version would be a great starting point.)

我能在这个主题上找到的唯一参考资料是 Catalina Functional Specifications ，其中说明了默认Servlet：

The only reference material I can find on this subject is in the Catalina Functional Specifications which states, regarding the Default Servlet:

在此se处理的每个HTTP GET请求上rvlet，应执行以下处理：

On each HTTP GET request processed by this servlet, the following processing shall be performed:

[...]

• 如果请求的资源是目录：
  
  
  
  
  • 如果请求路径不以/结尾，则重定向到附加了/的相应路径欢迎文件中的相对引用已正确解析。
  
  

  但是，此功能似乎不在org.apache.catalina.servlets.DefaultServlet中;或者至少，它并不是唯一的：如果我将web.xml中的默认servlet替换为 servlet-class不存在的servlet，则目录路径仍会返回302 添加斜杠，而其他每个请求都会按预期返回错误。

  However, this functionality does not appear to be in org.apache.catalina.servlets.DefaultServlet; or at least, it's not there exclusively: if I replace the default servlet in web.xml with a servlet whose servlet-class does not exist, directory paths still come back 302 to add the slash, while every other request comes back with an error as expected.

  推荐答案

  我认为它发生在 org.apache.tomcat.util.http.mapper.Mapper ，即在 internalMapWrapper（Context，CharChunk，MappingData）方法。

  I think it happens in org.apache.tomcat.util.http.mapper.Mapper, namely in the internalMapWrapper (Context, CharChunk, MappingData) method.

  但不幸的是我不太确定 - 也许这真的是一个更适合 tomcat-users 邮件列表。很抱歉没有更好的答案。

  But unfortunately I'm not really sure -- maybe this really is a question better suited for the tomcat-users mailing list. Sorry for not having a better answer.
