[英]Python simple web server
I am trying to to print some simple variables using the built in HTTP server in Python 我试图使用Python内置的HTTP服务器打印一些简单的变量
class WebServer:
def __init__(self):
from BaseHTTPServer import HTTPServer
import urlparse
server = HTTPServer(('', 8080), self.do_GET)
server.serve_forever()
def do_GET(self):
parsed_path = urlparse.urlparse(self.path)
message_parts = [
'CLIENT VALUES:',
'client_address=%s (%s)' % (self.client_address, self.address_string()),
'command=%s' % self.command,
'path=%s' % self.path,
'real path=%s' % parsed_path.path,
'query=%s' % parsed_path.query,
'request_version=%s' % self.request_version,
'',
'SERVER VALUES:',
'server_version=%s' % self.server_version,
'sys_version=%s' % self.sys_version,
'protocol_version=%s' % self.protocol_version,
'',
'HEADERS RECEIVED:',
]
for name, value in sorted(self.headers.items()):
message_parts.append('%s=%s' % (name, value.rstrip()))
message_parts.append('')
message = '\r\n'.join(message_parts)
self.send_response(200)
self.end_headers()
self.wfile.write(message)
return
But i seem to get this error: 但我似乎得到这个错误:
Exception happened during processing of request from ('10.0.1.3', 52251)
Traceback (most recent call last):
File "/usr/lib/python2.7/SocketServer.py", line 295, in _handle_request_noblock
self.process_request(request, client_address)
File "/usr/lib/python2.7/SocketServer.py", line 321, in process_request
self.finish_request(request, client_address)
File "/usr/lib/python2.7/SocketServer.py", line 334, in finish_request
self.RequestHandlerClass(request, client_address, self)
TypeError: do_GET() takes exactly 1 argument (4 given)
----------------------------------------
def do_GET(self): seems to be receiving more then just self, what am i missing? def do_GET(self):似乎接收的只是自我,我缺少什么?
You're passing in a function, when a BaseHTTPRequestHandler
is expected. 当您需要
BaseHTTPRequestHandler
时,您正在传入函数。 In other words, Python is trying to instantiate your object using a BaseHTTPRequestHandler
__init__
method, but you've provided a function that takes a different amount of arguments. 换句话说,Python正在尝试使用
BaseHTTPRequestHandler
__init__
方法实例化您的对象,但是您提供了一个带有不同数量参数的函数。
Instead of passing a plain function, sublcass BaseHTTPRequestHandler
. 而不是传递普通函数,sublcass
BaseHTTPRequestHandler
。 The example linked by @dm03514 in the comments will get you started. @ dm03514在评论中链接的示例将帮助您入门。
Inherit WebServer
from a Request Handler like this: 从请求处理程序继承
WebServer
,如下所示:
class WebServer(BaseHTTPRequestHandler):
You will probably have to change your imports for that. 您可能必须更改您的导入。
Then pass it as an argument to HTTPServer
like this: 然后将它作为参数传递给
HTTPServer
如下所示:
server = HTTPServer(('', 8080), WebServer)
