尝试获取GET和POST数据时出现此错误。
Exception happened during processing of request from ('127.0.0.1', 62635)

代码
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
import SocketServer
import cgitb; cgitb.enable()
import cgi
class GP(BaseHTTPRequestHandler):
def _set_headers(self):
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_HEAD(self):
self._set_headers()
def do_GET(self):
self._set_headers()
form = cgi.FieldStorage()
print form.getvalue["foo"]
self.wfile.write("<html><body><h1>Get Request Received!</h1></body></html>")
def do_POST(self):
self._set_headers()
form = cgi.FieldStorage()
print form.getvalue["foo"]
self.wfile.write("<html><body><h1>POST Request Received!</h1></body></html>")
def run(server_class=HTTPServer, handler_class=GP, port=8088):
server_address = ('', port)
httpd = server_class(server_address, handler_class)
print 'Server running at localhost:8088...'
httpd.serve_forever()
run()
运行代码，我得到了以上错误。这段代码有什么问题？
python server1.py
curl http://localhost:8088?foo=bar
curl -d "foo=bar" http://localhost:8088
要解决即时错误，可以使用：
form.getvalue("foo")
代替：
form.getvalue["foo"]
这导致：
TypeError: 'instancemethod' object has no attribute '__getitem__'
另外（如/sf/answers/1756438141/中所建议），您可能需要使用：
form = cgi.FieldStorage(
fp=self.rfile,
headers=self.headers,
environ={'REQUEST_METHOD': 'POST'}
)
代替：
form = cgi.FieldStorage()
在POST请求处理程序中。
在GET请求处理程序中，您可能要使用urlparse.parse_qs（对于Python 2）或urllib.parse.parse_qs（对于Python 3）代替cgi.FieldStorage。
