Question

我正在Linux上使用tomcat 9.0，python 3.6。我的测试脚本适用于Get请求，但不适用于Post请求。每当我发送发布请求时，该请求都将挂起，看起来它正在等待sys.stdin。如果我使用form = cgi.FieldStorage（），它也会挂起。如果我打印出content_length，则为None。

import sys
# Import modules for CGI handling 
import cgi, cgitb

import os
import traceback

sys.stderr = sys.stdout

print("Content-type:text/html\r\n\r\n")
print("<html>")
print("<head>")
print("<title>Hello - Second CGI Program</title>")
print("</head>")
print("<body>")

print("########################################")

cgitb.enable()

if os.environ['REQUEST_METHOD'] == 'GET':
# Create instance of FieldStorage 

   #cgi.print_environ_usage()

   form = cgi.FieldStorage()

   # Get data from fields
   first_name = form.getvalue('first_name')
   last_name  = form.getvalue('last_name')

elif os.environ['REQUEST_METHOD'] == 'POST':
# Create instance of FieldStorage 


   # cgi.print_environ_usage()
   #print(os.environ['CONTENT_LENGTH'])
   #this does not work, the request never response, looks like waiting for something
   form = cgi.FieldStorage() 


   # Get data from fields
   first_name = form.getvalue('first_name')
   last_name  = form.getvalue('last_name')

elif os.environ['REQUEST_METHOD'] == 'POST2':
   # this does not work either, taking suggestion from other post.
   POST={}
   post_length = int(os.environ['CONTENT_LENGTH'])
    # post_length stores byte count, but stdin.read, apparently, takes the character count
   post_string = sys.stdin.buffer.read(post_length).decode('utf-8')

   args=post_string.split('&')

   for arg in args:
      t=arg.split('=')
      if len(t)>1: k, v=arg.split('='); POST[k]=v

   # Get data from fields
   first_name = POST.get('first_name')
   last_name  = POST.get('last_name')

else:
   first_name = 'None'
   last_name  = 'None'



#print("<h2>Hello %s %s</h2>" % (first_name, last_name))


print("</body>")
print("</html>")

测试时，我使用curl命令，例如

curl -X "POST" "http://localhost:8080/test.py?first_name=john&last_name=black"
curl -X "GET" "http://localhost:8080/test.py?first_name=john&last_name=black"

Python CGI脚本无法处理POST请求
