PyCharm连接linux服务器,且每次按Ctrl+S后就自动同步代码:
 
①tools:Deployment→Configuration:+→比如hello,SFTP;
②选项卡Connectionhost如http://httpbin.org,User name保持默认的root,Password如1~6;③选项卡MappingsLocalPath填入要上传的项目文件夹,后俩path都填/;
④tools:Deployment→OptionsUpload下拉框选择On…Ctrl+S

一句代码搭建服务器:
 
①目标文件夹如www下进入cmd→python -m http.server --cgi 7788;
②同网段的电脑用浏览器输入本机IP(可ipconfig查询):7788,即可查看www目录结构(若有index.html文件,则默认打开它)。若上句代码用的是默认端口80,则浏览器端可不写【:80】。
③若www内有cgi-bin文件夹,其内有Python文件如test.py,用浏览器如本机的输入网址http://localhost:7788/cgi-bin/test.py,可运行此Python文件。
 
test.py的内容:
html='''
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="gb2312">
    <title>服务器</title>
</head>
<body>
<h1>hello,世界</h1>
