這篇文章主要介紹了Python3怎么開啟自帶http服務(wù)的相關(guān)知識,內(nèi)容詳細(xì)易懂,操作簡單快捷,具有一定借鑒價值,相信大家閱讀完這篇Python3怎么開啟自帶http服務(wù)文章都會有所收獲,下面我們一起來看看吧。
Python中自帶了簡單的服務(wù)器程序,能較容易地打開服務(wù)。
在python3中將原來的SimpleHTTPServer命令改為了http.server,使用方法如下:
1. cd www目錄
2. python -m http.server
開啟成功,則會輸出“Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) …”,表示在本機(jī)8000端口開啟了服務(wù)。
如果需要后臺運行,可在命令后加"&"符號,Ctrl+C不會關(guān)閉服務(wù),如下:
python -m http.server &
如果要保持服務(wù),則在命令前加nohup以忽略所有掛斷信號,如下:
nohup python -m http.server 8001
如果不使用默認(rèn)端口,可在開啟時附帶端口參數(shù),如:
python -m http.server 8001
則會在8001端口打開http服務(wù)。
可以使用http://0.0.0.0:8000/查看www目錄下的網(wǎng)頁文件,若無index.html則會顯示目錄下的文件。
也可以使用ifconfig命令查看本機(jī)IP并使用。
補(bǔ)充:python創(chuàng)建http服務(wù)
用java調(diào)用dll的時候經(jīng)常出現(xiàn) invalid memory access,改用java-Python-dll,
Python通過http服務(wù)給java提供功能。
Python3.7
通過 http.server.BaseHTTPRequestHandler 來處理請求,并返回response
filename為輸入日志名稱,默認(rèn)是同目錄下,沒有該文件會新創(chuàng)建
filemode a 是追加寫的模式,w是覆蓋寫
import logging
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
filename="hhh.txt",
filemode='a'
)
logging.info("xxxx")
pchar - ctypes.c_char_p
integer 用了 bytes(0),byref(ctypes.c_void_p(0)) 都OK,沒有更深入去研究,如有錯誤請指正。
import ctypes
from ctypes import *
dll = ctypes.windll.LoadLibrary('C:\xxx\xxx.dll')
print("dll版本號為 : "+ str(dll.GetVersion()) )
name = ctypes.c_char_p(b"gc")
roomno = ctypes.c_char_p(bytes(room.encode("utf-8")))
begintime = ctypes.c_char_p(bytes(begin.encode("utf-8")))
endtime = ctypes.c_char_p(bytes(end.encode("utf-8")))
cardno = ctypes.c_void_p(0)
dll.invoke...
要注意 必須有 response = response_start_line + response_headers + “ ” + response_body
拼接應(yīng)答報文后,才能給瀏覽器正確返回
# coding:utf-8
import socket
from multiprocessing import Process
def handle_client(client_socket):
# 獲取客戶端請求數(shù)據(jù)
request_data = client_socket.recv(1024)
print("request:", request_data)
# 構(gòu)造響應(yīng)數(shù)據(jù)
response_start_line = "HTTP/1.1 200 OK
"
response_headers = "Server: My server
"
response_body = "helloWorld!"
response = response_start_line + response_headers + "
" + response_body
print("response:", response)
# 向客戶端返回響應(yīng)數(shù)據(jù)
client_socket.send(bytes(response, "utf-8"))
# 關(guān)閉客戶端連接
client_socket.close()
if __name__ == "__main__":
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("", 8888))
server_socket.listen(120)
print("success")
while True:
client_socket, client_address = server_socket.accept()
print("[%s, %s]用戶連接上了" % client_address)
handle_client_process = Process(target=handle_client, args=(client_socket,))
handle_client_process.start()
client_socket.close()
另外一種http方式
#-.- coding:utf-8 -.-
from http.server import HTTPServer
import ctypes
from ctypes import *
# HTTPRequestHandler class
import http.server
import socketserver
import logging
# pyinstaller -F
class testHTTPServer_RequestHandler(http.server.BaseHTTPRequestHandler):
# GET
def do_GET(self):
logging.error('start make ')
str2 = str(self.path)
print("revice: " + str2)
if "xxx" in str2:
# todo 你的具體業(yè)務(wù)操作
if "xxx" in str2:
print("hahaha")
logging.error('hahaha')
# response_body = "0"
self.send_response(200)
# Send headers
self.send_header('Content-type','text/html')
self.end_headers()
# Send message back to client
message = "Hello world!"
# Write content as utf-8 data
self.wfile.write(bytes(message, "utf8"))
return
else:
print("1else")
self.send_response(200)
# Send headers
self.send_header('Content-type', 'text/html')
self.end_headers()
# Send message back to client
message = "Hello world222333!"
# Write content as utf-8 data
self.wfile.write(bytes(message, "utf8"))
return
def run():
print('starting server...')
logging.basicConfig(
level=logging.INFO,
format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
filename="http_make_card.txt",
filemode='a+'
)
# Server settings
server_address = ('127.0.0.1', 8888)
httpd = HTTPServer(server_address, testHTTPServer_RequestHandler)
print('running server...')
httpd.serve_forever()
run()
pip install pyinstaller
pyinstaller -F xxx.py 即可,當(dāng)前目錄下生成
1、No module named ‘http.server'; ‘http' is not a package
當(dāng)時自己建了一個py叫http,刪掉后正常
2、UnicodeDecodeError: ‘utf-8' codec can't decode byte 0xce in position 130: invalid continuat
另存為utf-8即可
