開啟Web服務(wù)
1.基本方式
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：
|
1
|
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：
|
1
|
nohup python -m http.server 8001 |
2.指定端口
如果不使用默認端口，可在開啟時附帶端口參數(shù)，如：
|
1
|
python -m http.server 8001 |
則會在8001端口打開http服務(wù)。
使用Web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IP并使用。
補充：python創(chuàng)建http服務(wù)
背景
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。
環(huán)境
Python3.7
通過 http.server.BaseHTTPRequestHandler 來處理請求，并返回response
打印日志
filename為輸入日志名稱，默認是同目錄下，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 logginglogging.basicConfig( level=logging.INFO, format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s', filename="hhh.txt", filemode='a')logging.info("xxxx") |
調(diào)用dll
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。

http方案一
要注意 必須有 response = response_start_line + response_headers + “\r\n” + response_body
拼接應(yīng)答報文后，才能給瀏覽器正確返回

打包exe

|
pip install pyinstaller |
pyinstaller -F xxx.py 即可，當前目錄下生成
坑
1、No module named ‘http.server'; ‘http' is not a package
當時自己建了一個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
以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持服務(wù)器之家。
