Question

hunchentoot-cgi现在基本上可以与hunchentoot-1.2.2一起使用了一些修改：

在#'handle-cgi-script中，将:external-format tbnl::+latin-1+替换为:external-format tbnl::+utf-8+

正如WhiteCat建议的那样，使用#'make-pathname如下：

(pushnew (hunchentoot-cgi::create-cgi-dispatcher-and-handler
          "/cgi-bin/"
          (make-pathname :directory '(:absolute "media" "E"
                                                "myapp" "cgi-bin")))
         dispatch-table :test #'equal)

但是，我不明白为什么python脚本无法获取POSTed参数，即访问http://127.0.0:8000/cgi-bin/login.py?cmd=view时，login.py可以成功获取参数cmd的值，但是当发布时以下表单，login.py无法获取所有发布的值（无论是否隐藏）：

<html><body>
  <form method='POST' action='cgi-bin/login.py'>
    <input type='text' name='userid'>
    <input type='password' name='userpwd'>
    <input type='submit' value='Login'>
    <input type='hidden' name='cmd' value='view'>
  </form>
</body></html>

我猜hunchentoot-cgi没有根据环境将发布的参数传递给python脚本：

GET http://127.0.0.1:8000/cgi-bin/nav.py?userid=xyz&cmd=view
传递给python脚本的环境是：

(SERVER_SOFTWARE=hunchentoot/1.2.2
 SERVER_NAME=127.0.0.1 GATEWAY_INTERFACE=CGI/1.1
 SERVER_PROTOCOL=HTTP/1.1 SERVER_PORT=8000 REQUEST_METHOD=GET
 CONTENT_TYPE=text/html CONTENT_LENGTH=NIL
 SCRIPT_NAME=/cgi-bin/nav.py QUERY_STRING=userid=xyz&cmd=view
 REMOTE_ADDR=127.0.0.1 HTTP_HOST=NIL
 REQUEST_URI=/cgi-bin/nav.py?userid=xyz&cmd=view SERVER_ADDR=NIL
 HTTP_USER_AGENT=Mozilla/5.0 (X11; Linux i686; rv:9.0.1) Gecko/20100101 Firefox/9.0.1
 HTTP_REFERER=http://127.0.0.1:8000/)

发布到/cgi-bin/nav.py

(SERVER_SOFTWARE=hunchentoot/1.2.2
 SERVER_NAME=127.0.0.1 GATEWAY_INTERFACE=CGI/1.1
 SERVER_PROTOCOL=HTTP/1.1 SERVER_PORT=8000 REQUEST_METHOD=POST
 CONTENT_TYPE=text/html CONTENT_LENGTH=NIL
 POST_PARAMETERS=((userid . xyz) (userpwd . 123) (cmd . view))
 SCRIPT_NAME=/cgi-bin/nav.py QUERY_STRING=NIL REMOTE_ADDR=127.0.0.1     
 HTTP_HOST=NIL REQUEST_URI=/cgi-bin/nav.py SERVER_ADDR=NIL
 HTTP_USER_AGENT=Mozilla/5.0 (X11; Linux i686; rv:9.0.1) Gecko/20100101 Firefox/9.0.1

我认为“CONTENT_LENGTH = NIL”是错误的，不是吗？

请点亮我，谢谢！

在hunchentoot-cgi.lisp乱糟糟的黑客攻击后，现在可以正常工作了。但是，希望Cyrus Harmon（http://cyrusharmon.org/blog）能够发布下一个规范版本。

旧版本的hunchentoot-cgi根本不支持CGI数据。尝试0.3或更高版本并在github上提出问题，如果这仍然不适合你。

为什么python脚本不能从hunchentoot-cgi获取post参数？
