客户端代码通过ajax请求将对象（在POST请求主体中）或查询字符串（如果使用GET方法）提交给Python cgi脚本。请注意，对象/查询字符串参数不是来自于一个。
<form> or <isindex>.
我如何使用标准库模块（例如，cgi）从服务器端Python脚本中检索这些参数？
Thanks very much
EDIT:
@codeape: Thanks, but wouldn t that work only for submitted forms? In my case, no form is being submitted, just an asynchronous request.
Using your script, len(f.keys()) returns 0 if no form is submitted! I can probably recast the request as a form submission, but is there a better way?
您可以使用cgi.FieldStorage类。示例CGI脚本：
#! /usr/bin/python
import cgi
from os import environ
import cgitb
cgitb.enable()
print "Content-type: text/plain"
print
print "REQUEST_METHOD:", environ["REQUEST_METHOD"]
print "Values:"
f = cgi.FieldStorage()
for k in f.keys():
print "%s: %s" % (k, f.getfirst(k))
codeape已经回答了这个问题。仅供记录，要理解的是，HTTP请求的发出方式是完全正交的 - 服务器接收到的是HTTP请求，没有其他。
@codeape , @bruno desthuilliers:
Indeed, cgi.FieldStorage() retrieves the parameters. The output I was getting earlier was apparently due to my passing the parameters as a string (JSON.stringify() object) in the body of the request -- rather than as key-value pairs.
Thanks
