Ich benutze Python-Socket und Epoll, um einen Webserver zu erstellen. Mein Betriebssystem ist Linux CentOS 6, Meine Python-Version ist Python 2.7.8. Mein Quellcode ist:Python-Socket und Epoll
# -*-coding:utf-8-*-
import socket
import select
import time
EOL1 = b'\n\n'
EOL2 = b'\n\r\n'
response = b'HTTP/1.0 200 OK\r\nDate: Mon, 1 Jan 1996 01:01:01 GMT\r\n'
response += b'Content-Type: text/plain\r\nContent-Length: 13\r\n\r\n'
response += b'<html><head><title>title</title></head><body><p>Hello, world!</p></body></html>'
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serversocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
serversocket.bind(('0.0.0.0', 8080))
serversocket.listen(1) # the number of client that connect to server
serversocket.setblocking(0) # set 0 not block other block
serversocket.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
epoll = select.epoll()
epoll.register(serversocket.fileno(), select.EPOLLIN)
try:
connections = {}
requests = {}
responses = {}
while True:
events = epoll.poll(1)
for fileno, event in events:
if fileno == serversocket.fileno(): # if request come
connection, address = serversocket.accept() # waiting income connection
connection.setblocking(0) # none block
epoll.register(connection.fileno(), select.EPOLLIN) # register socket read event to epoll
connections[connection.fileno()] = connection # add connection to connections dict
requests[connection.fileno()] = b''
responses[connection.fileno()] = response # write data to responses dict
elif event & select.EPOLLIN: # when data in os's read buffer area
requests[fileno] += connections[fileno].recv(1024) # read data from connections
if EOL1 in requests[fileno] or EOL2 in requests[fileno]: # if http message
print('-' * 40 + '\n' + requests[fileno].decode()[:-2])
responses[fileno] += str(time.time())
epoll.modify(fileno, select.EPOLLOUT) # change file number to epoll out mode
elif event & select.EPOLLOUT: # if out mode
byteswritten = connections[fileno].send(responses[fileno]) # write data to os's write buffer
responses[fileno] = responses[fileno][byteswritten:] # get http response message
if len(responses[fileno]) == 0: # if file sent
epoll.modify(fileno, 0) # change file number to hup mode
connections[fileno].shutdown(socket.SHUT_RDWR) # set socket read and write mode shutdown
elif event & select.EPOLLHUP: # if message sent and file number in epoll is hup
epoll.unregister(fileno) # remove file number from epoll
connections[fileno].close() # close connection
del connections[fileno] # delete connection from connections dict
finally:
epoll.unregister(serversocket.fileno())
epoll.close()
serversocket.close()
Aber wenn ich Web-Browser öffnen und besuchen „http://localhost:8080/“, bekomme ich einige Daten wie diese <html><head><, ist es nicht vollständige Daten, es ist nur ein Teil meines data.What ist los in meinem Projekt. Mehr Infos sehen Bitte sehen Sie dieses Bild. 
Ja, ich habe es gefunden, ich möchte 130 schreiben, das ist ein Fehler. –
